Answer:
ANSWER: The ratio of the heights of cylinders A and B is 1:9.
Step-by-step explanation:
The volume of cylinder A is %28pi%29%28%283r%29%5E2%29%28h%29+=+9%28pi%29%28r%5E2%29%28h%29.
So tripling the radius in cylinder A makes the volume 9 times the volume of cylinder B. If the volumes are to be the same, the height of cylinder A must be 1/9 the height of cylinder B.

Answer: angle U = 72 degrees</h3>
===================================================
Explanation:
If you have n sides of a polygon, then the interior angles add up to S = 180(n-2)
In this case, n = 5, so S = 180(n-2) = 180(5-2) = 540
We can add up the five angles the diagram shows and set that sum equal to 540 to solve for x
S+T+U+V+W = 540
90+2x+x+2x+90 = 540
5x+180 = 540
5x = 540-180
5x = 360
x = 360/5
x = 72
Since angle U = x, this means angle U = 72 degrees
Answer:
$4.50
Step-by-step explanation:
We can use the distributive property to solve this problem. 0.05(50+40) is the total sales tax. 0.05 being the percentage and 50 and 40 being the things we need to distribute 0.05 to. This becomes 2.5+2. This is 4.5.
