Answer:

26 students per classroom

Step-by-step explanation:

To solve this, the ratio 234 students:9 classrooms must be converted to:

s students:1 classroom

To convert the ratio, 9 was divided by 9 to get 1, and so you must also divide 234 by 9 to maintain the same ratio, which gives us the answer:

26 students: 1 classroom

86%, 3/4, 0.682, 0.67, 5/8, 0.41

^ I converted the above to decimals first and then arranged them that way.

1/20 = 0.05 x 100 = 5%

Lewis rolls a number cube and then chooses a card from a set of cards numbered 1 through 5. What is the probability that he will

IceJOKER [234]

Answer:

$\frac{1}{5}=0.2$

Step-by-step explanation:

The general formula for a probability is:

$P=\frac{FavorableEvent}{TotalEvents}$

The favorable events for the cube to fall in a even number are:

2, 4, and 6 ⇒ 3 favorable events

and in the cube the total events are:

1, 2, 3, 4, 5, 6 ⇒ 6 total events

So the probability of rolling an even number in the cube is:

$P=\frac{3}{6}\\\\\\ P=\frac{1}{2}$

Now we do something similar to find the probability to choose a card with an even number.

The favorable events for an even numbered card are:

2, 4 ⇒ 2 favorable events

and the total number of events in the cards is:

1, 2, 3, 4, 5 ⇒ 5 total events

Thus, the probability to choose an even numbered card (according to the probability formula) is:

$P=\frac{2}{5}$

And finally, since we want both things to happen we must multiply both obtained probabilities:

the probability that he will roll an even number and choose an even numbered card:

$P=\frac{1}{2}*\frac{2}{5} \\ \\P=\frac{2}{10} \\\\P=\frac{1}{5} =0.2$

The probability is 1/5 which is equal to 0.2 or 20%

A square pyramid has a height of 6 units and a volume of 70 units3. If a square prism has the same base area and volume as the s

inysia [295]

Answer:

The height is 2 units

Step-by-step explanation:

Find the area of the base of the square pyramid

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base and H is the height of the pyramid

we have

$H=6\ units$

$V=70\ units^{3}$

substitute in the formula and solve for B

$70=\frac{1}{3}B(6)$

$B=70/2=35\ units^{2}$

step 2

Find the height of the square prism

we know that

The volume of the square prism is equal to

$V=Bh$

where

B is the area of the base and h is the height of the prism

we have

$B=35\ units^{2}$

$V=70\ units^{3}$

substitute in the formula and solve for h

$70=(35)h$

$h=2\ units$
