Everything about number one is because it's a half of circle so its area = 1/2 ¶r^2 and its perimeter = ¶r
Answer:
I am not sure but if you divide those 2 numbers such as dividing 10 by 15 you will get 0.666666666667 but if you round it you will have 67%

Answer:
85%
Step-by-step explanation:
Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother.
The number of baseball cards he gave to his brother is :
120 - 18 = 102 baseball cards
The percent of the baseball cards he gave to his brother is calculated as:
(Number of baseball cards given to his brother/ Total number of baseball cards) × 100
= 102/120 × 100
= 85%
The percent of baseball cards Evans gave his brother is 85%
8x + 5y = 2 → 5y = - 8x + 2 → y = (-8/5)x + 2 ⇒ m = -8/5
perpendicular slope = 5/8
Point-Slope formula: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the given point
y - (-7) = (5/8)(x - 2)
y + 7 = (5/8)(x - 2)
8(y + 7) = 5(x - 2)
8y + 56 = 5x - 10
8y + 66 = 5x
66 = 5x - 8y ⇒ 5x - 8y = 66
Answer: 5x - 8y = 66
