For a. divide 125 by 300 then multiply by 100
The answer for a. is 41.66%
For b. convert percentage to decimal divide by 100 then multiply 0.15 by 2.25 to get 0.3375. Round it off to 0.34 and subtract that from 2.25 to get
The answer for b. is $1.91
For c. you have to figure out the difference first. 2.50 minus 2.00 is 0.50
So then what percent of 2.00 is 0.50
Divide 2.00 by 0.50 to get 4.
The answer for c. is 4%
Honestly this was kinda rushed because I'm in the middle of a quiz so yea hope this helps you.

To calculate the area of a Hexagon you could find how many right triangles are in the hexagon and calculate the area of those right triangles to the amount of right triangles there are in the hexagon. A Hexagon has 6 isosceles triangles with bases of 15 ft and height of 4 ft, which means it has 12 right triangles with base of 7.5 and height of 4ft,. Area of the right triangle is bh/2 (base times height divided by two) which base is 7.5 and height is 4 so bh=30 and divided by two is 15, there are 12 right triangles so you can multiply 15*12 and that's the area of the Hexagon which is 180 degrees

The standard formula for a parabola are
(x-h)^2 = +/- 4a (y-k) or (y-k)^2 = +/- 4a(x-h)
where
(h,k) is the coordinates of the vertex
a is the length of the focus from the vertes
+4a if the parabola opens upwards or to the right
-4a if the parabola opens downwards or to the left
The vertex (2,13) is situated in the 1st quadrant of the Cartesian plane. It only has y-intercept. This means that it only passes the y-axis once. Therefore, the parabola must open downwards and it passes the x-axis twice. The intersections at the x-axis are the x-intercepts. If the parabola has 2 x-intercepts, then the equation would be (x-h)^2 = -4a(y-k).
Let's use the y-intercept (0,5) to determine 4a:
(0-2)^2=-4a(5-13)
4a = 0.5
Therefore, the equation of the parabola is (x-2)^2 = -1/2(y-13). To find the x-intercepts, let y=0.
(x-2)^2 = -1/2(0-13) = 6.5
x-2 = +/- √6.5 = +/- 2.55
x = 4.55 and and -0.55
The x-intercepts are (-0.55,0) and (4.55,0).
