Answer:

11

Step-by-step explanation:

This will form triangle VWX. So we have values for ∠VWX and ∠XVW but we don't have value for ∠WXV.

Since ∠WXV and ∠WXY are supplementary angles

=> ∠WXV + ∠WXY = 180

=> ∠WXV = 180 - ∠WXY

So the angles of triangle VXY

∠VWX + ∠XVW + ∠WXV = 180

(x + 14) + (x + 9) + (180 - (5x - 10)) = 180

x + x - 5x + 14 + 9 + 180 + 10 = 180

-3x + 213 = 180

-3x = - 33

x= 11

Answer:

F (-3) = -8

Step-by-step explanation:

We start by substituting x = -3 into F (x) = 2x - 2

That gets us to: F ( -3) = 2 * (-3) - 2

Then we calculate the equation, bringing us to:

F (-3) = -6 - 2

When we add -6 + -2 we get: F (-3) = -8

If Peyton needs to order some new supplies for the restaurant where she works. The restaurant needs at least 732 forks. the number of sets of forks Peyton could buy for the restaurant to have enough forks is 44.5.

Let x represent the number of sets of forks

Formulate the inequality

287 + 10 × x = 732

Hence,

10x = 732 -287

10x = 445

Divide both side by 10x

x = 445/10

x = 44.5

Therefore we can conclude that 44.5 represent the number of the set of forks that could be bought.

So (Didn't even know what it was until now), is a square where all rows, columns, and diagonals sum up to the same number.

So, from the diagonal of 7, 15, and 23, but adding them up, we can tell that each row, column, and diagonal should sum up to 45.

The amount of Muskco's work force that he has in  his business is; 138 people

We are told that Muskco gave 88 people a bonus. Now, we are further told that if he had given 4 more people bonuses, then it means he would have rewarded two thirds of his workforce.

Thus we can begin too solve this problem to find the size of Muskco's work force by;

Let the total number of his workforce be denoted as x. Then the algebraic equation for this problem would be expressed as;

88 + 4 = (2/3)x

Simplify by adding up the left hand side values to get;

(2/3)x = 92

Use multiplication property of equality to Multiply both sides by 3 to get;

2x = (92 * 3)

2x = 276

Now, use division property of equality to divide both sides by 2 to get;

2x/2 = 276/2

x = 138

Thus, we would conclude from the calculations as seen in the above that the size of Muskco's workforce is 138 people.

Given the figure of an object consists of a cylinder and a rectangular prism.

We will find the volume of the cylinder using the following formula:

As shown, the diameter of the base = d = 3 ft

So, the radius = r = d/2 = 3/2 = 1.5 ft

And the height = h = 4 ft

Use π = 3

so, the volume of the cylinder will be as follows:

Now, we will find the volume of the rectangular prism using the following formula:

As shown, the length = l = 7 ft

The width = w = 4 ft

The height = h = 4 ft

So, the volume of the rectangular prism will be as follows:

So, the total volume of the object will be =

So, the answer will be V = 139 ft³

what is the maximum amount of money she will earn in the craft fair?​

________________________________________

1 lb of candle wax will fill 20 oz

She buys a 5-pound package, therefore, she will fill 20*5= 100 oz

Tin size S small (4 oz ) and M medium (6 oz)

S*4 + M*6 = 100

S*7.5 + M*9 = amount of money

_____________________

S*4 + M*6 = 100

4 S = 100 - 6M

S= 100/4 -6/4M

S= 25 -3/2M

Replacing

(25 -3/2M )*7.5 + M*9 = amount of money

187.5 - 11.25M + 9M = amount of money

187.5 - 2.25M = amount of money

According to the expression, the fewer medians sell, the higher the income will be.

The number of high-quality version downloads is 300.

Given:

Size of the standard version = 2.8 megabytes (MB).

Size of the high-quality version = 4.5 MB.

Total number of downloads = 870

Total download size = 2946 MB

Let the number of high-quality version downloads be x.

Then the number of standard version downloads will be 870 - x.

