Ratios compare 2 or more values, as well as rates.
Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D

Answer:
41.86 miles each hour
Step-by-step explanation:
Kelli and her family went to the beach for a vacation. They drove 293 miles in 7 hours to get there. ABOUT how many miles did they drive each hour?
This Question is calculated as:
7 hours = 293 miles
1 hour = x miles
Cross Multiply
7 hours × x = 1 × 293 miles
x = 293 miles/7 hours
x = 41.857142857 miles per hour
x ≈ 41.86 miles per hour
Hence, they drove 41.86 miles each hour
