photoshop1234 [79]

Answer:

r = 8

Step-by-step explanation:

The circumference of a circle is given by :

$C=2\pi r$ ...(1)

We need to find the value of r when C = 16π

Solving equation (1)

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{16\pi}{2\pi}\\\\r=8$

So, the value of r is 8. Hence, the correct option is (b).

Maria has a total tax of $3072 and a gross income of $60449. What is her effective tax rate (as a percent)?

Galina-37 [17]

Answer:

Effective tax rate of Maria is 5.08%.

Step-by-step explanation:

Effective tax rate ETR = $\frac{Total tax}{gross income}$

As a percent we can represent ETR = $\frac{Total tax}{Taxable income}$ ×100

In this question Maria has a total tax = $3072 and gross income = $60449

By putting these values in the formula ETR = $\frac{3072}{60449}$ ×100 = 5.08

Therefore her effective tax rate is 5.08%.
