Mary put in a total of 16 1/2 hours mowing lawns during 5 days the past week. How long was her average work day?

Answer:

Step-by-step explanation:

To find x, set the two expressions equal and solve:

8x + 11 = 12x - 1

11 = 4x - 1

12 = 4x

x = 3

Answer

Length measured with Ruler A= 1.17 dm

Length measured with Ruler B= 1.18 dm

Step-by-step explanation:

I included a missing image that shows the pencil's length as measured using two rulers.

Ruler A has a scale marked at 1 dm intervals.

Ruler B has a scale marked at 0.1 dm intervals.

Length measured with Ruler A= 1.17 dm

(The middle markings reveal that the pencil tip lies between 1 and 1.25, slightly above 1.125 but below 1.25, positioning it around 1.2 and 1.125 dm, approximately half of 1.25, which is 1.125, plus an increment of one of the three halves of that half, which gives 1.125+0.045 dm thus concluding to 1.17 dm.)

Length measured with Ruler B= 1.18 dm

(The pencil tip appears just shy of 1.2 dm, confirming the precise value is clearly 1.18 and not 1.19 dm.)

Tip: When unsure about the exact measure, it’s advisable to estimate one extra decimal beyond what the ruler presents.

In the context of science, the rate is defined as a <span>metric that is evaluated in relation to another measured metric. To determine the rate for each set of data, we calculate the slope. The calculations proceed as follows:

Megan's growth rate = (12 - 4.5) / (4 - 1) = 2.5 inches weekly
Suzanne's growth rate = (11 - 5) / (4 - 1) = 0.5 inches weekly

Thus, it's clear that Megan’s plant grew more rapidly at a rate of </span><span>2.5 inches each week.</span>

Answer:black

Step-by-step explanation:

A single rose sells for 50 cents, so buying two will cost $1 (50 cents multiplied by 2).

With 2 roses per dollar, spending $20 allows for the purchase of 40 roses.

They make $6 profit on $20 sales, which means they spend $14 on the 40 roses ($20 minus $6).

Dividing $14 by 40 roses gives a cost of $0.35 per rose.

Therefore, the vendor pays 35 cents for each rose.
