Problems 1-4 show numbers rewritten in exponential notation. the missing powers of 10 are represented by letters.

type the powers into the boxes that correspond to each letter. use a slash (/) to show a fraction. use a caret (^) before an exponent. do not add any spaces. for example, to show \frac{1}{10^2}, type 1/10^2.

2.247 = 2 x a + 2 x b + 4 x c + 7 x d

a = answer

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

mean, 40.6

step-by-step explanation:

27 +27 or 27times 2=54

the diffrence is 0
