Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.
Given:
Compound ratio of 7:5 and 8:x is 84:60.
To find:
The value of x.
Solution:
Compound ratio of 7:5 and 8:x is 84:60.
By cross multiplication, we get
Divide both sides by 1420.
Therefore, the value of x is 8.
Find f (3) when f (x) =2x is the same as finding u when x= 3 ,for y=2x
to evaluate a function substitute the input (the given number or expression ) for the functions variable(place holder x). Replace the x with the number or expression
G
If it’s wrong I’m sorry but I’m pretty sure it’s G
Answer:
<h2>
17.6ft²</h2>
Step-by-step explanation:
The formula for calculating the surface area of a triangular prism is expressed as shown below:
SA= bh + pH
b= base of the triangle
h- height of the triangle
p= perimeter of the triangle
H= height of the prism
Given b = 1foot
h = 2feet
perimeter of the triangle = sum of all its sides = 1ft + 2ft + 2.2ft
p = 5.2ft
H = 3ft
Substituting the values into the formula for finding the surface area:
SA = 1(2)+5.2(3)
SA = 2+15.6
SA = 17.6ft²
The surface area of the triangular prism is 17.6ft²
