Step-by-step explanation:
0.02 is rational as it can be expressed as a finite decimal.
7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
Answer:
Rs 38,640
Step-by-step explanation:
<u>Pay attention:</u>

The principle (p) : Rs 42,000
Rate of interest (r) : 8%
Time (n) : 1 years
Exact Amount (a) : P(1-R/100)^n
Value:
A = 42,000(1 - 8/100)^1
A = 42,000(1 - 2/25)
A = (42,000 * 23)/25
A = 1,680 * 23
A = Rs 38,640
Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x
Answer:
the answer is -2.5
