B can finish the job alone in 24 days.
In work-rate problems, a certain person can complete a fraction of the job for a specific timeframe. As stated in the problem, A and B can finish the job by working together for 8 days. It must be noted that the fraction of the job they can finish individually per day is additive.
A can complete the work in 12 days and finish 1/12 fraction of a job per day. This can be substituted directly to the equation to solve for the time B needed to finish the work.
This means that B can do 1/24 fraction of the job per day and can completely finish the job in 24 days.

Answer:
Step-by-step explanation:
In this case, the example is missing the negative sign.
This is an example of scientific notation, which is used to reduce a very large number into a short expression like: 0.000000005, which is reduced in the expression .
It's important to say that the negative sing in the exponent, indicates that all zeros that are being reduce, are placed at the right of the number. Also, to apply a correctly scientific notation, the number reduced should be between 0 and 10.
Answer:
1) 100 ) 15
Step-by-step explanation:
1) 30 to 50 is 20 miles so 5 * 20 is 100
2)20 to 50 is 30 miles so its 150 and 15 to 20 is 5 so 11 *5 is 55
55+150 equals 250 so the answer is 15 miles.
Formula for perimeter a+b+a+b
12+5+12+5= 17+17= 34 .34=P
