Answer:
Step-by-step explanation:
To calculate slopes use the equation rise / run.
So count how many boxes up and divide that number by the number of boxes across to find the slope.
Make sure that you are using exact point on the slope (where the dots are on the line) to make it easier to calculate.
Also start from the left-most dot (look at slope B example)
For example for the slope of A:
2 blocks up, 5 blocks to the right so the slope is 2/5
But for slope B, since the first dot is higher than the second dot:
5 blocks down (-5), 1 block right so the slope is -5/1 or just -5.
Answer:
117.8 cubic inches
Step-by-step explanation:
Here is the formula pi r^2 h
pi * (2.5)^2 * <u>6</u> = 117.75 cubic inches
Change the '6' if it is a different number than 6%
Answer:
7m+3
Step-by-step explanation:
distribute the - to 7m+1
14m+4-7m-1
now add like terms
7m +3
It will be irrational. The sum of any irrational and rational number will ALWAYS result in a irrational answer. Khan Academy has a video on this if you want to watch it.
Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
