Answer:
Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

Hello from MrBillDoesMath!
Answer:
The first choice, Pi + (-Pi) = 0
Discussion:
Pi is an irrational number. Saying the irrational numbers <u>are</u> closed under addition means if we add two irrational numbers we will get another irrational number. In our case, Pi + (-Pi) = 0, which is correct, BUT 0 is a <u>rational </u>number. This shows the set of irrational numbers is NOT closed under addition.

it will be 451/100 as an improper fraction! :)
Answer:
Step-by-step explanation:
FYI,
<em>C ∪ D = ( - ∞ , 2 ) ∪ [ 6 , ∞ ) </em>
<em>C ∩ D = ∅ </em>
-46 + (-48) = -94
-42 + 46 = 4
