So, if theirs 8 players and the ball was passed 24 times that means the ball went around the circle 3 times. If the radius (half of the diameter) is 9yd that means u have to find the circumference of the circle with you use the equation c=2(3.14)r so the r is radius so you do 2 times pi or 3.14 to get 6.28 then multiply that by the radius so in this case times 9 to get 56.52. Then when u round that to the nearest tenth u get 56.5. So he ran 56.5yd

A.) 75 x 60 = 4500 in an hour
4500 x 24 = 108000 in a day
108000 x 365 = 39420000 in a year
39420000 x 45 = 1,773,900,000 in 45 years
B.)2200800 / 75 = 29344 mins
29344 / 60 = 489.066666667 hours
489.066666667 / 24 = 20.37777778
you get it

Solve for c in the scientific formula C=Wtc/1000

Troyanec [42]

C = Wtc/1000

1000C = Wtc

Wtc = 1000C

W = (1000C) / (tc)

This is assuming that C and c are not the same.

If they are the same, we have:

W = (1000) / t, provided ,that C and c are not equal to 0.

-5x+7+2x-13<9 Please Explain

olganol [36]

Ok the answer is -5 less than 9 which is true lol

Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it

-3x-6 < 9
+6< +6

-3x < 15

Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)
