35. Think About a Plan The United States has a land area of about 3,536,278 mi?. Illinois has a land area of about 57,918 mi?.
What is the probability that a location
in the United States chosen at random is not in Illinois? Give your answer to the
nearest tenth of a percent.
• How can you solve this problem using the complement of an event?
• How do you write a fraction as a percent?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer is c

step-by-step explanation:

81/12=324/x

x=48
