Answer:
Part a) The equation is 
Part b) 
Step-by-step explanation:
Let
p -----> the number of paintings
we know that
Break even is when sales are equal to cost.
The linear equation that represent this problem is
Solve for p
Subtract p both sides
Divide by 7 both sides
Rewrite
Check the solution
substitute the value of p
----> is ok
You just need to solve for g, multiply it out to get -g+6+2g=-4g-4, subtract 6 from both sides to get -g+2g=-4g-10, then add 4g to both sides for -g+2g-4g=-10, then add the g's together to get -3g=-10, divide both sides by -3 and you get g=3,1,3 (three and one third).
Answer: hundredths
Step-by-step explanation:
The second number past the decimal point is the hundredths place
Answer:
Below in bold.
Step-by-step explanation:
a. SA = 2π r^2 + 2πrh
2πrh = SA - 2π r^2
h = (SA - 2πr^2)/2πr
When π = 3.14 we have
h = (SA - 6.28r^2)/ 6.28r
b. SA = 6.28*1.5^2 + 6.28*1.5* 5
= 61.23 in^2
