Question 1

Bryle's sports automobile has rear tires that are 3.94 inches wider than the front ones. The width of the front tires is 10.04 inches. How many millimeters, rounded to the nearest whole number, are the rear tires' widths? There are 25.4 millimeters in 1 inch.

Accepted Answer

355 mm

Answer

First, calculate the width of the rear tires by adding the given difference (3.94 inches) to the front tire width (10.04 inches), which totals 13.98 inches. Next, convert this measurement from inches to millimeters by multiplying by the conversion factor of 25.4 mm per inch. The calculation 13.98 * 25.4 yields 355.092 mm, which rounds to 355 mm.

Question 2

A packaging band is made to fit snugly around a rubber tire's outside diameter. If the band is 213 cm long, what is the most likely size of tire it is made for? Recall the formula for circumference, C=π×D, where C is the circumference and D is the diameter. Use 3.14 for π.

Accepted Answer

68 cm

Answer

To find the tire's diameter, use the formula for circumference, C = π × D, and rearrange it to solve for D (Diameter = Circumference / π). Substitute the given circumference of 213 cm and the value of π as 3.14 into the formula. Dividing 213 by 3.14 gives approximately 67.83 cm, which is closest to 68 cm.

Question 3

In the past month, an internet retailer sold 772 green laser pointers. It anticipates that 6% of the lasers will be returned and gives a full refund of $24.99 for each laser that is returned. How much should the business anticipate refunding in total for the returned green laser pointers purchased last month?

Accepted Answer

$1,150

Answer

First, calculate the anticipated number of returned laser pointers by multiplying the total sales (772) by the return rate (6% or 0.06), which equals 46.32 returns. Then, multiply this number by the refund amount per laser ($24.99) to find the total anticipated refund. The calculation 46.32 * $24.99 results in $1157.5368, which is closest to $1,150.

Question 4

Jonah worked yesterday for 8.75 hours. 40% of his time was spent working on a marketing project. She spent the remaining time on the marketing project working on a new logo design after spending 1 hour and 15 minutes drafting ad copy. How long did Jonah spend yesterday creating the new logo?

Accepted Answer

2 hours 15 minutes

Answer

First, calculate the total time spent on the marketing project by finding 40% of Jonah's 8.75 working hours, which is 3.5 hours. Next, convert the ad copy drafting time of 1 hour and 15 minutes into decimal hours, which is 1.25 hours. Finally, subtract the ad copy time from the total marketing project time (3.5 - 1.25) to find the time spent on logo design, resulting in 2.25 hours, or 2 hours and 15 minutes.

Question 5

Ryan has purchased pavers. However, Ryan has a coupon that says, "Buy 4 pavers at the regular price and get a 5th brick for free." Each paver costs $6.19. The quantity of pavers he can buy with the coupon is unlimited. How much will it cost him overall if he uses the coupon and requires 100 pavers total?

Accepted Answer

$495.20

Answer

The coupon allows Ryan to get 5 pavers for the price of 4. To acquire 100 pavers, he needs 20 sets of 5 pavers (100 / 5 = 20). With the coupon, he only pays for 4 pavers per set, meaning he pays for 20 * 4 = 80 pavers. Therefore, the total cost will be 80 pavers multiplied by the price per paver ($6.19), which equals $495.20.
