Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90

Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80

Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70

$273.80 ÷ $3.70 = 74 adult tickets

159 - 74 = 85 child tickets

A chain 27 feet long whose weight is 95 pounds is hanging over the edge of a tall building and does not touch the ground. How mu

bazaltina [42]

Answer:

Work done $= 2,565$ lb-ft

Step-by-step explanation:

The density of the chain in lb/ft is equal to

$\frac{95}{27}$ lb/ft

Total Work done is equal to the summation of work done up to the top of building.

We will use integration for this evaluation.

The mathematical relation is as follows

$\int\limits^{40}_0 {X} \, pdx$

where "p" is the density

Substituting the given values, we get

$\frac{95}{27} \int\limits^{27}_0 {X} \, dx\\\frac{95}{27} X^2\int\limits^{27}_0\\ \frac{95}{27} {27^2 - 0^2}\\\frac{95}{27} * 27 * 27\\95* 27\\= 2,565$

Work done $= 2,565$ lb-ft
