Answer:

15. x = 4

16. x = 7

Step-by-step explanation:

15.

CD/ ED = DG / DF

48 / (5x - 2) = 40 / (2x + 7)

48 (2x + 7) = 40 (5x - 2)

96x + 336 = 200x - 80

200x - 96x = 336 + 80

104x = 416

x = 4

16.

ST / PL = TU / LM

(x + 1) / 72 = (2x - 3) / 99

99 (x + 1) = 72 (2x - 3)

99x + 99 = 144x - 216

144x - 99x = 99 + 216

45x = 315

x = 7

In four digits number, if 5 is ones place, then the value is 5. It 5 is on tens place then the value will be 50. If the 5 is on hundred places then value will be 500. If 5 are on thousand places then value will be 5000.

In the given question, we have to find the value of underlined 5 in four digit numbers.

As we know that,

Place value labels like tens and ones notify us of a number appear digit's value. More than one digit can be used to create a number. As a result, to better understand the value of each digit, we employ place value labels such as ones, tens, hundreds, and thousands.

As we know that we count the numbers as ones, tens, hundreds and so on.

So if a 4 digit number is given and we have to find the value of underline 5, and then if 5 is ones place, then the value is 5. It 5 is on tens place then the value will be 50. If the 5 is on hundred places then value will be 500. If 5 are on thousand places then value will be 5000.

The parallelism of the linear equations of two lines is clearly shown by the fact that both have the same slope. Due to the fact that they both have a slope of -2, they are parallel.

An equation is said to be linear if the maximum power of the variable is consistently 1.

Another name for it is a one-degree equation.

A linear equation with one variable has the conventional form Ax + B = 0.

In this case, the variables x and A are variables, while B is a constant.

So, there is a degree of 1 in these equations.

Knowing the lines' equation:

ab: 6x + 3y = 9

cd: 4x + 2y = 8

Afterward, write in slope-intercept form as follows:

ab: y = -2x + 3

cd = y = -2x +8

It is evident that both lines have the same slope, demonstrating their parallelism.

Therefore, the parallelism of the linear equations of two lines is clearly shown by the fact that both have the same slope. Due to the fact that they both have a slope of -2, they are parallel.

The length of cable that is needed for the initial rise is; 41 feet.

The given parameters are as shown in the image of the triangle attached.

Where;

A = 28 , a = 25 ft, and b = 20 ft.

Now, if A is acute and a > b, it means that one solution exists. Using the

Law of Sines to find B;

a/sin A = b/sin B

Plugging in the relevant values gives;

25/sin 28 = 20/sin B

sin B = (20 sin 28)/25

sin B = 0.3756

B = sin⁻¹0.3756

B = 22.06°

Due to the fact that the two angles are now known, it means that the angle opposite x is 180 – (28 + 22.06 ) = 129.94 . Using the Law of Sines to find x;

The path  LORAN followed is hyperbolic.

The equation of the hyperbola is x²/8100 + y²/1900 = 1

Given,

These are the coordinates:

(x, y) = (-100, 0)  (100, 0)

The hyperbola's center; (h, k) = (0, 0)

The following is the distance between the center and the focal points:

c = 100

Square both sides;

c² = 10000

The following is the distance between the transmitters and the receiver:

2a = 180

Divide 2 from both sides.

a = 90

Square both sides;

a² = 8100

We possess;

b² = c² - a²

This results in;

b² = 10000 - 8100

b² = 1900

A hyperbola's equation is as follows:

(x - h)²/a²  + (y - k)²/b² = 1

We thus have:

(x - 0)²/8100 + (y - 0)²/1900 = 1

x²/8100 + y²/1900 = 1

Step-by-step explanation:

Define the variables:

The rate of vibration of a string under constant tension varies inversely with the length of the string:

[tex]\boxed{y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x}\quad\text{for a constant $k$}}[/tex]

Given values:

Substitute the given values of x and y into the formula and solve for k:

[tex]\implies 128=\dfrac{k}{24}[/tex]

[tex]\implies k=128 \cdot 24[/tex]

[tex]\implies k=3072[/tex]

Therefore, the equation is:

[tex]y=\dfrac{3072}{x}[/tex]

To find the length of a string that vibrates 64 times per second, substitute y = 64 into the equation and solve for x:

[tex]\implies 64=\dfrac{3072}{x}[/tex]

[tex]\implies x=\dfrac{3072}{64}[/tex]

[tex]\implies x=48[/tex]

Therefore, the length of a string that vibrates 64 times per second is 48 inches.

