In Antarctica, the air temperature is -5 degrees F. The temperature of the nearby water is 33 degrees F. How much colder is the air than the water?\

The air is 38 degrees colder.

Step-by-step explanation:

To solve for this we must understand "key words" to understand which operation we are doing. The words in this are "how much colder" this signifies we must do subtraction.

33 - (-5) = 38.

The air is 38 degrees colder.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
