At a certain ice cream parlor,customers can choose among five different ice cream flavors and can choose either a sugar cone or a waffle cone.Considering both ice cream flavor and cone type,how many distinct triple-scoop cones with three different ice cream flavors are available?
Question 10
A firm selling Manchester United pillowcases for $10 currently generates an annual turnover of $ 500,000.Variable costs average at $4 per unit and total annual fixed costs are &100,000.The marketing director is considering a price increase of 10%.Given that the price elasticity of the product is believed to be 0.4,please calculate:(Price elasticity = % change in quantity demanded / % change in price)
A.\x05The old sales volume (EXPRESS IN UNIT TERMS)
B.\x05The new sales volume (EXPRESS In UNIT TERMS)
C.\x05The new revenue (EXPRESS IN $ TERMS)
D.\x05The expected change in profit following the price increase (EXPRESS In % TERMS)

1.500000/10=50000
2.P=-0.4*10%=-4%,销量n=50000*（1-4%）=48000
3.M=48000*（1+10%）*10=528000
4.旧利润=500000-4*50000-100000=200000
新利润=528000-（48000*4+100000）=236000,利润增长率=36000/200000=18%

这是英语题吧……

1.x^2+kx-2的一个根是1，则它的另一个根是多少？ x^2+kx-2=0的话，把x=1代入，求出k=1,所以：x^2+x-2=0求出另一个根：x=-2 2.kx

fullfill the answer of question 9:
We can choose the 3 distinct flavors out of the available 5 in C(5,3) = 5! / ( 3! (5-3)! ) = 10 ways.
For each such choice, we can choose one of the two available cones in C(2,1) = 2 ways.
So the number of possible flavor-triplet-cone combinations is C(5,3)*C(2,1)= 20.