Define the variables:

The horsepower that a shaft can safely transmit varies jointly with its speed and the cube of the diameter:

[tex]\boxed{y \propto vd^3 \implies y=kvd^3\quad\text{for a constant $k$}}[/tex]

Given values:

Substitute the given values of y, v and d into the formula and solve for k:

[tex]\implies 45=k \cdot 100 \cdot 3^3[/tex]

[tex]\implies 45=k \cdot 100 \cdot 27[/tex]

[tex]\implies 45=2700k[/tex]

[tex]\implies k=\dfrac{45}{2700}=\dfrac{1}{60}[/tex]

Therefore, the equation is:

[tex]y=\dfrac{vd^3}{60}[/tex]

To find the diameter of the shaft in order to transmit 60 hp at 150 rpm, substitute y = 60 and v = 150 into the equation and solve for d:

[tex]\implies 60=\dfrac{150d^3}{60}[/tex]

[tex]\implies 3600=150d^3[/tex]

[tex]\implies d^3=\dfrac{3600}{150}[/tex]

[tex]\implies d^3=24[/tex]

[tex]\implies d=\sqrt[3]{24}[/tex]

[tex]\implies d=\sqrt[3]{8 \cdot 3}[/tex]

[tex]\implies d=\sqrt[3]{8} \sqrt[3]{3}[/tex]

[tex]\implies d=\sqrt[3]{2^3} \cdot \sqrt[3]{3}[/tex]

[tex]\implies d=2\sqrt[3]{3}[/tex]

Therefore, the diameter of a shaft that transmits 60 hp at 150 rpm is 2³√3 inches.

Identifying which variables values result in equality is part of solving a variable equation. The variables for which the equation must be solved are known as unknowns, whereas the unknown values that fulfill the equality are known as equation solutions. A mathematical expression with two equal sides separated by an equal sign is known as an equation. 4 + 6 = 10. We can see 4 + 6 on the left and 10 on the right side of the equal symbol.

We already have,

1) You often purchase a grande cafe latte from Starbucks, which costs $3.65.

This formula is:

Number of days = x

Total cost after x days = 3.65x

2) You spend $300 on an espresso machine and ingredients for lattes, which cost an extra $1.35 per day.

This formula is:

Number of days = x

Total cost after x days = 300 + 1.35x

Now, three days later,

Distributional semantics develops methods for measuring and classifying semantic similarity between language elements.

To quantify and classify semantic relatedness among linguistic items based on their distributional qualities in large samples of language data, distributional semantics is a field of study. The distributional hypothesis captures the fundamental principle of distributional semantics.

The semantic theory of language usage, states that terms used and occurring in comparable situations tend to have similar meanings is the basis for the distributional hypothesis in linguistics. For instance, the words "fire" and "dog" have very different meanings and aren't typically used together in a sentence. However, the terms "dog" and "cat" are occasionally used interchangeably, suggesting that they may have a similar connotation.

The percentage is an abbreviation for 'by the hundred' or 'divide by one hundred.' The percentage, which means 'per 100,' is also used to compare quantities.

Given data:

Ratio of adults to children = 7 : 2

The proportion of children that had sit in the stalls = 4/5

Number of children that had sit in the Circle = 124 children

Number of seats at the theatre = 3,875

Let x represent the number of children, we have;

The number of children in the stalls = (4/5).x

Then the number of children in the circle = x - (4/5).x = 124

Solving this, we get

          x = 620

Given ratio is Number of adults/Number of children = 7:2

                    Number of adults/620 = 7/2

      So the number of adults = 2,170

Total number of peoples = 2170 + 620 = 2790
