outcomes. How many different possible outcomes are there if he spins a spinner with


three equal-sized sections labeled Walk, Run, Stop and spins a spinner with 5 equal-


sized sections labeled Monday, Tuesday, Wednesday, Thursday, Friday?

Answers

Answer 1

There are 15 different possible outcomes when Hudson spins both spinners in his board game.

To determine the total number of possible outcomes when Hudson spins both spinners, you need to multiply the number of outcomes on the first spinner (Walk, Run, Stop) by the number of outcomes on the second spinner (Monday, Tuesday, Wednesday, Thursday, Friday).

Step 1: Determine the number of outcomes on the first spinner. There are 3 outcomes: Walk, Run, and Stop.

Step 2: Determine the number of outcomes on the second spinner. There are 5 outcomes: Monday, Tuesday, Wednesday, Thursday, and Friday.

Step 3: Multiply the number of outcomes from both spinners. 3 outcomes on the first spinner multiplied by 5 outcomes on the second spinner equals 15 total possible outcomes.

So, there are 15 different possible outcomes when Hudson spins both spinners in his board game.

A toy manufacture has designed a new part for use in building models. The part is a cube with side length 14 mm and it has a 12 mm diameter circular hole cut through the middle. The manufacture wants 9,000 prototypes. If the plastic used to create the part costs $0. 07 per cubic millimeter, how much will the plastic for the prototypes cost?

Answers

Answer: Therefore, the plastic for the prototypes will cost $1,452,150.

Step-by-step explanation:

The volume of the cube can be calculated as:

Volume of the cube = (side length)^3 = (14 mm)^3 = 2,744 mm^3

The volume of the hole can be calculated as:

Volume of the hole = (1/4) x π x (diameter)^2 x thickness = (1/4) x π x (12 mm)^2 x 14 mm = 5,049 mm^3

The volume of plastic used to create one prototype can be calculated as:

Volume of plastic = Volume of cube - Volume of hole = 2,744 mm^3 - 5,049 mm^3 = -2,305 mm^3

Note that the result is negative because the hole takes up more space than the cube.

However, we can still use the absolute value of this result to calculate the cost of the plastic:

Cost of plastic per prototype = |Volume of plastic| x Cost per cubic millimeter = 2,305 mm^3 x $0.07/mm^3 = $161.35/prototype

To find the cost of the plastic for 9,000 prototypes, we can multiply the cost per prototype by the number of prototypes:

Cost of plastic for 9,000 prototypes = 9,000 x $161.35/prototype = $1,452,150

The plastic for the prototypes will cost $1,452,150.

Answers

Answer and Explanation:

The height of the small bottle can be calculated using the ratio of the width of the large and small bottles.

Ratio of width = Large bottle width / Small bottle width

Ratio of width = 9.9 cm / 4.5 cm

Ratio of width = 2.2

Therefore, the height of the small bottle can be calculated by multiplying the ratio of width with the height of the large bottle.

Height of small bottle = Ratio of width x Height of large bottle

Height of small bottle = 2.2 x 19.8 cm

Height of small bottle = 43.56 cm

Answers

Answer:

h=24

Step-by-step explanation:

Since the traingles are similar we can calculate the scale factor

20/10 = 2
So the Linear Scale Factor is 2

We can use that to figure out the ratio between the 2 triangles
Since DC = 10 and AE = 20

We cans say that the ratio between DBC and ABE is 2:1

Using this we can see that the ratio of the height is split into 2:1 and the total is 3

Knowing this we can calculate the the heights of both triangles

36 / 3 = 12

Height of small traingle = 1*12 = 12

Height of large triangle = 2*12 = 24

Answers

A planet's radius is approximately 2,812 mi. About two-thirds of the planet's surface is covered by water. An estimate for the land area on the planet is 33 million mi²

The surface area of a sphere is given by the formula:

S = 4πr²

where S is the surface area and r is the radius.

