Answer:
The length of segment AC is two times the length of segment A'C'
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ----> the scale factor
A'C' ----> the length of segment A'C'
AC ----> the length of segment AC
so
we have that
---> the dilation is a reduction, because the scale factor is less than 1 and greater than zero
substitute
therefore
The length of segment AC is two times the length of segment A'C'
Step-by-step explanation:
What this is saying is...20 is a whole number; but 3/4 is not. What they are saying is, if you have to add a mixed number with a whole number, you can add both of the whole numbers together. Then, you add the 3/4 at the end...because it is not a whole number. You can break apart a mixed number by separating the whole number and the fraction.
Hope this helps :)
You are right. In circle equation we have =r² so the correct answer will be C od D. But we have to calculate the center of a circle.
Complete the square:
And we have:
So the answer is C (the same left side of equation).
The answer is -7! hope this helps
First you convert centimeters to meters which will be 35 centimeters-> 0.35 meters
Once you have that, you multiply String A's length (0.35 m) by 5 to find String B's length which will be 1.75 meters.
Now that you have the two lengths you multiply each by 17.
17 x 1.75 = 29.75 and 17 x 0.35 = 5.95
Now you just add 29.75 and 5.95 and you get your answer which is
35.7 meters
