Answer:

Mrs. Wong spend $545.76 on tiles.

Step-by-step explanation:

Mrs. Wong has 144 tiles that she is going to place on her square kitchen floor. If the tiles are $3.79 each, how much did Mrs. Wong spend on tile?

we are given

number of ties=144

cost of one tie=3.79 dollar

we have to find

total cost of 144 ties

for this we will multiply 144 by 3.79

multiplying 144 by 3.79 gives=144*3.79

it other words

one tile cost=$3.79

and for 144 ties cost

multiplying 144 on both sides

144 tiles cost=3.79*144=$545.76

Using an ordered alphabet of 26 letters, how many ways are there to choose a set of six letters such that no two letters in the

mestny [16]

To find our solution, we can start off by creating a string of 27 boxes, all followed by the letters of the alphabet. Underneath the boxes, we can place 6 pairs of boxes and 15 empty boxes.The stars represent the six letters we pick. The empty boxes to the left of the stars provide the "padding" needed to ensure that no two adjacent letters are chosen. We can create this -
$\binom {21} {6}= \frac{21*20*19*18*17*16}{6*5*4*3*2*1} =21*19*17*8=54264$
Thus, the answer is that there are $\boxed{54264}$ ways to choose a set of six letters such that no two letters in the set are adjacent in the alphabet. Hope this helped and have a phenomenal New Year! 2018
