What is the unit rate of $1.12 for 8.2 ounces?

pashok25 [27]

That is around 13 or 14 cents. The specific answer is 13.65853659 cents, but you can either round up to 14 or round down to 13 (rounding up to 14 is the correct way to do it.)

First you divide 1.12 by 8.2 to get the unit rate because It takes $1.12 to buy 8.2 ounces. 1.12/8.2=13.65853659

Hope this helped!

Hello there, <br><br> can someone please help me with this question

Answer:

10 sides.

Step-by-step explanation:

Two same interior angles + 72 degrees = 360.

Thus, the interior angle of the polygon is $\frac{360-72}{2} =144$ .

The formula to find the interior angle of a polygon is $\frac{180(n-2)}{n}$

$\frac{180(n-2)}{n} =144$

Multiply both sides by n:

$\frac{180\left(n-2\right)}{n}n=144n$

$180\left(n-2\right)=144n$

Expand:

$180n-360=144n$

Add 360 to both sides:

$180n-360+360=144n+360$

$180n=144n+360$

Subtract 144n from both sides:

$180n-144n=144n+360-144n$

$36n=360$

Divide both sides by 36:

$\frac{36n}{36}=\frac{360}{36}$

$n=10$
