The metric system is defined as the decimal system of units based on the meters, kilograms, and second as the units of length, mass, and time respectively. The imperial system is defined as the measurement system used in countries like the UK, Liberia, Myanmar, etc. that uses units like an inch, pound, ton etc.

The Metric and Imperial systems are both systems of measurement. That is, they are not just one unit of measure, but are correlated systems of many units of measure – measuring length and area, weight and mass, volume, force, temperature etc.

The imperial system of measurement is defined as a system that originated in Britain and came to formal use in the early 19th century with the Weights and Measures Act of 1824 and 1878. It uses some of the commonly used units there like an inch, ton, pound, gallon, pint, etc.

Most countries use the metric system which uses the measuring units such as meters and grams, and adds prefixes like kilo, milli, and centi to count orders of magnitude.

the value of x will be 8√2 for the given right-angle triangle.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, Two right-angle triangles one with the height of "x" and a base angle of 45-degree.

Another with a base of 8 and a base angle of 60-degree.

From the cosine rule of trigonometry:

Cos θ = base/(hypotenuse)

Sin θ = height/(hypotenuse)

For the triangle with a base angle of 45-degree

sin 45 = height/(hypotenuse)

1/√2 = x/(hypotenuse)

hypotenuse = x *√2.....(1)

For the triangle with a base angle of 60-degree

cos 60 = base/(hypotenuse)

1/2 = 8/(hypotenuse)

hypotenuse = 16

substitute this value in equation 1

x = 8√2

Answer:

  65 cm

Step-by-step explanation:

You want the perimeter of the shape that results from removing a 60° sector from a circle.

The curved edge of the shape is 5/6 of the circumference of the circle.

  5/6C = 5/6(2πr) = 5/6·2·π·(9 cm) = 15π cm ≈ 47 cm

Each straight edge of the shape has a length equal to the radius. Then the straight edges have a total length of ...

  2r = 2(9 cm) = 18 cm

The perimeter of the shape is the sum of the length of its curved edge and the lengths of the straight edges:

  P = 47 cm + 18 cm = 65 cm

The perimeter is about 65 cm.

Additional comment

A total circle is 360°, so 1/6 of the circle is 60°. The size of a sector of a circle can be described by the angle measure of its central angle. Here, that means the removed portion is a 60° sector.

Answer:

(4 × y) - 8 = <26

Step-by-step explanation:

The equation for this problem is:

(Let y = the unknown number)

Therefore, you can use (4 × y) - 8 = <26 as an inequality for this problem.

The two lines that are parallel to y = 2x - 1 that pass through the given points are:

a) y = 2x + 1

b) y = 2x

A general linear equation is written in the slope-intercept form as:

y = a*x +b

Where a is the slope and b is the y-intercept.

Two lines are parallel if the slopes are equal but the y-intercepts are different.

So, here we want to find lines parallel to:

y = 2x - 1

These lines have the form:

y = 2x + b

a) If we want our line to pass thrugh A(0,1), we can replace the values of the point to get:

1 = 2*0 + b

1  = b

So the line is y = 2x + 1

b) if we want the line to pass through A(1,2) we can replace the values to get:

2 = 2*1 + b

2 = 2 + b

2 - 2 = b

0  =b

So this line is:

y = 2x

A pile of 6 boards is 2 timed the volume of a pile of 3 boards with the given dimensions. Option D is the correct answer.

The dimension of an item in mathematics is, approximately speaking, the quantity of degrees of freedom of a moving point on the object. To put it another way, a dimension is indeed the amount of distinct factors or coordinates required to define the location of a point that must be on an object. For instance, a point has a dimension of zero; a line has a size of one since a point can only move along a line in one direction (or its opposite); a plane has a dimension of two; etc.

The volume of the wooden board is given by the formula:

V = (l)(b)(h)

V = (2)(6)(14)

V = 168 cubic inches.

The volume of pile of 3 boards has dimensions:

l = 14

b = 6

h = 3(2)

V = 3(168) = 504 cubic inches.

Similarly, piling the boards and changing the height.

The volume of pile of four boards = 4(168).

The volume of pile of 5 boards = 5(168)

The volume of pile of 6 boards = 6(168) = 2(3(168))  = 2(Volume of pile of 3 boards)

Hence, a pile of 6 boards is 2 timed the volume of a pile of 3 boards with the given dimensions.

Answer: Let's use algebra to solve this problem.

Let C be Clot's present age and S be Soup's present age. Then, according to the problem:

One year ago, Clot was C-1 years old, and four times Soup's age at that time was 4(S-1).

