A rational number is any number that can be made into a fraction and is either repeating or stops when in decimal form.
Rational numbers between 3 and 3.5 would be 10/3 (3.33 repeating), and 13/4 (3.25).
Hope this helps!! :)
Answer:
35° and 85°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Since one angle = 60° then the sum of the other 2 angles = 120°
Sum the parts of the ratio 7 + 17 = 24 parts, hence
= 5° ← value of 1 pat of the ratio, hence
7 parts = 7 × 5° = 35°
17 parts = 17 × 5° = 85°
note that 60° + 35° + 85° = 180°
<h2><u>Mean and Median</u></h2>
<h3>solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17</h3>
<h3><u>Mean</u></h3>
To find the mean of a data set, use the formula:
<u>mean</u> = <u>sum of the data points</u>/<u>number of the data points</u>
We will determine the sum of the data points.
- 20 + 10 + 15 + 18 + 12 + 17 = 92
Since the number of data points is 6, we will divide the sum and the number of data points as shown in the formula above.
<u>Answer:</u>
- The mean of the data set is <u>15.3</u>.
<h3><u>Median</u></h3>
To find the median of the data set, arrange the data set into ascending order and the value in the middle is the median. The median should be an even number.
- 20, 10, 15, 18, 12, 17
- 10, 12, 15, 17, 18, 20
The middle value is 15 and 17. Find out their sum and divide it into 2.
<u>Answer:</u>
- The median of the data set is <u>16</u>.

7/(b-36)=28/b
28b-1008=7b
21b=1008
b=48
a/72=28/b
a=72x28/48
a=42
1.25 times 15 will get you how much she has used, and then subtract that from 35.4 to get the amount left in the bottle
