Hello!</h2>
The answer is: 2
<h2>
Why?</h2>
Before solving the problem, we must remember the following:
![tan(\alpha)=\frac{sin(\alpha)}{cos(\alpha)}](https://tex.z-dn.net/?f=tan%28%5Calpha%29%3D%5Cfrac%7Bsin%28%5Calpha%29%7D%7Bcos%28%5Calpha%29%7D)
So, for tan(45°) we have:
![tan(45)=\frac{sin(45)}{cos(45)}\\ \\\frac{sin(45)}{cos(45)}=\frac{\frac{\sqrt{2} }{2} }{\frac{\sqrt{2} }{2} }=1](https://tex.z-dn.net/?f=tan%2845%29%3D%5Cfrac%7Bsin%2845%29%7D%7Bcos%2845%29%7D%5C%5C%20%5C%5C%5Cfrac%7Bsin%2845%29%7D%7Bcos%2845%29%7D%3D%5Cfrac%7B%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%20%7D%7B%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%20%7D%3D1)
Also, for sin(30°), we have:
![sin(30)=\frac{1}{2}](https://tex.z-dn.net/?f=sin%2830%29%3D%5Cfrac%7B1%7D%7B2%7D)
Then, substituting and dividing, we have:
![\frac{tan(45)}{sin(30)}=\frac{1}{\frac{1}{2}}\\\\\frac{1}{\frac{1}{2}}=1*\frac{2}{1}=2](https://tex.z-dn.net/?f=%5Cfrac%7Btan%2845%29%7D%7Bsin%2830%29%7D%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D1%2A%5Cfrac%7B2%7D%7B1%7D%3D2)
So, the answer is 2.
Have a nice day!
Answer:
The scale factor is <u>5</u>
Step-by-step explanation:
To find the scale factor, we divide 17 by 3.4 to find how much it was enlarged by.
17/3.4 = 5
We do this becuase when finding the scale factor, we take the dilated shape/side length and divide it by the original shape/side length.
0.13 cents per minute
$50 per month
13 goes into 5,000 = 384
384 minutes per month
I believe it’s 16.6666666 but rounding should be 16.7:)
