Catie earned $3,511.95 last month. She used 3/5 of her earnings to pay her bills. With the remaining money she bought two skirts
andrew11 [14]

Answer:

Amount \ left = 1345.81

Step-by-step explanation:

Total  \  earning = T= $3,511.95

Spent \ on \  Bills = B = \frac{3}{5} T = 2107.17

Remaining  \ amount = R = T-B = $3,511.95 - 2107.17\\R = 1404.78

Spent \ on \ Shopping = S = 2($21.99) + $14.99\\S = 58.97

Amount \ left = L = R - S\\Amount \ left = 1404.78 - 58.97\\Amount \ left = 1345.81

A circle with area 100π has a sector with a central angle of 2/5π radians.
Snowcat [4.5K]

Answer:

  20π square units

Step-by-step explanation:

The sector area is found using the proportion ...

  sector area / circle area = sector angle / whole circle angle

Multiplying by "circle area", we get ...

  sector area = (circle area)( sector angle / whole circle angle)

  = (100π)(2/5π)/(2π)

  = (100π)(1/5)

  sector area = 20π
