If half of Karen's collection (4) is 1/3 of Mary's, and half of Karen's collection is 2, then 2 x 3 is how many Mary has, right? Once you know how many books Mary has, you can add how many Karen has to get your answer.
Question:
What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the values of radius and central angle are not given.
However, I'll answer the question using the attached figure.
From the attached figure, the radius is 3 unit and the central angle is 120 degrees
The area of a sector is calculated as thus;
Where 
represents the central angle and r represents the radius
By substituting 
and r = 3
becomes
square units
Solving further to leave answer as a decimal; we have to substitute 3.14 for 
So, becomes
square units
Hence, the area of the sector in the attached figure is 
or 9.42 square units

Answer:

Step-by-step explanation:
So,
I'm assuming you want me to make a formula for figuring your points after any given month assuming that you use the site at least once a month and you don't spend your points.
After one month, you will have your base 100 points plus an additional 10 points.
100 + 10 = 110
After two months, you will have gained an additional 10.
110 + 10 = 120
We can put this into a function, where P is your points, and m is the number of months you use the site.
P(x) = 100 + 10m
So after 500 months, you will have:
P(x) = 100 + 10(500) = 5100 points!
This is identical with:
y = 100 + 10m
and
y = 10m + 100
So this can be graphed as a linear equation/function with a y-intercept of 100 and a slope of 10/1.
