Rosalyn worked 44 hr one week and earned a $989 paycheck. she earnsnbsptime and a half (1.5 times her regular hourly wage) for the number of hours she works in excess of 40. what is rosalyn? s regular hourly wage?

Solution:

Rosalyn earned = $989 in 44 hour

Excess work = 44 - 40 = 4

Let the regular hourly wage = $x /hour

Overtime hourly wages = $1.5x/hour

40x + 4($1.5x) = $989

40x + 6x = $989

46x = $989

x = 21.5

Hence, Rosalyn's regular hourly wages is $21.5.

inverse operation of addition

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
