Solution :-

As per provided information in the given question, we have been given that the Radius of a cylinder is 4 m. The height of a cylinder is 4 m. We have been asked to find the volume of a right cylinder.

To calculate the volume of a right cylinder, we will apply the formula below :-

[tex] \bigstar \: \: \: \boxed{ \sf{ \: \: Volume_{(Cylinder)} = \pi r^2 h \: \: }}[/tex]

Answer: 20 exhibits

Step-by-step explanation:

    If 11 is 55%, we need to find 100%. We will set up a proportion and solve. Percents are on the bottom, exhibits are on the top.

[tex]\frac{11}{55}[/tex] = [tex]\frac{x}{100}[/tex]

    Cross multiply:

1,100 = 55x

    Divide:

20 = x

    There are 20 exhibits in total.

Answer:

that would be 1/1 or just 1 as your equation of the line.

Step-by-step explanation:

you find this by taking one part of the grid where a line perfectly intersects 2 parts, and you count to the next spot where this happens, in this case would be to the right 1 and up one, making the slope 1/1 which you can simplify into 1. and slope works like y/x, which y is the up and down movement while x is the side to side.

Answer:

y = x + 6

Step-by-step explanation:

two points are;

(0 , 6) & (4 , 10)

The slope: [tex]\frac{10-6}{4-0} =\frac{4}{4} =1[/tex]

The equation:

[tex]y-10=1(x-4)[/tex]

[tex]y-10=x-4[/tex]

[tex]y=x-4+10[/tex]

[tex]y=x+6[/tex]

Hence total cycles:-

Answer is 3

The required there are 3π cycles of the function in a horizontal length of 12π.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

If the period of a function is 4, that means the function completes one cycle every 4 units of horizontal distance.

To find out how many cycles occur in a horizontal length of 12π, we need to divide 12π by the period of the function, which is 4:

Number of cycles = (12π) / 4

Simplifying the expression, we get:

Number of cycles = 3π

So, there are 3π cycles of the function in a horizontal length of 12π.

Answer:

Formula for the area of a circle;

A = π[tex]r^{2}[/tex]

Where 'π' represents pi(22/7 or 3.14), and 'r' stands for the radius being squared.

But, we are given a diameter instead of a radius.

So to find the radius of the diameter we must find 1/2(half) of the diameter:

Diameter/2 = Radius

Plug in what we know:

D/2 = R

8/2 = R

4 = R, 4 is our radius.

Now we use this radius in our formula;

A = π[tex]r^{2}[/tex]

A = 3.14(4^2) ← (The symbol ' ^ ' means to the power of.)

A = 3.14(16)

A = 50.24 centimetres is the area for this circle.

The exchange rate from US dollars to Myanma Kyat is given as:

1 : (45.85 × 1.507) × (0.0928) (Option C).

The rate at which one currency is converted to another is what is referred to as Exchange Rate.

Recall that the following is given from the question:

Step One - Convert from USD to BDT

This gives us 1 : (45.85 × 1.507); Hence, the rate from BDT to MMK is 1 : 0.0928

Step Two: - Ascertain the current rate for USD to MMK

This gives us - 1 : (45.85 × 1.507) × (0.0928). To get a simplified version. One would have to open the brackets.

However, from the above, it is clear that the correct answer is Option C.

Step-by-step explanation:

The required ratio of lollipops to candy bars is 1:2.

Given that,
There are 20 lollipops and 40 candy bars for a gift bag, fill out all of the possible ratios of lollipops to candy bars that could be made is to be determined.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Total number of lollipops = 20, in a bag

Total number of candy bars = 40, in a bag

The ratio of lollipops to a candy bar in a bag,
Ratio = number of lollipops/number of candy bars
Ratio = 20 / 40
Ratio = 1 / 2
Ratio = 1:2

Thus, the required ratio of lollipops to candy bars is 1:2.

Apply Pythagorean theorem

Answer:

25 units

Step-by-step explanation:

Since this triangle is a right triangle, we can use pythogoras theorem to calculate the unknown side length (x). The pythogoras theorem states that the (longest side)² is equivalent to (Side)² + (Side)².

Let the longest side be "c" and the other side lengths be "a and b".

⇒ Pythogoras theorem formula: c² = b² + a²

If this statement is proven false, then the triangle shown is not a right triangle. Now, let's use the formula to determine the missing side length.

Let "c" be "x" and the other side lengths be "7 and 24 (as stated in image)"

SImplify both sides as needed.

Take square root both sides as needed.

The measure of x is 25 units.

Answer:

Step-by-step explanation:

First, you can create a ratio:

Number of people/percentage of total

So 9 being 55% of the painting crew would be:

[tex]\frac{9}{0.55}[/tex], because we are trying to find the total number of painters, you can create another fraction where x is the numerator (number of people) and the denominator is 1 (or 100% of the painters). [tex]\frac{x}{1}[/tex]

Because these fractions are proportions of the same thing, we can set them equal to each other.

[tex]\frac{9}{0.55} =\frac{x}{1}[/tex], cross multiplying gives:

9=0.55x

Dividing both sides by 0.55 gives:

x=(around) 16

Perpendicular projected from center of a circle to its chord bisects it. The value of the x for this case is: x = 1.565 ft approximately.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing in two equal parts) the line segment AB.

Or |AC| = |CB|

For this case, consider the diagram below.

The line OC divides AB in half.

Since it is given that:
Length of AB = |AB| = 2x ft,

therefore, we get:
|AC| + |CB| = 2x

|AC|+|AC| = 2x (as |AC|=|CB|)

therfore, we get: |AC| = x feet = |CB|

Now,as the triangle OBC contains a right angle, we can use Pythagoras theorem, and therefore, we get:

[tex]|OB|^2 = |OC|^2 + |CB|^2\\2.1^2 = 1.4^2 + x^2\\x^2 = 4.41 - 1.96\\x = \sqrt{2.45} \approx 1.565 \: \rm ft[/tex]

(took positive root as 'x' represents measurement of length, which is a non-negative quantity).

Thus, the value of the x for this case is: x = 1.565 ft approximately.

For all [tex]\log_{x_{1}} M[/tex] there is a [tex]\log_{x_{2}}N[/tex] such that [tex]N = M^{\frac{1}{\log_{x_{2}} x_{1}} }[/tex]. The logarithmic expression log ₂ 8 is equivalent to the logarithmic expression log ₃ 27.

Logarithms are trascedental function, that is, a function that cannot be described algebraically.

Let suppose we know that [tex]\log _{x_{1}} M = \log_{x_{2}} N[/tex] such that x₁ ≠ x₂. We proceed to prove that for all [tex]\log_{x_{1}} M[/tex] there is a [tex]\log_{x_{2}} N[/tex] by logarithm properties below:

For example, let suppose that x₁ = 2, M = 8 and x₂ = 3, then the value of N is:

[tex]N = 8^{\frac{1}{\log_{3} 2} }[/tex]

N = 27

Thus, for all [tex]\log_{x_{1}} M[/tex] there is a [tex]\log_{x_{2}}N[/tex] such that [tex]N = M^{\frac{1}{\log_{x_{2}} x_{1}} }[/tex]. The logarithmic expression log ₂ 8 is equivalent to the logarithmic expression log ₃ 27.
