Answer:
1. yes
2.1,406
Step-by-step explanation:
The answer for this answer would be A
65,130 that should be the answer...
You will need 2 equations, since there are 2 variables (hours worked by George and the ones of Dorothy), let's say x and y respectively
We know
x+y=48 (since they work 48 hours together) and
12x+11.25y=555 (since the sum of their respective hours multiplied by their salary gives a total of 555$)
To solve that, you can isolate either one of the variables and replace it in the second formula, for example:
x+y=48, therefore x=(48-y)
<span>Substitute x in 12x+11.25y=555 and solve for y (to find Dorothy's hours)
</span><span>12(48-y)+11.25y=555
</span>576-12y+11.25y=555
21=0.75y
y=28
A) 1104/ 138 = 8
B) 1st = 30/2 = 15, 2nd = 15/2 = 7.5, 3rd = 7.5/2 = 3.75, 4th 3.75/2 = 1.875, 5th = 1.875/2 = 0.9375, 6th = 0.9375/2 = 0.46875, 7th = 0.46875/2 = 0.234375, 8th = 0.234375/2 = 0.117 = 0.12
Answer is B
