Answer:
x = 15
Step-by-step explanation:
MN:RS
18:30
MQ:RU
Known:Known
QP:TU
15:Known
NP:ST
x:25
18/30 = x/25
30x = 18*25
30x = 450
x = 15
Radius after dilation = 4 * 1/2 = 2 in
Now, C = 2πr
C = 2π(2)
C = 4π
Or C = 4 * 3.14 = 12.56
In short, Your Answer would be 4π or 12.56 in
Hope this helps!
The answer is choice CCheck out the attached image to see the steps on how I got there.
The basic idea is to factor as much as possible. Then cancel out the common factors.
The answer is B.
Because the domain is not repeating
If you are referring to
![\frac{-1}{3} / -15](https://tex.z-dn.net/?f=%20%5Cfrac%7B-1%7D%7B3%7D%20%2F%20-15)
, these are the steps.
Remember that the denominator of -15 is 1
Do keep, change, flip for division of fractions
![\frac{-1}{3} \frac{1}{-15}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-1%7D%7B3%7D%20%20%5Cfrac%7B1%7D%7B-15%7D%20)
It'll equal 1/45 since the two negatives cancel out.
