Answer:
You just find the volume of the cup and subtract the volume of the froth (whatever that is).
V(cup) = pi * r^2 * h
...........= pi * 4.3^2 * 11.2
...........= 650.586cm^3
V(froth) = pi*r^2*h
............= pi*4.3^2*0.4
.............=23.232cm^3
V(hot chocolate) = V(cup) - V(froth)
.........................= 650.586 - 23.232
.........................= 627cm^3
We need to subtract 1050 from 1280, which is 230, now we need to find what percentage 230 is of 1280, so that is 17.97%, so the percentage of decrease I think is 17.97%. Please give 5 stars if right :)
answer: it is correct :The equation is not quadratic in for because it cannot be written as a second degree polynomial
explanation : if the leading term had x^2, then it would be quadratic, but it's not
14lb=224oz
7lb=112oz
12,000lb=6T
22lb=352oz
2T=4,000
16oz=1lb
Hope this helped :)
