A simple method is to square all the answers

now arrange them
526.32
I would recommend using an inequality. 100/x=19/100 and solve from there.
Answer:
![t = wR_p [R_p = 1.05]](https://tex.z-dn.net/?f=t%20%3D%20wR_p%20%20%20%20%20%20%20%20%20%5BR_p%20%3D%201.05%5D)
Step-by-step explanation:
<em>For the case of victor: </em>, let total cost be
and total weight be
.
So the price rate per 1 pound of blueberries should be,

<em>For general case: </em>1 pound costs
so
pound costs
pounds. So the equation should be,
![t = wR_p [R_p = 1.05]](https://tex.z-dn.net/?f=t%20%3D%20wR_p%20%20%20%20%20%20%20%20%20%5BR_p%20%3D%201.05%5D)
Hmmm I think it may be the third?
To find the area of a regular figure,the formula would be:
s^2(n)/4tan (180/n)
where
s is the length of any side
n is the number of sides
In this case:
12^2(6)/4tan (180/6)
=144/4tan(30)
=144/120tan
≈374.1 in^2 (correct to the nearest tenth)
Hope it helps!
