Perpendicular lines have slopes that are negative reciprocals
so if m1 = -3
the perpendicular line has a slope of 1/3
Answer:
13/20
Step-by-step explanation:
find the greatest common denominator
Since lateral surface of an object is the area of all the sides of the object, except the area of its base and top.
It is:
7 * 3 = 21
21 * 2 = 42
12 * 3 = 36
36 * 2 = 42
42 + 42 = 84 in2
and there goes your answer.
A: 84 in2.
Let us assume last year the price of the item = $x.
After increase in price by 15% the new price = x + 15% of x = x+ 0.15x = 1.15x.
There is a 25% discount for employee.
25% of 1.15x = 0.25 × 1.15x = 0.2875 x.
Price after discount = 1.15x - 0.2875 x = 0.8625x.
The employee pays $172.50.
Therefore,
0.8625x = 172.50.
Dividing both sides by 0.08625.

<h3>x=200.</h3><h3>Therefore, last year the price was $200.</h3>
