Answer:
what's the graph because you have no image
$227.50. First, you convert 30% into a decimal: 0.30. Then, you multiply 325.00 by 0.30. This equals 97.50. 97.50 is 30% of 325, so you need to subtract 97.50 from 325.00. This equals $227.50.
Answer:
Height = 8 cm
Step-by-step explanation:
Volume of cylinder = π×r²×h
288π = π × 36 × h
(Divide both sides by π)
288 = 36 × h
(Divide 288 by 36)
8 = h
Answer:
The minimum cost is $17.30c
Step-by-step explanation:
Given
--- Volume
--- cost of wall paint
---cost of ceiling paint
Required
Minimum cost of paint
The volume is calculated as:
Substitute 288 for V
Make z the subject
The surface area is calculated as:
Because xy represent the dimension of the ceiling and the opposite of the ceiling (the floor) will not be painted. Hence, it does not require a coefficient of 2
The cost is:
Substitute
Differentiate w.r.t x and y
By comparison: 
Set them equal to 0
Substitute x for y
Cross multiply
Take the cube root of both sides
![x = \sqrt[3]{216}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B216%7D)
Substitute 6 for x and for y in

Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Estimated number of voters in favor of additional restriction = 43%
Margin of Error = ±4%
Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:
Minimum percentage of voters = 4% lesser than the estimated number of voters
Maximum percentage of voters = 4% greater than the estimated number of voters
Let number of voters = v
|v - 43%| = ±4%
v = - 4% + 43% = 39% = minimum percentage
v = +4% + 43% = 47% = maximum percentage
39% ≤ v ≤ 47%
