What is a cone?
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
We are given that radius of the cone as 5yd and slant height as 13yd
We first find the height using pythagoras theorem
Let height be h
by Pythagoras theorem we have
[tex]r^{2}+h^{2}=13^2\\ 5^2+h^2=169\\ h^2=144\\h=12[/tex]
Height of the cone is 12yds
Now volume of the cone is given by
[tex]V=[/tex]π[tex]r^{2}\frac{h}{3}[/tex]
Substituting the values in the equation we get
[tex]V=100[/tex]π yd^3
Now we find the surface area
The formula for surface area is
[tex]A=r(r+\sqrt{r^2+h^2} )[/tex]π
Substituting the values in the equation we get
[tex]A=90[/tex]π yd^2
Hence the surface area of the cone is 90π yd^2
And the volume of the cone is 100π yd^3

x = 41/6 is value of x in transversal lines.
What are transversal lines?
A line that crosses two lines in the same plane at two different geometric locations is referred to as a transversal. Different sorts of angles in pairs, including successive internal angles, corresponding angles, and alternate angles, are produced by a transversal intersection with two lines.A line that crosses other lines is known as a transversal. When transversals intersect parallel lines, such as the two railroad tracks, we often operate with them.( 12x + 1)° = 2
2 = 83°
( 12x + 1)° = 83°
12x° + 1° = 83°

Answer: The equation is written as: " 7x + 28 = 8 − 3x " .
The value for x , when the equation is solved, is: " -2 ."
Step-by-step explanation:
Let the "unknown number" be represented by the variable, x ;
7 (times) the [sum of: (x + 4)] ; (is the same as): 8 [decreased by]:
3(times)x ;
Rewrite: " 7(x + 4) = 8 − 3x ". This is the written expression.
____
Now, if we wish to "solve for x" ;
Let's examine the 'left-hand side' of the equation:
7(x + 4) ;
Note the 'distributive property' of multiplication:
a(b + c) = ab + ac ;
____
So: 7(x + 4) = 7*x + 7*4 = 7x + 28 ;
Now, let's write the entire equation:
7x + 28 = 8 − 3x ;
Let's add 3x , and subtract 8 ; from Each Side of the equation:

→ 7x + 3x + 28 − 8 = 8 − 3x + 3x;
to get:
10x + 20 = 0 ;
Now: Subtract 20 from Each Side of the equation:
10x + 20 − 20 = 0 − 20 ;
to get:
10x = -20 ; Now, divide both sides of the equation by 10 ;
to isolate x on one side of the equation; & to solve for x :

Step-by-step explanation:
y is inversely proportional to the square root of x.
When x = 16, y = 10.
What does x equal when y = 8?
Answer:
x = 25 when y = 8
Step-by-step explanation:
If y is inversely proportional to square root of x we write it as
[tex]y \propto \dfrac{1}{\sqrt{x}}[/tex]
This is also equivalent to
[tex]y = k \dfrac{1}{\sqrt{x}} \;\;\;\;\ \text{ [1]}[/tex]
where k is a constant known as the constant of proportionality
Given y = 10 when x = 16 we can find k by substituting for y and x in [1]
[tex]\rightarrow 10 = k\dfrac{1}{\sqrt{16}}\\\\\rightarrow 10 = k \dfrac{1}{4}\\\\\drightarrow 40 = k \:\:\:\: \text{by multiplying both sides by 4}\\\\\text{which can be written as }\\\\k = 40\\[/tex]
So constant of proportionality k = 40
To find x when y = 8, substitute y and k in [1] to get
[tex]y = k \dfrac{1}{\sqrt{x}}\\\text{Multiply both sides by \sqrt{x} and divide by y at the same time to get}\\\\\sqrt{x} = \dfrac{k}{y}[/tex]
Dividing both sides by y and multiplying by √x gives us
[tex]\sqrt{x} = \dfrac{k}{y}\\\\\text{Substituting k = 40, y = 8}:\\\\\sqrt{x} = \dfrac{40}{8}\\\\\sqrt{x}= 5\\\\\text{Squaring both sides: }\\\\(\sqrt{x})^2 = 5^2\\\\x = 25 \;\;\;\text{since $(\sqrt{x})^2$ = x}[/tex]
The answer is
x = 20
Formulate y=k/x based on the following criteria.
Replace: 10= k/16
Change the sides so that k/16 = 10.
Subtract the coefficient of the variable from both sides of the equation: k = 10×16
Determine the quotient or product: k = 160
Replace with y = 160/x.
Replace with: 8 = 160/x
The denominator cannot be zero if the fraction is defined: as x ≠ 0
As the domain, append the inequality: 8= 160/x, x≠0
Divide the common denominator by both sides of the equation: 8x = 160x/x, x≠0
8x=160x/x, where x ≠ 0. Reduce the fraction.
By the variable's coefficient, multiply both sides of the equation (x=160÷8, x ≠ 0).

