it looks like it is completely factored out to me at least there is a high possibility I am wrong because that looks complicated I wish I could help
Answer:37 and half hrs
Step-by-step explanation:
This is what I get
Myra: 50/2= 25 bulbs/hr.
Francis: 45/3= 15 bulbs/ hr
25+15= 40/hr. Together per hr
Need to find 150 bulbs how many hrs
40/1=150/t
40t=150
T= 150/4
T= 37.5
37hrs and 1/2
Answer:
$25
Step-by-step explanation:
500 mins = $35 (fixed + per minute charge)
1500 mins = $55 (fixed + per minute charge)
If we let per minute charge be "m"
and
let fixed charge be "f"
we can write 2 equations as:
35 = 500m + f
and
55 = 1500m + f
Now,
We re-write both equations in terms of f and equate both expressions:
f = 35 - 500m
and
f = 55 - 1500m
Equating:
35 - 500m = 55 - 1500m
-500m + 1500m = 55 - 35
1000m = 20
m = 20/1000
m = 0.02
Now we find f, what we are looking for:
f = 35 - 500m
f = 35 - 500(0.02)
f = 25
So, the fixed charge is $25
Answer:
mean = 0.76
median = 0.75
range = 1.79
Step-by-step explanation:
mean = sum/no of items
for media they need to be sorted: 0.05,0.06,0.75,1.10,1.84
median is the middle item, so 0.75
range = largest item - smallest item = 1.84 - 0.05 = 1.79
