AREA= 1/2 BASE * HEIGHT
9/10 = 1/2x*3/5
x= 9/10*10
x=9
Thus, the base is 9
To find the decimal of 2/9 , u have to do 2 divided by 9 which equals 0.22222222222
If m varies directly with x, then that means that you have to find the slope. To make it easier, m = y-variable, and x = x-variable.
Because you are trying to find your constant of variation (another word for slope, rate of change, etc.), the change of y over the change of x is your equation. in other words, divide your m variable by x.
When m = 60 and x = 6, you can set it up. 60 / 6 = k; and k = 10 when solved. Since 10 is not one of the answer choices listed in your answer key, I believe that your answer is NONE OF THE ABOVE.
I hoped this helped you.
Answer:
<u>(7.5-2.1) /2</u>
<u>If the shortest side measures 2.1 m</u>.
<em>7.5-2.1 =5.4.</em> Then divide by 2 each side is 2.7m
William needs 102.6 fencing in all because 76.9 plus 25.7 equals 102.6, hope this helps!
