Answer:
40%
Step-by-step explanation:
Original price = x
Sale = 20% off
20% / 100 = 0.2 to convert from a percent to a decimal
Sale = x - 20% of x = x - 0.2x = 0.8x
Sale price = y = 0.8x
Reduction of sale prices = 25% = 0.25
Reduction = y - 25% of y = y - 0.25y = 0.75y
End price in terms of original price (x):
0.75y = 0.75(0.8)x
= 0.6x
End price = 0.6 or 60% of original price, coming out to a 100-60 = 40% overall percentage reduction
Answer:
Time (week 1 - week 10)
Step-by-step explanation:
Given
Measure of cost of gasoline over a period of time
Required
Determine what variable belongs to the horizontal axis
To answer this question, I'll re-echo the given parameters again
Measure of cost of gasoline over a period of time
This can be rephrased to be
Measure of cost of gasoline with respect to time
This means that the cost of gasoline is a function of time (10 weeks, to be precise).
Hence;
<em>Cost will be on the vertical axis</em>
<em>Time will be on the horizontal axis</em>
<em />
<em>Conclusively,</em>
<em>The first option answers the question</em>
<em />
S=d/t
S=speed
d=distance=150 Km=150 Km*(1000 m/1Km)=150,000 m
t=time=7200 s
S=150,000 m/7,200 s=20.83 m/s.
Solution: S=20.83 m/s.
