Answer:
The correct option is a.
Step-by-step explanation:
Given information:
Number of elements in set A = 4
Number of elements in set B = 3
We need to find n(A × B). It means we have to find the number of elements in set A × B.
If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.



The value of n(A × B) is 12. Therefore the correct option is a.

Step-by-step explanation:
<em>The given information is</em>
- 6 parts of yellow paint with 3 parts of blue paints to make green paint
- The yellow paint adds by 1 part
We need to find the ratio of yellow to blue
<em>Let us find the correct answer</em>
∵ The yellow = 6 parts
∵ The yellow adds by 1 part
∴ The yellow = 6 parts + 1 parts = 7 parts
∵ The blue = 3 parts
∵ The ratio of yellow to blue =
∴ The ratio of yellow to blue = 
The new ratio is
Answer:5 by 8 by 5 by 8
Step-by-step explanation: the perimeter is 26 and one side if 5 so you know that another side is also 5. So add 5 and 5 together you get 10. Then subtract 10 from the perimeter(witch we know is 26) and you end up with 16. we know that the last two side lengths are the same so divide 16 by two and the sidle length is 8.
