For A = {a,b}, determine A x P(A).
alex41 [277]

Answer:

Since A={a,b}, then P(A)=\{\emptyset, \{a,b\}, \{a\}, \{b\}\}. Remember that the Cartesian Product of two sets A, B is defined by

A\times B=\{(x,y): x\in A \text{ and } y\in B\}. Then

A\times P(A)=\{(a,\emptyset),(a,\{a,b\}),(a,\{a\}), (a,\{b\}), (b,\emptyset),(b,\{a,b\}),(b,\{a\}), (b,\{b\})\}

A book is marked down by 28 percent from an original price of $19.50. What is the new price?
kotykmax [81]
First find 28% of $19.50:

($19.50) / (100) x (28) = $5.46

Now minus the 285 from the original price:

($19.50) - ($5.46) = $14.04

The answer is $14.04
Hope it helped :)

Which decimal is greater: 0.347 or 0.437?
trapecia [35]

Answer:

0.437

Step-by-step explanation:

Decimals are read the same as whole numbers, starting with the first digit, which is the largest, to the right. So, to find the larger decimal you need to look at the first digit. If this digit is the same then continue to the right until there is a difference in the number. In this case, the first digit is different. Therefore, whichever has the larger first digit must be the greater one. Since 4 > 3, 0.437 must be greater than 0.347.
