Answer:
62.5% of the parking spaces are taken.
Step-by-step explanation:
Given
To determine
What percent of the parking spaces are taken?
The percentage of taken spaces of the part can be determined using the formula
% of Taken spaces = [Taken spaces / Total Spaces ] × 100
= [1875 / 3000] × 100
= 0.625 × 100
= 62.5%
Therefore, 62.5% of the parking spaces are taken.
First you subtract 15 from 26 and get 11.
Second you multiply 11 by 2 and get 22.
Therefore your answer is 22.
Answer:
Below in bold.
Step-by-step explanation:
The surface area of the box
= x^2 + 4hx where x = a side of the square base and h is the height.
So x^2 + 4hx = 8
The volume of the box
V = x^2h
From the first equation we solve for h
4hx = 8 - x^2
h = (8 - x^2) / 4x
Now we substitute for h in the formula for the volume:
V = x^2 * (8 - x^2) / 4x
V = 8x^2 - x^4 / 4x
V = 2x - 0.25x^3
Finding the derivative:
V' = 2 - 0.75x^2 = 0 for max/mimn values
x^2 = 2/ 0.75 = 2.667
x = 1.633.
So the length and width of the base is 1.633 m and the height
= ( 8 - 2.667) / (4*1.633)
= 0.816 m
The maximum volume = 0.816 * 2.667 = 2.177 m^2.
The answers are correct to the nearest thousandth.
This can be answered using the following formula for interest:
Let:
F = future value
P = principal value
n = interest period (n = 3)
i = interest percentage
F = P(1 + i)^n
Substituting the given values, we arrive at the following:
F = 3300(1 + 0.04)^3
F = 3712.05
Therefore, after 3 years, the balance in the account will be $3712.05
