Answer:

(4)

Step-by-step explanation:

L'intersezione si occupa di elementi comuni

segno per intersezione = ∩

A = (1,2,3,4,5)

B = (3,4,5,6,7)

C = (2,4,6,8)

(A∩B)∩C

(A∩B) = (3, 4, 5)

(A∩B)∩C = (4)

a copy shot prints 5,493 pages they use the pages to make 68 same size booklets about how many pages are in each booklet
Aliun [14]

Answer:

80 pages

Step-by-step explanation:

Given:

Number of pages printed = 5493

Number of booklets made = 68

Let each booklet use 'x' pages.

So, pages used by 68 booklets is given by unitary method and is equal to:

=68\times x\\=68x

Now, total number of pages are 5493.

Therefore, the pages used by the 68 booklets should be less than or equal to the total number of pages available. So,

68x=5493\\\textrm{Dividing both sides by 68,we get:}\\x=\frac{5493}{68}=80.8\approx 80(\textrm{As number of pages can't be in decimal})

Therefore, the number of pages in each booklet is 80.

A tennis ball weighs about 57.6 grams. about how many apuntes would 12 tennis balls weigh?
Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

Step-by-step explanation:

The weight of each  tennis ball =  57.6 grams

So, the weight of 12 balls    =    12 x ( weight of 1 ball)

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams
