Hi there!

In order to solve this problem, we'll need to set up a proportion. The proportion we are going to use is x/120 = 50/100. Next, we'll cross-multiply, giving us 100x = 6000. Lastly, we'll divide each side by 100, giving us 60 5th graders that have a dog.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Hello!

First you have to convert the decimal into a percent

50% = 0.50

Multiply this by the amount of students.

120 * 0.50 = 60

The answer is 60

Hope this helps!

katrin2010 [14]

*See diagram in the attachment

Answer:

27 inches

Step-by-step explanation:

Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches

Perimeter of rectangle = 2(L + W)

L = 11 in.

W = 7 in.

Perimeter of rectangle = 2(11 + 7) = 36 in.

Let perimeter of the triangle be represented by x

Therefore:

36 + x = 63

Subtract 36 from each side

x = 63 - 36

x = 27

Perimeter of triangle = 27 inches

Ratling [72]

Answer:

L = 70

W = 32

Step-by-step explanation:

P = 2L + 2W

P 204 feet

W = x

L = 2x + 6

P = 2L + 2W

P = 2*(2x + 6) + 2*x

P = 4x + 12 + 2x

P = 6x + 12

But we know that P = 204 So 6x + 12 = 204

6x + 12 = 204 Subtract 12 from both sides

6x + 12 - 12 = 204 - 12 Collect like terms on the right

6x = 192 Divide by 6

x = 192/6

x = 32

Answer

W = 32

L = 2*W + 6

L = 2*32 + 6

L = 64 + 6

L = 70
