Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96
Answer:
N/A
Step-by-step explanation:
Well find all of your important numbers or info and box them then take that info and use what your teacher has taught you
Answer:
w = 103
x = 77
y = 42
z = 138
These should be the answers
Answer:
4%
Step-by-step explanation:
First, we turn this into a fraction:
3/75 = 1/25 = 4%
So 3 is 4% of 75
We need the height of the cone
what we do is we know that when height is 10, V=something, so solve for the diameter is at that point and compare it to 24, the full height
sorry if confusing
V=(1/3)hpir^2
when h=10
160pi/3=1/3(10)pir^2
ties 3 both sides
160pi=10pir^2
divide by 10pi
16=r^2
sqrt both sides
r=4
at that point, the radius is 4
the real radius of the ful is 24/2=12
4/12=1/3
it is 1/3 full
if 1/3=160pi/3cm
2/3=320pi/3cm^3
needs 320pi/3 cm^3
