I guess the only way to use subtraction is to take the total area of the grid and subtract it by the total area around the figure. So it since it is a 10 by 10 grid, it would be 100 (since 10*10=100) minus the area around the shape.

Step-by-step explanation:
the total distance traveled by a person sitting in the Ferris wheel would be
(if the full ride is 2 revolutions) => 2 ( 2πr) [ 2 times the circumference of the ferris wheel]
therefore,
=> 2 x (2 x 3.14 x 200)
=> 2 x 1256
=> 2512 feet
1) There are 90 + 74 people who are "at least 175 cm tall" (164 ppl)
2) probability is 164/250 = 0.656
D. 0.656
Answer:
p = (7r+16) / (4-q)
Step-by-step explanation:
4p - 7r = pq + 16
Add 7r to both sides.
4p = pq + 16 + 7r
Subtract pq from both sides.
4p - pq = 7r + 16
Factor out p from the left side.
p(4 - q) = 7r + 16
Divide both sides by (4 - q).
p = (7r + 16)/(4 - q)
The 7r and the 16 could be in either order, like 7r+16 or 16+7r. You could show that the answer is a fraction with 7r+16 on top and 4-q on the bottom. If you are writing or on the computer selecting a fraction that is stacked you don't need need the parenthesis.
