Triangle, Circle and Parabola
What are the properties of conic sections?Looking at the given options, we can say that ellipse, circle and parabola are all conic sections and as such they are possible figures that can be made if we intersect a plane and a cone.
However, rectangle is not a conic section.
A cylinder which could have a rectangular cross section if the plane is perpendicular to the base or A tetrahedron could have a square cross section, which is a special case of a rectangle.
In forming a conic section , we could also form an ellipse.
Now, when we cut a cross section across a cone, we can get a circle, triangle or parabola

Randy is designing a circular garden that is 18 feet in diameter. He is buying plastic edging that costs $1. 50 per foot. He can only buy edging in whole-foot amounts. How much does it cost Randy to buy edging for his garden? Use 3. 14 for pie.
If the diameter of circular-garden is 18 feet, then it will cost Randy an amount of $85.50 to buy edges for his garden.
The "Circumference" of circle is defined as the "total-length" of the boundary or the outer edge of the circle.
The circumference formula is : Circumference = π × Diameter,
The "diameter" of garden is = 18-feet,
So, Circumference = 3.14 × 18 = 56.52 feet,
Since, Randy needs to buy plastic-edging to cover the entire circumference of garden, he needs to buy 56.52 feet of edging.
We know that, Randy can only buy edging in whole-foot amounts,
So, rounding up to the nearest whole foot, we get 57 feet,
The cost of edging is = $1.50 per foot,
So, "total-cost" for Randy to buy edging for his garden is,
⇒ Total Cost = (Cost per foot) × (Number of feet),
⇒ $1.50 × 57,
⇒ $85.50
Therefore, it will cost Randy $85.50 to buy edging for his circular garden.

Find the equation of the line that is perpendicular to the line AB and passes through the point. (0,2)
The equation of a line perpendicular to line AB and passing through point (0,2) is y = -4x + 2.
The given line has a slope of 1/4, so the slope of any line perpendicular to it will be -4 (the negative reciprocal).
Using the point-slope form of a line, we can write the equation of the line passing through the point (0,2) with slope -4 as
y - 2 = -4(x - 0)
Simplifying, we get
y - 2 = -4x
Adding 2 to both sides, we get
y = -4x + 2
Therefore, the equation of the line passing through the point (0,2) which is perpendicular to the line y=1/4x+5 is y = -4x + 2.

The histogram below shows the results of a survey on the number of traffic tickets received by a random group of drivers. 3 86 76 51 Number of People A 1 9 2 Traffic Tickets 10 8 6 Number of Traffic Tickets Step 6: How many people received either 4 or 5 traffic tickets? 12
In reference to the given histogram, an absence of bars signifying either 4 or 5 traffic tickets implies that no one from the selection had accumulated this amount.
How to explain the histogramIt should be noted that to make sure our point is accurate, we can sum the heights of the separate bars for 3, 6 and 8 tickets which demonstrate the total people included within the survey who have acquired the relevant number of traffic citations.
The height of the bar for three violations measures out at 1.
Conversely, a measurement of 2 denotes the bar for six infringements.
An assessment of 1 has been given to the bar with regards to eight offences.
Due to the lack of representation mentioned in the histogram concerning both 4 and 5 transgressions, it confirms our inference: nobody from the selection received four or five traffic tickets.

The expression 7∛7 - ∛128 is: 49∛7 - 8∛2.
What is the expression?We can simplify this expression using the fact that ∛(a * b) = ∛a * ∛b and ∛(a^3) = a.
First, let's factor ∛128 into prime factors: ∛128 = ∛(2^7) = 2 * ∛(2^5) = 2 * ∛(32).
Next, we can simplify 7∛7 as much as possible:
7∛7 = ∛(7^3) * ∛7 = 7∛(7^2) * ∛7 = 7 * 7∛7.
Now we can substitute these simplifications into the original expression:
7∛7 - ∛128 = 7 * 7∛7 - 2 * ∛32
We can simplify ∛32 as follows:
∛32 = ∛(2^5) = 2 * ∛(2^2) = 4∛2
Now, we can substitute this back into the expression:
7 * 7∛7 - 2 * ∛32 = 7 * 7∛7 - 2 * 4∛2
= 49∛7 - 8∛2
So the simplified expression is 49∛7 - 8∛2.

