Answer:

Step-by-step explanation:
Given

--- Those that do not get recommended amount of exercise
Required
The percentage that do not get the recommended amount of exercise
From the question, we have 79% to be the percentage of adults that do not get the recommended amount of exercise. This 79% represents the required percentage
Hence:

We are given a circle graph that shows the time spent on homework last week.
Jacob spent a total of 16 hours doing homework.
The time spent on doing science homework is given by

The time spent on doing band practice is given by

The difference between the time spent on science homework and band practice is

Therefore, Jacob spent 2 more hours on science homework than band practice.
The y-intercept is (0,-1)
Answer:
40 or 45%
Step-by-step explanation:
Answer:
15.1
Step-by-step explanation:
We know that the area of the circle is
, but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.
Area of shaded region = 
where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.
Area of shaded region =
= 15.1
Another way to think about it is that the area of the total circle is
, multiplying it by a fraction, a number less than 1, would give us a smaller value.
Hope this helps.
