<span>To estimate 586 - 321, you can round the numbers up or down to the nearest five.
586 can either become 570, rounding up, or 585, rounding down, which is closer. 321 becomes 320. It's not close enough to 325, nor to 315, for either of those to be good choices. 570 - 320 = 250 and 585 - 320 = 265. The actual solution to the original problem is 265, so, the second estimate, because they both go down by 1, is the closest.</span>

An album sells for $17.00 through an online music service. If the album is 20% off, and sales tax is 6%, what is the total price
V125BC [204]

Answer:

$14.42

Step-by-step explanation:

Price of Album - $17.00 * .20 = 3.4 (this is the discount)

Then subtract 3.40 from 17.00 to get 13.60

Add the sales tax in by doing $13.60 * 0.06 = $0.82

Add that to the 13.60 to get $14.42 for the total after discount and after tax.

Is each line parallel, perpendicular, or neither parallel or perpendicular to a line whose slops is -3/4?
Ymorist [56]

Answer:

Line M is neither.

Line N is perpendicular.

Line P is neither.

Line Q is parallel.

Step-by-step explanation:

Parallel lines are lines whose slope are the same. Line q is the exact same slope. It is parallel.

Perpendicular lines are lines whose slopes are the negative reciprocal of each other \frac{a}{b}, -\frac{b}{a}. Line n is 4/3 and is perpendicular.

Line m and p are neither.
