3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
500 adult tickets and 350 children tickets.
Check :
500A($1.5)=$750
350C($1)=$350
$750 + $350 = $1100 AND 500 + 350 = 850 tickets
R= 18
d=r(2)
36=r(2)
36/2=r(2)/2
18=r
y=3 when x=15
this is because we can set up a ratio of when x/15 and set it equal to 6/30 and divide them, solve for x.
You will need to use the Pythagorean Theorem and plug in the varibles. The rope is the hypotenuse of the right triangle formed, and the 40ft water is the vertical leg, which leaves the ocean floor to be the horizontal leg.[a^{2}+b^{2}=c^{2}\] \[a^{2}+40^{2}=140^{2}\] Then solve for a. \[a^{2}=18000\] \[a=134.164\]
