Please i don't understand set theory in mathematics
nordsb [41]

Set theory is the mathematical theory of well-determined collections, called sets, of objects that are called members, or elements, of the set. ... The axioms of set theory imply the existence of a set-theoretic universe so rich that all mathematical objects can be construed as sets

For example, if A = {1, 2, 3} and B = {1, 2, 3, 4, 5} then A Í B (Í means is a subset of). If A = {1, 2, 4, 8}, then n(A) = 4. This is because n(A) means the number of members in set A. The universal set is the set of all sets.

If the can of dogfood holds 8 ounces and the bag of dogfood holds 30 times the volume , how many pounds of dogfood does the bag
Maru [420]

Answer:

15 pound in a bag

Step-by-step explanation:

one can= 8 oz

one bag= 30 times the amount in a can

               8 oz x 30 =  240 oz in a bag

Question asked how many pound is in one bag of dog food:

We know that 16 oz = 1 pound

                       240 oz = x pound

To find x pound we divide 240 oz by 16 oz-->

240 oz/ 16 oz = 15 pound

How do you find the equality of 4/12=A/3
Rama09 [41]

Answer:

A = 1

Step-by-step explanation:

frac. \: \frac{4}{12}  =  \frac{a}{3}

\frac{  \:  \: \: 4  \: \div  \: x  \: =  \: a}{12  \: \div \:  x \:  = \:  3}

\frac{  \: \: 4  \: \div \:  x  \: =  \: a}{12 \:  \div \:  4  \: =  \: 3}

\frac{ \:  \: 4  \: \div \:  4  \: = \:  a}{12  \: \div  \: 4 \:  =  \: 3}

\frac{ \:  \: 4  \: \div \:  4  \: =  \: 1}{12  \: \div \:  4 \:  =  \: 3}

a= 1

The area of a baseball field bounded by home plate, first base, second base, and third base is a square. If a player at first ba
JulsSmile [24]

Answer:

ta side from one base to next has  length of x. so we know each side has length x and  the shape they make is a square. This means we are only searching for the diagonal of a square. remember that a diagonal forms and isoscoles right triangle with the 2 sides being equal and the diagonal as the hypotenuse. Using  pythagoream theorem we can say

a^2 + b^2 = c^2 all side lengths are x so we can put x in for a and b  to get

x^2 + x^2 = c^2

2x^2 = c^2

c = x * squareroot(2)

so if the length between bases is 90 ft

c = 90 ft * squareroot(2)

c = 127.28 ft
