The equation for this would be 0.2x=3. Divide each side by 0.2 and you should get 15. That is the original price of the mirror.
we are given the data from 9 to 20. we can plot the data in bar graph. The mean of the data is 15. in this case, we plot the number in x and y in terms of frequency. We can see that the plot is evenly distributed at 15 and then also at the extremes. Hence the answer to this problem is C. symmetric
Answer:
<h2>It's a right triangle. a = 5.</h2>
Step-by-step explanation:
Look at the picture.
We have the triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.
We have:
<em>divide both sides by √3</em>
It's a right triangle.
Answer:
72 pi
Step-by-step explanation:
Think of the lateral surface area as a label on a soup can. When you roll it out, then the circumference becomes the length and the height of the cylinder becomes the width or vise versa. So if 2(pi)(r) is the formula for the circumference, then that is 8. 8*9 is 72 and you multiply that by pi to get 72 pi
