The area of the square is 16 square units.
The area of the rhombus is 24 square units.
Part 1: Using the distance formula, we can find the lengths of the diagonals:
Diagonal AC = √[tex][(7-1)^2 + (2-10)^2[/tex]] = √(36 + 64) = √100 = 10
Diagonal BD = √[[tex](12-(-4))^2 + (12-0)^2[/tex]] = √(256 + 144) = √400 = 20
Part 2: The area of a rhombus can be calculated using the formula: Area = (diagonal 1 x diagonal 2)/2.
So, for this rhombus, the area = (10 x 20)/2 = 100 square units.
Part 3: The area formulas for a square and rhombus are not interchangeable because they have different ways of computing their areas. A square has all four sides equal in length, while a rhombus has opposite sides equal in length. The diagonals of a square bisect each other at right angles, and each diagonal divides the square into two congruent triangles, so the area of a square is simply side length squared (Area =[tex]s^2[/tex]). However, the diagonals of a rhombus bisect each other at right angles, but they do not necessarily divide the rhombus into congruent triangles. Therefore, the area of a rhombus is calculated using the lengths of the diagonals (Area = (diagonal 1 x diagonal 2)/2).
For example, let's consider a square with side length 4 units and a rhombus with diagonals 6 units and 8 units.
The area of the square = [tex]4^2 = 16[/tex]square units.
The area of the rhombus = (6 x 8)/2 = 24 square units.
As we can see, the formulas are not interchangeable.

Alejandro will deposit $1,750 in an account that earns 6. 5% simple interest every year. His sister Anallency will deposit $1,675 in an account that earns 7. 5% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. How much more money will Anallency have?
Anallency will have $134.46 more money than Alejandro after one year of their respective deposits.
How much more money will Anallency have than Alejandro after one year of their respective deposits?Alejandro and Anallency are depositing money in separate accounts with different interest rates. Alejandro is depositing $1,750 in an account that earns a simple interest rate of 6.5% per year, while Anallency is depositing $1,675 in an account that earns a compounded interest rate of 7.5% per year. After one year of their respective deposits, Anallency will have $134.46 more money than Alejandro.
The difference in interest earned between the two accounts is the reason for the difference in money earned by Alejandro and Anallency. Alejandro's account earns a simple interest rate, which means that he earns 6.5% of his initial deposit every year, regardless of how much interest he has already earned.
On the other hand, Anallency's account earns a compounded interest rate, which means that she earns interest on both her initial deposit and on any interest earned in previous years.
The formula for calculating simple interest is I = Prt, where I is the interest earned, P is the principal (or initial deposit), r is the interest rate, and t is the time in years. Using this formula, we can calculate that Alejandro will earn $113.75 in interest after one year.
The formula for calculating compounded interest is A = P(1 + r/n)^(nt), where A is the amount of money at the end of the time period, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
Using this formula, we can calculate that Anallency will have $248.21 more in her account than Alejandro after one year.

Tom only has one service bay.
a. Find the probability that there are no cars in the system.
b. Find the average number of cars in the system.
c. Find the average time spent in the system.
d. Find the probability that there are exactly two cars in the system
a. To find the probability that there are no cars in the system, we need to use the formula for the steady-state probability distribution of the M/M/1 queue:
P(0) = (1 - λ/μ)
where λ is the arrival rate (2 per hour) and μ is the service rate (3 per hour).
P(0) = (1 - 2/3) = 1/3 or 0.3333
Therefore, the probability that there are no cars in the system is 0.3333.
b. To find the average number of cars in the system, we can use Little's Law:
L = λW
where L is the average number of cars in the system, λ is the arrival rate (2 per hour), and W is the average time spent in the system.
We can solve for W by using the formula:
W = 1/(μ - λ)
W = 1/(3 - 2) = 1 hour
Therefore, the average number of cars in the system is:
L = λW = 2 x 1 = 2 cars
c. To find the average time spent in the system, we already calculated W in part b:
W = 1 hour
d. To find the probability that there are exactly two cars in the system, we need to use the formula for the steady-state probability distribution:
P(n) = P(0) * (λ/μ)^n / n!
where n is the number of cars in the system.
P(2) = P(0) * (λ/μ)^2 / 2!
P(2) = 0.3333 * (2/3)^2 / 2
P(2) = 0.1111 or 11.11%
Therefore, the probability that there are exactly two cars in the system is 11.11%.

