MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Cookies
Mrs. Smedema likes cookies. Each student in her 8th grade math class presented
her with a cookie. One-third of the students each gave her an oatmeal cookie,
one-sixth of the students each gave her a cinnamon cookie, one-fourth of the
students each gave her a chocolate chip cookie and the remaining 9 students each
gave her a peanut butter cookie. How many students are in Mrs. Smedema’s 8th
grade math class?
--------------------------------------------------------------------------------
There are twice as many girls as boys in Mr. Terpathi’s 7th grade math class.
Each of the girls gave him an oatmeal cookie and each of the boys gave him a
chocolate cookie. Mr. Terpathi arranged the cookies in one row with a chocolate
cookie farthest to the right. Which of the following must be true?
A. The cookie farthest to the left is chocolate.
B. The cookie farthest to the left is oatmeal.
C. There are at least two chocolate cookies next to each other.
D. There are at least two oatmeal cookies next to each other.
E. Mr. Terpathi received more chocolate cookies than oatmeal cookies.
--------------------------------------------------------------------------------
The cookies the students brought to their teachers come in different weights.
Four oatmeal cookies weigh the same as eight cinnamon cookies, two chocolate
cookies weigh the same as three oatmeal cookies, and two peanut butter cookies
weigh the same as one cinnamon cookie. How many cinnamon cookies weigh the same
as one chocolate cookie?
--------------------------------------------------------------------------------
The students in Mrs. Sneed’s 6th grade class each gave her one circular oatmeal
cookie. The cookies were all the same size. They placed the cookies in a
rectangular array so that the number of cookies on the longer side was twice the
number of cookies on the shorter side. The number of students in her class is
greater than 19 but less than 49. How many students are in Mrs. Sneed’s 6th
grade class?
Answer to last week’s MATHCOUNTS problem:
(4000 ÷ 1450) × 9.5 feet = 26.2069 feet. The distance from the floor of the
canyon to the Skywalk is 26.2 feet.
--------------------------------------------------------------------------------
(120 people × 180 pounds/person) ÷ 71,000,000 pounds = .000304
The percent of the capable supporting weight that is on the Skywalk is .03%.
--------------------------------------------------------------------------------
(216 miles ÷ 3 5/6 hours) = 56.35 miles per hour. The average speed is 56 miles
per hour.
-------------------------------------------------------------------------------
($40,000,000 ÷ $15/visitor) = 2,666,666.66...visitors. There will need to be
2,667,000 visitors to pay for the construction costs.
