The surface area of the triangular prism is: B. 72 sq. ft
<h3>Surface Area of a Triangular Prism</h3>
- The surface area of a triangular prism is given by the formula: SA = bh + (s1+s2+s3)H
- Where, b is the base, h is the height, and s1+s2+s3 is the perimeter of the triangular base, H is the length of the prism.
Thus, given the triangular prism as shown in the diagram attached below, we have the following:
b = 4 ft
h = 3 ft
H = 5 ft
s1 + s2 + s3 = 3 + 4 + 5 = 12 ft
Surface area = 4×3 + (12)5 = 12 + 60 = 72
Therefore, the surface area of the triangular prism is: B. 72 sq. ft

Answer:
15,000 people
Step-by-step explanation:
This is the question of ratio, it is the quantitative relationship of two number.
In this survey a ratio of 66 people out of 110 is defined as living in apartment, based on this ratio we can estimate the total numbers of people living in apartments.
Total population of the town = 25,000 people
Ratio of people living in apartment = 66 / 110 = 0.6
Town people living in apartment = 25,000 x 0.6 = 15,000 peoples
Answer:
x = 4
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 8 when x = 10
k = yx = 8 × 10 = 80
y = 
← equation of variation
When y = 4, then
4 = ( multiply both sides by x )
4x = 80 ( divide both sides by 4 )
x = 20
