Answer:

$27

Step-by-step explanation:

We find 50% of $18 and add it to $18.

50% of $18 = 5/100 × $18 = 0.5 × $18 = $9

Today, it is worth $9 more.

$18 + $9 = $27

After the dilation, the new volume of the cube is 125 times the original volume of the cube.

Remember that for a cube of sidelength S, the volume is written as:

V = S^3

If we apply a dilation of scale factor 5 to the cube, then the new sidelength of the cube is 5*S

Replacing that in the volume formula we will get the volume of the dilated cube, it is:

V' = (5*S)^3

V' = 5^3*S^3

V' = 125*S^3

Where S^3 is the original volume, so we can write:

V' = 125*V

So the new volume is 125 times the original volume.

Step-by-step explanation:

-12 < -3x - 15 <= 36 | add 15 everywhere

3 < -3x <= 51 | divide by 3 everywhere

1 < -x <= 17 | multiply by -1 everywhere

-1 > x >= -17

or

-17 <= x < -1

remember that with every multiplication or division of a negative number the orientation of the inequality signs flip.

the same happens, of course, when we exchange the upper and lower limits from left to right and right to left, so that the smaller number is on the left, and the larger number on the right (yes, -1 is larger than -17).

The amount of sugar that both companies would charge the same is 20 tons.

The cost when the two companies would charge the same is $9010.

The linear equation that represents the total charge of the companies : cost to rent truck + (ton of sugar x cost per ton)

The linear equation that represents the total charge of the first company : $5500 + ($175 x s)

$5500 + $175s

The linear equation that represents the total charge of the second company : $4995 + ($200.75 x s)

$4995 + $200.75s

When the two companies charge the same, the two linear functions above would be equal.

$4995 + $200.75s  = $5500 + $175s

In order to determine the value of s, take the following steps:

200.75s - 175.50s = $5500 - $4995

25.25s = 505

s = 505 / 27.25

s = 20

In order to determine when the cost of the two companies would be the same, substitute for s in either of the above linear functions.

$5500 + $175.50(20)

$5,500 + 3510 = $9010

Answer:

biology = 255 ; sociology = 192

Step-by-step explanation:

b + s = 447

s = b - 63

b + b - 63 = 447

2b = 447 + 63

2b = 510

2/2 b = 510/2

b = 255

s = 255 - 63

s = 192

Answer: 192 sociology textbooks,  255 biology textbooks

Step-by-step explanation:

Let the number of biology be x, and the number of sociology be x

The number of the sociology textbook is x+63

So the equation is

x + x + 63 = 447

2x = 384

x= 192 sociology textbooks

To find the number of biology textbooks, just take 447- 192 = 255 biology textbooks

What is function?

A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The set X is known as the function's domain, and the set Y is known as the function's codomain.

Let, the function h is defined by the rule,

h(x) = 2x - 3

We have to complete the function table.

x = -4  ⇒  h(-4) = 2(-4) - 3 = -8 - 3 = -11

x = 0  ⇒  h(0) = 2(0) - 3 = -3

x = 2  ⇒  h(2) = 2(2) - 3 = 4 - 3 = 1

x = 4  ⇒  h(4) = 2(4) - 3 = 8 - 3 = 5

Buy the land !all angles will be greater than 30 °

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circular functions) that make up trigonometry.

A branch of mathematics called trigonometry examines connections between triangles' sides and angles. Due to the fact that every straight-sided shape can be decomposed into a group of triangles, trigonometry can be found throughout all of geometry.

From the ratio gotten, the total cost of the pepper will be $129.90.

How to solve a ratio

Since the students planted 8 tomato plants and 16 pepper plants in a school garden. The ratio will be:

= 8/16 = 1:2

This year, the students planted 15 tomato plants, the number of pepper will be:

= 15 × 2 = 30

Since pepper plants cost $4.33 each, the total cost will be:

= 30 × $4.33

= $129.90

The function operation h(8) - f(-7) of the functions f(x) = -4x+1, and h(x) = 19-3x is -34.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, solve for the output value of h(8) by replacing x with 8 and simplify.

h(x) = 19 - 3x

h(8) = 19 - 3(8)

h(8) = 19 - 24

h(8) = -5

Next, solve for the output value of f(-7) by replacing x with -7 and simplify.

f(x) = -4x + 1

f( -7 ) = -4( -7 ) + 1

f( -7 ) = 28 + 1

f( -7 ) = 29

Now, replace the function designators with the actual output values.

h(8) - f(-7) =  -5 - ( 29 )

h(8) - f(-7) =  -5 - 29

h(8) - f(-7) =  -34

Therefore, the output of the function operation h(8) - f(-7) is -34.

The equations, y=5x, b = 1/2 a, m=5n are direct variations.

A sort of proportionality known as "direct variation" occurs when one quantity directly changes in response to a change in another quantity. This suggests that if one quantity increases, the other quantity will also increase proportionately. Similar to the last example, if one quantity declines, the other amount also declines. The link between direct variation and the graph will be linear, resulting in a straight line.

We know that any equation, which can be expressed in the form of y=kx, can be called a direct variation.

y = 5x is in the form of y = kx, where k =5, hence this is a direct variation

y = 2x + 1 is not in the form of y = kx, hence this is not a direct variation

xy = 3 is not in the form of y = kx, hence this is not a direct variation

b = 1/2 a is in the form of y = kx, where k =1/2, hence this is a direct variation

y = 2/x is not in the form of y = kx, hence this is not a direct variation

m = 5n is in the form of y = kx, where k =5, hence this is a direct variation

Thus, y=5x, b = 1/2 a, m=5n are direct variation

Answer:

  B.  False

Step-by-step explanation:

You want to know if (x -2) is a factor of 5x² -6x +4.

There are a couple of ways you can determine whether (x -2) is a factor. One is to look at the polynomial value at x=2:

  5x² -6x +4 = (5x -6)x +4 = (5(2) -6)(2) +4 = 4(2) +4 = 12

The value is not 0, so (x -2) is not a factor.

Another way to tell is to determine what the other factor would be.

The product of roots is the ratio c/a = 4/5 in the polynomial. If 2 is a root, then (4/5)/2 = 2/5 is the other root. That would mean the factorization of the polynomial is ...

  (5x -2)(x -2) = 5x² -12x +4 . . . . . . not the same polynomial

The polynomial 5x² -6x +4 does not have a factor (x -2).

The graph of the polynomial has no x-intercepts, so (x -2) cannot be a factor.

On solving the provided the question, we got that - f(x) = 7/3[x - (2)] [x - (-1)] (x +3) is the equation which is formed.

An equation can be defined in a variety of ways. The definition of an equation in algebra is a mathematical statement proving the equality of two mathematical expressions.

Gives zeroes are -

-3, -1 and 2

and it passes through (0, -14)

Constructing a function from a product of factors containing the zeros, with an unknown coefficient

f(x) = a [x - (2)] [x - (-1)] (x +3)

with a ≠ 0.

f(x) = a(x -2)(x + 1)((x +3)

Use f(0) = -14 to find a.

-14 = a(-2)(1)(3) = -6a

a = 7/3

The inequality for the number line show is x<5.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We can see that the inequality starts from 5 moves towards 2.

As, the starting of number line have open dot which shows we cannot include 5.
