Answer:

18.8496 units (rounded o1ff to four decimal places)

Step-by-step explanation:

Arc length = 2 × π × r × \frac{central-angle}{360}

r (radius) = 12 units ÷ 2 = 6 units

Central angle = 180°

For our semicircle, the arc length = 2 × π × 6 × \frac{180}{360} = 18.8495559215 units

Or 18.8496 units (rounded o1ff to four decimal places)

In the diagram below, which distances would need to be the same in order for point A to be on the bisector of angle W? Explain w
Pachacha [2.7K]

Answer:

PA = XA

Step-by-step explanation:

Construction of an angle bisector,

1). Mark an arc from point W with the help of a compass which intersect lines WS and WZ at the points P and X respectively.

2). Marc two arcs of the same length form the points P and X which intersect each other at a point A.

3). Joint the points A and W.

Thus AW will be the angle bisector of angle PWX where PA = XA.

Therefore, distances PA and XA will be equal in measure.

Whitney contributes 13% of her $70,600 annual salary to her 401(k) plan.
Licemer1 [7]

<u>Answer: </u>

option (B) $61,422

<u>Explanation:</u>

Given the annual salary is $70,600

Percent of Contribution made from the income = 13%

Pretax Salary/Income is calculated by the formula, Salary – 13% of salary

Pretax income =

70600 - \frac{13}{100} \times 70600

= 70600 – 9178 = 61422

Therefore whitney’s pretax income is $ 61422

Hence, option (B) is correct
