Container A has radius ​r​ and height h . It holds a maximum of 44 ounces of water. Container B has radius 2.5r and height 4h .
Dennis_Churaev [7]
Set an equation:

\pi  r^{2} h=44
divide both sides by 3.14
r^{2} h=14

\pi  (2.5r)^{2} 4h=x
divide both sides by 6.25, 4, and 3.14
r^{2} h=x/78.5

Since these two equations are equal, we can set them up that way.

x/78.5=14
multiply both sides by 78.5
x=1099

Answer: The maximum amount of water that container B can hold is 1,099 ounces.

In a class of 10, there are 2 students who forgot their lunch. If the teacher chooses 2 students, what is the probability that b
Anuta_ua [19.1K]

At the beginning, the chances that the teacher will choose a student who has forgotten his lunch are 2/10, or 1/5.

If the teacher now chooses another student from the remaining 9 students, the chances of his choosing a student who has forgotten his lunch are 1/9, since one of the forgetful students has already been removed from the original group of 10 students, and there are only 9 in the group remaining.

The probability that both students forgot lunch is (1/5)(1/9), or 1/45.

A bag contains 40 marble 12 red and 16 yellow what is the probability that a blue is randomly seclected
lora16 [44]

Answer:

Fraction=3/10

Decimal=0.3

Percent=30%

Step-by-step explanation:

First we have to add 12+16 so we can find how many marbles are left

12+16=38

Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles

40-38=12

There are 12 blue marbles.

Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.

Probability=

12/40

Simplify

12/40

6/20

3/10

Probability

Fraction=3/10

Decimal=0.3

Percent=30%
