Ike Phillips worked 6.7 hours at time-and-a-half pay and 3.4
ikadub [295]

Working out the different pay rates earned by Ike Phillips :

  • Time and half pay rate = $17.055
  • Double pay rate = $22.74
  • Time and half earning = $114.2685
  • Double rate earning = $77.316
  • Gross earning = $646.3845

Let :

Regular rate = $11.37

Total earning for the week = $454.80

Double pay hours = 3.4

Time and half pay hours = 6.7

  • Time and half pay rate = 1.5 × regular pay rate = 1.5 × 11.37 = $17.055

  • Double pay rate = 2 × regular pay rate = 2 × 11.37 = $22.74

  • Time and half earning = rate × time = $17.055 × 6.7 = $114.2685

  • Double rate earning = rate × time = $22.74 × 3.4 = $77.316

  • Gross earning = (regular + time and half + double earning) = $(454.80+114.2685+77.316) = $646.3845

Therefore, Ike's gross earning for the week is $646.3845

PLS HELP WILL GET BRAINLIEST
Tatiana [17]

Step-by-step explanation:

just look at the objects !

they are completely regular, and each arm can cover every other other arm.

so,

15A needs 1/3 of a full rotation.

15B needs 1/2 of a full rotation.

15C needs 1/4 of a full rotation.

15D needs (can you guess ?) ... 1/6 of a full rotation.

Ill give you brainliest>>>Write an equation of the line passing through the point (5, 2) that is perpendicular to the l
11Alexandr11 [23.1K]

y= mx+b

(16, -7) = (x,y)

2(16) - 3y = 12

32 - 3y = 12

32 - 12 = 3y

20/3 = y

6.6 = y

2x-3(-7) = 12

2x+21 = 12

2x = 12 - 21

x = -9/2

Insert the values into y = mx + b

solve for m and then solve for b
