Mariana's salary is $31,000. juan's salary is
$28,000. at the end of each year, mariana gets a
$500 raise and juan gets a $1,000 raise. after 2
years, what will be the difference between their
salaries?
21
%

$2,000   or     6.25%

Step-by-step explanation:

1000 x 2 = 2000      

28000 + 2000 = 30000 Juan's salary after 2 years

500 x 2 = 1000          

31000 + 1000 = 32000 Mariana's salary after 2 years

30000 - 32000 = 2000 difference in salary

2000/32000 x 100= 6.25 difference in salary in percentage

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
