What is the algebraic expression for
the following word phrase?
three-fourths of a number

Answer:

Step-by-step explanation:

You want to see two other ways to write the ratio 3:8.

A ratio is a way of saying that some number of one thing is always associated with some (often different) number of another thing. The two things may or may not be measured with the same units, and may or may not refer to parts of the same object.

Here, we're concerned with how we write a ratio. One way is shown in the problem statement:

  3 : 8 . . . . . . . . using a colon

Two other ways to write the same ratio are ...

  3 to 8 . . . . . . using the word "to"

  3/8 . . . . . . . . using a fraction bar

__

Additional comment

A ratio is in "simplest form" if the numbers involved are mutually prime (have no common factors).

Sometimes an extended ratio is useful for specifying the relationship between more than two measures, for example, 3 : 8 : 5.

Step-by-step explanation:

The slope Intercept and the standard form of the equation are y = -1/2x - 3 and x + 2y = -6

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

y= -3 and x=-6

The above represent the y and the x intercepts

i.e.

y-intercept = -3

x-intercept = -6

A linear equation is represented as

y = mx + c

Where

c = y-intercept = -3

So, we have

y = mx - 3

At x-intercept = -6, we have

y = 0

So, we have

0 = m(-6) - 3

This gives

m = -1/2

So, we have

y = -1/2x - 3 --- slope-intercept form

Multiply through by 2

So, we have

2y = -x - 6

Rewrite as

x + 2y = -6 ----- standard form

Hence, the slope Intercept and the standard form of the equation are y = -1/2x - 3 and x + 2y = -6

The P-intercept of the function P(x) is 0.

The n -intercepts of the function are n = 0, -3 and -7

We are given the function;

P(n) = 3n⁴ + 30n³ + 63n²

Now, the P intercept of the function P(n) will occur when n = 0. Thus;

P(0) =  3(0)⁴ + 30(0)³ + 63(0)²

P(0) = 0

Thus, the P intercept of the function P(x) is 0.

Now, the n-intercept will be the roots of the given function P(x). Thus;

3n⁴ + 30n³ + 63n² = 0

n²(3n² + 30n + 63) = 0

Thus;

n² = 0 or 3n² + 30n + 63 = 0

Step-by-step explanation:

this is practically a cylinder.

the volume of a cylinder is

ground area × height = pi×r² × height.

r being the radius (half of the diameter).

so, we have here

V = pi×10² × 13 = pi × 100 × 13 = 1300pi =

= 4,084.07045... cm³

1 liter = the content of a cube with 10 cm side length.

10×10×10 cm³ = 1000 cm³ = 1 liter.

the pan has a volume of 4,084.07045... cm³, so, yes, it has the capacity of 4 liters as 4×1000 cm³ (and a little bit extra).

The image of 3 and the image of -2 are 2 and 7, respectively

The equation of the function is given as

f(x) = x^2 - 2x - 1

To determine the image of 3 and the image of -2, we set x to the following values

x = 3 and -2

Substitute x = 3 and -2 in the equation f(x) = x^2 - 2x - 1

So, we have

f(3) = (3)^2 - 2(3) - 1 = 2

f(-2) = (-2)^2 - 2(-2) - 1 = 7

Hence, the image of 3 and the image of -2 are 2 and 7, respectively

Step-by-step explanation:

The co-ordinates of the image after translation are R"(2,1),S"(-1,7) and T"(2,7).

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

When a point is rotated 90° counter clockwise, the co-ordinates of the point say A(x ,y) changes to A"(y,-x).

The given co-ordinates are:  R(-7, - 5), S(-1,- 2), and T(-1.- 5 ).

So when this co-ordinates are translated by rotating 90° counterclockwise.

R(-7, -5) →R'(5,-7)

S(-1,- 2) →S'(2,-1)

T(-1.- 5) →T'(5,-1)

Now the figure is translated 3 units left and 8 units up the new co-ordinates is given by (x-3,y+8).

So when this co-ordinates are translated the new co-ordinates are:

R'(5,-7)→R"(2,1)

S'(2,-1)→S"(-1,7)

T'(5,-1)→T"(2,7)

Check the picture below.

The solution is, the combined volume of the boxes is 180 unit cube.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

from the given diagram, we get,

there is two boxes in the diagram.

now, we have to find the combined volume.

here, we get,

the boxes are cuboids.

we know that,

Volume of  cuboid = length * width * height

V = l*w*h

here, we get, from the figure,

for 1st box, l = 3, w = 5 , h = 8

so, V  = 3 * 5 * 8 = 120

and, for 2nd box, l = 4, w = 5, h = 3

so, V = 4*5*3 = 60

we get, the combined volume 120 + 60 = 180

Hence, The solution is, the combined volume of the boxes is 180 unit cube.

The rug will have dimension of 8ft. wide and 22ft. long.

Dimensions of room :

Wide (w) = 18 ft.

Long (l) =  32 ft.

Area of the room = l × w

                            = 32 × 18 = 576 ft²

Cynthia wants to leave a uniform strip of floor around the rug.

Let the width of the rug = x ft.

Then the dimensions of the rug will be = (18- 2x)ft. × (32- 2x)ft.

Area of the rug = (18 - 2x) × (32 - 2x) ft²

176 = (18 - 2x) × (32 - 2x)

176 = 576 - 36x - 64x + 4x²

  4x² - 100x + 400 = 0    ( Divide the equation by 4 )

      x² - 25x + 100 = 0  

x² - 20x - 5x + 100 = 0

x(x - 20)  -5(x - 20) = 0

       (x - 20) (x - 5) = 0

            x = 20, 5

If we take 20 as x then it will become a negative number when we will substract it from dimensions of the rug.

Therefore, The width of the rug  will be 5 ft.

Thus, The Dimension of the rug = (18- 2x)ft. × (32- 2x)ft.

                                                   = (18 - 10) × (32 - 10)

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the graph of any quadratic function is parabolic because it is a u-shaped curve. For the given quadratic function, the graph is a upward parabola because the coefficient of x² is positive.

A tip in sales is an added monetary contribution to the worker responsible for your bill. Tips are usually in percentage form and represent a portion of the total before you add a tip.

To find a tip in sales, convert the percentage to a decimal and then add 1 to that decimal. Finally, multiply the total by this sum.

To solve, first convert the percentage into a decimal by dividing by 100.

[tex]\displaystyle \frac{10}{100}[/tex]

[tex]0.1[/tex]

Then, add 1 to this quotient.

[tex]1+0.1 =1.1[/tex]

The total cost to the nearest cent is $22.00 when haircut is $20 and tip is 10%.

To find the total cost, we need to add the cost of the haircut and the tip amount.

Given:

Haircut cost = $20

Tip percentage = 10%

First, calculate the tip amount:

Tip = (10/100) × Haircut cost

Tip = (10/100) × $20

Tip = $2

Add the haircut cost and the tip amount to find the total cost:

Total cost = Haircut cost + Tip

Total cost = $20 + $2

Total cost = $22
