<u>Given:</u>
Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12 feet. If you move 3 feet west, the height is 10 feet.
We need to determine the slope.
Let x denote the standing place.
Let y denote the height.
Writing the given as coordinates, we get;
(0,12) and (3,10)
<u>Slope</u>:
The slope can be determined using the formula,
Substituting the coordinates (0,12) and (3,10), we have;
Thus, the slope is
ANSWER
EXPLANATION
The given non-linear function is a hyperbola with equation:
Since the boundary lines are dashed lines, the inequality should be either < or >.
Since the outer portion is shaded, the inequality is
8x - amount of boys
7x- amount of girls
8x + 7x = 195
15x= 195 ( divide by 15)
x= 13
8x = 8 x 13 = 104
7x = 7 x 13= 91
there are 104 boys, and 91 girls.
Answer:
Here is it given 52 men can do a piece of work in 35 days .
Which means total work is 52*35
Therefore total work = 52*35 = 1820.
Now 28 men are alloted to do same work
Let's consider the days taken by 28 men is x
We cans say that 28 men take x days to complete the work
28 * x = 1820
x = 1820/28
x = 65
