Find the probability of Red/small.
Red = large + small
large = 8
Small = 12
Plug in 8 for large, and 12 for small
Red = 8 + 12
Red = 20
Now we know that the total red = 20
Do the same with small
3 small blue
12 small red
Small = blue + red
Small = 3 + 12
Small = 15
Note that red is first then small. Put red over small
Remember that red = 20, small = 15
20/15 is the fraction you need.
However, note that it says "reduce your answer" at the bottom
Divide 5 from numerator and denominator
(20/15)/(5/5) = 4/3
4/3 is your answer
hope this helps
Answer:
56.26
Step-by-step explanation:
An isosceles triangle has two sides that are the same length, and one side that is the same length. We have two sizes, so two find the greatest possible perimeter we must assume that the greater size is the value for the two sides, and the smaller size the value for the single side. In other words:


Nonlinear because its not changing in y values
