Answer:
The line passes through (1,1) and (3,2). Therefore, its equation is
Answer:
63
Step-by-step explanation:
Use the formula for the volume of a cylinder.
V = area of the base * height
area of the base = π (radius)^2
V = π(radius)^2 * height = π(8 in)^2 (18in) = 1,152π in^3
If you use π≈3.14, you get
V = 3,617.28 in^3

Answer: 0.85</h3>
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value
