For the first part of this question, you will write the following division problem to represent this situation:

(122 + 11)/16 =
133/16 =8.3125

Mrs. Reyes is NOT correct! You will need one more bus because 8 groups of 16 is 128, and you need to fit 133 people on the buses.

To show the place value models, you will need 4 individual boxes, 3 rows of 10 (30), 5 - 10 x 10 models (500) and 1 cube that is 10 x 10 x 10 (1000).

1000 + 500 + 30 + 4

What type of graph are you most likely to use if you are comparing 2 quantitative continuous variables.
givi [52]
The answer would be a histogram. It is an accurate display of numerical data. It shows the basic frequency distribution or shape of a data. We know that continuous data are measured on a scale or continuum (for example: weight or test scores). Histograms are useful for displaying continuous data.

Which of the following expressions is correct? Select one: a. marginal cost = (change in quantity of output)/(change in total co
Natasha_Volkova [10]

Answer:

b. average total cost = total cost/quantity of output

Step-by-step explanation:

The marginal cost is the additional cost of producing one more unit of output and it can be calculated by taking the change in total cost and dividing it by the change in quantity, its formula is:

  • <em>Marginal cost = change in total cost/ change in quantity</em>

The average total cost (sometimes referred to simply as average cost) is total cost divided by the quantity of output, its formula is:

  • <u><em>Average total cost = total cost / quantity of output</em></u>

The total cost is obtained adding together the fixed costs and the variable costs, its formula is:

  • <em>Total cost = fixed cost + variable cost</em>

The average variable cost is obtained when variable cost is divided by quantity of output, its formula is:

  • <em>Average variable = variable cost / quantity of output</em>

I hope you find this information useful and interesting! Good luck!

Please can someone help me?

If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm

(3 × 14) + 38
42 + 38 = 80 cm

So the perimeter would be 80 cm.
I hope this helps!
