i am pretty sure the answer is 8.
Answer:
2,360.95
Step-by-step explanation:
I got it right :)
Let same number of hours = x,
since the salary earned is also the same, then
Salary of supervisor A = $25x
Salary of supervisor B = $20(30)+$30(x-30)
Equating
25x=600+30(x-30)
30x-25x=900-600
5x=300
x=60 hours
Check:
Salary of supervisor A = 25*60=1500
Salary of supervisor B = 20*30+30*(60-30)=600+900=1500, ok.
The model we'll use is b. 5/3 = 40/w
The mass of the shorter bar is 24 kg.
To solve for the problem, using the formula above, it will looks like this
5/3 = 40/w -- cross multiply
(5)(w) = (40)(3)
5w = 120 -- isolate the w
5w/5 = 120/5
w= 24
