DeAndre downloaded 8 apps onto his tablet in 12 seconds. At this rate, how many apps could he download in one minute? (12 seconds = 1/5 minute )

40 apps

Explanation:

Because 12 seconds is 1/5 of a minute,

12 x 5 = 1 minute

Since he downloads 8 apps every 12 seconds,

8 x 5 = 40 apps per minute

Hope this helps :)

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
