A rectangle and a square have the same area. a. The width of the rectangle is w inches. The length of the rectangle is 15 inches less than 4 times the width of the rectangle. Write a polynomial to represent the area of the rectangle. b. The side of the square is w inches. Write a polynomial to represent the area of the square. c. Write an equation such that the area of the rectangle is equal to the area of the square. d. Solve the equation in part (c) to find the side length of the square. e. What are the length and the width of the rectangle?

Answers

9514 1404 393

Answer:

  a) w(4w-15)

  b) w²

  c) w(4w -15) = w²

  d) w = 5

  e) 5 by 5

Step-by-step explanation:

a) If w is the width, and the length is 15 less than 4 times the width, then the length is 4w-15. The area is the product of length and width.

  A = w(4w -15)

__

b) If w is the side length, the area of the square is (also) the product of length and width:

  A = w²

__

c) Equating the expressions for area, we have ...

  w(4w -15) = w²

__

d) we can subtract the right side to get ...

  4w² -15w -w² = 0

  3w(w -5) = 0

This has solutions w=0 and w=5. Only the positive solution is sensible in this problem.

The side length of the square is 5 units.

__

e) The rectangle is 5 units wide, and 4(5)-15 = 5 units long.

The rectangle and square have the same width and the same area, so the rectangle must be a square.

Meters to centimeters

Answers

Answer:

It grows 221 centimeters in 13 weeks.

Step-by-step explanation:

Each meter has 100 centimeters.

A coral reef grows 0.17 m every week

So it grows 0.17*100 = 17 cm every week.

How much does it grow in 13 weeks?

17 cm every week for 13 weeks, so

17*13 = 221

It grows 221 centimeters in 13 weeks.

The area of a square is 1800 in2, how long is each diagonal?

Answers

9514 1404 393

Answer:

  60 in

Step-by-step explanation:

The area of a square can be computed as ...

  A = (1/2)d^2 . . . . where d is the length of the diagonal

For an area of 1800 in^2, the diagonal length can be found as ...

  1800 in^2 = 1/2d^2

  3600 in^2 = d^2

  d = √3600 in = 60 in

The length of each diagonal is 60 inches.

Cameron has a balance of $10,200 on his credit card. He threw the card away so he can never use it again. He has 3.5 years to pay off the balance. The interest rate on his card is 21%.

At the end of the 3.5 years, how much money in interest alone will Cameron have paid?

When Cameron finally pays off his credit card, how much will he have paid in all?

Answers

Answer:

the interest is $9,676.91 and the future value amount is $19,876.91

Step-by-step explanation:

The computation is shown below;

The future value is

= Present value × (1 + rate of interest)^number of years

= $10,200 × (1 + 0.21)^3.5

=  $19,876.91

Now the interest amount is

= Future value - present value

= $19,876.91 - $10,200

= $9,676.91

Hence, the interest is $9,676.91 and the future value amount is $19,876.91

A cooler contains 12 bottles of apple juice and 18 bottles of orange juice. You reach into the cooler without looking and pull out one bottle of apple juice. Then you reach into cooler and pull out another bottle of juice. What is the probability of pulling apple juice and then pulling another apple juice?

Answers

Answer:

P = 0.232

Step-by-step explanation:

In the cooler, we have 12 bottles of apple juice and 18 bottles of orange juice.

This adds up to a total of 30 bottles.

Now we want to find the probability of pulling a bottle of apple juice after you pulled one bottle of apple juice.

The probability of pulling a bottle of apple juice at the beginning is equal to the quotient between the number of apple juice bottles in the cooler and the total number of bottles in the cooler,

This means that 12 out of 30 are apple juice, then the probability of getting first a bottle of apple juice is:

p = 12/30

Now, we want to find the probability of getting another, we will do the same calculation than above, but now the number of bottles of apple juice is 11 (because we took one) and the total number of bottles is 29.

In this case, the probability is:

q = 11/29

The joint probability (the probability of both events happening) is equal to the product of the individual probabilities.

Then the probability of pulling apple juice and then pulling another apple juice is:

P = p*q = (12/30)*(11/29) = 0.232