Now the sum of the number of downloads of each type multiplied by their sizes equals 2946 MB.

So the equation is,

4.5x + 2.8(870 - x) = 2946

4.5x + 2436 - 2.8x = 2946

1.7x = 2946 - 2436

1.7x = 510

x = 510/1.7

x = 300

Therefore, the number of high-quality version downloads is 300.

By using algebra resolution methods for systems of linear equations, we find that the equation of the form f(x) = a · x² + b · x + c that passes through the three points is equal to f(x) = (5 / 2) · x² + (3 / 2) · x.

In this problem we must determine the coefficients of a quadratic equation that passes through the points (x₁, y₁) = (1, 4), (x₂, y₂) = (2, 13) and (x₃, y₃) = (4, 46). First, we need to create a system of linear equations by substituting on y and x thrice:

(x₁, y₁) = (1, 4)

a · 1² + b · 1 + c = 4

a + b + c = 4

(x₂, y₂) = (2, 13)

a · 2² + b · 2 + c = 13

4 · a + 2 · b + c = 13

(x₃, y₃) = (4, 46)

a · 4² + b · 4 + c = 46

16 · a + 4 · b + c = 46

Then, we find a system of three linear equations with three variables that offers an unique solution:

a + b + c = 4                             (1)

4 · a + 2 · b + c = 13                 (2)

16 · a + 4 · b + c = 46               (3)

There are different methods to find the solution to this system, we proceed to use algebraic substitution:

By (1):

c = 4 - a - b

(1) in (2) and (3):

4 · a + 2 · b + (4 - a - b) = 13

3 · a + b = 9                          (2b)

16 · a + 4 · b + (4 - a - b) = 46

15 · a + 3 · b = 42                  (3b)

By (2b):

b = 9 - 3 · a

(2b) in (3b):

15 · a + 3 · (9 - 3 · a) = 42

15 · a + 27 - 9 · a = 42

6 · a = 15

a = 15 / 6

a = 5 / 2

By (2b):

b = 9 - 3 · (5 / 2)

b = 9 - 15 / 2

b = 18 / 2 - 15 / 2

b = 3 / 2

By (1):

c = 4 - 5 / 2 - 3 / 2

c = 4 - 8 / 2

c = 4 - 4

c = 0

The coefficients of the quadratic equation are (a, b, c) = (5 / 2, 3 / 2, 0).

The value of x such that f(x) and g(x) have equal values is 3

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

From the question, we have

f(x) = -2x + 4

g(x) = 2x - 8

The question implies that the functions have equal values

This means that

f(x) = g(x)

Substitute f(x) = -2x + 4 and g(x) = 2x - 8 in f(x) = g(x)

So, we have the following equation

-2x + 4 = 2x - 8

Collect the like terms

2x + 2x = 8 + 4

Evaluate the like terms

4x = 12

Divide both sides of the equation by 4

x = 3

Hence, the value of x such that the equations are equal is 3

6a + -9b = 0

Solving

6a + -9b = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '9b' to each side of the equation.

6a + -9b + 9b = 0 + 9b

Combine like terms: -9b + 9b = 0

6a + 0 = 0 + 9b

6a = 0 + 9b

Remove the zero:

6a = 9b

Divide each side by '6'.

a = 1.5b

2) After 8 years of straight-line depreciation, the car's value will be $19,080.

Depreciation is an accounting term that refers to the periodic expensing of the cost of a long-term asset.

Using depreciation, a reporting entity annually recognizes the cost of an asset used for many years.

Intangible long-term assets use amortization or depletion instead of depreciation to describe the same meaning.

Price of an automobile in 2003 = $30,600

Annual depreciation = $1,440

The car's value after t years = $19,080.

Value after t years = 30,600 - 1,440t

If 19,080 = 30,600 - 1,440t

1,440t = 30,600 - 19,080

1,440t = 11,520

t = 8 (11,520/1,440)

t = 8

= 8 years

Check:

x = 30,600 - 1,440t
