0. 85
(
1. 4
s
)
0. 85(1. 4s). Which expression could explain what happened to the price of the jacket?

Answers

The expression that explains what happened to the price of the jacket is 0.85(1.4s), which represents a 40% increase in price followed by a 15% discount.

The expression 0.85(1.4s) represents the current selling price of the jacket, which includes two price changes.

To explain what happened to the price of the jacket, we can break down the expression into two steps:

1. The first change was an increase by 40%, which can be represented as multiplying the original price "s" by 1.4 (100% + 40% = 140% or 1.4). So, the price after the first change is 1.4s.

2. The second change was a discount of 15%, which can be represented as multiplying the price after the first change by 0.85 (100% - 15% = 85% or 0.85). So, the price after both changes is 0.85(1.4s).

So, the expression that explains what happened to the price of the jacket is 0.85(1.4s), which represents a 40% increase in price followed by a 15% discount.

A traingle has side of 7cm and 18cm if the length of the third side is a whole number how many possible traingles are there explain your answer

Answers

Therefore, there are 13 possible triangles that can be formed with sides of 7cm, 18cm and a whole number as the third side.

How to get the number of triangles

Using the triangle inequality law, Let's denote the sides of the triangle as a, b, and c. In this case, we have:

a = 7 cm

b = 18 cm

c = the third side, a whole number

Now, we apply the triangle inequality theorem to these sides:

a + b > c

=> 7 + 18 > c

=> 25 > c

a + c > b

=> 7 + c > 18

=> c > 11

b + c > a

=> 18 + c > 7

=> c > -11

Since c is a whole number, the third condition is always true, as there are no negative whole numbers. Therefore, we only need to consider the first two conditions:

11 < c < 25

Now, we list the whole numbers that fall within 11 and 25 within this range:

these are listed and counted

12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24

There are 13 whole numbers in this range. So, there are 13 possible triangles with sides of 7 cm and 18 cm, and a third side that is a whole number.

create an expression to model the total cost for one dozen donuts where t represents the total surface area of the box in square feet.

help please :(​

Answers

The cost for one donut is $0.32, so the cost for one dozen donuts is:

12 donuts x $0.32/donut = $3.84

The cost for the cardboard box is $0.18 per square foot of cardboard, and there are 144 square inches in 1 square foot, so the cost per square inch of cardboard is:

$0.18 / 144 sq in = $0.00125/sq in

If t represents the total surface area of the box in square inches, then the cost of the box is:

t x $0.00125/sq in

To convert square inches to square feet, we divide by 144:

t/144 square feet x $0.18/square foot = t x $0.00125/sq in

Thus, the expression to model the total cost for one dozen donuts where t represents the total surface area of the box in square feet is:

Answers

The perimeter of the larger kennel will be twice as large as the perimeter of the original kennel.

To find the ratio of the perimeters of the original kennel to the larger kennel, we need to know how doubling the dimensions affects the perimeter.

Since the perimeter is the sum of all four sides, doubling each side will result in a perimeter that is double the original.

Therefore, the perimeter of the larger kennel will be two times the perimeter of the original kennel.

In mathematical terms:

Perimeter of larger kennel = 2 x perimeter of original kennel

Answers

The equation of the tangent plane to the surface at the point (u,v) = (3,U) is z = x + 34 + U.

To calculate TT, we need to find the partial derivatives of O(u,v) with respect to u and v:

TT = (∂O/∂u) x (∂O/∂v)
  = (2, 0, 8) x (0, 0, 1)
  = (-8, 0, 0)

To find n(u,v), we normalize TT:

n(u,v) = TT/|TT|
      = (-1, 0, 0)

At the point u=3, v=U, O(u,v) = (2u + 0.0 - 40, 8u) = (-34, 24).

To find the equation of the tangent plane, we first find the normal vector to the plane, which is n(u,v) = (-1, 0, 0). Then we use the point-normal form of the equation of a plane:

(-1)(x + 34) + 0(y - 24) + 0(z - U) = 0
-x - 34 + z - U = 0

There are 5 different green balls and 7 different red balls to be arranged in a row. how many ways can be arranged if all the green balls are separated

Answers

There are 86,400 ways to arrange 5 different green balls and 7 different red balls in a row if all the green balls are separated.

If all the green balls are separated, we can think of the green balls as dividers that separate the red balls into groups. Since there are 5 green balls, there will be 6 groups of red balls. For example, if there are 7 red balls, the arrangement might look like this:

| R R R R R R R |

The "|" symbols represent the green balls. Each group of red balls is between two green balls.

To count the number of arrangements, we can think of each group of red balls as a box, and the green balls as dividers between the boxes.

We can arrange the 6 boxes in a row in 6! = 720 ways, and we can arrange the 5 green balls in the remaining 5 positions in 5! = 120 ways. Therefore, the number of arrangements is:

6! x 5! = 720 x 120 = 86,400

97. Sri is weighing things on a scale, and he finds out that the following items have equal



weights:



5 marbles = 3 toy soldiers



7 toy soldiers = 5 plush chipmunks



3 plush chipmunks = 14 jujubes



How many jujubes equal the weight of one marble?

