Answer:
Its the first option
Step-by-step explanation:
Factor the denominator:-
q^2 - 7q - 8 = (q - 8)(q + 1)
The denominator must be > 0 so the restriction is q ≠ -1 and q ≠ 8.
The Pythagorean Theorem: (a² + b² = c²)
1. Substitute the known values
20² + 15² = c²
400 + 225 = 625
2. Solve
625 = c²
Divide and solve for both side, simplify and you get:
Answer: C = 25
Take the total: $79.99
Subtract the shipping cost: $4.99 ($75)
Divide that by the number of socks: 75/15
=$5 per sock with the discount
Take the discount of 20% and multiply that by the sock price $5 - 5 x .20 = 1
Add that to the sock price: 1 + 5 = 6
$6 per sock without the discount is your answer
Answer:
Step-by-step explanation:
Cone
Givens
r = 1.5 inches
h = 4 inches
Formula
V = 1/3 pi r^2 h
V = 1/3 3.14 * 1.5^2 * 4
V = 1/3* 3.14 * 2.25 * 4
V = 9.42
Semi sphere
Givens
r = 1.5
Formula
V = 2/3 * pi * r^3
Solution
V = 2/3 * 3.14 * 1.^3
V = 7.065
Total
V = 9.42 + 7.065
V = 16.485
Rounded to the nearest 1/100
V = 16.49
