One day, Rocket Boy flew 23 times the distance automan travelled in his car. If Rocket Boy flew 9936 km, what was the total distance thy covered

Answers

If you would like to know what was the total distance they covered, you can calculate this using the following few steps:

9936 km / 23 times = 9936 / 23 = 432 km (the distance of the car)

the total distance: 9936 km + 432 km = 10368 km

The correct result would be 10368 km.
To find out the car's distance divide 9936 by 23, which equals 432, so 432km is how far the car drove.
Adding 432 and 9936 gives you the total distance covered, which is 10368km. 

Kariz Johnson earns 34850 annually as an engineer. She is single and supports her father. The state tax rate in her state is 3% of taxable income. What amount is withheld yearly for state income tax?

Answers

Answer:

The amount withheld yearly for state income tax is 1045.50

Step-by-step explanation:

Kariz Johnson earns 34850 annually as an engineer.

Suppose, the amount of yearly state income tax is  x

The state tax rate in her state is 3% of taxable income. That means, if the taxable income is 100, then the amount of tax is 3.

So, according to the ratio of "amount of tax" and "amount of income" , the equation will be......

(x)/(34850)= (3)/(100) \n \n 100x=34850*3=104550\n \n x=(104550)/(100)=1045.50

Thus, the amount withheld yearly for state income tax is 1045.50
