An elevator began at an elevation of 85.5 feet and ascended at a rate of 2.75 feet per second. What was the elevation of the elevator after 8 seconds?

107.5 feet

Step-by-step explanation:

2.75 x 8 = 22, 85.5 + 22 =  107.5 feet

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.

u also answered this so i think u would know but i am here to

put in or use mine

one set of data has more variation than the other. hope this !
