Answer:
Total number of pages is 540.
Step-by-step explanation:
Let mark read x be he number of pages per day and d be the number of days to finish the book.
Total number of pages = xd
Mark reads 18 pages less per day than originally planned, he will need 5 extra days to finish the book.
.... (1)
He reads 24 pages less per day, he will need 8 extra days to finish.
... (2)
Subtract 5 times of equation (2) from equation (1).
Substitute d=10 in equation (1).
Divide both sides by 5.
Total number of pages
Therefore , the total number of pages is 540.

Step-by-step explanation:
After signing up she received 75 points, so the number of points he needs to get a free ticket : 140 - 75 = 65
If she earns 6.5 points or each visit, she would have to visit 65/6.5 times to get a free ticket
65/6.5 = 10
Answer:
Area of the shaded region = 75.36 in^2
Step-by-step explanation:
You find the area of the large circle and divide it in half. You find the area of the small circle and divide it in half. Finally, you subtract the small half circle from the large half circle.
A = area
π = Pi = 3.14
r = radius= the distance from the center of the circle to the edge.
A = π * r * r A = π * r * r
A = 3.14 * 8 * 8 A = 3.14 * 4 * 4
A = <u>200.96</u> A = <u>50.24</u>
2 2
A = 100.44 in^2 A = 25.12 in^2
100.44 - 25.12 = 75.36 in^2
C=1/12
1/6x=2 so 1=12x
X=1/12
