The slope of the line MN where M (9,6) and N (1,4) can be obtained by obtaining the rate of the rise over the run. This is shown below:
(y2 - y1)/(x2 - x1) = (4 - 6)/(1 - 9) = (-2)/(-8)
m1 = 1/4
The slope of the line perpendicular to line MN can be obtained by taking the negative reciprocal of the slope of line MN.
m1 = 1/4
m2 = -1/m1 = -1/(1/4) = -4
Therefore, the slope of the line perpendicular to line MN is -4.
27÷3=9
9 is the original number.
9×2=18
the answer is 18.
if you wanted to check your work, 27:18 simplifies down to 3:2.
Answer:
4) A
5) E
Step-by-step explanation:
#4
Cross multiply the equation and you get:
Since 
is the same thing as 
, you can change the equation into 
Cancel out the y on the top and bottom and you get 1/10
#5
, simplify and you get 
so x=15
is equal to 
after you plug in x, and that is equal to 9
The dimensions if the field are: the length is 360 feet; the width is 160 feet.
Answer:
A) 3hrs
Step-by-step explanation:
Fission is the action of dividing or splitting something into two or more parts.
So, we're going to continuously multiply our answers by 2 until we get 360
10 x 2 = 20 30min
20 x 2 = 40 1hr
40 x 2 = 80 1hr 30min
80 x 2 = 160 2hrs
160 x 2 = 320 2hrs 30min
320 x 2 = 630 3hrs
