Answer:

  $3785.53

Step-by-step explanation:

You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.

The amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...

  5000(1.073^8) ≈ 8785.53

Of that, 5000 is the principal amount, so the remainder is interest.

  interest = $8785.53 -5000

  interest = $3785.53

Becky will have to pay $3785.53 in interest.

Answer:

Sergio's strategy was to multiply the sum of the length and width of the rectangle by 2. This was one correct way to find the perimeter of the rectangle.

Jamie's strategy was to add the given measurements of the length and width of the rectangle together. This was another correct way to find the perimeter of the rectangle.

Karina's strategy was to multiply the given length of the rectangle by 2 and add this product to the width of the rectangle. This was NOT a correct way to find the perimeter of the rectangle, as it did not follow the formulas to finding the perimeter of a rectangle: l + w + l + w, or 2(l + w) and furthermore formulas that explain the same thing. Karina only multiplied the length by 2 and did not account for the width of the retangle which she should have done as well.  

Ethan's strategy was to multiply the width by 2, multiply the length by 2, and add these two products together to find the perimenter. This final strategy was correct, and can be used to find the perimeter of the rectangle.

Answer:

Step-by-step explanation:

You want two numbers that have a sum of 28 such that 4 times the lesser is 7 more than 3 times the greater.

Let the (lesser, greater) numbers be represented by (x, y).

  x + y = 28 . . . . . . their sum is 28

  4x -3y = 7 . . . . . . 4 times the lesser is 7 more than 3 times the greater

Using the first equation to write an expression for x, we have ...

  x = 28 -y

Substituting this into the second equation gives ...

  4(28 -y) -3y = 7

  112 -7y = 7 . . . . . . . . simplify

  105 = 7y . . . . . . . . . add 7y-7

  15 = y . . . . . . . . . . . divide by 7

  x = 28 -15 = 13

The lesser number is 13; the greater number is 15.

Additional comment

4 times the lesser number is 4·13 = 52.

3 times the greater number is 3·15 = 45.

52 is 7 more than 45, as required.

Surface area = 136 cm²    Volume = 80cm³

Step-by-step explanation:

Surface Area = face 1 + face 2 + face 3 + face 4+ face 5 + face 6

SA = 2(4) + 2(4) + 2(10) + 2(10) + 4(10) + 4(10)

SA = 8 + 8 + 20 + 20 + 40 + 40

SA = 16 + 40 + 80

Answer:

Step-by-step explanation:

tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.

James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.

so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.

James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

A unit rate means a rate for one of something.

It is written as a ratio with a denominator of one.

We have,

Tamika:

Rate of eating jellybeans = 12 jelly beans per 4 minutes.

12 beans = 4 minutes

Divide it by 4 into both sides

We get,

3 beans = 1 minute ___(1)

Tamika took 30 minutes to finish snack-size beans.

This means from (1),

3 x 30 jelly beans= 30 minutes

90 jelly beans = 30 minutes

There are 90 jellybeans in snack-size beans.

James:

Rate of eating the jellybeans = 28 jellybeans per 7 minutes

It can be written as:

28 jelly beans = 7 minutes

Multiplying 90/28 on both sides we get,

90 jelly beans = (90/28) x 7 minutes

90 jelly beans = 90/4 minutes = 22.5 minutes

This means James takes 22.5 minutes to finish snack-size jelly beans.

We see that,

The time took for Tamika to finish snack-size jelly beans = 30 minutes

The time took for James to finish snack-size jelly beans = 22.5 minutes

we have,

30 - 22.5 = 7.5

Thus,

James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

Step-by-step explanation: i know this it's hard to explain

It will take 1 3/4 gallons to paint the whole fence.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the expression of 3/4 divided by 1/8

3/4 x 8= 6

Therefore, The value of 7.89 divided by 2 is; 3.945

Now consider the gallons to paint the whole fence be x

1 1/4/x = 5/7

1.25/x = 5/7

then Cross multiply;

(5 × x) = (1.25 × 7)

5x = 8.75

x = 8.75/5

x = 1.75 = 1 3/4 gallons
