Answer:
1/3
Step-by-step explanation:
The number of people over 40 is 20 + 30 + 35 = 85.
So the probability is 85/255, which reduces to 1/3.
Answer:
36.1 meters
Step-by-step explanation:
Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.
I'll choose to look at the bottom triangle in this case
30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.
20 is A, 30 is B, and the missing side is C

C, the missing side to the nearest tenth is 36.1 meters
Answer:
1.12 x 10^6 or 1,120,000
Step-by-step explanation:
You work out the first part which would be (3.76 x 10^5) or 376,000.
Then you work out the second part which would be (7.44 x 10^5) or 744,000.
Then you add them together and move the decimal over to where the number is less than ten but greater than 0 so it would be like this:
1.120000
But just cut all the zeros so it would be like this:
1.12
And how ever many times you move the decimal over is the number you put beside the ten by the way. it should look a little like this by the time you are done:
1.12 x 10^6
x² - 20x + 91
x -13
x -7
your answer is (x - 13) (x - 7)
hope this helps
