Answer:
The answer to your question is: 20 hours.
Step-by-step explanation:
Data
Hortencia = $350
Alex $18 / h
# hours Alex must paint to make more money than Hortencia = ?
Process
Equation 18 x n > 350
n > 350 / 18
n > 19.4 hours
If Alex work 19.4 hours, he will make the same amount of money than Hortencia, then He needs to work 20 hours.
Angle measure of triangle
= 180 degrees
X = 180- 75 - 50 = 180 - 120 = 60
Ans= 60 degrees

<span>Answer:
17576=pir^2h
the amount of material M=2pir^2 +2pirh
M=2pir^2+2pir(17576/pir^2)
DrM= 4pir- 35152/r^2
DrM=0
0=4pir- 35152/r^2
r=(13*2^(2/3))/pi^(1/3)
17576=pi((13*2^(2/3))/pi^(1/3))^2)h
17576/(pi((13*2^(2/3))/pi^(1/3))^2))=h
r=14.0901
h=28.1801
M=3742.21 cm^2</span>
