The total distance an ant crawls varies directly with the time in seconds. The ant crawls a total distance of 168 centimeters in 12 seconds. What is the time in seconds the ant crawls when the total distance is 350 centimeters?

14 s

24 s

25 s

29 s

25

Step-by-step explanation:

14 x 25 gives you 350

25 is the answer for people that are in k12

triangle and cube

step-by-step explanation:

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.
