The value of x from given quadrilateral ABCD is 27°.

In the given quadrilateral ABCD, ∠A=3x+5, ∠B=2x+15, ∠C=4x and ∠D=4x-10.

We know that, the sum of interior angles of quadrilateral is 360°.

Here, ∠A+∠B+∠C+∠D=360°

3x+5+2x+15+4x+4x-10=360°

13x+10=360°

13x=350°

x=350/13

x=26.9

x≈27°

Therefore, the value of x from given quadrilateral ABCD is 27°.

Water main valves should be located at frequent intervals in a grid system.

The flow and temperature in pipes and plumbing fittings are controlled by water valves. The valves regulate steady flow and volume when they are correctly placed and used. Water valves are made of brass, plastic, stainless steel, bronze, cast iron, and galvanised pipe, among other materials.

The master cutoff valve for the house will typically feature a wheel (a gate valve) or a straight handle (ball valve). The wheel on gate valves (seen on the right) is turned clockwise until the water is shut off. To turn off the water, turn the handle of a ball valve a quarter turn in the opposite direction. Every house has two main water shutoff valves: one inside and one near the intersection of your property and the street.

y = -7

wont let me answer unless I write more

The y-intercept of the equation y = 8x - 7 is -7.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

y = 8x - 7

This is in the form of y = mx + c

So,

c = -7

And,

c = -7 is the y-intercept.

Thus,

The y-intercept of the equation y = 8x - 7 is -7.

The distance between the two slits is 2.51 µm.

According to the problem, two slits are used to pass violet light with a wavelength of  = 415 nm. The first minimum of light will be provided by determining the distance between the two slits at an angle of 48.0°. The angle of minimum is represented by and the distance between the two slits is represented by d. Subbing the given qualities in the situation for the place of the primary least, we get;sin θ = λ/2d

The worth of λ is given to be 415 nm, which can be changed over completely to 4.15 x 10⁻⁷ m. The worth of θ is 48.0°.Converting θ to radians, we get;θ = 48.0° × π/180° = 0.84 rad. When these numbers are added to the equation, we get sin = / 2d0.84 = 4.15 x 107 / 2d. When we rewrite the equation, we get d = / (2 sin) = 4.15 x 107 / (2 sin 0.84)d = 2.51 x 106 m = 2.51 m. As a result, 2.51 m separates the two slits.

Answer:

SA = 486

Step-by-step explanation:

Its a cube. s = side length

V = \(s^{3}\)

729 = \(s^{3}\)

take cube root of each side : \(\sqrt[3]{729}\) = 9

so,  s = 9

Surface Area of a cube

SA = 6\(s^{2}\)

SA = 6(\(9^{2}\))

SA = 6(81)

SA = 486

The surface area of the cube is 486 square inches. The correct option is A.

To find the surface area of a cube, we need to use the formula:

Surface Area = 6 x (side length)²

Given that the volume of the cube is 729 cubic inches, we can determine the side length of the cube using the formula for volume:

Volume = (side length)³

729 = (side length)³

Taking the cube root of both sides:

side length = ∛(729) = 9 inches

Now, we can substitute the side length into the surface area formula:

Surface Area = 6 x (9 inches)² = 6 x 81 = 486 square inches

Therefore, the surface area of the cube is 486 square inches.

False , the variance and standard deviation are not measures of central location

Given data ,

The variance and standard deviation are not measures of central location but measures of dispersion or spread of a dataset

Measures of central location include the mean, median, and mode, which represent the typical or central value of a dataset

The variance and standard deviation are measures of dispersion or spread in a dataset. They provide information about how the values in a dataset are spread out around the mean.

In order to understand the variability or dispersion of data points within a dataset, one must take into account both the variance and standard deviation. They provide information on the range of values and aid in calculating how far away from the mean certain data points are. In statistics and data analysis, these metrics are frequently used to comprehend and evaluate the variance of various datasets.

Step-by-step explanation:

just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.

area = length × width

perimeter = 2×length + 2×width = 136 m

=> length + width = 68 m

then we know

length = 2×width + 8

this we use as substitute in the simplified perimeter equation :

2×width + 8 + width = 68

3×width + 8 = 68

3×width = 60

width = 20 m

and therefore

length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m

and now we can calculate the area :

area = length×width = 48×20 = 960 m²

please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.

Our calculator limits your interest deduction to the interest payment that would be paid on a $1,000,000 mortgage. Interest rate: Annual interest rate for this

Step-by-step explanation:

To calculate the monthly principal + interest payments for a house with a down payment and a mortgage using an Excel formula, you can use the PMT function. Here's how:

Calculate the loan amount by subtracting the down payment from the house cost. In this case, the down payment is 25% of $300,000, so it would be $75,000.
  Loan Amount = $300,000 - $75,000 = $225,000    

Determine the monthly interest rate by dividing the annual interest rate by 12. In this case, the annual interest rate is 2.75%, so the monthly interest rate would be 2.75% / 12 = 0.00229.

Determine the loan term in months. Since it's a 30-year mortgage, the loan term would be 30 * 12 = 360 months.

Use the PMT function in Excel to calculate the monthly principal + interest payment.
  Monthly Payment = -PMT(0.00229, 360, 225000)

The negative sign is used because the payment is an outgoing cash flow.

By using this formula in Excel, you can find the monthly principal + interest payments for your mortgage. Remember to adjust the interest rate, loan amount, and loan term if they differ from the example provided.

To calculate the monthly principal + interest payments using an Excel formula, you can use the PMT function by inputting the appropriate parameters: the monthly interest rate, loan term in months, and loan amount.

The series diverges with an integral of 1/ln(16) and the series converges with an integral of 1/4 and a sum of 1/2.

We can use the integral test to determine the convergence of the series ∑n=1∞ 1/6n. The integral of the function f(x) = 1/6x is:

\(∫f(x) dx = (1/6) ln(x) + C\)

Using the limits of integration from 1 to ∞, we get:

∫1∞ f(x) dx = (1/6) ln(∞) - (1/6) ln(1) = ∞

Since the integral diverges, the series also diverges.

The probability of selecting 25 data values with a mean less than 190 is 0.6%.

What is probability?

What is mean?

Why do you use the word deviation?

Population mean = 20

Standard deviation = 20

Sample size= 25

Sample mean= 190

z = 190-200/20/5

Square root of 25 -10/4 = 2.

Corresponding term is 0.4938 P(X<190) = 0.500-0.4938

P(X<190) = 0.0062 or 0.62

P(X<190) = 0.6%