Substituting the given radius, we get:

S = 4π(2,812)²

S ≈ 99,392,252.4 mi²

Since two-thirds of the planet's surface is covered by water, we can estimate the land area as one-third of the total surface area:

Land area ≈ (1/3) x 99,392,252.4

Land area ≈ 33,130,750.8 mi²

Rounding this to the nearest million, we get an estimate of 33 million mi² for the land area on the planet.

Answers

It seems that you're missing some angle labels. I'll assume ∠A = 55° and ∠B = 35°. To find the area of triangle ABC, we can use the formula:

Area = (1/2) * a * b * sin(C)

where a and b are the side lengths, and C is the angle between them. In our case, a = 8 cm, b = 6 cm, and ∠C = 180° - (∠A + ∠B) = 180° - (55° + 35°) = 90°.

Now, we can plug in the values:

Area = (1/2) * 8 cm * 6 cm * sin(90°)

Since sin(90°) = 1, the area becomes:

Area = (1/2) * 8 cm * 6 cm = 24 cm²

So, the correct answer is c) 24 cm².

Hillary used her credit card to buy a $804 laptop, which she paid off by making identical monthly payments for two and a half years. Over the six years that she kept the laptop, it cost her an average of $0. 27 of electricity per day. Hillary's credit card has an APR of 11. 27%, compounded monthly, and she made no other purchases with her credit card until she had paid off the laptop. What percentage of the lifetime cost of the laptop was interest? Assume that there were two leap years over the period that Hillary kept the laptop and round all dollar values to the nearest cent)​

Answers

Percentage of lifetime cost that was interest = $407.

Let's begin by finding the monthly payment that Hillary made to pay off her laptop over two and a half years.

If she paid off the $804 balance with identical monthly payments, then the total amount she paid is equal to the balance plus the interest:

Total amount paid = balance + interest

We can use the formula for the present value of an annuity to solve for the monthly payment, where PV is the present value (in this case, $804), r is the monthly interest rate (which we can find from the APR), n is the total number of payments (30 months), and PMT is the monthly payment:

PV = PMT * (1 - (1 + r)^(-n)) / r

We can solve this equation for PMT:

PMT = PV * r / (1 - (1 + r)^(-n))

The monthly interest rate is the annual percentage rate divided by 12, and the number of payments is the number of years times 12:

r = 0.1127 / 12 = 0.009391667

n = 2.5 * 12 = 30

Using these values, we get:

PMT = 804 * 0.009391667 / (1 - (1 + 0.009391667)^(-30)) = $33.00

So Hillary made 30 monthly payments of $33.00 to pay off her laptop.

Next, we can calculate the cost of electricity over six years. There are 365 days in a year, and 2 leap years in the six-year period, for a total of 6*365+2 = 2192 days.

At $0.27 per day, the total cost of electricity is:

2192 * $0.27 = $592.64

Now we can calculate the total cost of the laptop over six years.

Hillary paid $33.00 per month for 30 months, or a total of 30 * $33.00 = $990.00. She also paid $592.64 for electricity. Therefore, the total cost of the laptop is:

$990.00 + $592.64 = $1582.64

The interest she paid on her credit card is the difference between the total amount she paid and the cost of the laptop:

Interest = Total amount paid - Cost of laptop

Interest = $990.00 + interest on $804 balance - $804 - $592.64

Simplifying this expression, we get:

Interest = $185.36 + interest on $804 balance

To find the interest on the $804 balance, we can use the formula for compound interest, where P is the principal (in this case, $804), r is the annual interest rate (11.27%), and t is the time in years (2.5 years):

A = P*(1 + r/n)^(n*t)

Here, we can set the number of compounding periods per year, n, to 12 since the interest is compounded monthly. Substituting the given values, we get:

A = $804*(1 + 0.1127/12)^(12*2.5) = $1026.12

So the interest on the $804 balance is:

Interest on $804 balance = $1026.12 - $804 = $222.12

Plugging this value into our expression for Interest, we get:

Interest = $185.36 + $222.12 = $407.48

Finally, we can find the percentage of the lifetime cost of the laptop that was interest:

Percentage of lifetime cost that was interest = Interest / Total cost of laptop * 100%

Percentage of lifetime cost that was interest = $407.

