There are an infinite number of planes in a 3 dimensional coordinate system.

The 3 dimensional coordinate system is made up of three axes (x, y, and z) that are all perpendicular to each other. These axes create a 3D space that can be used to plot points and objects. In this 3D space, an infinite number of planes can be created. Planes are defined by a mathematical equation that gives the values of the x, y, and z components. These equations can be manipulated to create planes that are parallel, perpendicular, or angled in relation to the coordinate system axes. Additionally, planes can be shifted up, down, left, right, forward, and backward, creating an infinite number of potential planes in a 3D coordinate system.

The degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

What is the measures of the angles in a triangle?

If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry.

A) The sum of the angles in a triangle is 180 degrees. Using this fact, we can write:

m∠d + m∠e + m∠f = (4x-4) + (6x-3) + x = 11x - 7

Since this is the sum of the angles in the triangle, it must equal 180 degrees. Therefore, we can write:

11x - 7 = 180

Solving for x:

11x = 187

x = 17

Therefore, x = 17.

B) Now that we know x, we can find the measure of each angle by substituting it into the expressions given for each angle:

m∠d = 4x - 4 = 4(17) - 4 = 64 degrees

m∠e = 6x - 3 = 6(17) - 3 = 99 degrees

m∠f = x = 17 degrees

Therefore, the degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

Step-by-step explanation:

First, you want to find out how many total marbles there are. We know there are 6 red, 3 blue, and 5 green. So, 6+3+5=14 total marbles. Since there are 3 blue marbles, the probability of selecting a blue marble is 3/14. This is because you are selecting from a bag of 14 total marbles, 3 of which are the color you want.

The restaurant owns the 225 forks if 4% of the fork owned by the restaurant.

Percentage are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.

A dishwasher at a restaurant washes 9 fork.

These fork represent 4% of the fork owned by the restaurant.

Now, Solving the question:

We can get our answer by displaying as an equality

= 9 to 4/100

= x to 100/100

You can multiply 4 by 25 to get 100 so to get the amount of forks, multiply 9 by 25

=9 × 25 = 225

Sun's diameter is 109.16653 times more than Earth's diameter.

Physical quantities such as length, current, mass, volume, temperature, area, intensity, and others are represented by units of measurement. To express the size of physical quantities, we employ a variety of measuring units, including traditional ones, the metric system, and US customary units.

Units of Length are

Kilometers, Nanometre, Millimeters, Centimeters, Meters, and Decimetres

Here we have

Planet Earth has an approximate diameter of 1.2742×10¹⁰ millimeters.

The sun has a diameter of 1.391×10⁶ kilometers.    

Part I:

Given that, for every kilometer, there are 1,000,000 millimeters,

Here 1000000 = 10⁶

Then the diameter of the earth = 1.2742×10¹⁰/10⁶

= 1.2742×10⁴  

Here using the unit kilometer is best to represent the lengths of the sun and earth's diameter because it allows using fewer digits compare to millimeters.  

Part II

Let Earth's diameter is less 'x' times than Sun's diameter  

=> [ 1.2742×10⁴ ] × x = 1.391×10⁶  

=> x = 1.391×10⁶/1.2742×10⁴ = 1.0916653 × 10² = 109.16653  

Therefore,

Sun's diameter is 109.16653 times more than Earth's diameter.

The expression that will help Eshaal determine the length of segment BC is: BC = DE - AB

Since segments DE and AB are parallel, we can use the following expression to calculate the length of segment BC: BC = DE - AB. This expression states that the length of BC is equal to the length of DE minus the length of AB.

If segments DE and AB are parallel, we can use a simple expression to find the length of segment BC. This expression is: BC = DE - AB. This expression states that the length of BC is equal to the difference of the length of DE and the length of AB. In other words, if we know the lengths of segments DE and AB, we can calculate the length of segment BC by subtracting the length of segment AB from the length of segment DE. This expression is a useful tool for finding the length of segment BC when we know the lengths of segments DE and AB.
