Which inequality best represents that ice cream at −3°c is cooler than ice cream at 1°c? a. −3°c > 1°c b.−3°c < 1°c c. 1°c > 3°c d. 1°c < −3°c

Choice B

"ice cream at -3 degrees C is cooler than ice cream at 1 degree C"

-3 is smaller than 1

-3 < 1

Keep the order the same even though 1 > -3 is also possible, but fortunately this isn't listed.

$27.5

step-by-step explanation:

$110.00 divided by 4

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.