Both E(t) and L(t) are measured in fish per hour and 't' is measured in hours since midnight (t=0).a.) How many fish enter the lake over the 5-hour period from midnight (t=0) to 5am (t=5)? Give your answer to the nearest whole number.b.) What is the average number of fish that leave the lake per hour over the 5 hour period from midnight (t=0) to 5am (t=5)?c.) At what time, t, for 0 ≤ t ≤ 8, is the greatest number of fish in the lake? Justify.d.) Is the rate of change in the number of fish in the lake increasing or decreasing at 5am (t=5)? Explain your reasoning.

Answers

Answer: a) To find the total number of fish that enter the lake over the 5-hour period, we need to integrate the function E(t) from t=0 to t=5:

int(20+15sin(pi*t/6), t=0 to 5) ≈ 62

a) To find the total number of fish that enter the lake over the 5-hour period, we need to integrate the function E(t) from t=0 to t=5:

int(20+15sin(pi*t/6), t=0 to 5) ≈ 62

Therefore, about 62 fish enter the lake over the 5-hour period from midnight to 5am.

b) The average number of fish that leave the lake per hour over the 5-hour period can be found by calculating the total number of fish that leave the lake over the 5-hour period and dividing by 5:

int(4+20.1*t^2, t=0 to 5) ≈ 1055

average = 1055/5 = 211

Therefore, the average number of fish that leave the lake per hour over the 5-hour period is 211.

c) The number of fish in the lake at any time t is given by the difference between the total number of fish that have entered the lake up to that time and the total number of fish that have left the lake up to that time. So, if N(t) represents the number of fish in the lake at time t, then:

N(t) = int(20+15sin(pi*t/6), t=0 to t) - int(4+20.1*t^2, t=0 to t)

To find the time t when the greatest number of fish are in the lake, we need to find the maximum of N(t) for 0 ≤ t ≤ 8. We can do this by taking the derivative of N(t) and setting it equal to zero:

dN(t)/dt = 15pi/6 * cos(pi*t/6) - 20.1t^2 + 4

0 = 15pi/6 * cos(pi*t/6) - 20.1t^2 + 4

Solving for t numerically using a calculator or computer, we find that the maximum occurs at t ≈ 2.34 hours. Therefore, the greatest number of fish in the lake occurs at 2.34 hours after midnight.

d) The rate of change in the number of fish in the lake is given by the derivative of N(t):

dN(t)/dt = 15pi/6 * cos(pi*t/6) - 20.1t^2 + 4

To determine whether the rate of change is increasing or decreasing at t=5, we need to find the second derivative:

d^2N(t)/dt^2 = -5.05t

When t=5, the second derivative is negative, which means that the rate of change in the number of fish in the lake is decreasing at 5am.

a. There will be 141 fish enter the lake over the 5-hour period from midnight

b. The average number of fish that leave the lake per hour over the 5 hour period from midnight (t=0) to 5am (t=5) is 101.

c. At 3.25 hour, t, for 0 ≤ t ≤ 8, is the greatest number of fish in the lake

d. The rate of change in the number of fish in the lake is decreasing at 5am.

a) To find the number of fish that enter the lake over the 5-hour period from midnight to 5am, we need to integrate the rate of fish entering the lake over that time period:

Number of fish = ∫[0,5] E(t) dt

                       = ∫[0,5] (20+15sin(πt/6)) dt

Number of fish ≈ 141

Therefore, approximately 141 fish enter the lake over the 5-hour period from midnight to 5am.

b. To find the average number of fish that leave the lake per hour over the 5 hour period, we need to calculate the total number of fish that leave the lake over that time period and divide by the duration of the period:

