Step-by-step explanation:
Molly ran 1/4 of a mile in 1 minute, i.e.
1/4 mile : 1 minute
Multiply both sides by 4 to get time for one mile
1 mile : 4 minutes
Multiply by 4 again to get time for 4 miles
4 miles = 4*4 = 16 minutes.
So it takes Molly 16 minutes to run four miles.

Step-by-step explanation:
1. x^2 + 10x + 25
2. x^2 - 25
.........
Answer:
<u><em>She got 18 correct</em></u>
How to do this:
25 x 25 = 6.25 if she got it correct
20 x 25 = 5.00 - 10 - 10 -10 -10 -10 = 4.50
18 x 25 = 4.50 - 10 -10 -10 -10 -10 -10-10 = 3.80
Answer:
10,000 cm² in 1 m²
1,000,000 cm³ in 1 m³
Step-by-step explanation:
There are 100 cm in 1 m
Therefore, to find how many square cms are in 1 square meter, we need to square 100: 100² = 100 x 100 = 10,000
Therefore, there are 10,000 cm² in 1 m²
Therefore, to find how many cubic cms are in 1 square meter, we need to cube 100: 100³ = 100 x 100 x 100 = 1,000,000
Therefore, there are 1,000,000 cm³ in 1 m³
