The length of the other leg is 45

A^2+b^2=c^2
Plug the numbers in and square them
784+ b= 2809
-784 -784

Subtract 784 from both sides and
Take the square root of 2025 which is 45

Hope this helps!

A friend has a 82% average before the final exam for a course. That score includes everything but the final, which counts for 30
Damm [24]
So you want to set up an equation for a weighted average. You know the final is 30% of the grade, so everything else is 70%. This gives you:

(Final)(.30) + (other grades)(.70) = course grade

The best grade the student can get would be if they get a hundred on the final, since that’s the best score you can make on the final. Then,

(100)(.30) + (82)(.70) = course grade
30 + 57.4 = course grade = 87.4 Which, If you round, the student would get an 87.

For the last part, we use the same equation, just filling in different parts.

(Final)(.30) + (other grades)(.70) = course grade

This time, we don’t know the grade for the final, but we know the course grade.

(Final)(.30) + (82)(.70) = 75
(Final)(.30) + 57.4 = 75
(Final)(.30) = 17.6
Final = (17.6)/(.30)
Final = 58.667 Which is approx a 59.

Never get any closer then _____ feet when a train is passing through a railroad crossing. 25 30 15 20
nekit [7.7K]

It totally depends on speed at which train is moving.

If the speed of train is below 100 miles per hour the minimum distance maintained should be 4 feet.

If the speed of train is above 100 miles per hour and less than 125 miles per hour the minimum distance maintained should be  6.6 feet.(Approx)

As , when a train is moving with velocity more than this i.e above 125 miles per hour the minimum distance should be 15 feet.(Approximately)
