Answer:
150/335, or 30/67
Step-by-step explanation:
Probability is expressed as the part against the whole (a fraction). All you have to do is divide how many people ran red lights by the total...and you're done!
Have a great day!
You can take it apart. There are a top and bottom (both the same) right triangle. So you can find the area of that by multiplying 8*6 and divide by two. Then multiply by two because there are 2 triangles.
You are left with three rectangular sides: One 10x10, one 10x6, and one 10x8.
So your whole equation looks like this: A = 2[(8*6)/2]+(10*10)+(10*6)+(10*8)
Answer:
To solve a quadratic equation by factoring,
Put all terms on one side of the equal sign, leaving zero on the other side.
Factor.
Set each factor equal to zero.
Solve each of these equations.
Check by inserting your answer in the original equation.
Step-by-step explanation:
So, the total area of the rectangle is just:

The area of the white rectangle is just 66 meters, so the area of the steel frame is
, and we want it to be 28 meters so: 
We don't have to consider the other root because it's obviously a negative.
