Answer:
Rob saved $30 while he earned $75.
Step-by-step explanation:
Given:
For every 15 dollars he earns babysitting, he saves 6 dollars.
For money earned = $15
Money saved = $6
We will first find the percentage amount saved by rob
Percentage of amount is calculated by dividing money saved with for money saved and then multiplied by 100.
Percentage amount saved = 
Now we need to find the amount of money save when money earned $75.
Amount of money saved can be calculate by multiplying money earned with percentile amount saved.
Framing in equation form we get;
Amount saved = 
Hence Rob saved $30 while he earned $75.
Answer:
A) A cylinder with a height of 2 and a diameter of 8.
Step-by-step explanation:
The height of the cylinder is half the radius. Therefore.
Height of the cylinder = (half of the radius)/2
Answer choice A) A cylinder with a height of 2 and a diameter of 8.
Note that a diameter is found using the following formula:
d (diameter) = 2r (radius).
First, divide 2 from the diameter to find the radius:
8/2 = 4
Next, divide by 2 again to find the height of the cylinder:
4/2 = 2
In this case, the height of the cylinder is 2, ∴ the choice is correct.

Answer: Option B.
Step-by-step explanation:
When we have an interval with lower bound m and upper bound M, such that:
m ≤ x ≤ M
The mid-point is:
(m + M)/2
in this case, we have:
m = 22
M = 27
then the mid-point is:
(22 + 27)/2 = 24.5
and we know that f = 7, then:
f*x = f times the mid-point = 7*24.5 = 171.5
The correct option is B.
the answer is 32.35% that is the rate