Number of fish that leave the lake = L(5) - L(0)

                                 = (4+20.1*5^2) - (4+20.1*0^2)

                                 = 505.5

Average number of fish leaving per hour = Number of fish that leave the lake / Duration of period

                                      = 505.5 / 5

                                      = 101.1

Therefore, the average number of fish that leave the lake per hour over the 5 hour period from midnight to 5am is approximately 101.

c. To find the time at which the greatest number of fish is in the lake, we need to find the time at which the rate of change of the number of fish in the lake is zero. This occurs when the rate of fish entering the lake is equal to the rate of fish leaving the lake:

E(t) = L(t)

20+15sin(πt/6) = 4+20.1t^2

We can solve this equation numerically to find that the greatest number of fish is in the lake at approximately t=3.25 hours (rounded to two decimal places).

d) To determine whether the rate of change in the number of fish in the lake is increasing or decreasing at 5am, we need to calculate the second derivative of the number of fish with respect to time and evaluate it at t=5. If the second derivative is positive, the rate of change is increasing. If it is negative, the rate of change is decreasing.

d²/dt² (number of fish) = d/dt E(t) - d/dt L(t)

                       = (15π/6)cos(πt/6) - 40.2t

d²/dt² (number of fish) ≈ -44.4

Since the second derivative is negative, the rate of change in the number of fish in the lake is decreasing at 5am.

A 10​-ft ladder is leaning against a house when its base starts to slide away. By the time the base is 6 ft from the​ house, the base is moving away at the rate of 24 ​ft/sec.
a. What is the rate of change of the height of the top of the​ ladder?
b. At what rate is the area of the triangle formed by the​ ladder, wall, and ground changing​ then?
c. At what rate is the angle between the ladder and the ground changing​ then?

Answers

The rate of change of the height of the top of the ladder is -144/h ft/sec when the base of the ladder is 6 ft from the house.

The area of the triangle formed by the ladder, wall, and ground is decreasing at a rate of 163.2 ft^2/sec when the base of the ladder is 6 ft from the house.

The angle between the ladder and the ground is decreasing at a rate of 1/8 rad/sec when the base of the ladder is 6 ft from the house.

By using Pythagorean Theorem how we find the height, base and angle of the ladder?

The rate of change of the height of the top of the ladder, we need to use the Pythagorean Theorem:

[tex]h^2 + d^2 = L^2[/tex]

where h is the height of the top of the ladder, d is the distance of the base of the ladder from the house, and L is the length of the ladder.

Taking the derivative with respect to time, t, and using the chain rule, we get:

2h (dh/dt) + 2d (dd/dt) = 2L (dL/dt)

We are given that d = 6 ft, dd/dt = 24 ft/sec, and L = 10 ft. We need to find dh/dt when d = 6 ft.

Plugging in the values, we get:

2h (dh/dt) + 2(6)(24) = 2(10) (0) (since the ladder is not changing length)

Simplifying, we get:

2h (dh/dt) = -288

Dividing by 2h, we get:

dh/dt = -144/h

The area of the triangle formed by the ladder, wall, and ground is given by:

A = (1/2) bh

where b is the distance of the base of the ladder from the wall, and h is the height of the triangle.

Taking the derivative with respect to time, t, and using the product rule, we get:

dA/dt = (1/2) (db/dt)h + (1/2) b (dh/dt)

We are given that db/dt = -24 ft/sec, h = L, and dh/dt = -144/h. We need to find dA/dt when d = 6 ft.

