Answer:
Charles completed the quiz problems at the slowest rate
Step-by-step explanation:
we know that
To find out the unit rate divide the number of quiz problems by the time employed
1) Maya completed 15 quiz problems in 10 minutes
so
2) Andrew completed 12 quiz problems in 8 minutes
so
3) Charles completed 16 quiz problems in 16 minutes
so
Compare the unit rates
1 < 1.5
therefore
Charles completed the quiz problems at the slowest rate
We are told that Tristan is planting a garden that's square shaped and its area is 64 square meters. Because 8 * 8 = 64, we have a square where each side is 8 meters along.
From an algebra point of view, where s is a side of the square,
s² = 64
s = 8 or s = -8 by taking square roots of both sides
s = 8 by discarding the -8 (lengths cannot be negative)
Now that we know a square's side we need its perimeter. Each side is the same, so a square's perimeter is four times a side.
4 * 8 = 32, which is our perimeter.
Therefore 32m² of material are needed.
Answer:
The ratio is 2:30
