Answer:
a. 311 hours
b. i. $3,100 in receipts
ii. $2,799 in expenses.
Step-by-step explanation:
a. The company is making $10 per hour and spending $9 an hour. Their profit is therefore:
= 10 - 9
= $1 per hour
Since they spent $311 on the new equipment, the amount of time it would take for them to make this back is:
= 311 / 1
= 311 hours
b. In 311 hours, the total receipts would be:
= 311 * 10
= $3,110
The expenses would be:
= 311 * 9
= $2,799
I believe it’s 72 I hope it’s right
Answer:
Step-by-step explanation:
Having the radius to be involved, the shape is a circle.
<u>Circumference formula </u>
Finding radius, formula will be reversed.
Let
x-----> the number of hours that Candice spent doing her homework
y-----> the number of hours that Ronald spent doing his homework
we know that
convert mixed number to an improper fraction
so
-------> equation A
------> equation B
Substitute equation A in equation B
convert an improper fraction to a mixed number
therefore
<u>the answer is the option B</u>
The idea of the Cavalieri's Principle states that even if the cylinder is oblique, so long as the planes in the figure are parallel, the equation would still be equal to,
V = Bh = πr²h
Substituting,
2,500 = π(10 m)²h
h = 7.95 m
The answer should be 5 meters.
