Which of the following comparisons is false? 5° c is warmer than 5°f. 15° c is cooler than 60° f. 30° c is warmer than 90° f. 35° c is cooler than 100° f.

Step-by-step explanation:

To compare celsius and Fahrenheit temperatures, we have to convert one unit to another.

The conversion formula is

Using this let us compare one by one.

Hence C is not warmer than F

ii)

Hence C is coller than F.

ii)

N0t warmer than 100 degrees

iv)

Hence not warmer than 100 F

So only correct option is option C

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
