Step-by-step explanation:
Answer:(1) The distance Soo Lin walks is a function of time = True
(2) The time it takes soo- in to walk a certain distance is a function of distance = False
Step-by-step explanation:
Since the distance walked, e in miles= 3.17t
Where t is time
From the equation,
time t is an independent variable, it does not dependent on distance e
Also
distance e is a dependent variable that depend on time t
Therefore,
Distance e is a function of time t.
While time t is not a function of distance e.
The answer is B because the bill is $98 plus a 7% tax fee and 16% tip fee.
Since this is a combination not a permutation problem, (order does not matter) you should use the "n choose k" formula.
C=n!/(k!(n-k)!) where C is the number of unique combinations, n equals the total number of possible choices and k equals the specific number of choices. In this case:
C=9!/(4!(9-4)!)
C=9!/(4!5!)
C=362880/(24*120)
C=362880/2880
C=126
So there are 126 unique ways to pick 4 people from a group of 9 people.
Answer: Samira paid $8540 for her car.
Step-by-step explanation:
Let x = Amount paid by Samira for her car.
Given: Depreciation rate = 23%
Worth of car after one year = $ 6575.80
As per given,
x - 23 % of x = 6575.80
⇒ x - 0.23x = 6575.80
⇒ 0.77x= 6575.80
⇒ x= $8540 [Divide both sides by 0.77]
Hence, Samira paid $8540 for her car.
