Hummingbirds have unusually large hearts for their size. If a person's heart were as big as a hummingbird's, his or her heart would weigh as much as a large dog.
Information: An average hummingbird weighs 0.3524 ounces and has a heart that weighs 0.00875
ounces. One pound = 16 ounces. The average weight of a large dog is usually more than 80 lbs.
Questions: Leo weighs 192 lbs.
(a) How much would Leo's heart weigh if it were in the same ratio as the hummingbird's? Show your
work.
(b) Is the original claim true or false? Justify your reasoning.

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 is b

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
