Answers
Answer 1
Answer:
To figure out which airline provides more reliable service, we need to figure out what ABC Airlines's delays are in percents.
To get that, we need to reduce 18/126 by 2.
When we reduce both the numerator and the denominator we get 9/63.
Now, we cannot reduce that again, without getting a decimal for the numerator/denominator.
So, now that we know that the fraction is 9/63, we divide it, and we get : 0.142857
Changing that into a percent, we get 14%.
14% is the percent that ABC Airlines has delays. DEF Airlines has delays of 13% in recent flights.
So, from that, we can conclude that DEF gives more reliable service.
The percentage of any number can be found by the method described below. It always has to be remembered that any percentage given can be determined by multiplying the percentage number with the number from which the percentage has to be determined. 12% of 72 = (12/100) * 72 = 0.12 * 72 = 8.64 8.64 is 12% of 72. Determiningany kind of percentage will not be a challenge for anybody if the aboveprocedure is followed step by step.

now the other diagonal 11^2+5^2=c^2 121+25=c^2 146=c^2 sqrt both sides12.083 closest is B
