Answer:
For a rectangular prism that has a base area B, and a height H, the volume is:
V = B*H
This is the only "tool" that we need to use in this situation.
We know that the wall needs to be 3ft tall, then H = 3ft
And we also know that we have enough bricks for a wall of a volume:
V = 330 ft^3
If we replace these two in the volume equation, we get:
330ft^3 = B*3ft
Now we can solve this for B, and thus find the volume of the base of the wall.
To do it, we just need to divide both sides by 3ft
(330 ft^3)/3ft = B*3ft/3ft
110 ft^2 = B
This means that the area of the base is 110ft^2
As the base is a rectangle of width W and length L, we must have:
110ft^2 = B = L*W
Then the possible measures of the base are given by the linear relation:
L = 110ft^2/W
Where we also need to add some trivial restrictions, like:
L > 0 ft
W > 0ft
This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.

A rake was marked up 25% from an original cost of $8.80. Last Friday, Dean bought the rake and paid an additional 3% in sales tax. What was his total cost?
Answer:
$11.33
Step-by-step explanation:
First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33
The total cost of the rake is $11.33.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, a rake was marked up 25% from an original cost of $8.80.
25% of the original cost of $8.80 is
0.25×8.80 =$2.2
So the marked up price was 8.80+2.20
= $11
He then paid an additional 3% in sales tax, that is
11 + 0.03×11 = $11.33
Therefore, the total cost of the rake is $11.33.

Find the value of y. Round to the nearest tenths place.
Answer:
y = 12
Step-by-step explanation:
Look at the left triangle first. Opposite the 30 degree angle (not shown) is the shortest side, which (according to the sine function) is half the hypotenuse, or 2√3. Then (2√3)² + x² = (4√3)², or
4(3) + x² = 16(3). Thus, x² = 16(3) - 4(3) = 12(3) = 36, and so x = 6. Again using the sine function, we find that x = 2y = 6, so, using the sine function, we find that sin 30° = 6/y. Thus y = 6 / (2/1) = 12 = y

In a game involving a standard deck of 52 playing cards, an individual randomly draws 7 cards without replacement. Let y = the number of kings drawn. Is y a binomial variable? Why or why now?
Answer:
Step-by-step explanation:
By definition, we will see that y is a binomial variable.
Here the variable "y" represents:
y = "number of kings drawn"
When we draw 7 cards out of a 52 cards deck.
So there are 5 possible values of y:
y = 0y = 1y = 2y = 3y = 4A binomial variable is a variable that represents two outcomes, for example, if we used the variable x = "drawing a king" 7 times, then x is a binomial variable, because it has two outcomes, or you draw a king, or you don't.
A binomial variable can also represent the number of outcomes of each type for several events like x (the one defined above). This is what y does, it counts how many times the outcome of "x" is "drawing a king" for a sequence of 7 draws.
Then y is a binomial variable.

If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\
Answer:
Solve for X; whereas lb=pound, $=cost
1lb = $12.55
0.6lb = $X; therefore 6/10 lb = $X
Rewrite:
$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10
X=$7.53 for .6 lbs.

Step-by-step explanation:
The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units
What is the distance of a line between 2 points?
The distance of a line between 2 points is always positive and given by the formula
Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )
The distance between A and B is D , and the distance D is
[tex]Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
Given data ,
Let the distance between the two points be = D
Let the first point be represented as = A
The value of A = A ( 2 , -12 )
The second point be represented as = B
The value of B = B ( -11 , -12 )
Now , the distance between the points A and B is given by the equation of distance formula
[tex]Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
Substituting the values in the equation , we get
[tex]Distance D = \sqrt{(-12-(-12)^{2} + (2-(-11))^{2} }[/tex]
On simplifying the equation , we get
[tex]Distance D = \sqrt{(0 + (2+11))^{2} }[/tex]
[tex]Distance D = \sqrt{(13)^{2} }[/tex]
[tex]Distance D = 13[/tex]
Therefore , the value of D is 13
Hence ,
The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units

In a kindergarden class of 19 students, 100 addition problems can be completed in a mean time of 6 minutes. The
standard deviation is 1 minute.
How many students will finish before 5 minutes?
Answer:
3 students
Step-by-step explanation:
Two ways you can do this:
1. If you have a graphic calculator you can find the normal distribution function and enter the following values to get the probability of a student finished in less than 5 minutes:
Lower: 0
Upper: 5
Standard Deviation: 1
Mean: 6
This gives a probability of: 0.1587 (4.d.p)
2. You can use the formula and find the probability using the Z-table.
[tex]Z = \frac{x - \mu}{\sigma}[/tex]
Substitute known values:
[tex]Z = \frac{5 - 6}{1}\\Z = -1/1 = -1\\[/tex]
It is one standard deviation to the left of the mean,.
Look up on Z-score table and we get: 0.1587 (4.d.p)
Now we need to find expected number. We do this by multiplying the probability by the amount of people:
0.1587 x x19 = 3.0153 rounded to 3 students.