Thus, the value of the x- and y-intercepts for the given linear equation is (-30, 0) and (0, 15)
Explain about the x- and y-intercepts:A nonlinear function's intercepts can be defined algebraically or graphically. The points on a graph where a nonlinear function crosses both x and y axes are known as the intercepts.
The terms "y-intercept" and "x-intercept" both refer to the values at the places where the graph crosses the y-axis and the x-axis, respectively.Keep in mind that x is zero at the y-intercept and y is zero at the x-intercept. According to algebra, a function's y-intercept is its value when x equals zero, and its x-intercept is its value when y equals zero.Given that-
linear equation: -x + 2y = 30
x-intercept: It occurs when y = 0,
-x + 2(0) = 30
-x = 30
x = -30
y-intercept: It occurs when x = 0,

Question 12
A recent conference had 750 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?
There were about 193 principals in attendance.
There were about 260 principals in attendance.
There were about 557 principals in attendance.
There were about 680 principals in attendance.
The activity with a central angle of 54° is Kayaking and there were about 557 principals in attendance based on the prediction
The activity with a central angle of 54°The formula to calculate the central angle for an activity is:
central angle = (number of campers for the activity / total number of campers) x 360°
Using this formula, we can calculate the central angle for each activity:
Kayaking: (15/100) x 360° = 54°
Wakeboarding: (11/100) x 360° = 39.6°
Windsurfing: (7/100) x 360° = 25.2°
Waterskiing: (13/100) x 360° = 46.8°
Paddleboarding: (54/100) x 360° = 194.4°
Therefore, the activity with a central angle of 54° is Kayaking.
Predicting the number of principals in attendance at the conference?To make a prediction about the number of principals in attendance at the conference, we can assume that the proportion of principals in the exhibit room is similar to the proportion of principals in the whole conference.
In the exhibit room, out of 70 people, 52 were principals.
So, the proportion of principals in the exhibit room was 52/70
We can predict the number of principals in attendance at the conference as follows:
Number of principals = proportion of principals x total number of attendees
If we plug in the values, we get:
number of principals = 52/70 x 750 = 557
So, based on this prediction, we can say that there were 557 principals in attendance at the conference.

c. Probability that the second set is green is = 0.06
d. The probability that both the sets are green is = 0.48
e. The probability that at least one set is green is = 0.86
Define probability?The likelihood that an event will occur is described by probability. There are many circumstances in real life where we may need to foresee how something will turn out. We might be able to predict the outcome of an event or we might not. At this point, we say, "There is a chance that the event will happen or not."
Here in the question,
b.
The probability that the first set is green is:
P = 1 - 0.2
= 0.8
c.
Now the first set is given as not green.
Probability that the second set is green is:
p = 0.2 × 0.3
= 0.06
d.
Now probability that both the sets are green is:
P = 0.8 × 0.6
= 0.48
e.
When both the sets are not green, probability is:
0.2 × 0.7
= 0.14
So, probability that at least one set is green is:
P = 1- 0.14

E 300
If 15% of "x" is 20% of "y", then "y" is 75 percent of "x", the correct option is (c).
The "Percentage" is defined as a way to express the proportions or rates in terms of a "relative-scale" out of 100,
We know that, 15% of "x" equals 20% of "y".
Mathematically, this can be expressed as,
0.15x = 0.20y, ...because 15% = 0.15 and 20% = 0.20;
To find what percentage of x is y, we need to express "y" as a percentage of "x".
On solving further,
We get,
⇒ 0.15x = 0.20y,
⇒ y = (0.15x)/0.20,
⇒ y = 0.75x
It is read as "y" is read as 75% of "x".
Therefore, "y" is 0.75 times "x", or 75% of "x", Option(c) is correct.

each stack of bricks weighs 163.2 pounds. So the answer is D) 163.2 pounds. we need to form equation to solve this
what is equation ?
An equation is a mathematical statement that shows the equality between two expressions. It consists of two sides, a left-hand side (LHS) and a right-hand side (RHS), that are separated by an equal sign (=). An equation tells us that the expressions on both sides have the same value or are equivalent.
In the given question,
If there are 20 stacks with an equal number of bricks on them, let's call the number of bricks on each stack "x". Then the total number of bricks is:
total number of bricks = 20 stacks × x bricks/stack = 20x bricks
We are also told that the total weight of all the bricks is 3,264 pounds. Let's call the weight of each brick "w". Then the total weight is:
total weight = number of bricks × weight per brick = (20x) bricks × w pounds/brick
We want to find the weight of each stack of bricks, which is equal to the weight of a certain number of bricks. Let's call this weight "s". Then we have:
s pounds/stack = x bricks/stack × w pounds/brick
We can solve for "s" by using the two equations above:
total weight = (20x) bricks × w pounds/brick = 3,264 pounds
s pounds/stack = x bricks/stack × w pounds/brick
Dividing the first equation by 20x, we get:
w pounds/brick = 3,264 pounds ÷ (20x) bricks/stack = 163.2 pounds/stack
Substituting this into the second equation, we get:
s pounds/stack = x bricks/stack × 163.2 pounds/stack
Dividing both sides by x, we get:
s pounds/stack ÷ x bricks/stack = 163.2 pounds/stack
Simplifying, we get:
s pounds/brick = 163.2 pounds/stack
Therefore, each stack of bricks weighs 163.2 pounds.
So the answer is D) 163.2 pounds.
