D 15/60=h/48
D 15/60=h/48
are you sure?
I apologize for the confusion. The correct proportion that can be used to find h, the number of times Rey hit the ball with 48 at-bats, would be:
15/60 = h/48
Therefore, the correct response is:
D 15/60 = h/48
Thank you for pointing out the error.

Question
Look at the following speeds.
4 mph 8 mph 16 mph 32 mph 64 mph 128 mph
By what factor did the speeds change for each consecutive speed from the first speed to the sixth speed?
Responses
A 22
B 44
C 88
D 32
The speeds change by a factor of 2 for each consecutive speed.
4 mph x 2 = 8 mph
8 mph x 2 = 16 mph
16 mph x 2 = 32 mph
32 mph x 2 = 64 mph
64 mph x 2 = 128 mph
Therefore, the factor by which the speeds change for each consecutive speed from the first speed to the sixth speed is 2.
The closest response is:
A) 22
But the correct answer is not listed. The correct answer would be:
Factor = 2
Two 40-ounce jars of peanut butter cost $10.34. Rita wants to buy twelve 40-ounce jars of peanut butter. By what scale factor should Rita multiply $10.34 to determine the cost of 12 jars of peanut butter?
Responses
A 66
B 33
C 5.175.17
D 12
YOU BETTER GET IT RIGHT!!
To find the scale factor, we first need to determine the cost of one 40-ounce jar of peanut butter.
Two 40-ounce jars cost $10.34
Therefore, one 40-ounce jar of peanut butter costs $10.34 / 2 = $5.17
If we want to find out the cost of 12 jars of peanut butter, we can multiply the cost of one jar ($5.17) by 12.
$5.17 x 12 = $62.04
So, the correct response is:
A) 33
Therefore, Rita should multiply $10.34 by 33 to determine the cost of 12 jars of peanut butter.
