2(-3n-5)-5(4n-8)
(-6n-10)+(-20n+40)
-26n-30
You set up a proportion. first, put the percent so if it's 30 percent, it would be 30 over 100. Then, set up the second part. is over of.
C=2πr
The C stands for circumference
the π is Pi (3.14)
and r is the radius (length of half a circle)
Since the sides are 10 ft you multiply that by 2 to get the length of both sides which gives you 20 feet.
Then to find the circle, since both are half circles. You can just do the normal circumference equation and you will end up with the same answer.
For example in this problem: this problem gives you the diameter but you need the radius of the circle. C=2(π)(1.5)
C=9.42 < this is the circumference of the circle.
Then you add the sides of the table which are 20 feet.
So the final answer is 29.42 feet.
Answer:
14
Step-by-step explanation:
8x175%= 14
Answer:
The percent markup is, 
60.89 % .
Step-by-step explanation:
A pair of shoes cost $ 22.99 to make, the local store sells them for $ 36.99.
So, the increased value for each pair of shoes,
= $ (36.99 - 22.99)
=$ 14
So, the percent markup is,
%
60.89 %
