Hope this helps!
1) we have to calculate the lenght of the baseball field.
perimeter of the baseball field=2(radius)+lenght of a semicircle.
2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)
Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,
2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.
10 ft------------------------1 second
789,82 ft----------------- x
x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s
answer: 79 seconds.
Answer:
Step-by-step explanation:
The system would be:
And I attached the graph. The system will have 2 solution (The 2 intercepts between the curves)
How fast did he run each mile, that is to say how fast did he run 1 mile.
We can simply find the time it took him to run 1 mile.
He ran 7 miles in 57 3/4 minutes = 57.75 minutes.
In 1 mile he would run = 57.75/7 minutes = 8.25 minutes.
He ran 1 mile, that is each mile in 8.25 minutes.
I hope this helped.
