It takes 18 3/8 inches of wood to make a frame for a small photo. ms. jones has 3 yards of wood. how many frames can she make?

Knowing that 1 yards its 36 inch first we have to multiply 3 times 36 to get much much wood Ms. Jones has.
36*3=108 inches
Finally we have to divide 108 : 18 3/8 to get the answer.
108: 
When we want to subtract number by fraction we can multiply number by inverse of that fraction, so

We have to round down the result, so the answer is 5.

The answer is $9.90 with rounding to the nearest tenth

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
