28 x 6 = 168 hours
168 x 9 = $1512
hope this helps x
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
Multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}
Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.
Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
