Plz show work and try to get it correct! !

during two years, the population of birds of an island become 7 times more than before. if the first year increase in the population was 40%, what was the percent increase of the second year?

400%

Step-by-step explanation:

Let the initial population be 100.

In 2 years, it becomes 7 times, that would be:

100 * 7 = 700

1st year, the increase is 40%, that is:

40/100 = 0.4

0.4 * 100 = 40

After increase it becomes: 100 + 40 = 140

So, in 2nd year it will become 700 from 140. How much percentage increase is that??

That would be the increased amount (700 - 140 = 560) divided by the 1st year amount (140). Multiply that by 100 to get the percentage. Shown below:

700 - 140 = 560

Now,

560/140 = 4

4 * 100 = 400%

So, the percent increase of second year is 400%

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

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:
