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 the product of -5, -10, and 12, we need to multiply them together.

-5 * -10 * 12

= 50 * 12

= 600

Therefore, the correct answer is: 600.

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.
Answered by GPT 3.5
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

To find the change in Devon's account each month after paying for the service, we need to divide the total payment by the number of months.

Total payment: $936
Number of months: 8

Change in account each month = Total payment / Number of months
= $936 / 8
= $117

Therefore, the correct answer is: $117.

For the second question, it is stated that Alexander's height increased by 108 inches over 6 minutes, and it increased by the same amount each minute. Therefore, to find the effect on Alexander's height each minute, we divide the total increase by the number of minutes.

Total increase: 108 inches
Number of minutes: 6

Effect on height each minute = Total increase / Number of minutes
= 108 inches / 6
= 18 inches

Therefore, the correct answer is: 18 inches.

To find the product of -4/7 and -11/2, we need to multiply the numerators and multiply the denominators.

(-4/7) * (-11/2)

= (-4 * -11)/(7 * 2)

= 44/14

Simplifying this fraction further, we can divide both the numerator and denominator by their greatest common divisor, which is 2.

44/14 = (2 * 22) / (2 * 7) = 22/7

Therefore, the correct answer is: 22/7.

To find the product of 9, -3/7, and -1/3, we need to multiply them together.

9 * (-3/7) * (-1/3)

First, let's simplify the expression by canceling out common factors:

= 9 * (-1) * (-1)
= 9

Therefore, the correct answer is: 9.
Answered by GPT 3.5
You're right, I apologize for the oversight. Let's redo the calculation correctly:

To find the product of 9, -3/7, and -1/3, we need to multiply them together.

9 * (-3/7) * (-1/3)

= -27/7 * (-1/3)

When multiplying fractions, we simply multiply the numerators and denominators:

= (27 * 1) / (7 * 3)
= 27/21

Simplifying the fraction further, we can divide both the numerator and denominator by their greatest common divisor, which is 3:

= 9/7

Therefore, the correct answer is: 9/7.
