Answer:
120 marbles
Step-by-step explanation:
we can find the answer by dividing the volume of the cylinder by the volume of the marble.
V of a cylinder is
pi×r^2×h = 1280pi
V of marble is
4/3 × pi × r^3
V is 32/3 pi
so final answer is 1280pi ÷ (32/3 × pi)
ANSWER IS 120 MARBLES

Answer:
8/3 < 8/2
D
Step-by-step explanation:
8/3 = 2.67
8/2 = 4
So, when fractions have equivalent (same) numerators, the one with the lesser denominator is the greater fraction.
There is more left if 8 is divided by 2 than when it is divided by 3

Evaluate the expression when b=16 and c=9.
c? +3(6-c)?
Answer:
0
Step-by-step explanation:
Since B = 16 and C = 9 we can plug into the equation.
(9) + 3 (6 - 9)
Since order of operations we subtract 9 from 6
6 - 9 = -3
Now we do -3 x 3 = -9
Now add -9 to 9
-9 + 9 = 0
Answer:
Step-by-step explanation:
3(6 - 9)
3(-3)= -9
9 + (-9) = 0

Answer:
45°
Step-by-step explanation:
A triangle in total is 180 degrees, add the 48 and 87 to get 135, subtract that from the total 180 to get your answer, 45 degrees.
Hope this helps!
Answer:
45
Step-by-step explanation:
♤interior angles of a triangle add up to 180♤
let angle V= x

If 55% of a number is 132 and 25% of the same number is 60, find 80% of that number.
Answer:
192
Step-by-step explanation:
It is always wise to look carefully at the question to see what information is given, and what information you are asked for. You are given two different fractions of the same number, and you want the value of a third fraction of that number. That third fraction is the sum of the other two.
__
The value of 80% of the number will be the sum of 55% and 25% of the number.
n×80% = n×55% +n×25%
n×80% = 132 +60
n×80% = 192
80% of the number is 192.
_____
Additional comment
Your first clue that there may be something special about this problem lies in the fact that one fraction of a number is all you need in order to find any other fraction. Here, we're given two fractions (55% and 25%), so that is more information than we need. Why? Because it simplifies the problem to one of addition. No proportions need to be solved.
__
If you were interested, you could determine 100% of the number to be ...
132/n = 55/100 ⇒ n = 132(100/55) = 240
or
60/n = 25/100 ⇒ n = 60(100/25) = 240
Then ...
0.80n = 0.80(240) = 192 . . . . 80% of the number
Or, you could write proportions for the 80% value:
80%/55% = n/132 ⇒ n = 132(80/55) = 192 . . . . 80% of the number
80%/25% = n/60 ⇒ n = 60(80/25) = 192 . . . . 80% of the number

given triangle, ABC is congruent to triangle EDC find A
Answer:
m<A = 30 degrees.
Step-by-step explanation:
m < C in triangle ABC = m < C in EDC so
x + 13 + 42 + x + 13 = 180
2x = 180 - 13 - 13 - 42
2x = 112
x = 56.
So m < C = 56+13 = 69.
m < B = m < D = 81
M < A = 180 - 69 - 81
= 180 - 150 = 30.
