Which answer is the most reasonable estimation? joanne's father owns a cafe. he estimates that he uses 21 cases of eggs each week. each case has 48 eggs. about how many eggs does joanne's father use in a week? a. about 70 b. about 100 c. about 800 d. about 1,000

1000 because i just took the test if you want prove k12 right im not allowed to tell you how old i am.

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.
