A) Olaf has 250 files, which represent 100%. 12% of that are photos which number is unknown (x).
250 files - 100%
x photos - 12%
So, the proportion should look like:
250 files : 100% = x : 12%
B) After crossing the products:
x = 250 files * 12% : 100%
x = 30 photos
Hi there!
Step-by-step explanation:
![SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}](https://tex.z-dn.net/?f=SLOPE%3D%5Cfrac%7BY_2-Y_1%7D%7BX_2-X_1%7D%3D%5Cfrac%7BRISE%7D%7BRUN%7D)
![\frac{5-0}{6-1}=\frac{5}{5}=1](https://tex.z-dn.net/?f=%5Cfrac%7B5-0%7D%7B6-1%7D%3D%5Cfrac%7B5%7D%7B5%7D%3D1)
<u><em>Slope is 1.</em></u>
<u><em>Final answer is 1.</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Hope this helps!
Thanks!
Have a nice day! :)

Area of trapezoid = 18 = 1/2 * 6 * h
h = 18 / ( 1/2 * 8) = 6 ft
Area of the square = 6^2 = 36 ft^2
Va = 3.14 x 12^2 x 6/3 = 904.32
Vb = 3.14 x 6^2 x 24/3 = 904.32
so VA = VB
