X = Amount paid one hour
205.25 - 59 = 146.25
3.25x = 146.25
x = 146.25 ÷ 3.25
x= 45
Answer:
–7 is not the arithmetic square root of 49 only in case we are taking it for natural number.
Step-by-step explanation:
- The square root of x is that number which on squaring gives the result as x.
- For example, the square root of 4 is +2 or -2. Because on squaring +2 or -2 we get the number 4.
- Similarly for the case of 49, the square root might be both +7 or -7.
- But if we are taking it as a natural number then -7 is not valid. Like for length, quantity or other sort of things -7 is not the arithmetic square root of 49.
Answer:
A. -500
Step-by-step explanation:
Find the slope using rise over run (change in y / change in x)
Find the change in the y values (height of the plane):
24,000 - 18,000
= 6,000
Find the change in the x values (miles from the airport)
(60 - 72)
= -12
Divide 6000 by -12:
6000/-12
= -500
So, the slope of the plane's path is A. -500
