The factory normally produces 800 reels a day.
They have to cut their production by 1/5, however.
800 * 4/5 = 640 reels a day.
30 days would mean 640 * 30 reels...19200 reels.
This is less than 20,000, so the factory will NOT be able to produce enough reels.
<span>Whats is the sum (2/5x + 5/8) + (1/5x - 1/4)?
A.3/5x + 1/8
B.3/5x + 3/8
C.3/5x + 5/8
D.3/5x + 7/8
The answer is </span><span>B.) 3/5x + 3/8</span>
Hello from MrBillDoesMath!
Answer: The cylinder on the left has 4 times the volume of the cylinder on the right.
Discussion.
The volume of a cylinder of height "h" and radius "r" is given by
PI * r^2 * h (r^2 signifies r squared)
(Think of this formula as the area of the circle or radius r multiplied by the height the circle is pushed "up" to create the cylinder)
The volume of the cylinder on the left is: Pi * 4^2 * h = 16 Pi *h
The volume of the cylinder on the right is: Pi * 2^2 * h = 4 Pi *h
As 16/4 = 4, the cylinder on the left has 4 times the volume of the one on the right.
Thank you,

Logbx+logby-logbz
=logb(x*y)/z if b is the base of log.
There are two properties that you can apply to get the correct answer.
logb(x*y)=logbx+logby if b is the base of log.
logb(x/y)=logbx-logby if b is the base of log, so the correct answer for logbx+logby-logbz=logb(x*y)/z. Hope it help!
