Answer:
=54.25 m^2
Step-by-step explanation:
We will assume the pool is a rectangle
A = l*w
A = (8.75) * (6.2)
=54.25 m^2
Answer:
SAS postulate , since an angles is equal in both triangles plus the diagonals are divided equally means that's equal in both of the triangles
Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.
Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20
Therefore, one person saved 20 and the other saved 20 + 15 = 35.
Number of people participating in the relay race = 4
Total distance ran by 4 people of a team = 400 yards
Let us assume the distance run by each member = x yards
Then
4x = 400
x = 400/4
x = 100 yards
Total time taken to rum the full distance = 53.2 seconds
Average running time of each person = 53.2/4
= 13.3 seconds.
