To multiply -1/3 and -5/8, we need to multiply the numerators and multiply the denominators.
(-1/3) * (-5/8)
= (-1 * -5)/(3 * 8)
= 5/24
Therefore, the correct answer is: 5 over 24.

To find Nick's hourly earnings for the job, we need to divide the total amount he earned by the number of hours he spent working.
According to the information given, we don't have the total amount Nick earned for the job. Therefore, it is not possible to determine his hourly earnings based on the given data.
The correct answer cannot be determined.
weed control $70.00
leaf removal $165.00
lawn cleanup $225.00
Aeration $90.00
Flower Planting $40.00 per flower bed
Based on the information provided, we can calculate Nick's earnings for each task as follows:
Weed control: $70.00
Leaf removal: $165.00
Lawn cleanup: $225.00
Aeration: $90.00
Flower planting: $40.00 per flower bed (3 flower beds)
Total earnings = Weed control + Leaf removal + Lawn cleanup + Aeration + Flower planting
= $70 + $165 + $225 + $90 + ($40 * 3)
= $70 + $165 + $225 + $90 + $120
= $670.00
Now, to find Nick's hourly earnings, we divide the total earnings by the number of hours he worked, which is given as 4.2 hours.
Hourly earnings = Total earnings / Hours worked
= $670.00 / 4.2
≈ $159.52
Therefore, Nick's hourly earnings for the job is approximately $159.52.
The closest option to this answer is: $159.52
