Eight burgers and three orders of fries cost $79.49. Six orders of fries and twelve burgers cost $125.82.Find the price of one b

dezoksy [38]

Answer:

Burgers - $8.29 and fries - $4.39

Step-by-step explanation:

Let burgers - b, fries - f

8b + 3f = 79.49
12b + 6f = 125.82

Double the first equation and subtract the second equation:

16b + 6f - 12b - 6f = 2(79.49) - 125.82
4b = 33.16
b = 33.16/4
b = 8.29

Find f:

8(8.29) + 3f = 79.49
3f = 79.49 - 66.32
3f = 13.17
f = 13.17/3
f = 4.39

Find the volume of a right circular cone that has a height of 4.1 cm and a base with a diameter of 14.8 cm. Round your answer to

podryga [215]

Answer:

$V=235.1\ cm^3$

Step-by-step explanation:

Volume of a Cone

The volume of a right circular cone with height h and a base radius r is:

$\displaystyle V=\frac{1}{3}\pi r^2 h$

The height of the given cone is h=4.1 cm and its diameter is d=14.8 cm. Since the radius is half the diameter, r=7.4 cm.

Calculate the volume:

$\displaystyle V=\frac{1}{3}\pi\cdot 7.4^2\cdot 4.1$

$\displaystyle V=\frac{1}{3}\pi\cdot 54.76\cdot 4.1$

$\displaystyle V=\frac{1}{3}\pi\cdot 224.516$

$\boxed{V=235.1\ cm^3}$
