Answer: -1.5
Step-by-step explanation:
10000 digits can be used for 4 digit A.T.M code.
<u>Solution:</u>
Given that A.T.M required 4 digit codes using the digits 0 to 9.
Need to determine how many four digit code can be used.
We are assuming that number starting with 0 are also valid ATM codes that means 0789 , 0089 , 0006 and 0000 are also valid A.T.M codes.
Now we have four places to be filled by 0 to 9 that is 10 numbers
Also need to keep in mind that repetition is allowed in this case means if 9 is selected at thousands place than also it is available for hundreds, ones or tens place .
First digit can be selected in 10 ways that is from 0 to 9.
After selecting first digit, second digit can be selected in 10 ways that is 0 to 9 and same holds true for third and fourth digit.
So number of ways in which four digit number is created = 10 x 10 x 10 x 10 = 10000 ways
Hence 10000 digits can be used for 4 digit A.T.M code.
Answer:
13 miles
Step-by-step explanation:
Write and solve an equation involving this information, using x as the distance traveled, in miles:
Cost(x) = $6.75 = $3.50 + ($0.25/mile)x
First, subtract $3.50 from both sides, obtaining: $3.25 = ($.25/mile)x.
Next, divide both sides by $0.25/mile:
$3.25
x = ------------------ = 13 miles
$0.25/mile
The length of the taxi ride was 13 miles.
