CAN U HELP I WILL GIVE 20 POINTS

Your pay rate would be $7 per hour

Your friend's rate is $9 per hour

Step-by-step explanation:

To get the answer for your pay rate you'll have to divide 56/8 and then you'd  get your number 7, so you get $7 dollars per hour.

To get the number for your friends pay rate you'd also do the same thing, divide. 36/4 gives you the number 9, so your friend gets $9 dollars per hour.

~PLZ give brainliest only if this is correct, thx!~

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.
