Answer:

  3 15/17 hours

Step-by-step explanation:

Sue's rate of completion is ...

  1/6 order per hour

Jim's rate of completion is ...

  1/11 order per hour

Assuming they can appropriately divide the work, their total rate of completion will be ...

  (1/6 + 1/11) = (11+6)/(66) = 17/66 . . . . order per hour

The time for one order is the inverse of that: 1/(17/66) ...

  66/17 hours per order = 3 15/17 hours per order

Working together, it will take Sue and Jim 3 15/17 hours to fill the order.

Answer:

Tax is  C 4.12

Tip is  E 15.00

total =94.10

Step-by-step explanation:

Tax = bill * tax rate

      = 74.98 * 5.5%

      = 74.98 * .055

      = 4.1239

To the nearest cent = 4.12

Tip = bill * tip rate

      = 74.98 * 20%

       = 74.98 *.2

       = 14.996

 To the nearest cent = 15.00

The total bill is

Final = bill + tax+ tip

        = 74.98 + 4.12+15

       = 94.10

Create an equation to solve for x then solve for x.
Ratling [72]

Answer:

Step-by-step explanation:

In parallelogram adjacent angles are supplementary

∠U +∠V = 180

9x + 15 + 6x + 15 = 180

Combine like terms

9x + 6x + 15 + 15 = 180

          15x + 30 = 180

Subtract 30 from both sides

          15x = 180 - 30

         15x = 150

Divide both sides by 15

            x = 150/15

x = 10

∠U = 9x + 15

      = 9*10 + 15

      = 90 + 15

∠U = 105

∠V = 6x + 15

     = 6*10 + 15

     = 60 + 15

∠V = 75
