If you would like to know how long would it take John to mow the lawn alone, you can calculate this using the following steps:
hours (Jessica) ... a
hours (John) ... b = ?
a + b = 11
b = 4 * a
___________
a + b = 11
a + 4 * a = 11
5 * a = 11 /5
a = 11/5 = 2 1/5 = 2.2 hours
b = 4 * a = 4 * 2.2 = 8.8 hours
The correct result would be 8.8 hours.
Answer:
8.760 x 10^3
Step-by-step explanation:
There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.
Hope this helps! :)
