raise the product of 36 and 9 to the power of the sum of 2 and 4

Answers

Answer:

1.15683 1381 * 10^15

Step-by-step explanation:

To get the answer, first, get the product of 36 and 9

This can be obtained by multiplying 36 with 9

36 * 9 = 324

We then raise 324 to the power of the sum of 2 and 4

The sum of 2 and 4 is gotten by adding 2 to 4

So,

2 + 4=6

Therefore, 324 raised to the power of 6

= 1.15683 1381 * 10^15

Answer:

96 loaves

Step-by-step explanation:

6 hours is 360 minutes. Divide that by 45 min equals 8. If he can bake 12 every 45 min, then he can bake 8 x 12 loaves in 6 hours or 96 loaves.

Answer:

A, 96 loaves of bread

Step-by-step explanation:

So first off, since the rate is in minutes and not hours, you would first find how many minutes are in 6 hours. 60 minutes per hour multiplied by 6 hours gets you 360 minutes. You would now divide 360 by 45, and that would get you 8. You now have 8 units of 45 minutes, if that makes sense. You would now multiply 8 by 12, and get 96 loaves of bread.

The length of a rectangle is 3 more than 3 times its width. The perimeter of the rectangle is 174 inches. What is the length of the rectangle?

Answers

Answer:

l = w + 3cm

l = w + 3cmp = 2l + 2w = 58cm

l = w + 3cmp = 2l + 2w = 58cm Solve by substitution:

l = w + 3cmp = 2l + 2w = 58cm Solve by substitution:2l + 2w = 58 ⇒ 2(w + 3) + 2w = 58

l = w + 3cmp = 2l + 2w = 58cm Solve by substitution:2l + 2w = 58 ⇒ 2(w + 3) + 2w = 58⇒ 2w + 6 + 2w = 4w + 6 = 58

l = w + 3cmp = 2l + 2w = 58cm Solve by substitution:2l + 2w = 58 ⇒ 2(w + 3) + 2w = 58⇒ 2w + 6 + 2w = 4w + 6 = 58⇒ 4w = 52 ⇒ w = 13

l = w + 3cmp = 2l + 2w = 58cm Solve by substitution:2l + 2w = 58 ⇒ 2(w + 3) + 2w = 58⇒ 2w + 6 + 2w = 4w + 6 = 58⇒ 4w = 52 ⇒ w = 13 Plug back in:

If the measure of the width is 21 inches. Then the measure of the length of the rectangle will be 66 inches.

What is a rectangle?

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The length of a rectangle is 3 more than 3 times its width. The perimeter of the rectangle is 174 inches.

Then the length of the rectangle will be

We have

L = 3W + 3

Then the perimeter will be

P = 2(L + W)

174 = 2 (3W + 3 + W)

87 = 4W + 3

84 = 4W

W = 21 inches

Then the length will be

L = 3W + 3

L = 3 x 21 + 3

L = 63 + 3

L = 66 inches
