Answer:
1. 20%
2. 0.37
3. 60%
4. 8 out of 10
5.
Step-by-step explanation:
Percentages are just dividing by 100 because all percentages must equal up to 100 such, as 50% and 50% (50+50=100) or 60% and 40% (60+40=100)
So divide the percentage ( basically just the number not, the %) by 100. 20(%)÷ 100 = 0.2 (take out the % when you do it). 60 ÷ 100 = 0.6
8 out of 10 is 8 ÷ 10 (0.8) if. it was 10 out of 8. it would look like which you can divide and get 1.2 because the line above the 8 means divide.
and is what i just explained above ↑ divide 5 and 6, which is .83 (it is .8333333333 to infinity and beyond, but I just said 3 because dont have that line)
now that you have everything in decimals. Sort them!
0.2 (20%)
0.6(60%)
0.37
0.8 (8 out of 10)
5/6 (0.83)
(↑ not the right answer the one in the answer box is.)

Answer:
- g(20) > f(20)
- g(x) exceeds f(x) for any x > 4
Step-by-step explanation:
As with most graphing problems not involving straight lines, it works well to start with a table of values. Pick a few values of x and compute f(x) and g(x) for those values. Plot the points and draw a smooth curve through them.
As in the attached, your table will show that there are two points of intersection between f(x) and g(x), and that for values of x more than 4, g(x) becomes much greater very quickly. Both curves rapidly reach the top of your graph space.
To find whether f(20) or g(20) is greater, you can evaluate the functions for that value of x.
f(20) = 20² = 400
g(20) = 2²⁰ = 1,048,576
Clearly, g(20) has a greater value.
