two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 100 miles per hour. The westbound train travels at 80 miles per hour. How long will it take for the two trains to be 252 miles apart? Do not do any rounding.

1.4 hours

Step-by-step explanation:

you can write a system of equations to find the answer.

80t + 100t = 252

plug it into desmos to find the true value.

it is 1.4

the trains will be 252 miles apart after 1.4 hours.

if this helped, be sure to mark as brainliest :)

answer: 25 is the correct answer

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
