5. A filter apparatus is submerged in fish tank A, raising the water
level 1 cm. When the same filter is submerged in fish tank B,
the water level is raised only 0.5 cm. If the fish tanks have the
same water level without a filter, what is the ratio of the area
of the water surface of tank A to the area of the water surface
of tank B?

step-by-step explanation:

answer: 20

step-by-step explanation:

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
