Find the volume of a pyramid with a square base, where the perimeter of the base is 7.3\text{ ft}7.3 ft and the height of the pyramid is 6\text{ ft}6 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
[tex]V=6.66\ ft^3[/tex]
Step-by-step explanation:
The perimeter of the square base of a pyramid = 7.3 ft
The height of the pyramid, h = 6ft
The perimeter of a square is given by :
P = 4s, s is the side of square
7.3 = 4s
s = 1.825 ft
The volume of a pyramid is given by :
[tex]V=\dfrac{lbh}{3}[/tex]
Here, l = b = 1.825 ft
So,
[tex]V=\dfrac{1.825\times 1.825\times 6}{3}\\\\V=6.66\ ft^3[/tex]
So, the volume of the pyramid is equal to [tex]6.66\ ft^3[/tex].

IF the equation y = 2x + 1 were graphed on the given xy plane, where would the two lines intersect?
7.(08.03)
Consider the following pair of equations:
y = x + 4
y = - 2x - 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (20 points!)
Answer:
(-2, 2).
Step-by-step explanation:
y = x + 4
y = - 2x - 2
Substitute y = x + 4 in the second equation:
x + 4 = -2x - 2
x + 2x = -2 - 4
3x = -6
x = -2.
Now substitute x = -2 in the first equation:
y = -2 + 4 = 2.
Check the results by substituting for x and y in equation 2:
2 = -2*-2 - 2 = 4 - 2 = 2. - this checks out.
Answer:
(-2, 2).

The width of a triangle of 7 feet longer than its length. Find the dimensions of the rectangle such that the perimeter of the rectangle is 162 feet
Answer:
Length = 37 feets
Width = 44 feets
Step-by-step explanation:
Given that :
Length = l
Width, w = 7 + l
Perimeter , P of rectangle = 162
Recall:
Perimeter of a rectangle = 2(l + w)
P = 2(l + w)
162 = 2(l + (7 + l))
162 = 2(l + 7 + l)
162 = 2(7 + 2l)
162 = 14 + 4l
162 - 14 = 4l
148 = 4l
l = 148 / 4
l = 37 feets
Width = l + 7
Hence,
Width = 37 + 7 = 44 feets

If a line plot were to be made, the number of "X"s placed above the 2 would be ____
above the 3 would be
____
above the 4 would be _____
and above the 5 would be
_____.
Answer:
No. X's above 2: 1
Above 3: 1
Above 4: 3
Above 5: 3
Step-by-step explanation:
Drawing a line plot of a data set means that you record the number of times that particular value shows up in the set. 2 on the line plot would only have 1 'X' placed above it because there is only one 2 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
3 would also have 1 'X' above it because there is also only one 3 in the data set:
5, 5, 4, 3, 2, 5, 4, 4
Similarly, 4 and 5 would both have three 'X's because there are three 4's and three 5's in the data set:
4's: 5, 5, 4, 3, 2, 5, 4, 4
5's: 5, 5, 4, 3, 2, 5, 4, 4

(b) Principal = * 8000, Rate = 8% p.a., Time=2*1/2years
Answer:
Step-by-step explanation:
time=1 years
interest=principal*time*rate/100
=8000*1*8/100
=64000/100
=640
therefore interest=640
Answer:
Compound Interest = 9680
Step-by-step explanation:
The formula of Compound Interest: [tex]A = P(1 + \frac{r}{n} )^n^t[/tex]
Where;
A = Compound Interest
P = Principal amount
r = Rate of interest
n = amount of deposite annually
t = total time
Therefore:
[tex]A = 8000(1 + \frac{0.08}{1})^1^*^2^.^5[/tex]
[tex]A = 8000(1 + 0.08)^2^.^5[/tex]
[tex]A = 8000(1.08)^2^.^5[/tex]
A = 8000(1.21)
A = 9680
Therefore, the compound interest = 9680

Step-by-step explanation:
which of the following cannot be the graph of a function of X?
Why not? Because it fails the vertical line test. Here it is possible to draw a single straight vertical line through more than one point on the curve. That's why choice D is not a function. Choices A,B,C are functions because it's impossible to draw a single vertical line through more than two points on the curve, and therefore we can say they pass the vertical line test.
Side note: choices B and C fail the horizontal line test, so these functions are not one-to-one.

There are 8 sweets in a box. There are n jelly beans and the rest are cola bottles. Colin takes 2 sweets out of the box at random. Write an expression for the probability of getting 2 cola bottles. Give your expression as a single fraction and simplify fully.
Answer:
Probability expression = 1 - n/7 - n/8 + n^2 / 56
Probability single fraction based on example = 3/28
Step-by-step explanation:
Total sweets = 8. n jelly beans , 8 - n cola bottles
Prob (getting 1st cola bottle) = Cola bottles / Total sweets = (8-n) /8
Prob (getting 2nd cola bottle) = remaining cola bottles / remaining total sweets = (8 - n - 1) / (8-1) = (7-n) / (7)
Prob (getting both 1st & 2nd cola bottle) = [ (8-n) /8 ] x [ (7-n) / 7 ]
(1 - n/8) x (1-n/7) = 1 - n/7 - n/8 + n^2 / 56
Eg : 5 jelly beans , 3 cola bottles
Similarly, Prob (2 cola bottles) = 3/8 x 2/7 = 6 / 56 = 3/28
