Answer:
The answer is B. $3.85.
Step-by-step explanation:
This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.
Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.
This is why the answer is B. $3.85.
The volume of the larger cube is 227 inches cube.
<h3 /><h3 /><h3>Volume of a cube is describe below:</h3>
where
L = length
The small cube has the following volume:
Let
The side length of the small cube = x
Therefore,
95 = x³
x = ∛95
x = 4.56290264
x ≈ 4.6
Its side length is 1.5 inches less than a second larger cube. Therefore,
- length of larger length cube = (x + 1.5 )inches = 4.6 + 1.5 = 6.1 inches
Therefore, the volume of the larger cube can be found as follows:
Volume = 6.1³
volume = 226.981
volume ≈ 227 inches³

Answer:
20cm
Step-by-step explanation:
Given data
Area= 80cm^2
we know that the expression for the area of a triangle is
A= 1/2B*H
from the given expression 1/2(8h) =80 the base is 8cm
let us substitute to find the height h
1/2(8h) =80
4h=80
h= 80/4
h= 20cm
Hence the heigth h is 20cm
