Answer the following questions concerning the poset ({3, 5, 9, 15, 24, 45}, | ) (the divisibility relation on the set) Find the maximal elements 3 5 9 15 24 45 Find the minimal elements 3 5 9 15 24 45 Find the minimum, if it exists 3 5 9 15 24 45 none Find the maximum, if it exists 3 5 9 15 24 45 none Find all upper bounds of {3,5} 3 5 9 15 24 45 none Find the least upper bound of {3,5} if it exists 3 5 9 15 24 45 none Find all lower bounds of {15,45} 3 5 9 15 24 45 none Find the greatest lower bound of {15,45} if it exists.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
