Answer:

1/4 for both

Step-by-step explanation:

2/8 -- you divide 2 by 2 you get 1, 8 divided by 2 is 4 -- 1/4

3/12 -- you divide 3 by 3 you get 1, 12 divided by 3 is 4 -- 1/4

What is the rate of change of the water level , in feet per hour

miskamm [114]

A; rate of change is the same as slope, so, using the slope formula, $m= \frac{y_{2} - y\1_{1} }{ x_{2} - x_{1} }$ , where $m$ is the slope and $x_{1}$ , $x_{2}$ , $y_{1}$ , and $y_{2}$ are the $x$ and $y$ values.

Plug in $2$ points for $x$ and $y$ , water level being the $y$ and time being the $x$ since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.

$m= \frac{ 30-50}{4-0}$
$m= \frac{-20}{4}$
$m= \frac{-5}{1}$
$m= -5$ ft/hr
