To solve: First subtract 172 from 400, resulting in 228, then you may subtract the 0.98, leaving 227.02.

Answer:

There are no restrictions on the range of H(w).

The restrictions that are there on the range of the function H(w) is:

Option B: H(w) > 0

The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant.

As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.

Then, the function is defined only for positive values of w and H(w) is always positive.

Then, the answer is H(w) > 0, this is the option B

Answer: 127 degrees

Step-by-step explanation:

I hope this helps

E                       F

H                     G

I had to write it out the parallelogram so I could have a better visual.

F and G are consecutive angles in a parallelogram (not on opposite sides).

This means they add to be 180 degrees.

F+G=180

(3x-10)+(5x+22)=180

(3x+5x)+(-10+22)=180

8x       +12=180

Subtract 12 on both sides:

8x           =180-12

Simplify:

8x           =168

Divide both sides by 8:

x              =168/8

x              =21

If x=21 and want the measurement of angle G, then

(5x+22)=(5*21+22)=127.

So angle G has measurement 127 degrees.

The the measure of angle G will be 127°. Then the correct option is D.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

In parallelogram, the sum of the two adjacent angle is 180 degrees.

In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°.

The angle F and angle G are the adjacent angle.

The sum of angle F and angle G is 180°.

             ∠F + ∠G = 180°

3x - 10 + 5x + 22 = 180

                      8x = 168

                        x = 21

Then the the measure of angle G will be

∠G = (5x + 22)°

∠G = (5 × 21 + 22)°

∠G = (105 + 22)°

∠G = 127°

The the measure of angle G will be 127°.

Then the correct option is D.

a) If a is congruent to b modulo n and m divides n, then a is congruent to b modulo m.

b) If a is congruent to b modulo n and c is a positive integer, then ca is congruent to cb modulo cn.

a) To prove the first statement, assume that a ≡ b (mod n) and m divides n. This means that n = km for some integer k. We want to show that a ≡ b (mod m). Since a ≡ b (mod n), it implies that a - b is divisible by n. Since m divides n, we can express n as n = pm for some integer p. Therefore, a - b = nq for some integer q. By substituting n = pm, we have a - b = pmq. Since pq is an integer, we can conclude that a - b is divisible by m, which means a ≡ b (mod m).

b) To prove the second statement, assume that a ≡ b (mod n) and c is a positive integer. We want to show that ca ≡ cb (mod cn). Since a ≡ b (mod n), it implies that a - b is divisible by n. We can express a - b as (a - b) = kn for some integer k. Multiplying both sides of the equation by c, we get c(a - b) = c(kn), which simplifies to ca - cb = cnk. Since nk is an integer, we can conclude that ca - cb is divisible by cn, which means ca ≡ cb (mod cn).

By using percentage, it can be calculated that

Percentage decrease in the screen time for Lora  = 40 %

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. The fraction is called percentage.

For example 9% means \(\frac{9}{100}\). Here 9 is expressed as a fraction of 100

Here, Percentage decrease will be calculated

Screen time for Lora last week = 840 minutes

Screen time for Lora this week = 504 minutes

Decrease in screen time for Lora = (840 - 504) minutes

                                                        = 336 minutes

Percentage decrease in the screen time for Lora = \(\frac{336}{840}\times 100\) = 40 %

Thus, 25.13 cubic inches is the closest estimate for the ice cream's overall volume.

Volume is a mathematical concept that describes how much space a three-dimensional object occupies. It is frequently expressed in terms of cubic units like cubic metres (m3), cubic feet (ft3), or cubic centimetres (cm3). Depending on the shape of the object, different formulas can be used to determine its volume. Consider this: The formula V = l w h, where l has been the length, w is the broad, and h corresponds to the height of the rectangular prism (box), gives the volume of the object. A sphere's volume can be calculated using the method V = (4/3)r3, where r is the sphere's radius.

given

The formula for a cone's volume is as follows, assuming that the ice cream has the correct circular cone shape with radius r = 2 in and height h = 6 in:

\(V = (1/3) * \pi * r^2 * h\)

Inputting the values provided yields:

\(V = (1/3) * \pi * (2 in) * (2 in) * (6 in)\) = 25.13 cubic inches

Since the car depreciated by 25%, the car was worth £9,000 after the first year.

Calculated is an adjective that describes a process or action that requires the use of mathematics or numerical data. It can refer to anything from complex financial calculations to measuring the area of a room. Calculated is often used to describe decisions or actions that are made after carefully considering the available information. For example, a calculated risk is one that has been assessed for its potential risks and rewards before being taken. Calculated decisions are based on logical reasoning and facts rather than impulse or emotion.


The non-calculator method to find out how much the car was worth after the first year would involve using the concept of percent change. To calculate the percent change, first identify the original amount (the cost of the car before depreciation) and the new amount (the cost after depreciation). In this case, the original amount is £12,000 and the new amount is 25% lower than the original amount.

