Answer:
A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure. A description of a dilation includes the scale factor (or ratio) and the center of the dilation. The center of dilation is a fixed point in the plane.
Answer:
30
Step-by-step explanation:
triangle ABC is proportional to triangle BCD so
hypothenuse of ABC/ ajdacent of ABC = hypotrnus BCD/ ajdacent of BCD
in short
AC/BC = BC/DC
10/x = x/3
10 . 3 = x²
x² = 30
x = √30
so the question mark is 30
Answer:

Step-by-step explanation:
To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

LCM of the denominators,
2 |<u> 25 11 100 24 </u>
2 |<u> 25 11 50 12 </u>
5 |<u> 25 11 25 6 </u>
5 |<u> 5 11 5 6 </u>
<u> 1 11 1 6 </u>
LCM = 2×2×5×5×6×11 = 6600








Now we can arrange these fractions in the order of greatest to least.


The first answer is the right factors
