Answer:
B the graph is a refelction over the x axis
Step-by-step explanation:
Below are the solutions:
A)
Ohio: 8.23 * 10^5
US: 3.19 * 10^8
B)
(3.19 * 10^8)/(8.23 * 10^5) = 3.19/8.23 * 10^8/10^5
= 3.19/8.23 * 10^3 = 0.387606318 * 10^3
= 387.606318
The population of US is 387 times larger than that of Ohio's
To solve this we'll put the question in this format: x% of y things = z things
We have the percent so we'll put in 60 for x.
Now the total number of balls will be considered y since we have the number of red balls but not blue ones. so we end up having..
60% of y balls = 720 balls
Of is another word for multiplication, therefore:
60/100*y=720
Solve for y
y=1200
So we have 1200 balls
