John expects to get a 3% raise and his current salary is $72,065 what will his salary be after the

8 1/4 - 6 5/6=

Step-by-step explanation:

a) When 3% of the value is added to 100% of the value, the result is 103% of the original value.

 $72,065 × 1.03 = $74,226.95 . . . . John's expected salary

__

b) 8 1/4 -6 5/6 = 8 3/12 -6 10/12

  = (8 -6) +(3/12 -10/12)

  = 2 - 7/12

  = 1 5/12

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

(a + b) (a^2 - a b + b^2)
