GEOMETRY The combined volume of a cube and a cylinder is 1000 cubic inches. If the height of the cylinder is
twice the radius and the side of the cube is four times the radius, find the radius of the cylinder to the nearest tenth
of an inch

Answers

Answer 1

The radius of the cylinder with a combined volume of 1000 cubic inches is 2.4 inch

What is an equation?

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let r represent the radius of the cylinder/cone.

For the cylinder:

Volume = π * radius² * height

but height is twice the radius, height = 2r, hence:

Volume = π * r² * 2r = 2πr³

For the cube:

Volume = side³

but side is four times the radius, side = 4r, hence:

Volume = (4r)³ = 64r³

The combined volume of a cube and a cylinder is 1000 cubic inches, hence:

1000 = 2πr³ +  64r³

r³(2π + 64) = 1000

r³ = 1000/(2π + 64)

r³ = 14.228

r = 2.4 inch

The radius is 2.4 inch

The linear equation that is represented in the table is:

y = 3*x + 2

How to write the linear equation?

A general linear equation can be written in the form:

y = m*x + b

Where m is the slope and b is the y-intercept.

First, notice that on the table we can see the point (0, 2), then the y-intercept of the linaer function is b = 2

Then we can write:

y = m*x + 2

Now we can use any other point on the table to find the value of the slope m.

Using the second point (1, 5),replacing the values we will get:

5 = m*1 + 2

Solving for m, we will get:

5 = m + 2

5 - 2 = m

3 = m

Then the linear equation is:

y = 3*x + 2

a) S=24 and T=81
b) S = -24 and T = -81.
(c) S = -24 and T=81
d) S=24 and T=-81

Answers

The evaluation of the equation in the question for the number of solutions is as follows;

2) The values of S and T for which the equation Sx + 81 = -24x + T have infinitely many solutions is S = 24 and T = -81

c. S = 24 and T = -81

What is an equation?

An equation is a statement of equivalence of two expressions.

The specified equation is presented as follows;

S·x + 81 = -24·x + T

The equation will have infinitely many solutions when both sides of the equation refer to the the sam line

The power of x on both sides of the equation is one, therefore, both expressions on the left and right side of the equation refer to linear relationships

The graph of two lines are the same if they have the same slope and the same y-intercept.

The slope of the expression on the left = S

The y-intercept of the expression on the left = 81

The slope of the expression on the right = -24

The y-intercept of the expression on the right = T

When both sides refer to the same line, we get;

S = -24, and T = 81

Therefore, both sides of the equation refers to the same line and therefore have infinitely many solutions when S = -24 and T = 81.

The correct option is option c

(c) S = -24 and T = 81

the vertical spread of the data points about the regression line is measured by the y-intercept.

Answers

The standard error of the estimate measures the vertical spread of the data points around the regression line.

The standard error of the estimate, a measurement of the average deviation of errors, is the difference between the y-values predicted by the multiple regression model and the y-values in the sample. This illustrates the precision of the regression model as well as the range of variation surrounding the estimated regression line.

The standard error of the estimate can be used to produce a confidence interval for the actual regression coefficient. The standard error is calculated by multiplying the standard deviation by the square root of the sample size. The standard deviation of the errors/residuals is the standard error of the estimate for the regression model.

BRAINLIEST EASY PROBLEM!!!!!!!!!!! 7th grade) find x and y.

Answers

Answer:

x = 20

y = 20

Step-by-step explanation:

In the given triangle, we can deduce that angle x is congruent to angle y using the Isosceles Triangle Theorem. Hence, we can construct the equation xº = yº.

We also know that the measures of the interior angles of a triangle add to 180º. Hence, we can construct the equation xº + yº + 140º = 180º.

We now have a system of equations, and since we already have an identity for xº (and also for yº), we can solve the system using the substitution method.

xº + yº + 140º = 180º

↓ substituting xº for yº

xº + xº + 140º = 180º

↓ subtraction 140º from both sides

2xº = 40º

↓ dividing both sides by 2

xº = 20º

↓ removing degree sign from both sides

x = 20

Now that we have solved for x, we have also essentially solved for y, as plugging this x-value into the equation xº = yº will just yield:

20 = y

y = 20

The solution of the simultaneous equations using target matrix are; x = 51/37 and y = 33/37

How to use matrix to solve simultaneous equations?

The target variable is defined as the variable whose values are modeled and predicted by other variables.

We are given the simultaneous equations as;

5x - y = 6

2x + 7y = 9

In matrix form, it is expressed as;

5 -1 6

Thus;

x = 51/37

Plugging in 51/37 for x in eq 1 gives;

5(51/37) - y = 6

Multiply through by 37 to get;

How much of a 14% ethanol fuel mixture should be mixed with 8 gal of 3% ethanol fuel mixture to get a mixture that is 12% ethanol?

(blank) gal of 14% ethanol solution is needed to produce a 12% ethanol solution.

Answers

Answer:

Step-by-step explanation:

A = x 14%=.14x

B=8 (4%)=.04(8)

  =8x   12%= .12*8x

.14x+.04(8)=.12(8x)

.14x+.32=96x-.14x

.32=.82x/x

.32/.82=.39

The amount of 14 % of ethanol that needs to mixed is A = 36 gallons

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

14% ethanol fuel mixture should be mixed with 8 gal of 3% ethanol fuel mixture to get a mixture that is 12% ethanol

So , the equation is

A ( 14 % ) + ( 8 ) ( 3 % ) = ( A + 8 ) ( 12 % )

On simplifying , we get

14A + 24 = 12A + 96

Subtracting 12A on both sides , we get

2A + 24 = 96

Subtracting 24 on both sides , we get

2A = 72

Divide by 2 on both sides , we get

A = 36 gallons

Therefore , the value of A is 36 gallons

Hence , the equation is A = 36 gallons

Answers

The shape that results from a plane passing through a cone that is perpendicular to the base is option B: Circle.

What is the Circle about?

When a plane passes through a cone perpendicular to the base, it intersects the cone at a circle. This is because the plane is cutting the cone at a 90-degree angle to the base, and so it is cutting through the circular cross-section of the cone.

Therefore, If the plane were to be tilted or angled, the shape of the intersection would be an ellipse, which is a flattened circle. This is because an ellipse is the shape that results when a plane intersects a cone at an angle that is not perpendicular to the base.

If the only difference between two triangles is their size (and perhaps the need to rotate or flip one), but not their shape, then they are similar.

In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "≅"

If ΔABC and ΔXYZ are similar triangles then

∠A = ∠X, ∠B = ∠Y, and ∠C = ∠Z  

Here we have

ΔXYZ and ΔLMN are similar triangles

=> ∠X = ∠L,  ∠Y = ∠M, and  ∠Z = ∠N    

From the given figure,

=> ∠X = ∠L = 25°

=> ∠Y = ∠N = 115°

=> ∠Z = ∠M    

From ΔLMN      

=> ∠L + ∠M + ∠N = 180°  

=> 25° + ∠M +115° = 180°
