Dan and his mom went to the
supermarket. the total amount of
their purchase was $126.62. if
dan's mom hands the cashier
seven $20 bills, how much change
did his mom receive?

First, we must figure out how much money seven $20 bills are worth. We can multiply 20 by 7 and we will get a product of 140.

If Dan's mom gives the cashier $140, Dan's mom will receive change. We can find out how much change she is getting by subtracting 126.62 from 140.

$140 - $126.62 = $13.38

Therefore, Dan's mom will get $13.38 in change.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
