Answer:

9. No

10. Yes

Step-by-step explanation:

The first one is not, since you have (3, 3) and (3, 9).  In a function, each x maps to a single y.

What is 20/25 as a percentage
timurjin [86]
Hey there! 
Let solve this problem step by step :)

1. Convert 20/25 into a decimal. In order to do this, you will need to divide the numerator (the top part of the fraction) with the denominator (the bottom part of the fraction). 

So, \frac{20}{25} as a decimal would be 0.8. (We divide 20 by 25)

2. Now, we take the decimal and multiply it by 100. To make it even simpler, just move the decimal, two places to the right. This makes it the percent. So,

0.8 ----> 80%

The final answer is 80%

Thank you!

A school district has two high schools. The district could only afford to hire 13 guidance counselors. Determine how many counse
Umnica [9.8K]

Answer:

a)

Lowell: 4 counselors

Fairview: 9 counselors

b)

2 new counselors

Step-by-step explanation:

How many counselors should be assigned to each school using Hamilton's method?

Number of students

Lowell: 3584  

Fairview: 6816

Total number of students: 10400

Divisor D = (Total number of students)/(number of counselors)= 10400/13 = 800

<u>Temporal assignment</u>

3584/800 = 4 + 0.48 ==> 4 counselors for Lowell

6816/800 = 8 + 0.52 ==> 8 counselors for Fairview

There is one counselor left. According to Hamilton's method she should be assigned to the school with the largest remainder, that is Fairview.

<u>Final assignment</u>

Lowell: 4 counselors

Fairview: 9 counselors

The next year, a new school is opened, with 1824 students. Using the divisor from above, determine how many additional counselors should be hired for the new school

1824/800 = 2 + 0.28

<em>Two new counselors should be hired.</em>
