Sumeet uses 0.4 gallons of gasoline each hour mowing lawns how much gas does he is in 4.2 hours

I believe you meant to ask how much gas does he use in 4.2 hours

we first need to calculate how much he uses in 1 minute.

60 min = 0.4 gallons

1 min =  x

where x is the amount of gallons used per minute.

we cross multiply this equation:

60 x = 0.4

x  = 0.4/60

we leave it is for now.

How many minutes are in 4.2 hours?

4 (60) + 0.2 (60) = y

where y is the number of minutes  found in 4.2 hours. So after expanding the equation we have:

240 + 12 = y

252 = y

Now we  multiply this number of minutes by the amount of gallons used for each minutes to get the total amount of fuel used.

252 * 0.4/60 = ?

100.8/60 = ?

100.8 divided by 60 = 1.68

Therefore in 4.2 hours, he uses 1.68 gallons of gasoline.

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students.   an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality.   in the case of brown v. board of education, that standard was challenged and defeated.   segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
