Answer:
If the two polygons are similar, then their sides are proportianal.
We see that sides in the larger polygon are two times as long as the sides of the smaller polygon.
So, if the larger polygon has a side length of 13, then the smaller polygon would have a side length of 13/2, or 6.5

A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively. If
a:b= 2:3, b:c=4:5, find the length of each side of the triangle.
Answer:
The length of the sides are 64 cm, 96 cm and 120 cm.
Step-by-step explanation:
Perimeter of a triangle:
The perimeter of a triangle is the sum of it's sides.
A triangle has a perimeter of 280 cm, and its side lengths are a, b and c respectively.
This means that:
[tex]a + b + c = 280[/tex]
a:b= 2:3
This means that:
[tex]\frac{a}{b} = \frac{2}{3}[/tex]
[tex]2b = 3a[/tex]
[tex]b = \frac{3a}{2}[/tex]
b:c=4:5
This means that:
[tex]\frac{b}{c} = \frac{4}{5}[/tex]
[tex]4c = 5b[/tex]
[tex]c = \frac{5b}{4}[/tex]
[tex]c = \frac{5*3*a}{4*2} = \frac{15a}{8}[/tex]
At the original equation:
We replace b and c in function of a. So
[tex]a + b + c = 280[/tex]
[tex]a + \frac{3a}{2} + \frac{15a}{8} = 280[/tex]
Multiplying everything by 8
[tex]8a + 12a + 15a = 280*8[/tex]
[tex]35a = 280*8[/tex]
[tex]a = \frac{280*8}{35}[/tex]
[tex]a = 64[/tex]
Sides b and c:
Since we have a, we can find sides b and c:
[tex]b = \frac{3a}{2} = \frac{3*64}{2} = 3*32 = 96[/tex]
[tex]c = \frac{15a}{8} = \frac{15*64}{8} = 15*8 = 120[/tex]
The length of the sides are 64 cm, 96 cm and 120 cm.

How many people survived the water park?
Answer:
70 people visited the waterpark.
Step-by-step explanation:
Since you know that 250 people were surveyed and of those people, 28% of them visited the waterpark, you have to find out what 28% of 250 is. 28% of 250 is 70, so 70 people visited the waterpark.

A tablet computer listed at an original price of $250 is placed on sale for
20% off the original price. Bob, an employee of the store, gets an
additional 30% off the sale price. What price would Bob pay to purchase
the tablet computer?
$100
$125
$200
$140
Answer:
$140
Step-by-step explanation:
250 decrease 20% =
250 × (1 - 20%) = 250 × (1 - 0.2) = 200
200 decrease 30% =
200 × (1 - 30%) = 200 × (1 - 0.3) = 140
