An ant can travel at a constant speed of 980 inches every 5 minutes. 1. How far does the ant travel in 1 minute?
2. At this rate ,how far can the ant travel in 7 minutes?

196 per minute, 1,372 per 7 min

Step-by-step explanation:

980/5=196

196*7=1,372

good luck on your studies! : )

david edward.

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.
