Answer:
528
Step-by-step explanation:
Question: 16 + 
* 2 ÷ 16
Work:
= 64
2/16 = 0.125
64/0.125 = 512
512 + 16 = 528
Answer:
All you have to do is multiply 5000 by .025 to find that she earns $125. Next, you multiply 125 by 7 and find that she earns $875!

Answer:
5/9
Step-by-step explanation:
complement means not choosing an orange
P( not choosing orange) = (apple and fruit) / total
= (4+6) / (4+6+8)
=10/18
= 5/9
The answer is 90%. You get this answer by multiplying both the numerator and denominator by 5 so 18x5=90 and 20x5=100 giving you a fraction of 90/100 and a percentage of 90%.
Problem One
Call the radius of the second can = r
Call the height of the second can = h
Then the radius of the first can = 1/3 r
The height of the first can = 3*h
A1 / A2 = (2*pi*(1/3r)*(3h)] / [2*pi * r * h]
Here's what will cancel. The twos on the right will cancel. The 3 and 1/3 will multiply to one. The 2 r's will cancel. The h's will cancel. Finally, the pis will cancel
Result A1 / A2 = 1/1
The labels will be shaped differently, but they will occupy the same area.
Problem Two
It seems like the writer of the problem put some lids on the new solid that were not implied by the question.
If I understand the problem correctly, looking at it from the top you are sweeping out a circle for the lid on top and bottom, plus the center core of the cylinder.
One lid would be pi r^2 = pi w^2 and so 2 of them would be 2 pi w^2
The region between the lids would be 2 pi r h for the surface area which is 2pi w h
Put the 2 regions together and you get
Area = 2 pi w^2 + 2 pi w h
