For this question, we want to find out what 9 / 12 equals as a percent
or x / 100. Therefore, we have a proportion here and can say:
9/12 = x/100
Now, at this point, we can cross multiply to get:
900 = 12x
Now, divide both sides by 12 to get x alone and find that:
x = 75 <==== FINAL ANSWER
so 9 is 12% of 75!
I hope that helps you out! Please let me know if you have any other questions!
I'm pretty sure the answer is the last one:
6 x (40+2) = (6 x 40) + (6 x 2)
The 6 is distributed to the 40 and the 2
We are given
length of sides are
AB=7
AC=7
BC=6
now, we can use formula of area of triangle
where
A is area of triangle
r is radius of in-circle
s is semi-perimeter of triangle
step-1: Finding area of triangle
We can use
Heron's formula
a , b and c are values of sides
now, we can plug values
step-2: Finding radius(r)
we got
now, we can find radius

Set up multiplication of ratios so that they cancel out units that you do not need in your final answer...