Answers

1 marble is equal in weight to 84 jujubes.

Let's start by writing down the given information in equations:

5m = 3s (where m represents one marble and s represents one toy soldier)

7s = 5c (where c represents one plush chipmunk)

3c = 14j (where j represents one jujube)

We want to find out how many jujubes equal the weight of one marble, so we need to eliminate all the other variables except for j and m. We can do this by using substitution and algebraic manipulation.

First, we can solve the second equation for s in terms of c:

7s = 5c

s = (5/7)c

Then, we can substitute this expression for s in the first equation:

5m = 3s

5m = 3(5/7)c

m = (3/7)c

Next, we can solve the third equation for c in terms of j:

3c = 14j

c = (14/3)j

Now we can substitute this expression for c in the previous equation:

m = (3/7)c

m = (3/7)(14/3)j

m = 2j

So we have found that one marble is equal in weight to 2 jujubes. But the question asks for the weight of one marble in terms of jujubes, not in terms of jujubes and toy soldiers and plush chipmunks. We can use the other equations to eliminate the other variables:

5m = 3s

5m = 3(5/7)c

5m = (15/7)c

m = (3/7)c

7s = 5c

7s = 5(14/3)j

s = (10/3)j

Putting this all together:

m = (3/7)c

m = (3/7)(7s/5)

m = (3/5)s

m = (3/5)(10/3)j

m = 2j

So we have found that one marble is equal in weight to 2 jujubes. Finally, we can use the third equation to find how many jujubes are equal in weight to 1 marble:

3c = 14j

c = (14/3)j

m = (3/7)c

m = (3/7)(14/3)j

m = 2j

1 marble = 2 jujubes

1 jujube = 1/2 marble

1 marble = 2 jujubes = 2(84) = 168 jujubes

Therefore, one marble is equal in weight to 84 jujubes.

Calculate ∑ (-1)^k pi^2k/2k

Answers

To calculate ∑ (-1)^k pi^2k/2k, we can use the power series expansion for the cosine function:

cos(x) = ∑ (-1)^n x^(2n) / (2n)!

We can substitute pi^2 for x in this formula to get:

cos(pi^2) = ∑ (-1)^n (pi^2)^(2n) / (2n)!
= ∑ (-1)^n pi^(4n) / (2n)!

Now we can compare this to the original series we want to evaluate:

∑ (-1)^k pi^2k/2k = ∑ (-1)^n pi^(2n) / (2n)

We notice that the powers of pi in the two series match up, but the coefficients are different. However, we can use the identity cos(pi^2) = (-1)^n to rewrite the series we want to evaluate as:

∑ (-1)^n pi^(2n) / (2n) = ∑ (-1)^n pi^(4n) / (2n)! * (2n) / pi^2n

= pi^2 / 2 * ∑ (-1)^n pi^(4n) / (2n)!

Now we can substitute our expression for cos(pi^2) into this equation to get:

∑ (-1)^k pi^2k/2k = pi^2 / 2 * cos(pi^2)

= pi^2 / 2 * (-1)^n

Therefore, the value of the series is (-1)^n * pi^2 / 2.
To calculate the sum ∑ (-1)^k (pi^2k)/(2k), it is important to recognize that this is an alternating series with a general term given by a_k = (-1)^k (pi^2k)/(2k).

However, the question seems incomplete, as there is no specified range for the sum (i.e., the values of k). If you provide the range of k for which this sum is to be calculated, I would be glad to help you further.

The question is: Sam, Mike, and Cindy are in a lottery drawing for housing with 40 other students to choose their dorm rooms. If the students are chosen in random order, what is the probability that Sam is chosen first, Mike second, and Cindy third?

To find the probability, we need to consider the total possible ways the students can be chosen and the specific arrangement we want (Sam first, Mike second, and Cindy third). There are a total of 43 students, so there are 43! (43 factorial) ways to arrange them.

For the specific arrangement we want:
- There is 1 way to choose Sam first (out of 43 students).
- After choosing Sam, there is 1 way to choose Mike second (out of the remaining 42 students).
- After choosing Mike, there is 1 way to choose Cindy third (out of the remaining 41 students).

So, there is a total of 1 × 1 × 1 = 1 way to have the specific arrangement we want.

Now, we can calculate the probability by dividing the number of ways to get the specific arrangement by the total number of arrangements:

Probability = (1 way for the specific arrangement) / (43! total arrangements) = 1/(43!)

Trees remaining = 1177.38 - 36.25(time)
where "Trees remaining" is the number of trees remaining and "time" is the number of years since harvesting began.
b) To find during which year the owners of the farm will stop harvesting when only 1000 trees remain, we can substitute "1000" for "Trees remaining" in the regression equation and solve for "time":
1000 = 1177.38 - 36.25(time)
Solving for "time", we get:
time = (1177.38 - 1000) / 36.25
time ≈ 4.89 years
Therefore, the owners of the farm will stop harvesting when only 1000 trees remain during the fifth year of harvesting.

