7/-6 or -7/6
Answer:
Step-by-step explanation:
area of base = π4² = 16π in²
lateral area = 2πrh = 2π·4·6 = 48π in²
surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²
Given:
After driving for 20 minutes, Juan was 62 miles away from his apartment.
After driving for 32 minutes Juan was only 38 miles away.
The time driving and the distance away from his apartment form a linear relationship.
To find:
The independent and dependent variables.
Solution:
If the value of a variable depends on the another, then it is called dependent variables.
If the value of a variable does not depend on the another, then it is called independent variables.
In the given problem, the distance of Juan from his apartment depends on the time he drove. So,
Dependent variable = Distance of Juan from his apartment in miles.
Independent variable = Time he drove
