Answer:
B
Step-by-step explanation:
The angle at the centre is equal to the arc that subtends it , thus
∠ ABC = arc AB = 75° → B
First take note of her total amount of money, the amount of magazine cost, and the total weeks they purchased it.
Total: $88
Cost: $3.75
Weeks: 5
Now setup and equation.
88-(3.75 x 5)
88-18.75=69.25
So she will have $69.25 after the 5 weeks of purchasing magazines
If we change everything to the same denominator it will look like this. 24/30 and he wants to take 10/30. 24/30 - 10/30 is 14/30 so 14/30 - 10/30 is 4/30. *He can take 2 1/3 pieces*
We know that to find the area of the entire circle, we are going to use the equation:

And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.
Now we can use this radius in the equation:


Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide
by 5 to find the area of each section:

Each section has an area of
or, using 3.14 for pi,
.
Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:

Therefore, the answer is C) 45.2
