Math Challenge

November 30, 2005, 06:49:00 pm »
Lets see how intelligent the people who play on Layo are (no offense intended, just a joke!)
Heres some good math.
This is kind of a test im putting on, post the number and the answer next to it. PM me if you want to know your score. I will then PM you the number of questions correct. (if it really bugs you i will tell you which ones you got wrong, but would prefer not to so everyone has the same chance)
It starts easy and gets more difficult as questions increase
Oh and please dont use a calculator, this is a paper and mind test.
1) Evaluate
43921
- 8754
------
2) What is two-thirds of sixty percent of half of seventy-five?
3) What values of z satisfy 2(3-4z)-3(3z-2) = 80?
4) When the digits of a two digit positive number are reversed, the resulting positive two digit number is 72 less than the origional number? What is the number?
5) What is the name foir a line segment in a triangle with endpoints on a vertex and the side opposite the vertex?
6) A well is dug in the shape of a right circular cylinder with radius of one meter and depth of fifty meters. What is the volume of cubic meters, of dirt in the well?
7) What is the sum of the squares of the roots of the equation p^3+2p^2+3p+4=0?
("^" means "to the power of")
8)Express the product of 345 base 8 and 67 base 8 in as a base 8 numeral.
9) What is the sum of the elements of
[-2 5]^-1
[ 3 -7]
(with "^-1" i mean the inverse of the matrix. hint, hint)
10) A class of 13 students orders ice cream. The oprder is read over the phone to the ice cream store and clerk fills the order and delivers the ice cream to the class. The names of the studetns are not included in the order, just the number of cones of different flavors. There is only one flavor per cone for each student. The possible flavors are vanilla, chocolate, walnut, strawberry, and peach. How many different ice cream orders would be possible for this class?
That's it hope you enjoy it. Ill post a more challenging one if people actually participate in this one.
Hope you have fun, happy thinking!

As a Math teacher and UIL (UIL -> ruler of all competitive things in Texas schools) Mathematics/Number Sense/Calculater sponsor, I refuse to answer anyone of those questions, lest I reduce myself to spending my freetime on my vocation.

Four out of ten on something that is done for fun is half-decent. Although, I did notice that it is mostly algebra. One of the questions is geometric, another is a proportion.

I would do these problems,but I don't think I would at all. I have math class at school... and then for some reason I agreed to do Math League. So.... sorry, but I do enough math as it is.

Math can be entertaining as long as it is not found to be too easy, too hard, or presented dully. (for me anyway.)
