Answer:
D
Step-by-step explanation:
8% in decimal form is written out as 0.08, so right away the answer is either C or D.
Then if you have "s" = 1875, you would get:
350 + (0.08 × 1875) = 500
That would mean any number greater than 1875 will give you a total more than 500.
Therefore the answer is D.
Answer:A
You just have to use the table to figure out where the points are on the graph.
Answer:

Step-by-step explanation:
One way to do this would be to find the circumference of the entire circle and divide it by 4, considering that the arc measure is 90 degrees
The radius is 1, and the circumference can be found by taking 
So, the circumference of this circle is 
Now, all we have to do is divide that by four to get our answer

Think of fractions as an equation for a decimal. So treat it as such.
32/75=0.427
3/11=0.28
-5/8=-0.625
-7/10=-0.7
21/7=3
-179/99=-1.81
