We know that
[area of the painting]=13 in* 17 in-----> 221 in²
if a<span>n artist painting at
$0.30 per --------------> 1 in</span>²
x$--------------> 221 in²
X=221*0.30------> x=$66.30
the answer is
$66.30
Answer:
1/4
Step-by-step explanation:
The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: -5 = -5/1
Recall the angle sum identities:


Now,

Divide through numerator and denominator by
to get

Next, we use the fact that
lie in the first quadrant to determine that


So we then have


Finally,

Let x be the amount each friend pays
.
There are five friends contributing ,so
5x will be the total money collected
.
It needs to equal the price plus the tax, 210 + 15
= 225
So the equation becomes,

5x = 225
dividing right side by 5, we have
x = 225/5 = 45
Answer: So each frien pays $45.
