Each sheet of metal cost $20.

Step-by-step explanation:

Given:

Initial amount of sheet with the contractor is, $A_0=12.6\ ft^2$

Amount of sheet used is, $U=2.3\ ft^2$

Cost of remaining sheet, $C=\$206$

Now, let the cost of metal sheet per square foot be 'x'.

Cost of 12.6 square feet sheet = 12.6x

Cost of 2.3 square feet sheet = 2.3x

Therefore, cost of remaining sheet can be obtained by subtracting the used material cost from initial material cost. So,

$12.6x-3.2x=206\\10.3x=206\\x=\frac{206}{10.3}\\x=\$20$

Hence, the cost of metal sheet per square foot is 20 dollars.

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

Answer from: Quest

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data. the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center. with the histogram, we cannot find any of these.
