2 groups if 4 bicyclists or 4 groups of 2 bicyclists. Well it's only 1.75 per truck so since there were 4 trucks 4•1.75=7.00 :)
Since the temperature starts at 40 degrees F at sunrise and increases 4 degrees every hour afterward, we can begin our equation.
If you visualize the graph, the y-axis (left side) will denote the degrees and increase slightly every hour. The x-axis (at bottom) will show the hours as they pass by. In slope-intercept form, the b must be 40 degrees, since this is where we start, and the slope m must be 4, since this is the amount the temperature is changing every hour.
Therefore y=4x+40
This equation will tell you the temperature (y) at any hour (x).
Answer:
A) (x - 5)² = 36
Step-by-step explanation:
x² - 10x - 11 = 0
A) CORRECT
(x - 5)² = 36
x² - 10x + 25 = 36
x² - 10x + 25 - 36 = 0
x² - 10x - 11 = 0

Let the total number of teachers be x
Given:
The ratio of the number between male and female teachers is 5:9
Then the number of female teachers is 81
So 9/14*x=81
or, x=81/9*14
or, x=9*14
Therefore x=126
So the total number of teachers is 126.
Hence the number of male teachers =
5/14*126
=5*9
=45
Hence, the number of male teachers is 45.
