B

Step-by-step explanation:

The chart says Jana swam 200 miles in 120 s, and Micah swam 200 meters in 104 s.

B! It's B!

Step-by-step explanation:

With A, there is a difference of 75 meters.

With C, there is a difference of 25 seconds.

With D, there is a difference of 9 seconds.

But with B, they both show they are correct!

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.
