Answer:
h = 16 feet
Step-by-step explanation:
Pythagoras´ theorem establishes, that in a right triangle square of the hypothenuse (c²) is the sum of leg ( b²) plus leg (a²)
Then
c² = a² + b²
where according to the problem statement
(20)² = h² + (12)² ( h is the height of the flagpole )
h² = 400 - 144
h² = 256
h = √ 256
h = 16 feet
12 would be the y intercept because x is 0 and y is 12
Answer:
A -1/2
b 3/-4
C -1/-5
Step-by-step explanation:
Ou paint 1/3 of a wall in 1/4 hour. At that rate, how long will it take you to paint one wall? rate = (area/time)
------
rate = (1/3)/(1/4) = 4/3 job/hr
-----
time for job = 3/4 hr/job = 45 minutes to do the whole job.
