Charles can walk 1/2 of a mile in 9 minutes. How much of a mile does he walk in 1 minute?, I am hanging Christmas decorations. I have 20 feet of garland. If I add a bow every 1/4 of a foot, how many bows will I have on my garland?, My usual snickerdoodle recipe calls for 3/4 cup of brown sugar. I am only making half of the recipe. How much brown sugar should I use?

since half a mile is 2640 feet and he walked that in 9 minutes sooo uhm- (im brain storming it might not even be right) so if you divide 2640 divided by 9 you get 293, so most likely charles walked 293 feet each minute?

i think you will have 5 garlands

i believe you would use 1.5 cup of brown sugar

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.