If the mean weight of 4 backfield members on the football team is 234 lb and the mean weight of the 7 other players is 192 lb, what is the mean weight of the 11-person team?
The mean weight of the team is approximately ___ pounds.
(Round to the nearest tenth.)
Answer: The mean weight of the 11-person team is 207.3 pounds
Step-by-step explanation:
According to the question,
The mean weight of 4 backfield members = 234 lb
Therefore, the total weight of 4 backfield members = 4 × 234 = 936 lb
Similarly,
The mean weight of the 7 players = 192 lb
And the total weight of 7 players = 7 × 192 = 1344 lb
∴ Total weight of 11 players = (936 + 1344) lb = 2280 lb
We know that,
Mean = [tex]\frac{Total Sum}{Total number of variables}[/tex]
∴ To find the mean weight of the 11 players we need to divide the total weight by 11 :
Mean = [tex]\frac{2280}{11} = 207.27[/tex]
Rounding off to the nearest tenth we get,
Mean = 207.3
Hence, the mean weight of the team is approximately 207.3 pounds

Brainliest if correct!_A particle is projected vertically upwards from a fixed point O. The speed of projection is u m/s. The particle returns to O 4 seconds later. Find:
a) the value of u
b) the greatest height reached by the particle
c) the total time of which the particle is at a height greater than half its greatest height
Thank you so much!
The value of the velocity, u is 19.6 m/s.
The greatest height reached by the particle is 19.6 m.
The total time during which the particle is at a height greater than half its greatest height is 2.33 s.
What is the value of the velocity, u?a) To find the value of the velocity, u, we can use the formula for the time of flight of a vertically projected particle:
t = 2u/g
Since the particle returns to the same point after 4 seconds, we have:
2t = 4
Substituting the value of t in the first equation, we get:
u = gt/2 = 9.8 x 2
u = 19.6 m/s
b) To find the greatest height reached by the particle, we can use the formula for the maximum height reached by a vertically projected particle:
h = u^2/2g
Substituting the value of u, we get:
h = 19.6^2/(2 x 9.8)
h = 19.6 m
c) To find the total time during which the particle is at a height greater than half its greatest height, we can first find the height at which the particle is at half its greatest height:
h/2 = (u^2/2g)/2 = u^2/4g
Substituting the value of u, we get:
h/2 = 19.6^2/(4 x 9.8) = 24.01 m
So, the particle is at a height greater than half its greatest height when it is above 24.01 m.
Next, we can find the time taken by the particle to reach this height:
h = ut - (1/2)gt^2
24.01 = 19.6t - (1/2)9.8t^2
Solving this quadratic equation, we get:
t = 2.33 s or t = 4.10 s
The particle takes 2.33 s to reach a height of 24.01 m, and it takes another 1.67 s (4 - 2.33) to return to the ground.

[tex]\bar{X}=12.5[/tex]
μ = 13
Formula for the t-test statistics is
[tex]t = \frac{\bar{X}-\mu}{s/\sqrt{n} }[/tex]
t = (12.5 - 13)/(6.5/√400)
t = (- 0.5)/(6.5/20)
t = - 10/6.5
= -1.5388
Degree of freedom is 400 -1 = 399
α = 0.05
The p-value is p(t < -1.5385) = 0.062

Step 1: Answer
The point (2, 8) is the point (x1, y1) identified from the equation y - 8 = 3(x - 2).
Step 2: Explanation
The equation y - 8 = 3(x - 2) is in point-slope form, which is y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope of the line. In this case, the slope of the line is 3, which means that for every increase of 1 in the x-coordinate, the y-coordinate increases by 3.
Comparing the given equation with the point-slope form, we can see that x1 = 2 and y1 = 8. Therefore, the point (2, 8) is the point identified from the equation.

