Find Angle B:  B = 180 - (82+55) = 43.  Then apply the law of sines:

   b            8 cm
--------- = ----------
sin 43       sin 55
                                        (sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).

Answer:

The sharing cone holds about 9 times more popcorn than the skinny cone.

Step-by-step explanation:

Cone volume:

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

r is the radius and h is the inches.

Skinny-size cone:

Radius is r, height h. So

V_{sk} = \frac{\pi r^{2}h}{3}

Sharing size:

Radius is now 3r. So

V_{sh} = \frac{\pi (3r)^{2}h}{3} = \frac{9\pi r^{2}h}{3} = 3\pi r^{2}h

How many times more popcorn?

r = \frac{V_{sh}}{V_{sk}} = \frac{3\pi r^{2}h}{\frac{\pi r^{2}h}{3}} = \frac{3*3\pi r^{2}h}{\pi r^{2}h} = 9

The sharing cone holds about 9 times more popcorn than the skinny cone.

Help me with number 8
kirza4 [7]
Supreme sold 29 tires.  Set it up like this, with Supreme as your x and Prestige as y: 48x + 56y = 2008.  This is an equation in terms of money, with x being the number of Supreme tires sold at $48 each and y being the number of Prestige tires sold at $56 each. We know that Prestige sold 11, so sub it for y and do the math: 48x = 2008 - 616; x = 29
