Distance Formula - answer
A naval detachment has enough rations to feed 16 people for 10 days. If 4 more people
join the detachment, how many fewer days will the rations last? - answerAmount x Time
= Amount x Time
16 * 10 = 20x
160/20 = 20/20x
x=8
10-8 = 2 fewer days
Simplify N+6N²/6N+1 - answerPlug in #1
1+6(1)²/6(1)+1

7/7 = 1
Multiply Large Whole #'s 800 × 300 - answer800 × 300 there are 4 0's
, 8×3=24 plus 4 0's
=240,000

Assume that it takes an average of 3 man-hours to stack 1 ton of a particular item. In
order to stack 36 tons of that item in 6 hours, the number of persons required is? -
answer1. Time × Amount
3×36=108 total hours
2. Hours/Time
108/6=18
It will take a total of 18 men
Successive discounts of 20% and 15% are equivalent to a single discount of? -
answer100×20%=20
100-20=80
80×15%=12
80-12=68
100-68=32
A number X was increase by 4% the result being 17.16. What is X? - answerWe have to
find a 100% of that #
104%
17.16/107=16.50
Square root of √729 - answerFinding the square root of a # is two of the same #
multiplied
√729= 27×27 = 729
Thus,
√729 = 27
Simplifying a Radical
√48 and √72,900 - answer√48 = √16.3 = √16√3 = 4√3
√72,900 = √729*100 = √9*81*100 = 3 x 9 x 10 = 270
