Question

s = - 4, and t = - 6.

1. $\frac{s + t}{5}$
2. find the quotient of - 65 and - 13.

the boiling - point of water is affected by changes in elevation.
use the formula t = 212 - 0.0018a, where a represents the altitude in feet, to find the boiling point of water at an altitude of 3000 feet. then explain its meaning.
find the average rate of change in altitude over time for several hot air balloons. find the rate of change in feet per minute for each balloon.
time (min) | rate of change (ft/min)
135
30
60

Explanation:

Step1: Calculate 32.

Given $s = - 4,t=-6$, first find $s + t$.
$s + t=-4+( - 6)=-10$.
Then $\frac{s + t}{5}=\frac{-10}{5}=-2$.

Step2: Calculate 34.

The quotient of -65 and -13 is $\frac{-65}{-13}=5$.

Answer:

1. -2
2. 5
