Mr. Home buys two quarts of ice cream, one carton of soda, and three sacks of cookies for a Sunday School party. The respective unit prices are 60, 70, and 45 for each unit. On his way home Mr. Home remembers that he will have several extra visitors, returns to the same store, and buys three times the same order. Find Mr. Home's total expense by matrix calculations.

 Mr. Home's total expense = 1300 units

Step-by-step explanation:

Using matrix calculations

Given that

Two quarts of ice cream, one carton of soda, and three sacks of cookies will be represented as

(2, 1, 3)

The respective unit prices are 60, 70, and 45 for each unit. That is;

(60, 70, 45)

The "Dot Product" is where we multiply matching members, then sum up:

( 2, 1, 3) • ( 60, 70, 45)

= 2×60 + 1×70 + 3×45

= 120 + 70 + 135

= 325

Mr. Home returns to the same store, and buys three times the same order. That is :

3 ( 325 ) = 3×325 = 975

Mr. Home's total expense will be

325 + 975 = 1300 units

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:
