4. Brother's Burgers claim to make the best 2 pound burgers in all of Florida. a. The hamburger patties are 12 pound before they put them on the grill.
When they come off the grill, they are 1/3 pound. What is the change of
percent in weight?
b. I like a lot of toppings on my Brother's Burger, and after I get done, the
total weight of my hamburger, bun, and toppings is 5/8 pound. What is the
percent change from cooked weight to final weight?
C. What is the percent change from pre-cooked weight to final weight?

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
