Answer:

390m^2

Step-by-step explanation:

The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area

a = 5m

b = 12m

c = 13m

L = 11m

First, we need to find the base area...

base area = (a*b)/2

(5*12)/2 = 30 m^2

Next, find the surface area

A = 11(5 + 12 +13) + 2*30 = 390 m^2

PLEASE RATE!! I hope this helps!!

nexus9112 [7]

Answer:

Blue = 12

Yellow = 9

Step-by-step explanation:

Given

Blue : Yellow = 4 : 3

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

Total = 4 + 3

Total = 7

The blue and the yellow pint can be represented individually as:

Blue = \frac{4}{7} * Green

Yellow = \frac{3}{7} * Green

Number of blue paint calculated last week is:

Blue = \frac{4}{7} * 21

Blue = {4} * 3

Blue = 12

Yellow = \frac{3}{7} * Green

Yellow = \frac{3}{7} * 21

Yellow = {3} * 3

Yellow = 9
