The question has missing details; as the dimension of the cone is not given. I will give a general explanation on how to solve a question like this.
The space occupied implies that we calculate the volume of the cone.
The volume of 1 cone is:
[tex]V_1 = \frac{1}{3}\pi r^2h[/tex]
Since there are 5 cone trees, the total amount of space is:
[tex]V =5 * V_1[/tex]
[tex]V = 5 * \frac{1}{3}\pi r^2h[/tex]
Assume the height and the radius of the cone tree are: 6cm and 7cm respectively.
The expression becomes
[tex]V = 5 * \frac{1}{3} * 3.14 * 7^2 * 6[/tex]
[tex]V = 1538.6cm^3[/tex]
Using the assumed dimensions, the amount of space occupied is [tex]1538.6cm^3[/tex]

What is the value of x in this triangle?
Answer:
65
Step-by-step explanation:
Solve: 2.4y - 3.2 = 4
A y = 0.5
B y = 1.6
C y = 2
D y = 3
Answer:
y=3 you have to use PEMDAS
Answer:
y=3
Step-by-step explanation:
Combine multiplied terms into a single fraction
2.4y-3.2=4
12y/5 -3.2=4
Add 3.2 to both sides of the equation
12y/5- 3.2+3.2=4+3.2
Simplify
add the numbers 12y/5=7.2
Solution
y=3
The line l is tangent to the circle with equation x² + y2 = 169 at the point P.
By thinking about the radius or otherwise, determine the gradient of the line l.
Given:
The equation of a circle is
[tex]x^2+y^2=169[/tex]
A tangent line l to the circle touches the circle at point P(12,5).
To find:
The gradient of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(12,5). So, the slope of radius is
[tex]m_1=\dfrac{5-0}{12-0}[/tex]
[tex]m_1=\dfrac{5}{12}[/tex]
We know that, the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times \dfrac{5}{12}=-1[/tex]
[tex]m=-\dfrac{12}{5}[/tex]
Therefore, the gradient or slope of the tangent line l is [tex]-\dfrac{12}{5}[/tex] .
how many zeros are in f(x) = 3x^4 + x + 2
i know its 4... but i dont know how to solve the question
so please help me solve the question and show how there are 4 zeroes
Answer:
The power of the polynomial determines the number of zeroes it has in this case power is 4 so 4 zeroes. Whereas in 5^3+4 it has 3 zeroes as its power is 3. U can find the zero by trial and error method.

Answer:
Line a and Line b are parallel. The slopes are equal
Line b is perpendicular to line c. The slopes are different
Step-by-step explanation:
The standard form of an equation is y =- mx+C
m is the slope
Two lines are parallel if they have the same slope and perpendicular if the product of their slope is -1
For Line a: 4x-3y = 2
Rewrite
-3y = -4x+2
y = 4/3 x - 2/3
Slope of line a is 4/3
Line b: y = 4/3x + 2
mx = 4/3x
m = 4/3
slope of line b is 4/3
Line c = 4y+3x = 4
4y = -3x + 4
y = -3/4 x + 1
Slope of line c is -4/3
Since line a and b have the same slope, they arer parallel
mb * mc = 4/3 * -3/4
mb*mc = -1
Since the product of slope of line b and c is -1, they are perpendiclar

Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
390° terminates in quadrant
Answer:
The answer is below
Step-by-step explanation:
Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
-150° terminates in quadrant
390° terminates in quadrant
Solution:
The x and y axis divides the cartesian plane into four equal parts known as the four quadrants.
Angles between 0° and 90° are in the first quadrant, angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant while angles between 270° and 360° are in the fourth quadrant.
a) Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
b) -150° = 360 - 150 = 210°. Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
c) 390° = 390° - 360° = 30°.
Since 30 degrees is between 0° and 90°, hence it terminates in the first quadrant.
Answer:
a. quadrant III
b. quadrant III

The second question is multiple choice.
1.) Describe how the graph of y=2x is the same AND different from the graph of y=2x-7. EXPLAIN. ?
2. Use the photo for this question! This is a multiple choice question.
What is the equation for the line below (the photo)
Y = 1x + 2
Y = 2x + 1
Y=2x
Y = 1 -2
Question 1: The equations share the same slope, but different y-intercepts.
Question 2: Option B (y = 2x + 1)
Explanations:For Question 1:Both equations are written in slope intercept form.
[tex]y = mx+b\\\\\text{m - slope}\\\text{b - y-intercept}[/tex]
The equations we have are:
[tex]\left \{ {{y=2x} \atop {y=2x-7}} \right.[/tex]
Both equations share the same slope of 2. However, they have different y-intercepts.
y = 2x can be written as y = 2x + 0.
Usually if you only have the slope in your equation then the y-intercept is the origin, or (0, 0).
The second equation's y-intercept is -7. It takes 'b's place.
For Question 2:We are given a graph and we need to find a equation.
According to the graph, the line passes at (0, 1). 1 is the y - intercept.
Since y = 2x + 1 is the only option with 1 as the y - intercept, it should be the correct answer.
I'll do the slope as well to verify our answer.
I will use the points (-1, -1) and (1, 3).
[tex]m=\frac{3-(-1)}{1-(-1)}=\frac{4}{2} =\boxed{2}[/tex]
The correct answer should be [tex]y = 2x+1[/tex].
Hope this helps you.

The volume of a rectangular prism can be found by multiplying the three side lengths. A bookcase in the shape of a rectangular prism has dimensions (b+8) ft, b ft, and (b+3) ft. Find the volume of the bookcase
Answer:
(b³+11b²+24)ft³
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Given the dimension
Length = b+8 ft
Width = b ft
Height = (b+3)ft
Volume of the rectangular prism = b(b+8)(b+3)
Volume of the rectangular prism = b(b^2+3b+8b+24)
Volume of the rectangular prism = b(b^2+11b+24)
Volume of the rectangular prism = b(b^2)+b(11b)+1(24)
Volume of the rectangular prism = b^3+11b^2+24
Hence the Volume of the rectangular prism is (b³+11b²+24)ft³

The perimeter of the triangle is 202cm. Using that find the value of x
Answer:
x = 13
Step-by-step explanation:
3x + 12 + 5x + 16 + 4x + 18 = 202
combine like terms
12x + 12 + 16 + 18 = 202
12x + 46 = 202
-46 -46
12x = 156
divide by 12
x = 13

Add all the sides together (don´t forget parenthesis) Put the x´s with the x´s and the same with the other numbers. The subtract additional numbers from the total. The divide what left from the number in front of the x.
(3x + 12) + (5x + 16) + (4x + 18) = 202
8x + 28 + (4x + 18) = 202
12x + 46 = 202
- 46 -46
12x = 156

∠A and angle B∠ are complementary angles. if m∠A=(4x+6)
∘
and m ∠B = (4x-4)∘
, then find the measure of∠A
Answer:
m∡A = 50°
Step-by-step explanation:
since they are complementary they must equal 90°
4x+6 + 4x-4 = 90
8x + 2 = 90
8x = 88
x = 11
∡A = 4(11)+6 = 44+6 = 50
