Answer:
FJ = 24
DM = 16
EM = 18
Step-by-step explanation:
I remember that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side. Therefore the median is split into two parts where one side is always twice as long as the other. So given that segment ML is 8, the other part of the segment (DM) must be 16 as 16 is 2/3 of 24 and 8 is 1/3 of 24 and 1/3 + 2/3 = 1.
Therefore, since MJ is 8, FM must be twice as long so it is 16. Add them up to get FJ, and 8 + 16 is 24.
Finally for EM, since the longer part of the median is twice the length of the smaller part EM must be 18 since 9 × 2 = 18, and 2/3 of 18 is 27, 9 + 18 = 27.

Answer:
Perimeter: 132
Area: 864
Step-by-step explanation:
Perimeter:
Add all the sides, so 30 + 18 + 8 + 18 + 18 + 18 + 4 + 18 = 132
Area:
Split it into two separate rectangles, so the first one would be 18 * 30 = 540. The second one would be 18 * 18 = 324. Then, add 540 + 324 = 864

Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
