Answer:
The least possible number of people in the family is 8.
Step-by-step explanation:
To determine the minimum number of people that make up the family, knowing that 0.83 of the children are boys, the following logical reasoning must be carried out:
Given that 0.83 is the result of 5/6, it can be said that 5 of the 6 children of the couple are boys. These 6 children must be added to the 2 fathers of the family, with which the total number of family members is 8.
To solve this problem you will need to use the cross product method:
1/16 of an hour → write 1 card
3/4 of an hour → write X cards
(3/4) ÷ (1/16) = X
0.75 ÷ 0.0625 = X
12 = X
Joey can write 12 Thank you cards in 3/4 of an hour.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
(2x+1) (x+4)
Explanation:
The idea is to break down the middle term into two monomials which can be used in the factorization process. Note that
2.4=8=8.1
, and that we may write 9=8+1
, which may help us in the process.
Let us write:
2x^2+9x+4
=2x^2+8x+x+4
=2x(x+4)+(+4)
=(2x+1)(x+4)
