Tiana is a princess who had a vision for her life and with courage and a willingness to take risks for her goal, she accomplished them. Last year, Tiana earned $155,555 as a restaurateur in New Orleans, Louisiana. She is married and claims 3 dependents; she paid $5,512.09 in state income taxes last year. What is the state income tax rate in Louisiana?

3.5435%

Step-by-step explanation:

Tiana's earnings = $155,555

State income tax paid = $5512.09

The State income tax rate will be calculated as:

State income tax/Tiana's earnings × 100%

= $5512.09/$155555 × 100%

= 0.035435 × 100%

= 3.5435%

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
