Answer:

20y

Step-by-step explanation:

Area of rectangle = area of square

=> length * breadth = side²

=> 50y * 8y = side²

=> 400y² = side²

=> (20y)² = side²

=> 20y = side length of square

Let k be the side length of the square.
Since the area of the rectangle and the square is equal,
8yx50y=k^2
Or,400y^2=k^2
or,k=20y

Hamish and Harry work as plumbers. Harry earns a dollar more than the amount Hamish earns per hour. The amount Harry earns per hour is less than the amount Hamish earns per hour. How much does each of them earn per hour? A. Hamish earns $18 per hour, and Harry earns $23 per hour. B. Hamish earns $19 per hour, and Harry earns $24 per hour. C. Hamish earns $21 per hour, and Harry earns $25 per hour. D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Answers

Answer:

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Step-by-step explanation:

Hamish and Harry work as plumbers. Harry earns a dollar more than 5/4 the amount Hamish earns per hour. The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour. How much does each of them earn per hour?

Hamish earnings per hour = x

Harry earnings = 1 + 5/4x

The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour

Harry also earns = 7/5x - 2

Equate both Harry's earnings

1 + 5/4x = 7/5x - 2

Collect like terms

1 + 2 = 7/5x - 5/4x

3 = 28x-25x/20

3 = 3/20x

Divide both sides by 3/20

x = 3 ÷ 3/20

= 3 × 20/3

x = 20

Hamish earnings per hour = x

= $20

Substitute Harry's earnings into 7/5x - 2

= 7/5 × 20 - 2

= 28 - 2

= 26

Harry's earnings = $26

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

If Alyssa makes $10 a week and has $70 right now how long will it take her to have $1750?

Answers

Answer:

168 weeks

Step-by-step explanation:

Come up with an equation, I came up with 10x + 70 = 1750

Because she already has 70$ and x = the amount of weeks.

Now all you have to do is solve.

10x + 70 = 1750

      - 70     -70

------------------------

10x = 1680

10/10    1680/10 = 168

x = 168

The gas tank on a car holds 13.4 gallons. If the car goes 335 miles on a single tank, how many miles per gallon does the car get? Provide an explanation of what the final answer means, in terms of the given problem. Show all work.

chile..

Answers

Answer:

The car gets 25 miles per gallon.

It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.

Step-by-step explanation:

"Miles per gallon" is calculated by dividing the number of miles by the number of gallons.

mpg = (335 miles)/(13.4 gallons) = 25 miles per gallon

Answer:

The car gets 25 miles per gallon.

It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.

Answer:

25

Step-by-step explanation:

You need to divide 335 miles by 13.4 to find the miles per gallon. 335 miles divided by 13.4 gallons is 25. So for every 25 miles you use 1 gallon.

Al and Angela both took out loans from the bank for $2,000 to help with their bills. Al's loan was calculated with a simple interest rate of 14% and Angela's loan had an interest rate of 13% that compounded annually. They each paid off their loans in 5 years. Who repaid the bank more money and how much more did they repay?

Answers

Answer:

Angela  $3680

Step-by-step explanation:

For Al's loan (simple interest )

p=$2000

rate=14%= 14/100= 0.14

time t= 5years

A=p(1+rt)]

A=2000(1+0.14*5)

A=2000(1+0.7)

A=2000(1.7)

A=$3400

For Angela  loan (compounded interest )

p=$2000

rate=13%= 14/100= 0.13

time t= 5years

A=p(1+r)^t

A=2000(1+0.13)^5)

A=2000(1+0.13)^5

A=2000(1.13)^5

A= 2000*1.84

A=$3680

) Suppose you are installing a wood floor in a square room. The cost to install the floor is $9 per square foot. The area of the room is given by the function A(x) = x 2 and the cost per square foot is given by the function C(A) = 9A. Which function can be used to find the total cost to install the wood floor? A) A(C(x)) B) C(A(x)) C) x(A(C)) D) x(C(A))

Answers

Answer:

The correct option is;

B) C(A(x))

Step-by-step explanation:

The given information are;

The cost to install the floor per square foot = $9

The area of the room is given by the function A(x) = x²

The function for the cost per square foot = C(A) = 9·A

We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)

∴ The total cost to install the wood floor = $9 × x²

Given that A(x) = x², we have;

The total cost to install the wood floor = $9 × A(x)

Also, given that C(A) = 9·A, we have;

C(A(x)) = 9·A(x)

Therefore;

The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

Answers

Answer:

a=2b-x

Step-by-step explanation:

Simplifying
2x + 2a = 4b

Reorder the terms:
2a + 2x = 4b

Solving
2a + 2x = 4b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x

Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x

Divide each side by '2'.
a = 2b + -1x

Simplifying
a = 2b + -1x

step one:

let the number of Blu-rays  be b and

DVDS be d,

step two:

given that Blu-rays cost $25.99each and

DVDS cost $15.99 each,

we can model the cost of the Blu-rays and DVDS, as

100=25.99b+15.99d

hence the expression for the number of Blu-rays and DVDS, is given as
