We know that out of 3000 people, 9 had a alergic reaction.
in this case our 100% is 3000, and we want to know what percentage is equivalent to those 9 that had a mild allergic reaction.
here we can use the rule of 3, this is:
if 3000 is equivalent to 100%, then 9 is equivalent to:
(9/3000)*100% = 0.3%
32.50-18.50=14
he spent $14 on gas, but we want how many gallons, one gallon is 3.50
so 14/3.50=4
She put 4 gallons in the can
9/250 is in it's simplest form
If you wanted it's decimal form, it is 0.036
I've posted my answer together with the image I think this problem required.
1. Yes.
Since, to be a triangle, the sum of the smallest two sides must be greater than the third side, the triangle can be formed.
3 + 22 > 24
2. This triangle is a right triangle.
180 - 60 - 30 = 90
90 degrees is a right angle.
Hope this helps!
