2/5 = (2x2)/(5x2) = 4/10 = 0.4
Percent means per 100
think cent as in 100 pennies in a dollar
To convert from percent to decimal, we divide by 100 or move the decimal over 2 spots, so,
15% = 15/100 = 0.15
Now multiply 0.15 by 850 to find the discount saved
0.15*850 = 127.50
So you'll save $127.50
The final price is therefore: 850-127.50 = 722.50
A shortcut is to multiply 850 by 0.85
850*0.85 = 722.50
We get the same answer
The 0.85 comes from the fact that if you get 15% off, then you pay 85% of the original price
Answer: $722.50

So, r' (the new r) becomes kr, and h'=h*k,
so V' = pi * (r')^2*h' = pi * (r*k)^2*(h*k) = pi*r^2*h*k^3 = V * k^3

Reflection is the way of projecting a mirror figure to the other side of the axis of symmetry. When reflection is done, like what we can observe in the mirrors, the properties that can be observed are parallelism, colinearity and angle measure. Orientation is not preserved. Answer is C
