Answer:

The coefficient of x is 22.

Answer:

Smaller angle = 53.2

Larger angle = 126.8

Step-by-step explanation:

Lets say x is the measure of the supplement. Since we know they're supplementary, we know their angle measure sum will equal 180. We can set up our equation like this \(x + (x-73.6) = 180\). Note: (x - 73.6) is the measure of the smaller angle. By solving, we get 126.8 degrees for the measure of the supplement. If we plug in the value of x into (x-73.6), we get 53.2 degrees as the angle measure of the smaller angle.

To get 4 pairs of blue socks, on average, you would need to choose 16 pairs of socks at random.

The number of socks chosen at random will be denoted by the letter "n." Given by: The anticipated number of blue socks in "n" pairs

Expected number of blue socks = n * 1/4

In order for there to be four blue socks as expected, we need to determine the value of "n." Thus, we can construct the equation:

n * 1/4 = 4

And solving for n:

n = 4 / (1/4) = 4 * 4 = 16

So, To get 4 pairs of blue socks, on average, you would need to choose 16 pairs of socks at random.

Answer:

2√17

Step-by-step explanation:

Start with thinking of factors of 68. Those are:
1, 2, 4, 17, 34, 68

Within this set of numbers, are there any available that are the square of a number? The 4 does! 68 / 4 = 17

So we can change √68 to be √(4 x 17)
Which is the same as √4 x √17
Which can be simplified to 2 x √17
Or 2√17

The value of z in the solution set is approximately -8.33 for the determinant of the matrix of coefficients is −3, Option E is the correct answer.

To solve the system of equations, we can use the method of determinants. The value of z can be determined by finding the determinant of the matrix of coefficients.

The given system of equations can be represented as:

| 1 3 1 | | x | | -2 |

| 2 5 1 | × | y | = | -5 |

| 1 2 3 | | z | | 0 |

The determinant of the matrix of coefficients is -3, which is non-zero. This means that the system of equations has a unique solution.

To find the value of z, we need to calculate the determinant of the matrix obtained by replacing the z-column with the constants column:

| 1 3 -2 |

| 2 5 -5 |

| 1 2 0 |

Using the rule of determinants for a 3x3 matrix, we can calculate the determinant:

Det = (1 × (50 - -52)) - (3 × (20 - -51)) + (-2 × (2 × -5 - 51))

= (1(0 + 10)) - (3 × (0 + 5)) + (-2 × (-10 - 5))

= (110) - (35) + (-2 × -15)

= 10 - 15 + 30

= 25

Since the determinant is non-zero, the system has a unique solution. To find the value of z, we divide the determinant of the matrix obtained by replacing the z-column with the constants column by the determinant of the matrix of coefficients:

z = Detz / Det

= 25 / -3

= -8.33

Therefore, the value of z in the solution set is approximately -8.33.

The factors that affect band gap are material, temperature, pressure and strain.

Band gap refers to the energy difference between the highest occupied energy level and the lowest unoccupied energy level in a material. This energy difference plays a crucial role in determining the electrical and optical properties of a material. The band gap is a critical factor in the design of electronic devices and solar cells.

There are several factors that can affect the band gap of a material. The most important factor is the composition of the material. The band gap is dependent on the electronic structure of the atoms in the material. Another factor that can affect the band gap is the crystal structure of the material. The band gap is influenced by the arrangement of atoms in the crystal lattice.

Temperature is also a significant factor that affects the band gap of a material. As the temperature increases, the energy of the electrons in the material increases, causing the band gap to decrease.

Additionally, external factors such as pressure and strain can also affect the band gap of a material. When a material is subjected to high pressure or strain, its crystal structure can change, altering its electronic properties and causing a change in the band gap.

D-Reflection across x-axis

Answer:  t = 10m

Step-by-step explanation:

We know the lengths of the two legs, but not the length of the hypotenuse.  To calculate this, we use the Pythagorean Theorem: a^2 + b^2 = c^2.

So (6)^2 + (8)^2 = (t)^2

36 + 64 = t^2

100 = t^2

sqrt (100) = sqrt (t^2)

t = 10

Answer:

The pizza parlors cost the same when delivering 4 pizzas.

Step-by-step explanation:

For each store, the total price is

cost of pizzas + cost of delivery

The cost of delivery is just a fixed number for each store, $20 or $12.

The cost of the pizzas is the price of a pizza multiplied by the number of pizzas.

Let x = number of pizzas

The cost of the pizzas is

Jacob's: 10x

Ashley's: 12x

Jacob's total cost (pizzas + delivery):

10x + 20

Ashley's total cost (pizzas + delivery):

12x + 12

We want the total costs to be the same, so we set our two total cost expressions equal and solve for x.

12x + 12 = 10x + 20

Subtract 10 from both sides.

2x + 12 = 20

Subtract 12 from both sides.

2x = 8

Divide both sides by 2.

x = 4

The tank currently contains 44 gallons of water, and 36 more gallons are needed to fill it completely.

a. The fish tank that holds 80 gallons of water is 55% full, which means it contains:

44 gallons = 80 gallons × 0.55

b. To find out how many more gallons are needed to fill the tank, we can subtract the current amount of water in the tank from its full capacity:

80 gallons - 44 gallons = 36 gallons

Therefore, the tank currently contains 44 gallons of water, and 36 more gallons are needed to fill it completely.

Answer:

36 feet

Step-by-step explanation:

Let us first find the area of the of the flower bed. It is a rectangle, so:

A = 18 * 4.5 = 81 square feet

The square flower bed has the same area, therefore, the length of the sides of the flower bed can be gotten. The area of a square is:

\(A = L^2\)

\(81 = L^2\\\\L = \sqrt{81}\)

L = 9 feet

Next, we need to find the perimeter of the square flower bed:

P = 4L

=> P = 4 * 9 = 36 feet

He needed 36 feet of fence to enclose the entire square flower bed.

The probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

To find the probability that the average number of hours of overtime worked by a random sample of 140 employees exceeds 20 hours, we can use the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 18.9 hours and the population standard deviation is 7.8 hours, we can calculate the standard error of the mean using the formula: standard error = population standard deviation / sqrt(sample size).

For this problem, the sample size is 140, so the standard error is 7.8 / sqrt(140) ≈ 0.659.

To calculate the probability, we need to standardize the sample mean using the z-score formula: z = (sample mean - population mean) / standard error.

In this case, the sample mean is 20 hours, the population mean is 18.9 hours, and the standard error is 0.659. Plugging these values into the formula, we get z = (20 - 18.9) / 0.659 ≈ 1.71.

Now, we can use a standard normal distribution table or calculator to find the probability associated with a z-score of 1.71. Looking up this value in the table, we find that the probability is approximately 0.9564.

Therefore, the probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

8 calories per minute on a treadmill and 10 calories per minute on an

elliptical.

Our goal is to burn 560 calories in a 60-minute workout.

let the time spend on treadmill be x and time spend on Elliptical be y.

So, the system of Equation is

x+ y= 60..........(1)

8x+ 10y = 560...............(2)

Solving equation (1) and (2) we get

8(60- y) + 10y= 560

480 - 8y + 10y = 560

2y = 560-480

2y = 80

y= 40

and, x= 60- 40 = 20

So, On treadmill we spend 20 minutes and on Elliptical we spend 40 minutes.
