X) 5.3.PS-10 Question Help
Swimming Pool On a certain hot summer's day, 290 people used the public swimming pool. The
daily prices are $1.75 for children and $2.00 for adults. The receipts for admission totaled $568.50.
How many children and how many adults swam at the public pool that day?

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

10+4√2 is the answer. i dont have the time to explain.

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
