y=3
x=3
Answer:
5 + 2q = 15
Step-by-step explanation:
The perimeter is 4 + 2 + q + (q - 1) = 15.
Add 4 + 2 then subtract the sum from both sides.
q + (q - 1) = 9
This can be simplified further by adding the "q" variables together.
2q - 1 = 9
Add 1 to both sides.
2q = 10
Divide both sides by 2 to isolate q.
q = 5
Tom--------------
>10 sq ft per minute
Tim-------------------
>3.5*10=35 sq ft per minute
Both painters (10+35)=45
sq ft per minute
let's assume a cubic unit crate----------> V1=1*1*1=1 feet3
<span>the total surface of the cube is S1=6*(1*1)=6 </span>sq
ft
if the volume of the cube increases twice
V2=2 feet3 ------------------- > 2=x*x*x------------- >x=2^(1/3)
And the S2=6*(2^(1/3)*<span> 2</span>^(1/3)=9.5244 sq ft
V2/V1=9.5244/6=1.5874
Therefore
If Tim and Tom-----------------------
> take 1 day----------- > to paint a crate V1
For the crate V2------------- > take 1.5874 days
assuming an 8-hour work day
0.5874*8=4.70 hr-------------- > 4 h 42 min
The answer is 1 day 4h 42 min
