Answer:
average = 52, 100 on fourth test
Step-by-step explanation:
average = 75 + 74 + 71 = 156 / 3 = 52
average = 52
b grade = 75 + 74 + 71 + 100 = 320 / 4 = 80
to get a b grade she must get 100 on her fourth test
Volume of cone canbe calculated using the following rule:
volume of cone = (1/3) x pi x (radius)^2 x height
from the givens:
pi = 22/7
I'll assume that the 10 cm refers to the height
radius = 16/2 = 8 cm
substitute in the equation to get the volume as follows:
volume=(1/3) x (22/7) x (8x10^-2)^2 x (10x10^-2)
= 6.7 x 10^-4 m^3
Hi Lania!
If Koby can work 22 math problems in 30 minutes, then he can work 44 in an hour (multiply your problems completed and time elapsed by 2).
Now, we have to figure out how many he can complete in 3 hours, so all we have to do is multiply our current math problems by 3.
44 * 3 = 132
This means that Koby can complete D.) 132 math problems in 3 hours.
I hope this helps!
