If you are asking how many hot dogs and cans of soda are sold, this is how I solved it.
Given:
cost of hot dog $3
cost of a can of soda $1
total items sold: 350
total sales: $624
let h stand for hot dog and s stand for soda.
h + s = 350
3h + 1s = 624
h = 350 - s
3(350-s) + s = 624
1,050 -3s + s = 624
-2s = 624 - 1050
-2s = -426
-2s/-2 = -426/-2
s = 213 cans of soda
h = 350 - s
h = 350 - 213
h = 137 hot dogs
3h + s = 624
3(137) + 213 = 624
411 + 213 = 624
624 = 624
Mitchell sold 137 hot dogs and 213 cans of soda.
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.

2.5 x 2 is 5, so if he travels at the same rate, you must increase the miles by the same amount. So in this case its 180 x 2, which is 360.
