Answer: $225
Step-by-step explanation:
Each Notebook costs 45 dollars, this can be found by taking the cost of 2 (90$) and dividing it by 2
Now just take the cost per notebook (45) and multiply it by the amount wanted (5) and your total should come out to $225

Answer:
The sum of a and b is 12.
Step-by-step explanation:
Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect - considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.
Distance between points ( 0, 1 ) and ( 2, 5 )
=
=
=
= =
Distance between points ( 2, 5 ) and ( 7, 0 )
=
=
=
= =
And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly as well. Therefore, you can say that the perimeter of this triangle is = . Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.

Answer:
Step-by-step explanation:
The pigeonhole principal states that if n items are put into m containers, with n > m then at least one container must contain more than one item.
In other words, to find the case where maximum attempts are required, we eliminate all the cases where our criterion is not met and we will be left with the desired result.
For this case, the box has 10 black socks and 12 blue socks.
10 black socks = 5 left foot ones and 5 right foot ones
12 blue socks = 6 left foot ones and 6 right foot ones
If we draw all left foot or right foot ones then we will not have a pair till 11 draws have been made.
The next socks drawn will be a right foot one of blue or black color and a pair will be made.
Therefore, the maximum number of socks needed to be drawn from the box are 12.
