How many ounces in a pound - answer16
How many pints in a gallon - answer8
How many quarts in a gallon - answer4
How many pounds in a ton - answer2,000
Formula to find degrees in shapes - answer(# of sides -2)*180= total number of degrees
Supplemental angle - answer adds up to 180
Complementary angle - answer adds up to 90
2r-.5t=5 means ... - answer if 2 times r exceeds one-half of t by 5
3x-1/3*y=9 means... - answer if 3 times x exceeds 1/3 of y by 9
questions about how fast people can do a job together - answertime actually
needed/time needed to do job alone=1
ex. one recruiter can complete an assignment in 40 minutes; another can complete it in
one hour. how long to complete the assignment if they work together? x/40 + x/60=1
x=24 minutes
question with an acid solution. take te pure acid volume of x - answerP1*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
ex. how much pure acid must be added to 12 ounces of a 40% acid solution in order to
produce a 60% acid solution? 100x+480=60(12+x), x=6
A can complete a project in 20 days and B can complete the same project in 30 days. If
A and B start working on the project together and A quits 10 days before the project is
completed, in how many days will the project be completed? - answerA will complete
1/20 of project in 1 day and B will complete 1/30 of project in 1 day. total number of
days to complete project is x. B worked for all x days, but A worked for x-10 days. x-
10/20 + x-30=1solving for x gives 18 days
