If 10 percent of your day is spent studying, how many hours do you devote to studying? Use 24 hours as the length of a day.

Answer:
2 hours and 24 minutes (2.4 hours)
Step-by-step explanation:
Our output value is 24. We represent the unknown value with x. From step 1 above, 24=100, and x=10. This results in a pair of simple equations:
24=100%
x=10%
By dividing equation 1 by equation 2 and noting that the right hand sides of both equations have the same unit (%); we have:
Again, the reciprocal of both sides gives
x=2.4
Therefore, x equals 2.4.
The 2 in 2.4 represents 2 hours. The 0.4 in 2.4 represents minutes, as there isn't enough to fill a full hour.
4/10ths of 60 is 24.
Therefore, you would be devoting 2 hours and 24 minutes to studying.

Answer:
In order to find the slope (m), and the y-intercept of this coordinate pair, you must complete rise over run.
This is represented by y2-y1, x2-x1. This can be represented like so:
-4-0 = -4
5--4 = 9
Here, we have concluded that our slope is -4/9.
Now, we must convert this into point slope form. Point slope form is y-y1=m(x-x1). This will look like this in our situation:
y+4=-4/9(x-0)
To solve, distribute the -4/9 first, which will leave you with:
y+4=-4/9x+0
Now, subract the 4 to both sides of the equation.
Our final answer looks like: y=-4/9-4.
<em>-</em>
<em>SLOPE: -4/9</em>
<em>Y INTERCEPT: -4 </em>

Ex
137÷5=
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.
