C: 3.0

Step-by-step explanation:

You can write a ratio as a fraction (12/4). Write it as a fraction then just do the math.

12/4 = 3

C: 3.00

Explanation:

The ratio of 12 boys and 4 girls is 12:4

A ratio is basically a fraction so it is just 12/4

To convert a fraction to a decimal is by dividing the numerator by the denominator.

12 / 4 = 3

Therefore, the ratio of 12 boys and 4 girls written as a decimal is 3

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
