Answer: 72 cubic inches
Step-by-step explanation:
The formula for the volume of a cone: [tex]\dfrac{1}{3}\pi r^{2}h[/tex]
Formula for the volume of a cylinder: [tex]\pi r^{2}h[/tex]
We are given that a cylinder should fit exactly inside the cone
Upon comparing the two equations above, we get:
[tex]$$Volume of cone = \dfrac{1}{3}\text{Volume of cylinder}[/tex]
Since we are given the volume of cone is 24 cubic inches, we can write down the below:
[tex]24 = \dfrac{1}{3}\text{Volume of cylinder }\\ \text{Volume of cylinder = 72 cubic inches}[/tex]
Therefore, we can conclude that if the volume of the cylinder is 72 cubic inches, then the cone with volume of 24 cubic inches can fit exactly in.

[tex]V_{cylinder}=72\:in^3[/tex]
Step-by-step explanation:
[tex]V_{cone}=24\: in^3[/tex] (Given)It is given that: Cone fits exactly inside the cylinder.[tex]\implies V_{cylinder}=3*V_{cone}[/tex][tex]\implies V_{cylinder}=3*24[/tex][tex]\implies V_{cylinder}=72\:in^3[/tex]Quick please!!! Buford, the farm hand, is preparing feed for

90% corn to optain a 30-pound bag containing
80% corn. How many pounds of the 50% bag
should he use? (write your answer as a
decimal.)
Buford should use 7.5 pounds of the 50% corn bag.
How do we solve a system of linear equations from word problems?A system of linear equation is an equation containing two different equations with variables and the coefficient.
From the given information, let:
The weight of the bag containing 50% corn be = xThe weight of the bag containing 90% corn be = ySp, we can a system of a linear equation that says:
x + y = 30
0.5x + 0.9y = 0.8(30)
Using elimination method
x + y = 30
-
x - 1.8y = -48
0 - 0.8y = -18
y = 18/0.8
y = 22.5
From x + y = 30
x = 30 - 22.5
x = 7.5
Therefore, we can conclude that he should use 7.5 pounds of the 50% corn bag.

What is Quadratic Equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
Here, given equation:
(x+2)(x+3) = 12

Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y

O Write the points where the graphs of the equations intersect the x-axis.
O Write the points where the graphs of the equations intersect the y-axis.
O Add the equations to eliminate k.
O Multiply the equations to eliminate b.
Answer: Add the equations to eliminate k
Step-by-step explanation:
Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.

Sarah’s company sells bracelets and rings. Her first customer buys 3 bracelets and 10 rings, spending a total of $48. Her second customer buys 7 bracelets and 4 rings, spending a total of $54. How much does Sarah charge for one bracelet?
Please select the best answer from the choices provided
A. $3.00
B. $6.00
C. $12.00
D. not enough information
Sarah charges $6.00 for one bracelet.
We know that a collection of one or more linear equations containing the same variables is known as a system of linear equations in mathematics.
Let Sarah charges $x and $y for one bracelet and one ring respectively.
Since her first customer spends $48 on 3 bracelets and 10 rings, we can write it as
3x + 10y = 48 ...(1)
Since her second customer spends $54 on 7 bracelets and 4 rings, we can write it as
7x + 4y = 54 ...(2)
Now, we have to solve this system of linear equations.
Multiplying (1) by 2, 6x + 20y = 96 ...(3)
Multiplying (2) by 5, 35x + 20y = 270 ...(4)
Subtracting (3) from (4), 35x + 20y - 6x - 20y = 270 - 96
i.e. 29x = 174
i.e. x = 174/29 = 6
Therefore we can conclude that Sarah charges $6 for one bracelet. Option B is correct.

What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
Given two points of the line AB, where the coordinates of point A are (8,0) and the coordinates of point B are (3,7). Now, the slope of the equation can be written as,
m = (0-7)/(8-3) = -7/5
Substitute any one of the points in the equation,
y = -(7/5)x + c

What is a graph?A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as y = mx + c.
Given equation;
y + 2 = (x+2)
Rearrange the equation;
y + 2 = x+ 2
