The starting rectangle (on the left) is larger than the ending rectangle (on the right). This means the scale factor is some value between 0 and 1, not including 0 or 1 itself.
To find the scale factor, we divide corresponding sides. We divide the vertical side 1.5 of the figure on the right over its corresponding pair on the left.
So,
scale factor = (new)/(old) = 1.5/6 = 0.25
Since 0.25 = 1/4, this means that the rectangle on the right is 1/4th as small compared to the one on the right.

50.2
Step-by-step explanation:
202/4=50.2
b)about how much orange juice and pop do you need to serve 15 people? 20 people?
plz say how you answered this
O : P => 2 : 5
(a) 1 liter of pop to serve 7 people
=> 5 units = 1
1 unit = 1 / 5
Orange juice => 2 units
Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters
(b) If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people
i.e. 2.14 liters
As the ratio of O : P = 2 : 5,
5 units = 2.14
1 units = 2.14 / 5
For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people
Pythagorean theorem:
a^2+b^2=c^2
substitute:
10^2+13^2=c^2
simplify:
100+169=c^2
simplify:
269=c^2
take the square root:
c=16.4
The answer is 16.4
