There are 15 questions on the test and the students have been given 55 minutes to complete it. A Table titled Test Time, showing Number of Questions, Time per Item in minutes, and Total Time in minutes. The first row shows Multiple Choice, with m, 3, and 3 m. The second row shows Free Response, with 15 minus m, 8, and x. The third row shows Total, with 15, blank, and 55. Which value could replace x in the table? 7 – m 23 – m 8(15 – m) 8(15) – m

Answer:

<h2>8(15-m)</h2>

Step-by-step explanation:

In the table, <em>x </em> represents the total time students take to respond free-response question. So, the replacement of the variable must be the product between the number of free-response questions and the time per questions students take.

Number of free-response questions: 15-m

Time per Item (minutes): 8

Therefore the product would be: 8(15-m), which is the expression that must replace <em>x.</em>

The radius of the wheel of a bicycle is 14 inches. What is the distance that the bicycle covers after ten rotations? Use
ivolga24 [154]

Distance covered in 1 rotation = circumference of the wheel

                                                  = 2\pir

                                                  = 2 x \frac{22}{7} x 14

                                                  = 2 x 22 x 2

                                                  = 88 inches

Distance covered in 10 rotations = 88 x 10 = 880 inches

Therefore, the bike covers 880 inches after 10 rotations.

A recipe for brownies calls for 1/8 cup of sugar and the recipe makes 12 brownies what fraction of a cup is in each brownie? THA
denis23 [38]

Answer: \frac{1}{96}

Step-by-step explanation:

(\frac{1}{8})/12

Divide the fraction \frac{1}{8} by 12. This is because we need to split the sugar between 12 brownies, and to split something means to divide it. Use the switch, flip and multiply method.

I inserted an image on how to use this method.

Anyway, to use this method, we need 2 fractions, so instead of 12, we have to use \frac{12}{1}.

\frac{1}{8}/\frac{12}{1}

= \frac{1}{8} × \frac{1}{12}      Multiply the denominators and numerators

= \frac{1}{96}