Step-by-step explanation:
I am basing this off of your straight line that you drew.
Slope is found by using [tex]\frac{rise}{run}[/tex] . This means that you change in your y-axis divided by change in your x axis.
This can also be modeled by Δy/Δx
I used point (0,0) and the peak of the slope (100,200)
Your line starts at 0 and rises 200 and runs to the right 100.
Thus, you can write:
y = [tex]\frac{200}{100}[/tex] x

Answer:
x = 45
y = 20
Step-by-step explanation:
Since the two horizontal lines are parallel
angles with measures of 6y and 3y are supplementary angles and add up to 180°
So 6y + 3y = 180
9y = 190
y = 20
Similary 2x and 90 are supplementary angles
2x + 90 = 180
2x = 90°
x = 45
Answer:
x=45 y=20
Step-by-step explanation:
you can tell x is 45 because is is a right angle and those are 90 degrees.
9y+180=360 360 because that is the sum of all the angles added up in a quadrilateral.
9y=180

Jenna is making a scarf. She needs 23 /4 feet of yarn. Each yarn bundle is 11 1/2feet. How many bundles does Jenna need? How much will be left over?
Given:
The length of yarn needed, l=23 1/4 feet.
The length of a yarn bundle, L=11 1/2 feet.
The number of bundles of yarn needed can be calculated as,
[tex]\begin{gathered} n=\frac{l}{L}=\frac{23\text{ }\frac{1}{4}}{11\frac{1}{2}} \\ n=\frac{\frac{23\times4+1}{4}}{\frac{11\times2+1}{2}} \\ n=\frac{\frac{93}{4}}{\frac{23}{2}} \\ n=\frac{93}{4}\times\frac{2}{23} \\ n=\frac{93}{2}\times\frac{1}{23} \\ n=\frac{93}{46} \\ n=2\frac{1}{46} \end{gathered}[/tex]Therefore, 3 bundles is needed by Jenna to make the scarf.
The part of leftover yarn is,
[tex]\begin{gathered} N^{}=3-2\frac{1}{46} \\ =3-(2+\frac{1}{46}) \\ =1-\frac{1}{46} \\ =\frac{46-1}{46} \\ =\frac{45}{46} \end{gathered}[/tex]Hence, 45/46 part of a bundle of yarn will be left.
Now, the length of leftover yarn is,
[tex]\begin{gathered} l^{\prime}=N\times L \\ =\frac{45}{46}\times11\frac{1}{2} \\ =\frac{45}{46}\times\frac{11\times2+1}{2} \\ =\frac{45}{46}\times\frac{23}{2} \\ =\frac{45}{2}\times\frac{1}{2} \\ =\frac{45}{4} \\ =11\frac{1}{4}\text{feet} \end{gathered}[/tex]Therefore, 111/4 feet of yarn will be left.
Which graph best represents the solution set to this system of inequalities?
x+y <1

The graph of the inequality (x + y >1), will be:
{(x^2+(y-1)^2-0.05)((x-1)^2+y^2-0.05)(x+y-1)=0 [-10, 10, -5, 5]} and we can shade right-side of the line.
As per the question statement, we are supposed to graph the inequality
x + y >1. So, first we solve for two points as an equation instead of an inequality to find the boundary line for the inequality.
For x = 0, y = 1 or (0,1)
For y = 0, x = 1 or (1,0)
So now we can graph the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.
The boundary line would be solid because the inequality contains "or equal to" clause.
Graph: {(x^2+(y-1)^2-0.05)((x-1)^2+y^2-0.05)(x+y-1)=0 [-10, 10, -5, 5]}
We can shade right-side of the line.
Because the inequality operator lacks a "or equal to" phrase, the boundary line will be altered to a dashed line.

The expansion of ( 2x - y⁵)² using algebraic identity, as a polynomial is 4x² - 4xy⁵+ y¹⁰
What are algebraic identities?Algebraic identities are the identities which aids in solving products or powers of algebraic expressions. Most common identities are :
(a+ b)² = a² + 2ab + b²
(a- b)² = a² - 2ab + b²
a² -b² = (a+ b) (a- b), where a and b can be variable or constants or algebraic expressions.
For expanding (2x - y⁵)²
Use identity (a-b)² = a²-2ab+b², let a = 2x and b = y⁵
Then, ( 2x - y⁵)² = (2x)² - 2(2x)( y⁵) + (y⁵)²
⇒ ( 2x - y⁵)² = 4x² - 4xy⁵+ y¹⁰

Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form. One of the formulas used to get a line's equation is the slope-intercept formula. Y = mx + b is the slope-intercept formula for a line with slope m and y-intercept b. Any point on the line is (x, y) in this case.
Given,
A basket with 4 apples weighs 2 pounds.
Slope intercept form:
y = mx + b
Equation:
2 = 4m +b ..(1)
A basket with 12 apples weighs 4 pounds
4 = 12m + b ... (2)
Solving,
2 = 4m + b
4 = 12m + b
4 = 8m
Divide the second equation by 8:
2 = 4m + b
m = 0.25
b = 1
The relationship between x and y is y = 0.25x + 1.