To find the new amount, first convert the 25% decrease into a decimal. To do this, divide the percentage by 100. 25% can be written as 25/100, which when simplified is 0.25. Subtract the decimal from 1. The difference between 1 and 0.25 is 0.75. This number is the percentage change.

To apply this percentage change to the original amount of £12,000, multiply 0.75 by 12,000. The result of this calculation is £9,000, which is the cost of the car after the first year. Since the car depreciated by 25%, the car was worth £9,000 after the first year.

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx      —-- 1

Now, find k for given x = 3 / 4 and y = 5 / 3, we need to put these values in equation 1, i.e.

5 / 3 = k(3 / 4)

k = (5 × 4) / 9

k = 20 / 9

Further calculate x for given y = ½ and constant of proportion = 20/9i.e.

½ = (20 / 9)x

x = 9 / 40

Hence, the required value of x is 9 / 40.

A positive standard score indicates that the original score is greater than the mean

Step-by-step explanation:

please mark as brainliest

A negative standard score indicates that the original score is lower than the mean.

A standard score, also known as a z-score, is a statistical measure that represents the number of standard deviations an individual score is away from the mean of a distribution. It provides a standardized way to compare and interpret individual scores within a dataset.

When the standard score is negative, it means that the original score is below the mean of the distribution. In other words, the value associated with the score is lower than the average value in the dataset.

For example, if we have a dataset with a mean of 50 and an individual score of 45, we can calculate the standard score (z-score) using the formula:

z = (x - μ) / σ

The correct equation for wave speed depends on the type of wave. For transverse waves, the equation is wave speed = frequency x wavelength, while for longitudinal waves, the equation is wave speed = (1/period) x wavelength.

The equation for wave speed depends on the nature of the wave. In the case of transverse waves, such as electromagnetic waves or waves on a string, the correct equation is wave speed = frequency x wavelength. Frequency refers to the number of complete oscillations or cycles of the wave per unit of time, typically measured in hertz (Hz). Wavelength represents the distance between two consecutive points in the wave that are in phase, such as the crest or trough of the wave. The product of frequency and wavelength gives the speed at which the wave propagates through the medium.

However, for longitudinal waves, such as sound waves, the correct equation is wave speed = (1/period) x wavelength. Period refers to the time it takes for one complete oscillation or cycle of the wave, and it is the reciprocal of frequency. The wave speed in longitudinal waves can be calculated by multiplying the wavelength by the inverse of the period.

Therefore, the correct equation for wave speed depends on whether the wave is transverse or longitudinal. For transverse waves, it is wave speed = frequency x wavelength, while for longitudinal waves, it is wave speed = (1/period) x wavelength.

The inverse of an invertible symmetric matrix A, denoted as A^(-1), is also a symmetric matrix.

The inverse of an invertible symmetric matrix A, denoted as A^(-1), is also a symmetric matrix.

To prove this, let's start with the given information: A is an nxn invertible symmetric matrix, meaning A^T = A. We want to show that A^(-1) is also symetric, i.e., (A^(-1))^T = A^(-1).

Since A is an invertible matrix, it has a unique inverse A^(-1). We can use the properties of transpose and matrix inversion to demonstrate that (A^(-1))^T = A^(-1).

Taking the transpose of both sides of the equation A^T = A, we have (A^(-1))^T * A^T = (A^(-1))^T * A.

Now, multiply both sides by A^(-1) on the left: (A^(-1))^T * A^T * A^(-1) = (A^(-1))^T * A * A^(-1).

By the properties of matrix transpose, (AB)^T = B^T * A^T, we can rewrite the equation as (A^(-1) * A)^T * A^(-1) = A^(-1)^T * A * A^(-1).

Since A^(-1) * A is the identity matrix I, we have I^T * A^(-1) = A^(-1)^T * A * A^(-1).

Since I is symmetric (the identity matrix is always symmetric), we can simplify the equation to A^(-1) = A^(-1)^T * A * A^(-1).

Now, we have shown that A^(-1) = A^(-1)^T * A * A^(-1), which implies (A^(-1))^T = A^(-1).

Therefore, we have proved that the inverse of an invertible symmetric matrix A, denoted as A^(-1), is also a symmetric matrix.

Answer:

11/20 is closer to 1/2.

Step-by-step explanation:

To see why, we can look at the number line. The midpoint between 0 and 1/2 is 1/4, and the midpoint between 1/2 and 1 is 3/4. 11/20 is greater than 1/2, but it is closer to 1/2 than it is to 3/4.

Another way to check is to find the distance between 11/20 and each of the values. The distance between 11/20 and 1/2 is 1/20, while the distance between 11/20 and 1 is 9/20. Since 1/20 is smaller than 9/20, 11/20 is closer to 1/2 than it is to 1.
