Robert plays cricket. He hit the ball in such a way that it goes up 180 feet

PilotLPTM [1.2K]

Answer:

4 feet per second

Step-by-step explanation:

Hi there!

$v=D/t$ where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

$v=180/45\\v=4$

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!

Troy shares a family bag of 24 Jet Plane

nlexa [21]

Answer:

Troy ate 7 lollies.

Step-by-step explanation:

You start out by finding how many lollies Troy's two friends ate out of the 24 lollies. To find out how much Tane ate out of the 24 Jet Plane lollies you simply divide 24 by the denominator --> 24/3=8, then you multiply your answer by the numerator --> 8x1=8, so Tane ate 8 of the 24 lollies. Repeat this same process for Levi, and your answer should be 9.

Because Tane ate 8 out of the 24 lollies and Levi ate 9 out of the 24 lollies, that indicates that 17 out of the 24 lollies are gone (just add your results, 8+9=17). This leaves Troy with only 7 lollies (subtract 17 from 24 to find out how many lollies are left, 24-17=7).