If the sides of a rectangle are in the ratio 3:4 and the length of the diagonal is 10 cm, find the length of the sides

Answers

Answer: Let's use the Pythagorean theorem to solve this problem.

Let x be the common factor of the ratio 3:4, so the sides of the rectangle are 3x and 4x.

The Pythagorean theorem states that for any right triangle, the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse (the longest side).

So, for the rectangle with sides 3x and 4x, we have:

(3x)^2 + (4x)^2 = (diagonal)^2

9x^2 + 16x^2 = 100

25x^2 = 100

x^2 = 4

Taking the square root of both sides, we get:

x = 2

Therefore, the sides of the rectangle are:

3x = 3(2) = 6 cm

4x = 4(2) = 8 cm

So, the length and width of the rectangle are 6 cm and 8 cm, respectively.

Completing the table of values

The equation of the function is given as

y = x²/3 + 6/x² - 5

To complete the table of values, we set x = 1, 1.5, 4 and 5

So, we have

y = 1²/3 + 6/1² - 5 = 1.33

y = 1.5²/3 + 6/(1.5²) - 5 = -1.58

y = 4²/3 + 6/(4²) - 5 = 0.71

y = 5²/3 + 6/(5²) - 5 = 3.57

Solving the x values from the graph

The x and the y intervals are given as

0 ≤ x ≤ 5 and -5 ≤ y ≤ 4

See attachment for the graph and the labelled points

Estimating x²/3 + 6/x² - x - 3 = 0

We have

y = x²/3 + 6/x² - 5

Set y = x - 2

x²/3 + 6/x² - 5 = x - 2

So, we have

x²/3 + 6/x² - x - 3 = 0

This means that y = x - 2

From the graph, we have x = {1.28, 4.76}

Estimating x²/3 + 6/x² - x = 0

We have

y = x²/3 + 6/x² - 5

Set y = x - 5

x²/3 + 6/x² - 5 = x - 5

So, we have

x²/3 + 6/x² - x = 0

This means that y = x - 5

From the graph, we have x = undefined

It has no solution because the line does not intersect with the curve

Estimating x²/3 + 6/x² - 5 = 0

We have

y = x²/3 + 6/x² - 5

Set up the partial fraction decomposition for a given function. Do not evaluate the coefficients. f(x) = 16x3 + 12x2 + 10x + 2 / (x4 – 4x2)(x2 + x + 1)2(x2 – 3x + 2)(x4 + 3x2 + 2)

Answers

We can decompose the given rational function as follows:

f(x) = (16x^3 + 12x^2 + 10x + 2) / [(x^4 – 4x^2)(x^2 + x + 1)^2(x^2 – 3x + 2)(x^4 + 3x^2 + 2)]

To find the partial fraction decomposition, we first factor the denominator completely:

x^4 – 4x^2 = x^2(x^2 – 4) = x^2(x – 2)(x + 2)

x^2 + x + 1 = (x + 1/2)^2 + 3/4

x^2 – 3x + 2 = (x – 1)(x – 2)

x^4 + 3x^2 + 2 = (x^2 + 1)(x^2 + 2)

Substituting these factorizations into the denominator, we get:

f(x) = (16x^3 + 12x^2 + 10x + 2) / [x^2(x – 2)(x + 2)(x + 1/2)^2(3/4)^2(x – 1)(x – 2)(x^2 + 1)(x^2 + 2)]

We can now write the partial fraction decomposition as:

f(x) = A/x + Bx + C/(x – 2) + D/(x + 2) + E/(x + 1/2) + F/(x + 1/2)^2 + G/(x – 1) + H/(x^2 + 1) + I/(x^2 + 2)

where A, B, C, D, E, F, G, H, and I are constants to be determined.

Note that the term E/(x + 1/2) has a repeated linear factor (x + 1/2)^2, so we need to include a second term F/(x + 1/2)^2 in the decomposition.

If there is one to one correspondence between two sets, we say that the sets have the same "size" or the same ____________________

Answers

If there is a one-to-one correspondence between two sets, we say that the sets have the same "size" or the same "cardinality."

Cardinality is a term used in mathematics and set theory to describe the size or number of elements in a set. It refers to the property of a set that determines how many objects it contains. For example, the cardinality of the set {1, 2, 3} is 3, because it contains three elements. The cardinality of a set can be finite (if it has a specific number of elements) or infinite (if it contains an uncountable number of elements).

Cardinality is usually denoted using the vertical bar notation |A|, where A is the set in question. For example, if A = {a, b, c}, then |A| = 3.

Cardinality is an important concept in mathematics, especially in areas such as set theory, combinatorics, and number theory. It is used to compare the sizes of different sets and to determine the properties of operations that involve sets, such as union, intersection, and complement.

Cuál es el valor de la razón del cambio cuando metemos un vaso de agua al tiempo al congelador por 15 minutos?

Answers

The value of the rate of change when we put a glass of water at room temperature is 1/3.

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another.

The connection defining how one quantity changes in response to the change in another quantity is given by the rate of change formula. The formula for calculating the rate of change from y coordinates to x coordinates is y/x = (y2 - y1)/. (x2 - x1 ).

Rate of change  = change in temperature / time
