Answer:
- {thermometer, fridge, rusty nail, deoderant}
- {credit card, face wash, tweezers, shovel}
- {clothes, glass, car, greeting card}
Step-by-step explanation:
The options that will be equivalent to T will have to be the options that have the same Cardinality as T. Cardinality refers to the number of elements in a set and in the set T, there are 4 elements being Tinkey-Winky, Laa-Laa, Dipsy, Po so the Cardinality is 4.
The equivalent sets would therefore be sets with a cardinality of 4 as well and those are;
- {thermometer, fridge, rusty nail, deoderant}
- {credit card, face wash, tweezers, shovel}
- {clothes, glass, car, greeting card}
Answer: is that all the information in the problem??
What I did was add all the x's since you are trying to find the perimeter then I got 16 and then you add the whole numbers. 16x+3
The number of books sold is 473.
<u>Step-by-step explanation:</u>
- The original cost of each book = $0.64
- The selling price of each book = $0.75
The difference between the original price and selling price of the book gives the profit per book.
The profit of one book = Selling price - Original price
Let,
- The total number of books be 'x'.
- The number of books sold be 'y'.
- The unsold books is 100.
- The total profit is -12 because it was gone to a loss of $12.
Therefore, the equation is formed as
total Profit = 0.75y - 0.64x
⇒ 0.75y - 0.64x = -12 --------(1)
Total books = sold books + unsold books
x = y + 100
⇒ x-y = 100 -------(2)
Substitute x= 100+y in the eq(1),
0.75y - 0.64(100+y) = -12
0.75y - 64 -0.64y = -12
0.11y = -12 +64
y = 52 / 0.11
y = 472.7
y ≅ 473
The number of book sold is 473 books.
The total number of books is (100+473) = 573 books.
