The solution to the system of equations is x = -2 and y = 4

How to solve the equation

To solve this system of equations using Cramer's rule, we need to first express the equations in standard form: Ax + By = C

According to the problem, we have the equations

4x + 3y - 4 = 0

6x = 8 - 5y.

This is the same as

4x + 3y = 4

6x + 5y = 8

The determinants required for Cramer's rule:

Coefficient matrix (D)

[tex]\[D = \begin{vmatrix} 4 & 3 \\ 6 & 5 \end{vmatrix} = (4 \times 5) - (3 \times 6) = 20 - 18 = 2\][/tex]

For Dₓ

[tex]\[D_x = \begin{vmatrix} 4 & 3 \\ 8 & 5 \end{vmatrix} = (4 \times 5) - (3 \times 8) = 20 - 24 = -4\][/tex]

For D y

[tex]\[D_y = \begin{vmatrix} 4 & 4 \\ 6 & 8 \end{vmatrix} = (4 \times 8) - (4 \times 6) = 32 - 24 = 8\][/tex]

Using Cramer's rule:

[tex]\[x = \frac{D_x}{D} = \frac{-4}{2} = -2\][/tex]

[tex]\[y = \frac{D_y}{D} = \frac{8}{2} = 4\][/tex]

Step-by-step explanation:

The wavelength of an electromagnetic wave with a frequency of 135,000 Hz is approximately 2,222 meters. This can be calculated using the equation λ = c / f, with c being the speed of light and f the frequency of the wave.

The wavelength of an electromagnetic wave can be calculated from the frequency when we understand their relationship through the wave's speed. In the case of an electromagnetic wave, this speed is the speed of light (denoted by c), which is approximately 3.00 x 108 m/s. This relationship is expressed by the equation c = fλ, where f is the frequency and λ is the wavelength.

To calculate the wavelength (λ) from the frequency (f), we rearrange the equation to λ = c / f. Substituting 3.00 x 108 m/s for c and 135,000 Hz for f, gives λ = 3.00 x 108 m/s / 135,000 Hz. After performing the calculation, we find the wavelength to be approximately 2,222 meters.

The wavelength of an electromagnetic wave with a frequency of 135,000 Hz is approximately 2,222 meters, based on the relationship provided by the equation c = fλ.

The wavelength of an electromagnetic wave is directly related to its frequency by the equation c = fλ, where 'c' is the speed of light in vacuum, 'f' is the frequency and 'λ' is the wavelength. In this equation, the speed of light 'c' is typically 3.00 × 108 m/s. Therefore, if we want to figure out the wavelength of an electromagnetic wave with a frequency of 135,000 Hz, we can rearrange the equation to solve for the wavelength: λ = c/f. Substituting the given values, we have λ = (3.00 × 108 m/s)/(135,000 s-1), which simplifies to λ = 2,222 m.

Step-by-step explanation:

It costs $ 30240 to stain floor of the entire room

Solution:

Given that,

Sgt. Merritt has bought a house now that his tour of duty is up

He wants to stain the wood floors of the living room, which measure 18 x 14

Therefore,

length = 18 yards

Width = 14 yards

[tex]Area = length \times width\\\\Area = 18 \times 14\\\\Area = 252[/tex]

Thus area of wood floors is 252 square yards

The stain costs $120 per square yard

[tex]Cost = 252 \times 120\\\\Cost = 30240[/tex]

Thus it costs $ 30240 to stain floor of the entire room

To stain Sgt. Merritt's living room floors, which measure 18x14 feet, first calculate the area in square feet, convert to square yards, and then multiply by the cost per square yard. The total cost will be $3,360.

To determine the cost to stain the wood floors in the living room, first we need to calculate the total area in square yards since the stain is sold by square yard. The room measures 18 feet by 14 feet.

Step 1: Calculate Square Footage

Multiply the length and width in feet to get the square footage:

18 feet × 14 feet = 252 square feet

Step 2: Convert Square Feet to Square Yards

There are 9 square feet in 1 square yard. Therefore, we divide the total square footage by 9 to convert to square yards:

252 square feet / 9 square feet per square yard = 28 square yards

Step 3: Calculate the Cost

The cost to stain one square yard is $120. So, we multiply the total square yards by $120 to get the total cost:

28 square yards × $120 per square yard = $3,360

Therefore, the cost to stain the entire living room floor will be $3,360.

Answer:

0.3859

Step-by-step explanation:

Assuming on the average, a jar of peanut butter contains 452 grams, with a standard deviation of 10.4 grams.

Then we have

[tex] \mu = 452 \: and \: \sigma = 10.4[/tex]

We want to find the probability that a jar contains less than 449 grams.

We first determine the z-score of x=449 grams using:

[tex]z = \frac{x - \mu}{ \sigma} [/tex]

We plug in these values to get:

[tex]z = \frac{449 - 452}{10.4} [/tex]

[tex]z = \frac{ - 3}{10.4} = - 0.29[/tex]

Now we read from the standard normal distribution table the area that corresponds to a z-score of -0.29

P(X<449)=0.3859

To find the probability that a jar contains less than 449 grams, calculate the z-score and use a standard normal distribution table or calculator.

To find the probability that a jar contains less than 449 grams, we can use the standard normal distribution and the z-score formula. The z-score is calculated as (X - mean) / standard deviation. In this case, X = 449, mean = 452, and standard deviation = 10.4. By substituting these values into the formula, we can find the z-score, and then use a standard normal distribution table or calculator to find the probability.

1. Calculate the z-score: (449 - 452) / 10.4 = -0.2885

2. Use a standard normal distribution table or calculator to find the probability associated with a z-score of -0.2885. The probability is approximately 0.3830, or 38.30%.

Answer:

39 percent is increase in mileage.

Thus, the correct option is B. 39%.

Step-by-step explanation:

Given:

A runner increased her distance from 9 miles to 12.5 miles a week.

Now, to find percent increase in mileage.

Previous mileage = 9 miles.

Present mileage = 12.5 miles.

Mileage increase = 12.5 - 9 = 3.5 miles.

Now, to get the percent increase in mileage:

[tex]\frac{Mileage\ increased}{previous\ mileage} \times 100[/tex]

[tex]=\frac{3.5}{9} \times 100[/tex]

[tex]=\frac{350}{9}[/tex]

[tex]=38.88\%.[/tex]

Approximately the percent increase = 39%.

Therefore, 39% is increase in mileage.

Thus, the correct option is B. 39%.

3)  x = 15; 95 and 85      4)  x = 12; 98 for both angles

Step-by-step explanation:

2x + 65 + 3x + 40 = 180       Set the equations equal to 180

5x + 105 = 180                      Combine like terms

     - 105  - 105                      Subtract 105 from both sides

5x = 75                                  Divide both sides by 5

x = 15

Plug 15 into both equations

2(15) + 65 = 95

3(15) + 40 = 85

4)  5x + 38 = 9x - 10             Set the equations equal to each other

  - 5x          - 5x                    Subtract 5x from both sides

 38 = 4x - 10

+ 10       + 10                         Add 10 to both sides

48 = 4x                                  Divide both sides by 4

12 = x

Plug 12 into both equations

5(12) + 38 = 98

9(12) - 10 = 98
