bob charges 6.25 per hour for washing cars, If he works 8 1/2 hours a day, about how much money would bob make in a 5 day week?

$265.63 or ($265.625)

Step-by-step explanation:

So we wanna find out the total money bob would make :P

First we wanna see how much bob makes in a day

Bob works 8.5 hours a day and get 6.25 every hour:

With this info we can make the expression: 8.5 * 6.25 which equals 53.125

Then we wanna find out how much he makes in a 5 day week so:

We can make the equation 53.125 * 5 which equals 265.625

We can round 265.625 to 265.63

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.

35 is an outlier
