Which of the following could represent the scale factor of the smaller figure to the larger figure?

4:25
6pi:15pi
8:125
20pi:125pi
16pi:250pi
2:5

It could be 2:5 or 6pi:15pi

Step-by-step explanation:

If you write the ratio of the surface area as a fraction, you would get . Simplifying it would leave . But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is . The answers would be 2:5 and 6pi:15pi.

b

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
