Brigit's class is collecting cans for recycling. Their goal is to collect 750 cans. The first month, they collect 459 cans.
The next month, they collect 216 cans.
Use the drop-down menus to answer the questions below.
CLEAR
An expression that models the number of cans remaining to collect is 750 - (459 +216)
Frederick's class is also collecting cans. The number of cans they still have to collect equals 675 - (325+190). A possible series
of events that led to these remaining cans is:
1.
2.
3.

step-by-step explanation:

b and c

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.

the answer is 99.