If the donation to charity b is 5/6 of the donation to charity d, charity d's donation is twice the donation to charity c and the ratio of donations for charity c to charity a is 3:4 then the donation to charity b is £1250.
Let's denote the donation to charity a as x. Then the donation to charity c is (3/4)x, and the donation to charity d is 2(3/4)x = (3/2)x.
We know that the donation to charity b is 5/6 of the donation to charity d, so:
donation to charity b = (5/6)(3/2)x = (5/4)x
We also know that the total donation is £4500, so we can set up an equation:
x + (3/4)x + (3/2)x + (5/4)x = £4500
Multiplying through by 4 to get rid of the fractions, we have:
4x + 3x + 6x + 5x = £18,000
18x = £18,000
x = £1000

A three digit number is such that twice the hundreds digit is more than the tens digit by 2. The unit digit is thrice the hundred digit. When the digits are reversed the number is increased by 594. Find the number.(5 marks)
Answer:
Step-by-step explanation:
Let the three-digit number be represented as $abc$, where $a$ is the hundreds digit, $b$ is the tens digit, and $c$ is the units digit.
From the problem, we have two equations:
Equation 1: $2a=b+2$
Equation 2: $c=3a$
We can use these equations to solve for $a$, $b$, and $c$.
Starting with Equation 1, we can isolate $b$ to get $b=2a-2$.
Next, we can substitute Equation 2 into Equation 1 to get $2a=3a-6+2$, which simplifies to $a=8$.
Using this value of $a$, we can now find $b$ and $c$. From Equation 2, we have $c=3a=24$. And from Equation 1, we have $b=2a-2=14$.
Thus, the original three-digit number is $abc=824$.
When we reverse the digits to get $cba=428$, we increase the number by 594, so we have $cba=abc+594=824+594=1418$.
Therefore, the answer is $\boxed{824}$.

Marsha is considering purchasing 3 points on a $350,000 home mortgage for 20 years. If she
purchases the 3 points, at a cost of 1 percent per point, her monthly mortgage would be
approximately $1,878.63. If she decides not to purchase any points, Mercedes' monthly
payment would be approximately $1,987.13. How much money will Mercedes save over the life
of the loan if she purchases the 3 points?
Marsha would save $26,040 over the life of the loan if she purchases the 3 points.
First, let's calculate the monthly payment if Marsha doesn't purchase any points. We can use a mortgage calculator or the PMT function in Excel to find;
PMT = $1,987.13
Now, let's calculate the monthly payment if Marsha purchases 3 points;
Loan amount = $350,000
Points cost = 3 points × 1% × $350,000 = $10,500
Effective loan amount = $350,000 - $10,500 = $339,500
Interest rate = 4.5% / 12 = 0.375%
Number of payments=20 years × 12 = 240
Using the PMT function, we get;
PMT = $1,878.63
So, by purchasing 3 points, Marsha can save;
$1,987.13 - $1,878.63 = $108.50 per month
Over the life of the loan, which is 20 years or 240 months, the total savings would be;
$108.50 × 240 = $26,040
Therefore, Marsha would save $26,040 amount of money.

