Answer:
To the nearest percentage, percent increase is 33%
Step-by-step explanation:
Mathematically;
Percentage increase = (new - old)/old * 100%
new = 48 hours
old = 36 hours
% increase = (48-36)/36 * 100%
12/36 * 100%
1/3 * 100%
= 33.33%
Answer:
A the table display qualitative data, C two teachers do not wear glasses, E a total of 6 teachers were polled
1. Find the slope of the given line. Do this by solving <span>3x-7y+14=0 for m:
3x + 14 = 7y, which gives us m = 3/7.
2. Find the slope of a line perpendicular to this one. It's the negative reciprocal of m = 3/7, or -7/3.

Regroup terms
2(x + 2) = 1
Divided both sides by 2
x + 2 = 1/2
Subtract 2 from both sides
x = 1/2 - 2
Simplify 1/2 - 2 to -3/2
<u>x = -3/2</u>
