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.

17 units to the left of -6 on a number line.

17 units to the left of -6 on a number line is - 6 - 17 which equals to - 23.

### What is a number line?

A number line is exactly what it sounds like a horizontal, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how they should be used.

The given statement 17 units to the left of - 6 on a number line can be interpreted as,

We we'll start at - 6 on the number line, Now we know moving to the left horizontal direction in a number line results in subtraction.

Therefore,  17 units to the left of - 6 on a number line is,

= - 6 - 17.

= - 23 units from the origin which should be labeled at zero.

47 minus 3 times the difference of 15 and 2

Lets change those words to numbers
47 minus 3 times the difference of 15 and 2
47-3(15-2)
Now we have to take the order of operations into consideration.
Parenthesis
Exponents
Multiplication/Division
Lets clear out the parenthesis.
47-3(15-2)
47-3(13)=47-39=8
Therefore, the final answer is 8