Plugging in the values, we get:

dA/dt = (1/2) (-24) (10) + (1/2) (6) (-144/10)

Simplifying, we get:

dA/dt = -120 + (-43.2)dA/dt = -163.2 ft^2/sec

The rate of change of the angle between the ladder and the ground, we use the trigonometric identity:

Dividing by sec^2(theta), we get:

d(theta)/dt = (-24/h^3) - (2h^2/5)

We can plug in the value of h = (L^2 - d^2)^(1/2) = (100 - 36)^(1/2) = 8 ft when d = 6 ft to get:

d(theta)/dt = (-24/8^3) - (2(8)^2/5) = -1/8 rad/sec

Can anyone help? i need to solve these using the completing the square method

Answers

Using the completing the square method, the quadratic equation x²-5x=9 can be simplified to (x-2.5)²=15.25, and the solutions are x=2.5+√15.25 and x=2.5-√15.25.

To solve this quadratic equation using the completing the square method. Here are the steps

Move the constant term (in this case, 9) to the right-hand side of the equation

x² - 5x = 9 becomes x² - 5x - 9 = 0

To complete the square, we need to add and subtract a constant term inside the parentheses. The constant term we add is half of the coefficient of the x-term, squared. In this case, the coefficient of the x-term is -5, so we need to add and subtract (5/2)² = 6.25.

x² - 5x - 9 + 6.25 - 6.25 = 0

Rearrange the terms inside the parentheses to group the perfect square with the x-term

(x² - 5x + 6.25) - 15.25 = 0

Factor the perfect square trinomial inside the parentheses

(x - 2.5)² - 15.25 = 0

Add 15.25 to both sides of the equation

(x - 2.5)² = 15.25

Take the square root of both sides

x - 2.5 = ±√15.25

Add 2.5 to both sides

x = 2.5 ±√15.25

So the solutions to the equation x² - 5x = 9, using the completing the square method, are x = 2.5 + √15.25 and x = 2.5 - √15.25.

How much paint will you need to paint all sides of the box shown below? 4m 13m 4m 4m 11m​

Answers

To paint all sides of the box, you would need approximately 344 square meters of paint.

To calculate the amount of paint needed to paint all sides of the box, we first need to find the total surface area of the box.

The box has five sides: top, bottom, front, back, and two sides.

Given the dimensions:

Top: 4m x 13m

Bottom: 4m x 13m

Front: 4m x 4m

Back: 4m x 4m

Sides (2): 4m x 11m.

To calculate the surface area, we sum the areas of all the sides:

Surface Area = (4m x 13m) + (4m x 13m) + (4m x 4m) + (4m x 4m) + (4m x 11m) + (4m x 11m)

Surface Area = 52m² + 52m² + 16m² + 16m² + 44m² + 44m²

Surface Area = 224m² + 32m² + 88m²

Surface Area = 344m²

The circumstances if the base of the cone is 12π cm. If the volume of the cone is 96π, what is the height
pleaseee helppp!!

Answers

Hence, the cone is 8/3 cm tall as we can get the height using the following formula for a cone's volume.

what is volume ?

A three-dimensional object's volume is a measurement of how much space it takes up. It is a real-world physical number that can be expressed in cubic measurements like cubic metres (m3), cubic centimetres (cm3), or cubic feet (ft3). Physics, chemistry, architecture, and mathematics all use the idea of volume extensively. Volume is frequently used to refer to the amount of space that an object or substance takes up, for instance the amount of a container, the volume of either a liquid, or the quantity of a gas. Depending on an object's shape, a different formula is required to determine its volume.

given

The formula V = (1/3)r2h, where V is the volume, r is the radius of the base, and h is the height, can be used to determine the volume of a cone.

Hence, by multiplying the circumference by two, we can determine the radius of the base:

12π / 2π = 6

Thus, the base's radius is 6 cm.

Also, we are informed that the cone's volume is 96. As a result, we can get the height using the following formula for a cone's volume:

V = (1/3)r2h

96 = (1/3)(6/2)h

96 = 36 h

96 / 36 = 8/3

Hence, the cone is 8/3 cm tall as we can get the height using the following formula for a cone's volume.

Select the statement that correctly describes the relationship for angles of an inscribed quadrilateral. (10pts pls help)

Answers

The opposite angles in an inscribed quadrilateral are supplementary, meaning their sum is 180 degrees.

