yuradex [85]
The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.
To find the radius, we would find the square root of 144, which is 12.
r=12

The ratio of doves to parrots in a cage is 1 to 2. If there are 6 doves and parrots altogether then how many parrots are there?
Mama L [17]
There would be 2 doves and 4 parrots.

2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.

Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. {1, 2, 3, 5, 7, 8, 11, 14} {5}
Maslowich

The intersection of given set a and b is a∩b = {5}.

According to the given question.

We have two sets a and b.

a = {2, 5, 8, 11, 14}

And, b = {1, 3, 5, 7}

As, we know that "the intersection of two sets A and B is the set of all those elements which are common to both A and B. Symbolically, we can represent the intersection of A and B as A ∩ B".

Since, only the element which is common to set a and set b is 5.

Thereofore, the intersection of given set a and b is given by

a∩b = {5}
