A) 6
The cube root of 216 is 6. 6 x 6 x 6, or 6^3 = 216.
Answer: He can mow 4 lawns before he needs to buy more gasoline.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Gallons of gasoline available: 2/3
</em>
- <em>Gallons of gasoline used for mow a lawn: 1/6
</em>
So, to find the number of lawn that he can mow, we have to divide the gasoline available (2/3) by the amount used for mow a single lawn (1/6)
Mathematically speaking:
2/3 ÷1/6 = (2x6) / (3x1) = 12/3=4
He can mow 4 lawns before he needs to buy more gasoline.
Answer:
Jeremy swims 4/5 of a kilometer each day.
Step-by-step explanation:
Since 5 3/5 can be turned into 28/5, then divided by 7/1, you will get 4/5. So Jeremy swims 4/5 of a kilometer each day.
Eli got his answer by multipying 5 3/5 by 7 which was an incorrect process.

Step-by-step explanation:
So, the track is composed of a rectangle and two semicircles.
The side length of the rectangle is x, and the radius of the semicircles is r.
Part A)
The perimeter is simply the length around the figure.
We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.
Factored it would be (2x + 3)(5x - 9)
