Vincent and Irma agreed to babysit their sister for 3 hours while their parents were at a play. Vincent went first, while Irma did her homework. Then Irma watched her sister so Vincent could do his. In the end, Vincent and Irma watched their sister for the same amount of time. How long did each sibling watch their sister?

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.

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
