Hope this helps!
Answer:
It would be $62.62 because basically you want to do 52.50 times 1.25
F - 1.47
The largest box represents 100 small cubes or 1. The four pillars represent 10 and there is four of them so it is 40. Then, the individual cubes are 7. So, 1.47.
Answer:
592 hours
Step-by-step explanation:
Given


Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle

Let t represent the time take to cover 11000m²;
The relationship between these parameters is:

Substitute 3.14 for π

Divide both sides by 3.14



Take square root of both sides



Divide both sides by 0.10




<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
Answer:
the answer is -7 I have to subtract the last to numbers
