Answer:
a. $4.17
b. 233.3%
Step-by-step explanation:
a. The proportion the markup (m) is to the total (t) is ...
m : t = 7 : 10
The total is the cost (c) plus the markup, so we have ...
m : t = 7 : 10 = m : (m +c) = 7 : 7 +3
Then the ratio of total price to cost is ...
t : c = 10 : 3
The menu price of the pie slice will be ...
$1.25 × 7/3 ≈ $4.17
__
b. The ratio of markup to cost is ...
m : c = 7 : 3 ≈ 2.333 = 233.3%

Area of the square = 11*11 = 121
Area of the circle = pi r^2 = pi*1^2 = 3.142
Part A
P( hitting the circle = 3.142 / 121 = 0.026 which is closer to 0.
Part B.
P( hitting the white portion) = 1 - 0.026 = 0.974 which is closer to 1.
Answer: 1
Step-by-step explanation:
If you get a 10/10 on something, it’s 100%. If you get a 9/10, it’s 90%. If you get a 9/9, it’s 100%. So, if you get 8/9, it’s roughly 90% but not exact. It’s actually 88.8%
