Answer:
x = 117
Step-by-step explanation:
Given
11 -
= 0 ( subtract 11 from both sides )
-
= - 11 ( square both sides )
(-
)² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117
The answer to your question is 3 to the 3rd power and 5 to the 2nd power. The reason why that's your answer is because there are three 3s so instead of doing 3*3*3 you can just simply do 3 to the 3rd power and do the same thing to the 5. You can see that there are two fives so you do 5 to the 2nd power.
Hope this helps:)
Answer:
The difference in the amount of wax needed is 84.78 in³ (84.78 cubic inches)
Step-by-step explanation:
Given
<em>Cylinder</em>
Radius = 3 inches
Height = 7 inches
<em>Sphere</em>
Radius = 3 inches
Required
The difference in the amount of wax needed to make a candle from each of these molds
The quantity or amount required to make a wax of candle from each molds can be calculated by getting the volume of both molds
The volume of a cylinder is calculated using
<em>V₁ = πr²h</em>
where r and h are the radius and the height of the cylinder, respectively.
r = 3 in and h = 7 in
The volume of a sphere is calculated using

where r is the radius of the sphere
r = 3 in
Calculating V₁
V₁ = πr²h
V₁ = π * 3² * 7
V₁ = π * 9 * 7
V₁ = π * 63
V₁ = 63π
Calculating V₂




V₂ = 36π
Having calculated the volume of each molds, the difference in the amount of wax needed can then be calculated.
Difference = V₁ - V₂
Substituting 63π for V₁ and 36π for V₂
Difference = 63π - 36π
Difference = 27π
<em>(Taking π = 3.14)</em>
Difference = 27 * 3.14
Difference = 84.78
Hence, difference in the amount of wax needed is 84.78 in³
