Sort the pentagon into 5 triangles and then solve for each one
Answer:
A!
Step-by-step explanation:
It is convenient to remember that 5-12-13 is a Pythagorean triple.
Her ladder is 12 ft above the ground where it rests on the house.
_____
Using the Pythagorean theorem, you are given the hypotenuse as 13 ft and one leg as 5 ft. Then the other leg is
.. √(13^2 -5^2) = √(169 -25) = √144 = 12
Answer:
19/37
Step-by-step explanation:
The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor
Total number of people in the faculty =
9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors
= 37 people
Hence,
The probability of choosing a professor or an instructor
= P( Professor) + P( Instructor)
= 9/37 + 10/37
= 19/37