10 foot ladder is leaning against a vertical wall when Jack begins
pulling the foot of the ladder away from the wall at a rate of 0.5
fr/s. how fast is the top of the ladder sliding down the wall?
We can use the Pythagorean theorem to relate the distances between the ladder, wall, and ground. Let's call the distance from the foot of the ladder to the wall "x", and the distance from the top of the ladder to the ground "y". Then, we know that:
x^2 + y^2 = 10^2
We can differentiate this equation with respect to time to get:
2x(dx/dt) + 2y(dy/dt) = 0
We're interested in finding dy/dt, the rate at which the top of the ladder is sliding down the wall. We know that dx/dt = 0.5 ft/s, so we can plug in these values and solve for dy/dt:
2x(dx/dt) + 2y(dy/dt) = 0
2(8)(0.5) + 2y(dy/dt) = 0 (since x = 8 based on the Pythagorean theorem)
dy/dt = -4 ft/s
So the top of the ladder is sliding down the wall at a rate of 4 ft/s.
When the 10-foot ladder is leaning against a vertical wall, it forms a right-angled triangle with the wall and the ground. As Jack pulls the foot of the ladder away from the wall at a rate of 0.5 ft/s, the top of the ladder slides down the wall. To find the rate at which the top of the ladder slides down, we can use the Pythagorean theorem:
a^2 + b^2 = c^2
where a is the distance from the foot of the ladder to the wall, b is the height of the ladder's top from the ground, and c is the length of the ladder (10 feet).
Differentiating both sides with respect to time (t), we get:
2a(da/dt) + 2b(db/dt) = 0
We know that da/dt = 0.5 ft/s. We need to find db/dt, which is the rate at which the top of the ladder slides down the wall. To do this, we need to find the values of a and b at a given moment. Since the problem doesn't provide this information, it's not possible to determine the exact value of db/dt. However, if you have the values of a and b, you can plug them into the equation and solve for db/dt.

how tall is each brick?
Since each of the bricks is the same exact size, then each brick is 0.6 meters tall.
To determine the height of each glowing brick, we need to divide the total height of the tower (5.4 meters) by the number of bricks (9). This gives us the average height of each brick.
Using the formula for division, we can write this as:
Height of each brick = Total height of tower / Number of bricks
Plugging in the given values, we get:
Height of each brick = 5.4 meters / 9 bricks
Simplifying this expression, we can cancel out the units of "bricks" to get:
Height of each brick = 0.6 meters

Tim made his mother a quilt. The width is 6 5 /7 ft and the length is 7 3 /5 ft. What is the area of the quilt?
The quilt's area is approximately 60.74 square feet.
How to calculate the quilt's area?To calculate the area of the quilt, we need to multiply the width by the length.
First, we need to convert the mixed numbers to improper fractions:
Width: 6 5/7 ft = (7 x 6 + 5)/7 = 47/7 ft
Length: 7 3/5 ft = (5 x 7 + 3)/5 = 38/5 ft
Now, we can multiply the width by the length:
Area = width x length
Area = (47/7) ft x (38/5) ft
Area = 2126/35 sq ft
Area ≈ 60.74 sq ft
Therefore, the area of the quilt is approximately 60.74 square feet.

a. A' (15, -10) b.
A' (-15, 10)
C. A' (-10, 15)
d. A' (10, -15)
Answer:
A
Step-by-step explanation:
Let's call the length of each of the other two sides x. Since the triangle is isosceles, it has two sides of equal length. Therefore, the perimeter of the triangle can be expressed as 6 + x + x Simplifying this equation, we get 2x + 6 We know that the perimeter is 22 cm so we can set up an equation and solve for x. 22 = 2x + 6 Subtracting 6 from both sides, we get 16 = 2x Dividing both sides by 2, we get x=8
The bike sarah wants to buy is now 40% off. the original price is $150. decide if you are missing the percent, part or whole. then use the appropriate formula to find the discount amount
The discount amount of the bike Sarah wants to buy is $60. The calculation was done by using the formula: Discount = Original price x Percent off.
To find the discount amount of the bike, we need to use the formula
Discount = Original Price x Discount Rate
where Discount Rate = Percent Off / 100
We know that the original price of the bike is $150 and it is now 40% off. So, the discount rate is
Discount Rate = 40 / 100 = 0.4
Substituting these values in the formula, we get:
Discount = $150 x 0.4 = $60
Therefore, the discount amount of the bike is $60.

