Question 6

Fifteen boxes each containing 8 radios can be repacked in 10 larger boxes each containing how many radios?

Accepted Answer

Initially, there are 15 boxes each containing 8 radios, totaling 15 * 8 = 120 radios. To fit these into 10 larger boxes, each box must contain 120 / 10 = 12 radios.

Question 7

Consider the statement "If n is an even number, then n is two times an odd number." For which of the following values of n is the statement FALSE?

Accepted Answer

The statement is false for n = 8 because 8 is not two times an odd number; it is two times 4, which is even.

Question 8

Question 16

Which of the following ordered pairs (x, y) is a solution to the equation 2x - 3y = 6?

Accepted Answer

Plugging the values from option B (3, 0) into the equation 2x - 3y = 6 gives 2(3) - 3(0) = 6, which simplifies to 6 = 6, confirming it as a solution.

Question 17

A plumber charges customers $48 for each hour worked plus an additional $9 for travel. If h represents the number of hours worked, which of the following expressions could be used to calculate the plumber's total charge in dollars?

Accepted Answer

The total charge is calculated by multiplying the hourly rate ($48) by the number of hours worked (h) and then adding the travel charge ($9). This is represented by the expression (48 x h) + 9.

Question 18

Of the following, which is closest in value to 0.52?

Accepted Answer

1/2 is equal to 0.5, which is the closest value to 0.52 among the given options.
