Answer: It can always be written as a fraction.


Step-by-step explanation:

1. By definition, a rational numbers has the following form: \frac{a}{b}, where a and b are integers and b\neq0.

2. Therefore, when you add two rational numbers, the result it can always be written as a fraction.

3. An example is shown below:

\frac{3}{5}+\frac{1}{5}=\frac{4}{5}

The result is a fraction whose numerator and denominator are integers.

Given quadrilateral MATH is similar to quadrilateral ROKS calculate the value of MH Picture is below
tino4ka555 [31]
<h3>Answer:  MH = 7</h3>

=====================================================

Explanation:

The double tickmarks for quadrilateral MATH show that MA = TH. Since TH is 5 units long, this makes MA the same length as well.

For quadrilateral ROKS, we have RO = 15. For "MATH" and "ROKS" we have "MA" and "RO" as the first two letters of each four-letter sequence; meaning that MA and RO correspond together.

The ratio of the corresponding segments is RO/MA = 15/5 = 3.

The larger quadrilateral has each side length 3 times longer than the smaller quadrilateral's corresponding side lengths.

--------------

In short,

larger side = 3*(smaller side)

--------------

Using this scale factor of 3, we can find MH

larger side = 3*(smaller side)

RS = 3*(MH)

21 = 3*MH

3*MH = 21

MH = 21/3

MH = 7

A saleswoman received $40 per day, plus a commission of 2% on all sales over $300 per week. What was her salary for a 5-day week
ExtremeBDS [4]
2 % = 2/100 = 0.02 
So her salary is broken down into two parts. 
The systematic part is $40 per day for 5 days, so 40*5. 
The changing part is 2% of weekly sales over 300, so 0.02(1260-300). 

Salary = 5*40 +0.02(1260-300)=$219.20

Multiply. Express your answer in simplest form. 9 1/6 × 1 1/11
natka813 [3]

Answer:

10

Step-by-step explanation:

9 1/6 × 1 1/11

Change each number to an improper fraction

9 1/6 = (6*9 +1)/6 = 55/6

1 1/11 = (11*1 +1) /11 = 12/11

55/6 * 12/11

Rearranging

12/6 *55/11

2/1 *5/1

9. What's the least common multiple (LCM) of 2, 6, and 8?
algol [13]

Answer:

24

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

So

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>

6, 12, 18, <u>24</u>

8, 16, <u>24</u>

They all share 24 so this is the LCM

Hope this helps
