If a circle is dilated by a scale factor of

Mathematics

Answer/Step-by-step explanation:

The scale factor is missing in the question. However, here's how to find the length of the new radius if given a known scale factor.

Length of new radius = length of the radius of the dilated circle × scale factor of dilation

Length of the radius of the dilated circle is given as 18m

Therefore,

Length of new radius = 18m × scale factor.

If the scale factor is a fraction, it means the new length would be smaller than 18m. But if the scale factor is a whole number, the new length of the radius would be greater than 18m.

Let's assume any of the following scale factors was what was given in the question:

<em>*If scale factor given is ½, new radius length = 18m × ½ = 9m</em>

<em>*If scale factor given is 2, new radius length = 18m × 2 = 36m</em>

Milo cut his cake into 2 equal pieces. He ate 2pieces of cake for his birthday.

Sauron [17]

Answer:

$1$ $or \frac{2}{2}$

Step-by-step explanation:

<h2><u>We know that Milo cut his cake into 2 different pieces, so:</u></h2>

$\frac{x}{2}$

<h2><u>He then eats two pieces of the cake. so:</u></h2>

$2$ $pieces$ $of$ $cake$ $=$ $x$

$\frac{2}{2} = 1$

How are piecewise functions and infinite limits alike? How are they different?

Shtirlitz [24]

Answer: i got 100% on the journal activity on EDGE with this “ The difference of piecewise functions and infinite limits is the graphs, with piecewise functions you're graphing several equations... when looking at a graph with an infinite limit there is a difference. A similarity they do have is their end points.” I haven’t been paying attention at all so this I made this up and some how it works(?!)

Step-by-step explanation: I’m not sure if it’s even correct but it worked as a response!

Find a. Round to the nearest tenth.

Kazeer [188]

9514 1404 393

Answer:

21.8 cm

Step-by-step explanation:

A useful way to write the Law of Sines relation when solving for side lengths is ...

a/sin(A) = b/sin(B)

Then the solution for 'a' is found by multiplying by sin(A):

a = sin(A)(b/sin(B)) = b·sin(A)/sin(B)

We need to know the angle A. Its value is ...

A = 180° -75° -31.8° = 73.2°

Then the desired length is ...

a = (22 cm)sin(73.2°)/sin(75°) ≈ (22 cm)(0.9573/0.9659)

a ≈ 21.8 cm

_____

I like to use the longest side and largest angle in the equation when those are available. That is why I chose 75° and 22 cm.

What to did on this .paper thank you for your. please help me

matrenka [14]

So, to solve the questions on your paper, you need to first have all of the bottom numbers on the fractions similar numbers. So if you have the numbers 1/4 and 4/8, you need to get them to both be the same number. Therefore, 1/4 should become 2/8, because you doubled the bottom number (you also then need to do the same to the top number). You don't need to change 4/8, because it's bottom number is already 8. Then, you can take 4/8 and 1/8 and add them. To add them, you just add the top numbers. The top numbers make 5, so then you add the denominator, and make the number 5/8. Since you can't simplify 5/8, just keep it. But if it was 4/8, you could simplify it to 1/2. You can do all of this same to all of the numbers on your paper. :D If you are subtracting, subtract only the top numbers, but if you need to multiply or divide, multiply/divide both numerator AND denominator. :D I hope I helped! If I didn't, please tell me, or just delete my answer. :D