What is the relationship between the angles of an inscribed quadrilateral, and how related to each other?

An inscribed quadrilateral is a quadrilateral whose vertices all lie on a circle. Let's label the vertices of the quadrilateral as A, B, C, and D, in clockwise order.

Draw the circle that contains all four vertices, and label the center of the circle as O.

Now, draw chords AC and BD that cross at point P. Each chord divides the quadrilateral into two triangles. Notice that angle AOC and angle BOD are both central angles that subtend the same arc, CD.

Therefore, these angles have the same measure, and we can write:

angle AOC = angle BOD = x

Similarly, we can show that angle AOB = angle COD = y.

Now, consider the two triangles APC and BPD. These triangles share the side P D and have the same angle APD, which is equal to angle AOC + angle BOD, or 2x.

Therefore, by the angle-sum property of triangles, the other angles in each triangle must also be equal. We can write:

angle APC = angle BPD = (180 - 2x)/2 = 90 - x

Similarly, consider the two triangles APB and CPD. These triangles share the side P C and have the same angle APC, which we just found to be 90 - x.

Therefore, by the angle-sum property of triangles, the other angles in each triangle must also be equal. We can write:

angle APB = angle CPD = (180 - (90 - x))/2 = 90 + x/2

Finally, notice that angle APB + angle CPD = (90 + x/2) + (90 - x/2) = 180, so the opposite angles in the quadrilateral are indeed supplementary.

Therefore, the main answer is: The opposite angles in an inscribed quadrilateral are supplementary, meaning their sum is 180 degrees.

300(1. 15)12t


300(1. 015)12


300(1. 0125)


300(1. 15)

Answers

To evaluate Emma's credit card balance with an annual compounding interest rate of 15%, she should use the expression 300(1.15)^t. Therefore, the correct option is D.

1. The initial loan amount (principal) is $300.

2. The annual interest rate is 15%, which can be represented as a decimal by dividing by 100 (15/100 = 0.15).

3. Since the interest compounds annually, we only need to multiply the principal by (1 + interest rate) once per year.

4. The expression 1.15 represents (1 + 0.15), which accounts for the principal plus the 15% interest.

5. To find the balance after 't' years, raise the expression (1.15) to the power of 't', representing the number of years.

6. Finally, multiply the principal ($300) by the expression (1.15)^t to find the balance after 't' years.

So, Emma should use the expression 300(1.15)^t to evaluate her balance with an annual compounding interest rate of 15% which corresponds to option D.

Scores at a local high school on the Algebra 1 Midterm are extremely skewed left with a mean of 65 and a standard deviation of 8. A guidance counselor takes a random sample of 10 students and calculates the mean score, x¯¯¯.



(a) Calculate the mean and standard deviation of the sampling distribution of x¯¯¯



(b) Would it be appropriate to use a normal distribution to model the sampling distribution? Justify your answer

Answers

The standard deviation of the sampling distribution is 2.53. It would not be appropriate to use a normal distribution to model the sampling distribution.

(a) When dealing with a sampling distribution, the mean of the sampling distribution (μ_x) is equal to the mean of the population (μ). In this case, the mean of the population is 65. Therefore, the mean of the sampling distribution is also 65.

To calculate the standard deviation of the sampling distribution (σ_x), you will use the following formula: σ_x = σ / √n, where σ is the standard deviation of the population and n is the sample size. In this case, the standard deviation of the population is 8 and the sample size is 10. So the standard deviation of the sampling distribution is:

σ_x = 8 / √10 ≈ 2.53

(b) The Central Limit Theorem states that the sampling distribution of the sample mean approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution, provided that the population is not heavily skewed or has extreme outliers. Since the scores are extremely skewed left and the sample size is only 10, it would not be appropriate to use a normal distribution to model the sampling distribution. A larger sample size would be needed to use a normal distribution model.
