Answer:

10 doll dresses

Step-by-step explanation:

Number of doll dresses = Length of fabric ÷ length of yard used for one doll

                                       = 4  ÷ (2/5)

                                       = 4 *  \frac{5}{2}\\\\= 2 * 5\\= 10

I Need The Answer Plz!!! Geometry Is Hard!!!
Scorpion4ik [409]

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

\frac{21}{y} =\frac{y}{4}

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10

PLEASE HELP - Part A Find the value of x in the following figure: Part B Find the measure of ACD
Margarita [4]

Answer:

Part A = 90

Part B = 145

Step-by-step explanation:

For part A, we know that a triangle has a sum of 180 degrees. So we just add the angles we already know and then subtract them from 180. For part B, we know that angle ACB and angle ACD are supplementary angles, meaning they add up to 180 degrees. So just take 180 and subtract 35 to find the measure of angle ACD.

If 5 becomes 11 and 12 becomes 25, what does 15 become?
Amiraneli [1.4K]

Answer:

31.

Step-by-step explanation:

5+5 = 10 + 1 = 11

12 + 12 = 24 +1 = 25

15 + 15 = 30 + 1 = 31

I don't know I tried to see if that was the pattern. It checks out math wise.