Terrell arranges x roses at $3. 50 each with 10 carnations at $2. 25 each. He makes a bouquet of flowers that averages $3. 00 per flower. Choose an equation to model the situation
The equation models the situation described in the problem is 3.50x + 2.25(10) = 3 (x + 10) . The correct answer is C.
To model the situation described in the problem, we need to use an equation that represents the total cost of the flowers in terms of the number of roses (x) and the number of carnations (10). Let's assume that the cost of each flower is proportional to its price, and that the average cost per flower is the total cost divided by the total number of flowers (x + 10).
The cost of x roses at $3.50 each is 3.50x, and the cost of 10 carnations at $2.25 each is 2.25(10) = 22.50. Therefore, the total cost of the bouquet is:
Total cost = 3.50x + 22.50
The average cost per flower is given by:
Average cost = Total cost / (x + 10)
We are told that the average cost per flower is $3.00, so we can set up an equation:
3.00 = (3.50x + 22.50) / (x + 10) or 3.50x + 2.25(10) = 3 (x + 10)
This equation models the situation described in the problem. We can solve for x to find the number of roses needed to make a bouquet that meets the given conditions. The correct answer is C.

Albert and Makayla are each renting a car for one day. Albert’s rental agreement states that the car costs $35 per day and $0. 15 per mile driven. Makayla’s agreement states that the car she is renting costs $45 per day and $0. 10 per mile driven. Write an equation to determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals
To determine the number of miles, m, Albert and Makayla drive if they spend the same amount of money on their rentals, we can write an equation using the given information:
Albert's cost = $35 per day + $0.15 per mile driven
Makayla's cost = $45 per day + $0.10 per mile driven
Since they spend the same amount of money, we can set the costs equal to each other:
35 + 0.15m = 45 + 0.10m
Now, we need to solve the equation form, the number of miles driven:
1. Subtract 0.10m from both sides:
35 + 0.05m = 45
2. Subtract 35 from both sides:
0.05m = 10
3. Divide both sides by 0.05:
m = 200
So, if Albert and Makayla spend the same amount of money on their rentals, they both drive 200 miles.

 A customer is comparing the size of oil funnels in a store. The funnels are cone shaped. One funnel has a base with a diameter of 8 in. And a slant height of 12 in. What is the height of the funnel? Round your answer to the nearest hundredth. 
The height of the funnel is 11.31, under the condition that one funnel has a base with a diameter of 8 in. And a slant height of 12 in.
Here we have to apply the Pythagorean theorem to evaluate the height of the funnel. The Pythagorean theorem projects that the square of the hypotenuse (the slant height) is equal to the sum of the squares of the other two sides (the radius and height).
Now, we have a cone that has a base diameter of 8 inches which says that the radius is 4 inches. The slant height is 12 inches. Then the height is
h² + r² = l²
h² + 4² = 12²
h² = 144 - 16
h² = 128
h = √(128)
h ≈ 11.31
Hence, 11.31 inches is the approximate height of the funnel after rounding to the nearest hundredth.

2. How are the solutions to the inequality -2x [tex]\geq[/tex] 10 different fomt the solutions to -2x > 10? Explain your reasoning.
Therefore , the solution of the given problem of inequality comes out to be the solutions x = -6 or x = -10 would be acceptable.
What exactly is an inequality?Algebra, which lacking a symbol for this difference, can represent it using a pair or group of numbers. Equity usually comes after equilibrium. Inequality is bred by the persistent gap of standards. Equality and disparity are not the same thing. As was my least preferred symbol, notwithstanding knowing that the pieces are often not connected or close to one another. (). No matter how small the variations, they all affect value.
Here,
Finding values of x that cause the left side of the inequality to be bigger than the right side is necessary to make the inequality -2x > 10 true. Divide both sides by -2 and invert the inequality sign to achieve this:
=> -2x > 10
=> x < -5
The inequality is therefore true for any value of x that is less than -5. For instance, the solutions x = -6 or x = -10 would be acceptable.

Find the length of the midsegment of the trapezoid
2n-2
N+12
4n+6
Answer: To find the length of the midsegment of a trapezoid, you need to add the lengths of the two bases together and divide by 2.
The length of the top base is 2n-2 and the length of the bottom base is 4n+6.
Adding the two bases together gives:
(2n-2) + (4n+6) = 6n + 4
Dividing by 2 gives:
(6n + 4) / 2 = 3n + 2
Therefore, the length of the midsegment of the trapezoid is 3n + 2.
