Answer:
Answer C
Step-by-step explanation:
Formula
Volume = pi * r^2 * h
Givens
Solution
- V = pi * 5^2 * 12
- V = pi * 25 * 12
- V = 300 pi
Answer = C
Answer:
0.324m^2 ; 18 ft
Step-by-step explanation:
Given the triangle :
Base (b) of triangle = 54cm
Height (h) of triangle = 1.2m
Area(A) of a triangle is given by:
0.5 * base * height
Base = 54cm = 54/100 = 0.54 m
Therefore,
A = 0.5 * 0.54m * 1.2m
A = 0.324m^2
2.) Average of the two bases in the trapezoid :
From the trapezium Given :
Base 1 = 15 feets
Base 2 = 7 yards
1 yard = 3 Feets
Therefore, base 2 in Feets = 7 * 3 = 21 Feets
Average of the two bases :
(21 Feets + 15 Feets) / 2
= 36 Feets / 2
= 18 Feets
Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
Wouldn’t be 0 because that’s where the line cross the middle line
