A circle is 360 degrees, and there are 12 sections on a clock. Divide 360 by 12, which will get you 30. The hand moves 4 hours, so you would multiply 30 times 4 and get 120 degrees. I hope I helped!

Answer:
Approximately 3.8 seconds
Step-by-step explanation:
H(x)=-16x^2+60x+4
We want to find when the ball hits the ground, or where the zeros are
0 =-16x^2+60x+4
Using the quadratic formula
-b ±sqrt(b^2 -4ac)
---------------------------
2a
-60 ±sqrt(60^2 -4*-16*4)
---------------------------
2(-16)
-60 ±sqrt(3600+256)
---------------------------
-32
-60 ±sqrt(3856)
---------------------------
-32
We want the positive value for time
-60-62.09669879
---------------------------
-32
3.815521837
Approximately 3.8 seconds
Answer:
it would cost 35 each I think
3* 3.14
= 9.42
9.42 * 2
= 18.84
* (4+3)
= 131.88 cm.
Glad to help! :D
