When painting my bedroom I used 3 1/2 liters of blue paint and 2 1/4 liters of red paint. How much paint did I use in all

Lubov Fominskaja [6]

Hi there!

To solve this problem, we need to find the total amount of paint used by adding the two fractions.

First, we need to find the common denominators below adding.

1/2 = 2/4
1/4 = 1/4

The common denominator is 4.

Now, we add the mixed numbers together:

3 2/4 + 2 1/4 = 5 3/4

Since 5 3/4 can't be simplified, the answer is:

5 3/4 liters of paint

Hope this helps!

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
