The equation that can be used to determine the total cost, given the number of movie tickets, is c = 8. 50 c

The equation that shows the total cost when you buy a certain number of tickets, can only be found after you solve for the ticket price.

The ticket price is :
= Cost of tickets / Number of tickets

= 42. 50 / 8

= $ 8. 50

The equation for the total cost would therefore be:

Total cost = Number of tickets x Cost per ticket

c = f x 8. 50

c = 8. 50 f

Answer:

Solving by Factoring is a strategy used to solve quadratic equations. This strategy involves factoring the quadratic equation. Factoring is breaking an expression down into smaller expressions that when multiplied together will equal the original expression.

Step-by-step explanation:

To solve a quadratic equation by factoring we must first get the equation into the form ax^2 + bx + c = 0. From here we must use a strategy of factoring known as Reverse FOIL. By using reverse FOIL we will break the equation down into smaller parts. The four steps to use in reverse FOIL are:

1. Find two factors of “ac” (the coefficient of x^2) that when added together equal “b” (the coefficient of x).

2. Multiply the two factors you found in step one to produce “ac.”

3. Group the two terms with the “ac” terms in the equation.

4. Factor the two terms with “bx” in them.

For example, if we have an equation such as 9x^2 + 15x + 4 = 0  we would look for two factors of 4 (ac) that when added together equal 15 (b). The two factors of 4 that when added together equal 15 are -1 and -4. Therefore our equation would become: (9x^2 -1x -4x +4) and we can group the terms like this: (9x^2 -1x)(-4x +4).

The fourth step is to factor the two terms with “bx” in them. In our equation, the two terms with “bx” in them are -1x and -4x. Factoring these terms give us: (9x^2 -1x)(-4x +4) = (3x -1)(3x -4).

The final step is to find the two solutions, or the “x” values, that make the equation equal zero. To find these two x values, just set each factor to zero, and solve the resulting equations. In this example, setting the first factor, (3x - 1) equal to zero, we get x = (1/3); setting the second factor, (3x - 4) equal to zero, we get x = (4/3).

Therefore, the two solutions to 9x^2 + 15x + 4 = 0 are x = (1/3) and x = (4/3).

Using the strategy of Factoring, we have been able to successfully solve the equation 9x^2 + 15x + 4 = 0.

Answer: Elijah's debt-to-credit ratio is 37%.

Step-by-step explanation:

Elijah's debt-to-credit ratio is the ratio of the amount of money he owes to the total amount of credit he has available.

To calculate the debt-to-credit ratio, we need to divide the amount of debt by the total amount of credit, and then multiply by 100 to get the answer in percentage.

Debt = $2,127.50

Credit = $5,750.00

Debt-to-credit ratio = (Debt / Credit) * 100

Debt-to-credit ratio = (2127.50 / 5750) * 100 = 37.29 ~ 37%

So the answer is: b) 37%

Answer:

Let x be the number of guppies Percious can purchase.

We know that the total cost of the goldfish, starfish and guppies is less than or equal to $80.

We can use this information to write an inequality:

32 + 12 + 6x <= 80

This inequality represents the total cost of the goldfish, starfish, and guppies.

By solving this inequality we can find the number of guppies Percious can purchase.

To solve this inequality, we can first simplify it by combining like terms:

44 + 6x <= 80

Then we can subtract 44 from both sides:

6x <= 36

And finally, we divide both sides by 6:

x <= 6

So, Percious can purchase a maximum of 6 guppies if she wants to spend all of her money.

x is less than or equal to 6.

The total interest paid for the period of three months will be $600 on the loan amount of $550000.

The interest is the charges levied on the amount which we borrow from any bank for a particular period of time.

Here in the question given data is

P= $550000

R=2.0%+2.8%=4.8%

T=1/4 years or three months

So from the simple interest formula

SI = PRT / 100

= 550000 x 4.8 x 1/4 / 100

= 6600

Hence, the total interest paid for the period of three months will be $600 on the loan amount of $550000.

