NAVY OAR MATH Skills
16 ounces - answer1 pound
8 pints - answer1 gallon
4 quarts - answer1 gallon
2000 lbs (pounds) - answer1 ton
total # of degrees - answer(# of sides - 2) x 180
supplmentary angles - answer2 angles whose sum is 180 degrees
complementary angles - answerTwo angles whose sum is 90 degrees
If 2 times r exceeds one-half of t by 5, which of the following represents the relationship
between r and t - answer2r - .5t = 5
If 3 times x exceeds 1/3 of y by 9, which of the following is the equation that shows the
relationship between x and y? - answer3x - 1/3 * y = 9
questions about how fast people can do a job together - answerTime actually
needed/time needed to do the job alone = 1
One recruiter can complete a certain assignment in 40 minutes; another can complete
the same assignment in one hour. How long would it take to complete the assignment if
they worked together? - answerx/40 + x/60 = 1
so, x = 24 min
Question with an acid solution - answerTake the pure acid volume as X.
P1*V1 + P2*V2 = P3*V3
P1*V1 would be X*1
P2*V2 is volume of first*percentage of first
P3*V3 =(X+volume of first solution)*volume of final
solve for X
Example: How much pure acid must be added to 12 ounces of a 40% acid solution in
order to produce a 60% acid solution? - answer100x + 480 = 60(12+x), x=6
Questions about discount price - answeramount of discount/original price = % of
reduction
