Each base of a triangular prism is a right triangle with side lengths 3 inches, 4 inches, and 5 inches. The height of the prism is 20 inches. What is the surface area of the prism?

252 inches

Step-by-step explanation:

Step 1:finding the area of triangle

b*h*1/2=3*4*1/2 but since there are two right angles in a triangular prism because of the two sides then its just 3*4 which is 12.

Step 2:finding the perimeter of the right angle

so 3,4 and 5 are known to be part of the right angle sp that means 3+4+5=12

Step 3:multiplying the height and perimeter of the triangular prism

20*12=240

Step 4;(A.K.A the final step)Adding the remaining numbers together.

240+12=252 inches

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
