Answer:
62.5%
Step-by-step explanation:
We can write a proportion. We know that $50 is the original value and $80 is the marked up price. We don't know the marked up percentage. Let's call it x. We write equal ratios of
comparing percent and
comparing the 50 to the marked up price. We then set them equal.

We then cross multiply across the equal sign from numerator to the opposite numerator.
80(x)=50(100)
80x=5000
We divide to find x.
x=62.5
This means the bicycles are marked up 62.5% and the original value is 37.5%.
For a function, domain means the x value & range is the y value. So, simply, substitute each value in the domain for the x in your function, and you'll find the range.
Here're the answers:
g(0)=(0)^2+2
g(0)=2
g(2)=(2)^2+2
g(2)=6
g(5)=(5)^2+2
g(5)=27
g(9)=(9)^2+2
g(9)=83
Hope this helps!
Answer:
$103.75 for 8 hours
Step-by-step explanation:
8hr * 60min = 480min (for the total trip)
480min / 30min = 16 (30 minute intervals in her trip)
If the first half hour is a $25 dollar charge then,
$25 * 1 + $5.25 * 15 = $103.75 (for 8 hours)
Given:
The endpoints of a line segment are (-5,12) and (-5,0).
To find:
The coordinates of a points which divides the line segment in 2:1.
Solution:
Section formula: If a point divides a line segment in m:n.

Let point P divides the given line segment in 2:1. They, by using section formula, we get




Therefore, the coordinate of the point that partitions the given segment in the ratio 2:1 are (-5,4).
