Answer:

A: 19:26 B:7:8 C:26:45

Step-by-step explanation:

<u>Question A</u>

First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,

<u>Boys</u>

9+10=19

<u>Girls</u>

12+14=26

Now that you have the total number of boys and girls you make this ratio,

19:26

That is the final answer

<u>Question B</u>

For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,

<u>Fifth Graders</u>

12+9=21

<u>Sixth Graders</u>

14+10=24

Now that you have the total number of both of the different grades you make this ratio,

21:24

You can simplify this by finding the lowest common factor which would be

7:8

<u>Question C</u>

To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.

<u>Girls</u>

12+14=26

<u>All</u>

12+9+14+10=45

Now with the total number of both you will form a ratio

26:45

This is your final answer because you cant simplify this any further

A school group wants to rent part of a bowling alley to have a party. The bowling alley costs $500 to rent, plus an additional c
Firlakuza [10]

Answer:

If there are N students, the total cost will be:

C(N) = $500 + $5*N.

And we want the amount that each student pays to be equal or less than $15.

then:

C(N)/N ≤ $15.

Then the inequality that represents this situation is:

($500 + $5*N)/N ≤ $15.

Now, let's solve this:

($500 + $5*N) ≤ $15*N

$500 ≤ $15*N - $5*N

$500 ≤ $10*N

$500/$10 ≤ N

50 ≤ N

So the minimum number of students needed is 50.

A study shows that employees who begin their workday at 9:00 a.m. vary their times of arrival uniformly from 8:40 a.m. to 9:30 a
jeka94

Answer:

0.2 or 20%

Step-by-step explanation:

If the times of arrival vary uniformly, there is an equal chance of an employee reporting at any given time between 8:40 and 9:30.

The range between 8:40 and 9:30 is 50 minutes.

The range between 9:00 and 9:10 is 10 minutes.

Therefore, the  probability that a randomly chosen employee reports to work between 9:00 and 9:10 is:

P(9:00\leq X\leq 9:10)=\frac{10}{50}=0.20=20\%

The probability is 0.2 or 20%.
