A group of students and workers entering a metro station were asked whether they were riding the bus or the subway. The two-way
BaLLatris [955]
Because this is a two-way table, the answer would be that 166 people were polled in total. Why? Well, there are lots of corresponding patterns leading up to this answer. We can easily find the answer by looking at the problem two different ways:

1st way: Identifying the missing solution by rows.

27 + 21 = 48 and 42 + 76 = 118, so we can find the missing value by adding 69 and 97 to get 166.

2nd way: Identifying the missing solution by columns.

27 + 42 = 69 and 21 + 76 = 97, so we can find the missing value by adding 48 and 118 to get 166, our missing solution.

Your final answer: 166 people were polled. Your answer would be D. If you need to better understand this, let me know and I will gladly assist you.

A gift box is 14 inches long, 8 inches wide, and 4 inches high. How much wrapping paper is needed to wrap the gift box?
Mazyrski [523]
We will use the formula for finding the surface area of a rectangular prism. 

Formula = 

SA <span>= </span><span>2 </span><span>(</span><span>w</span><span>l</span><span>+</span><span>h</span><span>l</span><span>+</span><span>h</span><span>w</span><span>)</span>SA = 2 (8·14 + 4·14 + 4·8)
SA = 2 (112 + 56 + 32)
SA = 2 (200)
SA = 400

The gift box needs C) 400 in wrapping paper to wrap the gift box. <span />

Complete the table of values below so that it represents a line with a constant rate of change of `-\frac{3}{4}.`
Nady [450]

To find values of the table, plug in the given corresponding values of x or y, and constant rate of change (m) = -3/4 into y = mx.

<h3>What is the Constant Rate of Change?</h3>

Constant rate of change of any table or function is a comparison of how two variables are changing, which can be determined using the formula, m = change in y/change in x = \frac{y_2 - y_1}{x_2 - x_1}.

Where x and y are the coordinates of a table or functions, and m is the constant rate of change, the equation that models the relationship would be, y = mx.

The image of the table is missing, however, to complete the given table, plug in any of the given values of x or y, and constant rate of change (m) = -3/4 into y = mx.

Find the original cost of a rocker selling for $159.95 at 20% off
Alinara [238K]
The original price is $199.94

Given:
Discounted price = 159.95
Discount rate = 20%

If the discount rate is 20%, then the price is equivalent to 80%.

To get the original price, simply divide the discount price by its corresponding percentage.

Original price = 159.95 ÷ 80% = 199.94

To check
199.94 * 20% = 39.99   * value of the discount
199.94 - 39.99 = 159.95  *discounted price
