Answer:

No solution

Step-by-step explanation:

Given :

Because we have two variables that can cancel out, we can solve the system using elimination as we can easily add the two equations, cancel out one of the variables and solve for the other.

   8x - 3y = 12

+ -8x + 3y = 5

-----------------------

   0x + 0y = 17

Simplifying this we are left with 0 = 17

Because no variables can be defined there are no solutions to the equation.

The required given relationship between the radius and circumference of the circle is not a proportional relationship.

Given that,
A class measured the radius and circumference of various circular objects.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

here
For the proportional relationship,
the ratio of y / x should be equal but,
18 / 3 ≠ 25/4
Which implies that the relationship is not proportional.

Thus, the required given relationship of the radius and circumference of the circle is not a proportional relationship.

Question:

What is the greatest common factor of 32 and 40?

Find the factors of 32 and 40:

The factors are all the numbers the we can divide 32 or 40 by, and the result will be a whole number. Example:32/1= 32, 32/2= 16, yet 32/3 = 10.6 not a whole number so 3 is not a factor of 32.

Factors of 32: 1, 2, 4, 8, 16, 32

Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

Find the greatest factor that is common for both 32 and 40 ( the GCF):

Factors of 32: 1, 2, 4, 8, 16, 32

Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

GCF is 8

The given equation, -6 1/4x = -3 1/8, solved for is x = 1/2

From the question, we are to solve the given linear equation.

The given linear equation is

-6 1/4x = -3 1/8

To solve the equation,

First, we will convert the fractions to improper fractions

-6 1/4x = -3 1/8

-25/4x = -25/8

Multiply both sides of the equation by -4/25

-4/25 × -25/4x = -4/25 × -25/8

x = 1/2

Hence, the value of x is x = 1/2

Answer: uf

Step-by-step explanation:

It will take 88 hours to fill the order if the number of machines is; deceased by a factor of 4.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Six machines working simultaneously can complete a big order in 22 hours.

Since we are decreasing the number of machines by a factor of four and all the machines work at the same rate, then we simply going to increase the work hours by a factor of 4.

Therefore Increasing the work hours by a factor of 4 will

22 x 4 = 88 hours

Hence it will take 88 hours to fill the order if the number of machines is deceased by a factor of 4.

The final interval notation is  F ∩ H = [7, 4] &  F ∪ H = [-∞, ∞].

What is the interval notation?

A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.

We have,

F and H are sets of real numbers defined as follows.

F = { v l v < 4}

H = { v l v ≥ 7}

F is the set of all real numbers that are less than or equal to 4.  H is the set of real numbers greater than 7.

F U H is the union (or combination) of the two sets, so it is the set of all real numbers that are less than equal to 3 or greater than 6:

F ∩ H is the set of real numbers that are in both sets; but since F is less than or equal to 4 and H is greater than 7, there are no numbers that are in both sets.  Hence the answer is the empty set, Ø:

F ∩ H = Ø

F ∩ H = [7, 4]

F ∪ H = [-∞, ∞]

Hence, the final interval notation is  F ∩ H = [7, 4] &  F ∪ H = [-∞, ∞].

The linear depreciation function is: Depreciation = [tex]\frac{Cost-scrap value}{Estimated life span}[/tex],  (b) the value after five years is $11510 and (c) rate of depreciation is 11%

We should know that depreciation is a loss on a fixed asset over the accounting period that benefited from it.

The given parameters are

Cost of the asset (MSRP)= $25020

Scrap value = $14212

Estimated life span = 4 years

a.   Applying the depreciation model

Deprecation = [tex]\frac{Cost of asset - scrap value}{estimated life span}[/tex]

Depreciation = [tex]\frac{25020-14212}{4}[/tex]

depreciation = 10808/4

Dep. = $2702

(b) Note that the accumulated depreciation after 5 years is 2702*5

=$13510

The value of the car after 5 years is $(25020-13510)

=$11510

(c)  The rate of depreciation is determined by the model

% dep. = 1-[tex]\sqrt[n]{\frac{s}{c} }[/tex]

where n= number of years

s=scrap value

c cost of the asset

Applying the formular we have

% dep - 1-[tex]\sqrt[5]{\frac{14212}{25020} } = 1-\sqrt[5]{0.5680}[/tex]

% dep= 1-0.89

=0.11*100

In conclusion, the linear depreciation function is (Cost - Scrap value)÷Number of years, the value of the car 5 years from now is $11510 and the rate of depreciation is 11%

The smallest positive solution is 13.28⁰.

Trigonometry is a discipline of mathematics dealing with particular angle functions and their application to computations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names.

Given,

sin (2x)cos(6x) - cos(2x)sin(6x) = - 0.8

Let, assume 2x = A and 6X= B

As we know, sin (A-B) = sin A cos B - cos A sin B

Putting the value of 2x and 6x in the given equation, we get

or, sin A cos B - cos A sin B = -0.8

or, sin (A-B) = -0.8

or, sin (2x-6x) = - 0.8

or, sin (-4x) = - 0.8

or, - sin 4x = - 0.8

or, sin 4x = 0.8

Apply sin on both side we get,

or, sin⁻¹ (sin 4x) = sin⁻¹ (0.8)

or, 4x = 53.13

or, x = 13.28⁰

The smallest positive solution is 13.28⁰.

Answer: x=12

Step-by-step explanation:

first you add 4 to both side to make it 2x=24 then you divide both side by 2 to get 12 so x=12.

Answer:

Step-by-step explanation:

Firstly you want to get x alone on one side of the equation. So to do that you move 4 to the other side of the equation. When a number crosses the equal sign, the sign (+/-) switches. Hence 2x - 4 = 20 becomes 2x = 20 +4. Which gives you 2x  = 24.  Now you can solve for x.

2x is really 2 multiplied by x. The opposite of multiplication is division so to get rid of the 2 and get x alone on one side, you divide 24 by 2.

So the equation becomes x = 24/2 (24 divided by 2)

This gives you x = 12.

Associative Property

Step-by-step explanation:

Associative Property is the ability to change the order of an equation, and get the same result.

For example:

(1 + 2) + 3 = 6

If you were to take this equation, and this equation:

3 + 2 + 1 = 6

These numbers are in a different order, but the answer is the same!

It goes the same way for your problem.

57/80 + 21/80 and 21/80 + 57/80.

Therefore, the property to help you would be Associative Property.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability of pulling a green one and then, without replacing it, pulling a blue one is 0.021.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Total number of balls = 20

Red = 5

Blue = 4

Green = 2

Brown = 4

Yellow = 5

The probability of pulling a green one.

= 2/20

= 1/10

Number of balls remaining = 20 - 1 = 19

The probability of pulling a blue without replacing the first green one.

= Number of blue balls / Total number of remaining balls

= 4/19

Now,

The probability of pulling a green one and then, without replacing it, pulling a blue one.

= 1/10 x 4/19

= 4/190

= 2/95

= 0.021

Thus,

The probability of pulling a green one and then, without replacing it, pulling a blue one is 0.021.
