solve for x when c-b=1

Answer:

Step-by-step explanation:

the equation of this function has the form y = k/x, and when x = 15 and y = 3, the value of k can be calculated as follows:

3 = k/15, or (by multiplying both sides by 15) k = 45

Then y = 45/x

Answer:

√34

Step-by-step explanation:

To find the distance between two points, you can use the distance formula, which is:

d = √[(x2 - x1)^2 + (y2 - y1)^2]

We can plug in the points (3, 7) and (-2, 10) to get:

d = √[(-2 - 3)^2 + (10 - 7)^2]

We can simplify.

d = √[(-5)^2 + (3)^2]

d = √(25 + 9)

d = √(34)

d =  √34

The point that is -2 on the number line is point B. Option B

We know that the number line can be taken as a representation of the numbers. We ought to know that the numbers that we find on the number line are the numbers that are increasing to the right as shown.

In the question that we have, the task that is before us is that we should be able to locate the point on the number line that has been labelled as -2 on this the point B non the line. This is the point that is read off as -2.

Step-by-step explanation:

Using pythagoras theorem

The measure of BC is 8.486 unit.

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given angle is 45 degree.

Hypotenuse = 12 unit

Answer: 875 people

Step-by-step explanation:

The 375 people seated represent 30% of the total number of people who wanted seats but these ones got them.

This means that the number of people who wanted seats is 70% of the number of people who wanted seats.

Assume the number of people who wanted seats is x:

30% * x = 375

x = 375 / 30%

x = 1,250 people wanted seats.

Those who wanted seats but couldn't get:

= 1,250 * 70%

= 875 people

In 5 years the population will be fewer than 13000.

What is percentage ?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. Percentage, a relative value showing hundredth parts of any amount, is a relative measure that indicates how many questions on a test you correctly answered out of 100 (75/100). Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified percentage.

20000( 1 - 9% )^5

Answer:

0.35cm

Step-by-step explanation:

Step 1

We find the volume of the container.

The formula = Length × Width × Height

Length = 20cm

Width = 30cm

Height = 50cm

The volume of the tank = 20cm × 30cm × 50cm

= 30000 cm³

Step 2

We are told that:

The tank can fill exactly 200 of these containers

We have to find the volume that 1 cylinder will contain

Hence,

200 containers = 30000 cm³

1 container = x

Cross Multiply

200 × x = 30000cm³

x = 30000cm³/200

x = 150cm³

Step 3

We find the base radius of the cylindrical tank

Height = 4m

Convert to cm

1m = 100cm

4m = x

Cross Multiply

x = 4 × 100cm = 400cm

Volume of the cylinder = πr²h

Radius = √V/πh

Radius = √150/π × 400

Radius = 0.35 cm

Therefore, base radius = 0.35cm

The modulus of 2 - 3i is √13. So, the correct option is d.

Modulus is a mathematical operation used to find the remainder when dividing two numbers. This is called a percent sign (%) and is represented by a single number such as 12. Used to determine if two numbers are divisible (no remainder). You can also use the modulus to compare two numbers to see which is greater or lesser. Additionally, this module can be used to calculate the distance between two points on the coordinate plane.

It is computed by taking the square root of the sum of the squares of the real and imaginary components, so √(2^2 + (-3)^2) = √13. The modulus of a complex number, also called absolute value, is a measure of distance from the origin.

Let z = -2 - 3i

z = (-2) + (-3)i

Modulus of z = √((-2)² + (-3)²)

√(4 + 9) = √13

Modulus of z = √13

Answer:

x = 405

Step-by-step explanation:

DBE is 0.1x-33 and the measurement of angle CBE is

The sum of both angles form a right angled triangle ;

DBE + CBE = DBC

DBC = RIGHT angled triangle = 90°

(0.1x-33) + (0.3x - 39) = 90°

0.1x - 33 + 0.3x - 39 = 90°

0.1x + 0.3x - 33 - 39 = 90

0.4x - 72 = 90

To find the difference between (-7*-7) + -(7*7), we first need to calculate the values of each expression.

(-7*-7) = 77 = 49

-(77) = -49

The difference between these two values is 49 - (-49) = 49 + 49 = 98.

Therefore, the answer is A) 98.

The Correct answer is Option (A) = 98.

We need to determine the value of each part and calculate their difference. after that.

Here,    (-7*-7)= 49

and,     -(7*7) = -49

Now, their difference is to be calculated as follows:

          =49 - (-49)

          = 49+ 49

          = 98.

By using the fact that the two images are similar, we can write and solve a linear equation to get x = 3/2.

We know that the two figures are similar, then, if we take the quotient between the adjacent sides for both figures, these quotients should give the same value.

Thus, we can write the equation:

14/10 = (x + 9)/(x + 6)

Now we can solve that equation for x, if we multiply both sides by (x + 6) we will get:

(14/10)*(x + 6) = x + 9

Now we can multiply both sides by 10 to get:

14*(x + 6) = 10*(x + 9)

14x + 84 = 10x + 90

Now we can solve this linear equation for x.

14x - 10x = 90 - 84

4x = 6

x = 6/4

x = 3/2
