Answer:
The answer is 24:32
Step-by-step explanation:
You have 24 girls + 8 boys= 32.
Giving ratio of 24girls: 32 children
= 24:32
You do a little method called cross multiplication and helps to solve proportions and how to find percents in your case. My iPad won't really show fractions but I'll use the dash marks.
1/10=?/100
Multiply 1 by 100 and you get 100 and then divide by 10 which will get you 10 percent.
Another example would be 4/5=?/100
Again you do cross multiplication and it would be 4 times 100 and you get 400 and then you divide by 5 and the answer is 80 percent.

Step-by-step explanation:
the mean value is the sum of all values divided by how many values there are.
so,
(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7
-7° F is the mean temperature of the 5 cities.
Answer:
Step-by-step explanation:
<h3>Q13</h3>
The greater the angle the greater the opposite side
<u>Sides in ascending order:</u>
- AB = 17, AC = 18, BC = 21
<u>Angles in same order</u>
<h3>Q14</h3>
<u>As above, sides in ascending order:</u>
- AB = 15, AC = 16, BC = 17
<u>Angles in same order</u>
<h3>Q15</h3>
<u>Exterior angle equals to sum of non-adjacent interior angles</u>
- 142° = x + 66°
- x = 142° - 66°
- x = 76°
<h3>Q16</h3>
<u>Same subject and isosceles triangle:</u>
- x + x = 158°
- 2x = 158°
- x = 79°
<h3>Q17</h3>
<u>Same subject</u>
- m∠QSR = m∠QPS + m∠PQS
- 2x = x + m∠PQS
- m∠PQS = 2x - x
- m∠PQS = x
ΔPQS has two angles with the measure of x, hence their opposite sides are congruent and the triangle is isosceles
Answer:
5. x = -3
6. x = -2
7. x = 1/2
8. x = 9/5
