Three men (Greg, Larry, and Sam) went to the pet shop on different days (Monday, Wednesday, and Friday) and each bought a different breed of dog (German Shepherd, Labrador Retriever and Saint Bernard). From the clues below, which chart correctly matches the man, the day and the dog breed? 1. No man purchased a breed of dog beginning with the same letter as their first name.
2. Greg purchased the St. Bernard before Sam purchased his dog.
3. The German Shepherd was the first dog to be purchased.

Step-by-step explanation:

its b i just took the test hope this helps

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.
