Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²
Answer:
The total number of halves is 4 and the lines are considered as 1/4, 1/2 and 3/4.

Answer:
50%
Step-by-step explanation:
Because 30 is half of 60. And 50% is half of 100% so both 30 and 50% are equivalent in this problem
Answer: 23.20 dollars
Cost for 1 shirt = $14.63
Cost for 1 visor = $8.57
Total = 14.63+8.57 = 23.20
==============================================================
Explanation:
s = cost of 1 shirt
v = cost of 1 visor
costs are in dollars
There are 43 players and 2 coaches that get a shirt. There are 43+2 = 45 people total that get a shirt. The amount of money spent on all the shirts is 45s because we multiply the number of people (45) with the cost per shirt (which is s). Set this equal to 658.35 and solve for s
45s = 658.35
s = 658.35/45
s = 14.63
Each shirt costs $14.63, and this is the amount each player should pay.
-------------------
Kenny is also ordering 43 visors. The total cost here is 368.51 dollars. This means the equation we need to solve is 43v = 368.51
Divide both sides by 43 to isolate v
43v = 368.51
v = 368.51/43
v = 8.57
Each visor costs $8.57, and this is the amount each player should pay.
-------------------
Add up the two costs we found and we get 14.63+8.57 = 23.20, which is the total cost each player must pay for both a shirt and a visor.
