Answer:
The answer is 25%
Step-by-step explanation:
on the first year lets say town A and town B had a population of 100 (a town wouldn't have only 100 people but for simplicity lets do 100).
town A's population increases by 60%, 60% of 100 is 60, 100 + 60 = 160
town B's population decreases by 60%, 100 - 60 = 40
so now we have town A's population after 10 years and town B's population after 10 years, 160 divided by 40 = 4, and 100 divided by 4 equals 25, so the answer is 25%.

Given information
-----------------------------------------------
First showing : 1.30pm
Second showing : 4.15 pm
Inbetween : 1/2 hour break
-----------------------------------------------
Find the time the first showing ends
-----------------------------------------------
1/2 hours before 4.15pm
⇒ 30 mins before 4.15pm
⇒ 3.45pm
-----------------------------------------------
Calculate the duration of the firs show
-----------------------------------------------
1.30pm to 3.30pm = 2 hours
3.30pm to 3.45pm = 15 mins
Total duration = 2 hours 15 mins
-----------------------------------------------
Answer: 2 hours 15 mins
-----------------------------------------------
Answer: x=3.15
All you do is divide 13.23 by 4.2
<u>Let's take this problem step-by-step</u>:
<u>What does this problem ask us to find</u>:
⇒ <em>height</em>
<em />
<u>Now consider the formula for the Surface Area of a Cylinder</u>:
⇒ πr² + 2πrh
- r: length of the radius
- h: length of the height
<u>Now consider the information given to us</u>:
- radius' length: 5 cm
- Surface area: 110π
<u>Let's plug everything into the surface area formula</u>:
Thus the height is 8.5 cm
<u>Answer: 8.5 cm</u>

Hope that helps!
Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substituting values
= ( cross- multiply )
21x = 7(24 - x) ← distribute
21x = 168 - 7x ( add 7x to both sides )
28x = 168 ( divide both sides by 28 )
x = 6 → C
