he changed the size from a tire that had a 25 inch diameter to a tire that has a 28 inch diameter. he didn’t realize this would affect his speedometer and odometer. he didn’t re-calibrate either after changing the wheel size.
how fast is he really going on the new tires when his speedometer reads 60 mph?
a. 54 mph
b. 75 mph
c. 67 mph
d. 70 mph

the answer is b.)

< 1=< 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