[tex]\frac{1}{4}[/tex] d = [tex]\frac{1}{5}[/tex]d = 1

[tex]\frac{5}{20}[/tex] d + [tex]\frac{4}{20}[/tex] d = 1

[tex]\frac{9}{20}[/tex] d = 1  Multiply both sides by [tex]\frac{20}{9}[/tex]

d = [tex]\frac{20}{9}[/tex]   I can break 20 into 9 + 9 + 2

d = [tex]\frac{9}{9}[/tex] + [tex]\frac{9}{9}[/tex] + [tex]\frac{2}{9}[/tex]           [tex]\frac{9}{9}[/tex] = 1

Step-by-step explanation:

The simultaneous equation 5x + 2y = 9 and x + y = -3 is solved by elimination method as follows

There are various methods of solving simultaneous equation however for this problem we solve with elimination method

The equation is 5x + 2y = 9 and x + y = -3

multiply x + y = -3 by 2

2x + 2y = -6

subtract 2x + 2y = - 6 from 5x + 2y = 9

5x + 2y = 9

2x + 2y = - 6

this will result to 3x = -15

solve for x by dividing by 3

x = -5

substitute x = -5 to x + y = -3

-5 + y = -3

y = -3 + 5

y = 2

hence x = -5 and y = 2

The cost of both the shirt and pants each is $10, solved using elimination method.

Let s stand for shirt and p for trousers.

Then we may solve the following equations:

1st Equation:

2s + 3p = 50

2nd Equation:

3s +1p = 40

Our initial aim is to determine the cost of one shirt. To get rid of the pants, we might artificially multiply the second equation by -3. This is what it would look like:

2s + 3p = 50

-3(3s +1p) = -3(40) (40)

———————————————

2s + 3p = 50

-9s - 3p = -120 We can obviously remove the pants (p) now.

—————————————

-7s = -70

Divide both sides by -7 to isolate s, and we get:

s = 10 -> As a result, one shirt costs $10.

Pants = 2(10) + 3p = 50

p = $10

Let us calculate the cost of 5 shirts.

As a result, we will perform 5 x $10 = $50.

0.9976 percent of the time, the automobile won't start immediately away.

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range, while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the center of the range.

Given that,

X = number of morning car starts right away

X          0            1            2             3               4              5

p(x)  0.0024   0.0283   0.1323   0.3087    0.3601    0.1681

So now we are able to find the given probability

p(x ≥ 1) = 1 - p(0)

1 - 0.024 = 0.9976

Answer:

The answer is 32

Step-by-step explanation:

We solve this by first finding the angle 3. To do this we subtract 180 (the sum of a triangle) and the two known angles. 180-15-17 = 148.

So now we know that the 3rd angle is equal to 148. Now to find the angle 4 we subtract angle 3 from 180, because a straight line is equal to to 180 degrees; 180-148=32

Hope that helps

The tangent of the subtraction of angles x and y is defined as follows:

tan(x - y) = (36 - 20π)/(48 + 15π)

The tangent of the subtraction of two angles is obtained according to the identity presented as follows:

tan(x - y) = [tan(x) - tan(y)]/[1 + tan(x)tan(y)]

The tangent of angle x is given as follows:

3/4.

The tangent and cotangent are defined as follows:

Hence the tangent of angle y is obtained inverting the numerator and the denominator of the function, as follows:

tan(y) = 5π/12.

The subtraction of the two tangents is given as follows:

tan(x) - tan(y) = 3/4 - 5π/12 = 9/12 - 5π/12 = (9 - 5π)/12.

The quotient of the two tangents is given as follows:

tan(x)tan(y) = 3/4 x 5π/12 = 15π/48.

Then the denominator of the expression is given as follows:

1 + 15π/48 = (48 + 15π)/48.

Considering the division of the two fractions, the tangent of the subtraction is defined as follows:

tan(x - y) = (9 - 5π)/12 x 48/(48 + 15π)

tan(x - y) = (36 - 20π)/(48 + 15π)

midsegment = [tex]\frac{WT+VU}{2}[/tex] = [tex]\frac{17.5+6.1}{2}[/tex] = [tex]\frac{23.6}{2}[/tex] = 11.8

Since Z and 92 both have vertical angles, they are equal. Subtract from 180 to determine the measure of the other angle, which is 88 degrees since it forms a straight line with the 92-degree angle. Solve the expression by setting the value at 88.

∠AOB + ∠BOC = 180°

92°+( 10x  +  32 )° = 180°

10x + 32° = 180 - 92

10x + 32° = 88

10x = 88 - 32

10x = 56

x = 56 ÷ 10
