May someone check my work? Jeff and his cousin work during the summer for a roofing company. Jeff's cousin has been working for the company longer, so his pay is 40% more than Jeff's. Last week his cousin worked 30 hours, and Jeff worked 25 hours. Together, they earned $562.80. What is Jeff's hourly pay? Explain or show your reasoning for full credit.

30j+40% + 25j= 562.8

30j+25j= 55j

55j + 40% = 562.8

40% of 55 is 22

77j = 562.8

562.8 77 = 7.309090909

Simplify 7.309090909

$7.31 Per hour.

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