Clot's age one year ago was one-third of four times Soup's age, so we have:

C - 1 = (1/3) * 4(S - 1)

Simplifying this equation, we get:

C - 1 = (4/3)(S - 1)

C = (4/3)(S - 1) + 1

One year from now, Clot will be C + 1 years old, and Soup will be S + 1 years old. The sum of their ages will be 21, so we have:

(C + 1) + (S + 1) = 21

C + S + 2 = 21

C + S = 19

Now we have two equations with two unknowns. We can substitute the expression for C from the first equation into the second equation to get an equation in terms of S:

(4/3)(S - 1) + 1 + S = 19

Simplifying and solving for S, we get:

S = 6

Substituting S = 6 into the equation C + S = 19, we get:

C + 6 = 19

C = 13

Therefore, Clot's present age is 13 and Soup's present age is 6.

Therefore, we would anticipate finding 150,000x golden fish throughout the entire lake based on the class average.

Volume is the measure of room within a particular 3D entity in mathematics. For illustration, a fish aquarium measures three feet long by one foot wide by two feet high. The capacity is calculated by multiplying the length, the breadth, and the height, or 3x1x2, that also equals six. The fish aquarium therefore has a 6 cubic foot capacity.

Let's say the class average is "x" yellow fish per liter of water.

If the sample contained 500 liters of water, we can estimate the number of yellow fish in the sample as:

Answer: 20

Step-by-step explanation: The volume formula for a rectangular pyramid is [tex]\frac{lwh}{3}[/tex] so the initial volume would be 540. Since you are dilating it by 1/3 the length, with, and height are all shrinking by 1/3. 1/3*1/3*1/3 is 1/27 so that means the final thing will be 1/27 of its original size.

Answer:

So, first let's understand what a scale factor is. A scale factor is a number that tells you how much you need to multiply the size of an object to make it bigger or smaller. In this case, the scale factor is 1/3, which means we're going to make the pyramid one third of its original size.

Now, let's talk about how we can find the volume of the pyramid. The formula for the volume of a pyramid is:

Volume = (1/3) x base area x height

The base area is the area of the rectangle at the bottom of the pyramid, which we can find by multiplying the length and width:

Base area = 9 cm x 12 cm = 108 square cm

The height of the pyramid is given as 15 cm, so we can substitute these values into the formula:

Volume = (1/3) x 108 square cm x 15 cm

Volume = 540 cubic cm

So the volume of the original pyramid is 540 cubic cm. But we need to find the volume of the pyramid after it is dilated by a scale factor of 1/3. To do this, we need to multiply the original volume by the scale factor cubed. The reason we cube the scale factor is because we're scaling in three dimensions (length, width, and height).

Scale factor cubed = (1/3) x (1/3) x (1/3) = 1/27

Volume of dilated pyramid = 540 cubic cm x 1/27

Volume of dilated pyramid = 20 cubic cm (rounded to the nearest whole number)

So the volume of the pyramid after it is dilated by a scale factor of 1/3 is 20 cubic cm.

Here is an explanation to understand step by step how to do this.

A volume can be determined for any three-dimensional object using formulas that are unique to that item's shape. For instance, the volume of a water bottle indicates how much water it can hold. Understanding an object's volume is crucial since it indicates how much stuff that shape can carry.

Any form or object's volume is directly inversely proportional to the volume of water it displaces when submerged in water because of its link to density. As a result, there are two ways to determine an object's volume: by mathematically calculating it using the formula unique to that shape, or by submerging it in water and measuring the volumetric displacement of the water.

The spherical tanks of Eindhoven can hold a maximum of approximately 14,137 cubic meters of water.

The maximum amount of water that one of the spherical tanks of Eindhoven will hold can be found using the formula for the volume of a sphere:

V = (4/3) * π * [tex]r^3[/tex]

where V is the volume of the sphere, r is the radius of the sphere, and π is a constant equal to approximately 3.14159.

According to the Eindhoven website, the diameter of each spherical tank is 30 meters. The radius, therefore, is half of the diameter, which is:

r = 30/2 = 15 meters

Substituting this value into the formula for the volume of a sphere, we get:

V = (4/3) * π * [tex](15)^3[/tex]

V ≈ 14,137 cubic meters

When we round this to the closest integer, we obtain:

Maximum amount of water = 14,137 cubic meters

Therefore, one of the spherical tanks of Eindhoven can hold a maximum of approximately 14,137 cubic meters of water.
