Stan, a local delivery driver, is paid $3.50 per mile driven pus a daily amount of $75. On Monday, he is assigned a route that i

Alex Ar [27]

To find out how much Stan is paid a day, simply find out how many miles Stan drives per day, and multiply that with the amount Stan is paid per mile (in this case $3.50 per mile). Then, add that with the daily amount Stan earned (which is $75).

For example, on Monday, Stan drove a total of 30 miles (and he's paid $3.50 per mile).

Simply multiply $3.50 (per mile) with 30 (total number of miles driven), and that should equate to $105 earned for driving a total of 30 miles.

Then, add $105 (earned from driving 30 miles) to $75 (daily pay) and that equals $180.

Stan had been paid a total of $180 on Monday.

HACTEHA [7]

Answer:

m = $\frac{6}{5}$ , n = $\sqrt{2}$

Step-by-step explanation:

m has to be a rational number but it can't be an integer.

$\frac{2}{3}$ is rational and it is not an integer, $\frac{6}{5}$ is rational and it is not an integer, 4π is not rational, and $\frac{6}{2}$ is rational but it is an integer because it's equal to 3.

m must equal $\frac{2}{3}$ or $\frac{6}{5}$ .

n has to be irrational.

$\sqrt{9}$ is not irrational because it is equal to 3, which is rational.

This leaves m = $\sqrt{2}$ .
