Started 35 feet under water, jumped up and out of the ayer to 27 ft into the air, and then returned to the water, dived 18 ft then dawn 16feet directly towards the shoreline. WHAT IS THE TOTAL VERTICAL DISTANCE THE DOLPHINS TRAVELED?

The dolphins travled a vertical distance of 53 feet  

Step-by-step explanation:

35-27=8

27+8=35

35+18+=53

You don't include the 16 feet because that is going towards the shoreline horizontally.

SORRY IF IM WRONG.

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.
