A moving truck is equipped with a ramp that extends from the back of the truck to the
ground. When the ramp is fully extended, it
touches the ground 12 feet from the back of the
truck. The height of the ramp is 2.5 feet.
Calculate the measure of the angle formed by
the ramp and the ground.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

add 8+12 to get a simplified answer of 12r-20
