Answer:
3×10^4
Step-by-step explanation:
The desired factor is found by calculating the ratio of the two numbers:
k = (9×10^2)/(3×10^-2) = (9/3)×10^(2 -(-2)) = 3×10^4
The first number is 3×10^4 = 30,000 times as much as the second number.
6 * 3 = 18 + 2 = 20
improper fraction will be 20/3
Answer:
<h2>$87.32</h2>
Step-by-step explanation:
Step one:
given data
we are told that the initial bill is $74
thereafter they gave a tip worth 18% of the bill
let us compute what 18% of $74 will amount to
Step two:
=18/100*74
=0.18*74
=$13.32
The added expenses is $13.32
Hence the total cost is
the initial bill plus the tip
=74+13.32
=$87.32
