Answer:
Answer D: 8.7 cm
Step-by-step explanation:
First compare the actual diameters of both cables to find out which one is larger. If we write both diameters in fraction form (as they are given), we need to have them expressed with the same denominator for a straight forward comparison:
Bundle A: 
Bundle B: 
So we multiply this last fraction by 2 in numerator and denominator to obtain the same denominator as for Bundle A without actually changing its numerical value: 
So now we compare Bundle A with bundle B, and see that bundle B has the larger diameter: 22/8 inches
The hole has to be 25% larger than this larger diameter, so we estimate 25% of 22/8 in is:
inches
Therefore, the hole must be of diameter 22/8 in plus 0.6875 in = 3.4375 in
Now we convert this value into centimeters by multiplying it by 2.54 (since one inch is 2.54 cm):
3.4375 * 2.54 = 8.73125 cm
which rounded to the nearest tenth as requested in the problem is: 8.7 cm

=-6 =9
-6×9= -54
Answer:
c, d
Step-by-step explanation:
a) There are more cars than bike so it should be the opposite for 10th grade students. Therefore, this choice is wrong.
b) There are more cars than any other choice for 11th graders. Therefore, it should be more than 1/2 of the 11th grade students travel by car not less than.
c) In 11th grade, 27 people ride bikes. In 9th grade, 20 people ride bikes. Therefore, more people from 11th grade are more likely to travel by bike. This means this option is correct.
d) 139 students are in 11th grade, 51 students are on 9th grade, 46 students are in 10th grade, and 44 students are in 12th grades. Because there are more students in 11th grade than any other grade, this option is also correct.
