Since we have a chemist, we can look at the Table of Elements to figure out the two killers :
26 3 58 / 28 27 57 16
FE LI CE / NI CO LA S
Nice, heureka !!!
Thank you, Manuel.....it's been a pleasure to help you.....I wish you the best in the future....

A little tough to read, but I think we have
f(x) = sin ( pi x/ 4)
If so...here's the graph :

39 / 1.25 = 31.2 mpg
2)The radius of a cylinder is 5/6 its height. Find the total surface area of the cylinder if its volume is 150pi.
If the radius is 5/6 the height....then the height is 6/5 the radius
So....we can find the radius thusly :
150 pi = pi (r)^2 (6/5)r
150 = (6/5)r^3 multiply both sides by 5/6
125 = r^3 take the cube root of both sides
5 = r
So...the surface area is given by
2 pi *r * h =
2 pi *(5) * [ (6/5) * 5 ] =
2 pi * (5) (6)
60 pi units^2
1. The height will be the leg of a 6 - 8 -10 right triangle....so...the height = 6
So...the volume is (1/3) pi (8)^2 (6) = 128 pi units^3
C. Circle
The scale factor from the smaller rectangle to the larger is 3
The area of the larger rectangle =
Area of smaller rectangle * (Scale Factor)^2 =
24 * (3)^2 =
24 * 9 =
216 ft^2
The possible sums are
1+ 4 + 0
2+ 2 + 1
3 + 1 + 1
3 + 2 + 0
5 + 0 + 0
So....the possible integers are
104, 113, 131, 122, 140, 203, 212, 221,230, 302, 311, 320, 401, 410, 500
I get 15
