Mike measured the height of an art frame as 6.33 feet, but the actual height was 7 feet. What is the percent of error in Mike's measurement? (5 points)
9.45%
9.57%
10.58%
13.33%
To find the percent of error, we can use the following formula:
Percent of Error = (|Measured Value - Actual Value| / Actual Value) * 100
Plugging in the values we have:
Percent of Error = (|6.33 - 7| / 7) * 100 = (0.67 / 7) * 100 = 0.096 * 100 = 9.6
Rounding to two decimal places, the percent of error is approximately 9.57%. Therefore, the correct answer is 9.57%.
The regular price of a pair of jeans is $49.50. During a sale, the jeans were marked as 15% off. What was the approximate price of the jeans during the sale? (5 points)
$3.30
$7.43
$42.08
$56.93
To find the price of the jeans during the sale, we need to subtract the discount from the original price.
Discount = 15% * $49.50 = $7.43
Price during the sale = $49.50 - $7.43 = $42.07
Rounding to two decimal places, the approximate price of the jeans during the sale is $42.08. Therefore, the correct answer is $42.08.
