Answer:
28
Step-by-step explanation:
Plug in the corresponding numbers to the corresponding variables. Note that:
m = 7
r = 8
t = 2
mr/t = (7 * 8)/2
(7 * (8/2)) = 7 * 4 = 28
28 is your answer.

You have two sets of parallel sides. A square has two sets of parallel sides, and it has the extra condition that all of the angles are right angles. So a square is definitely going to be a rhombus. Now, all rhombuses have four sides.
Step-by-step explanation:
From the given, we expressed the time that each of the team members ran in mathematical expression.
Reggie = 57.12 seconds
Alvin = 57.12 + 2.45 seconds = 59.57 seconds
Jose = 57.12 - 3.81 seconds = 53.31 seconds
We then sum up all the time we calculate to determine the total time for the team. The answer is therefore 170 seconds.
