Step-by-step explanation:

The estimate of 179% of 41 by rounding is about 73.19.

To find this estimate, first convert the percentage to a decimal by dividing it by 100: 179/100 = 1.79. Then, multiply this decimal by 41: 1.79 * 41 = 73.39.

Answer:

B. \( 4x^2 + \frac{3}{2}x - 7 \)

Step-by-step explanation:

\( f(x) = \frac{x}{2} - 3 \)

\( g(x) = 4x^2 + x - 4 \)

(f + g)(x) = f(x) - g(x)

= \( \frac{x}{2} - 3 + 4x^2 + x - 4 \)

Add like terms

\( = 4x^2 + \frac{x}{2} + x - 3 - 4 \)

\( = 4x^2 + \frac{3x}{2} - 7 \)

Answer:

\( \huge{ \boxed{m = \frac{3}{2} }}\)

Step-by-step explanation:

\( - 15x + 10y = 50\)

Equation of a line is given by

\( \bold{y = mx + c}\)

where

m is the slope

c is the y intercept

To find the slope, we must first rewrite the equation in the given form y = mx + c and compare both equations.

\( - 15x + 10 y = 50 \\ \\ 10y = 15x + 50 \\ \\ \frac{10y}{10} = \frac{15}{10} x + \frac{50}{10} \\ \\ y = \frac{3}{2} x + 5\)

Comparing it with the general equation y=mx + c,

\(m = \frac{3}{2} \\ \)

An absolute value is the numerical value of a number without consideration of its sign. It can be represented graphically by a straight line known as a number line. Absolute value equations are equations that include absolute values of variables or unknown quantities. The following are examples of how to write an absolute value equation in the form |x-c|=d to fit the provided solution sets:

Example 1:

Solution set: {x|x≤-3 or x≥1}
Absolute value equation: |x-(-1)|=4
Explanation: -1 is the midpoint of the two ranges (-3 and 1) in the solution set. |x-(-1)|=|x+1| is the absolute value expression for the midpoint -1. The distance d from -1 to the solutions' furthest endpoints, 1 and -3, is four, hence the value of d in the absolute value equation is 4.

Answer:

A.  4

Step-by-step explanation:

Given inequality:

\(x+9 < 4x\)

Rearrange the inequality to isolate x.

Subtract x from both sides of the inequality:

\(\begin{aligned}x+9-x & < 4x-x\\9& < 3x\end{aligned}\)

Divide both sides of the inequality by 3:

\(\begin{aligned}\dfrac{9}{3}& < \dfrac{3x}{3}\\\\3& < x\\\\x& > 3\end{aligned}\)

So the values of x that make the inequality true are:

Therefore, from the given answer options, the value of x that makes the inequality true is x = 4.

To check this, substitute x = 4 into the inequality:

\(\begin{aligned}x+9& < 4x\\x=4\implies 4+9& < 4(4)\\13& < 16\end{aligned}\)

As 13 is less than 16, the inequality is true when x = 4.

A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of 11/2 inch. So, the correct answer is (D).

To determine the correct answer, we need to compare the diameters of the two pipes and understand the relationship between pipe diameter and threads per inch.

The number of threads per inch generally decreases as the pipe diameter increases. This means that a larger pipe diameter will have fewer threads per inch compared to a smaller pipe diameter.

Given that the first pipe has a diameter of 1 1/4 inches, we need to find the pipe diameter from the options that is larger than 1 1/4 inches.

The option that meets this requirement is D. 11/2. This represents a pipe diameter of 1 1/2 inches. Therefore, a pipe with a diameter of 1 1/2 inches should have fewer threads per inch than a pipe with a diameter of 1 1/4 inches. Therefore, the correct answer is D. 11/2.

Carson's work is correct for solving the equations.

Given that;

Carson wants to solve this system of equations.

y = x² + 5x − 6

y = x − 1

Now, We can solve first equation as;

y = x² + 5x - 6

y = x² + 5x - 6 = 0

⇒ x = - 5 ± √5² - 4×1×- 6 / 2

⇒ x = - 5 ± √25 + 24 / 2

⇒ x = - 5 ± √49 / 2

⇒ x = - 5 ± 7/2

⇒ x = - 5 + 7 / 2

⇒ x = 2/2

⇒ x = 1

⇒ x = - 5 - 7 / 2

⇒ x = - 12 / 2

⇒ x = - 6

Hence, From (ii);

⇒ y = x - 1

At x = 1;

y = 1 - 1

y = 0

At x = - 6;

y = - 6 - 1

y = - 7

Hence, Carson's work is correct.

Answer:

v (E) = √(2E/m)

Step-by-step explanation:

From the question given:

E = ½mv²

E is the kinetic energy

m is the mass of object

v is the velocity.

To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.

This can be obtained as follow:

E = ½mv²

Cross multiply

mv² = 2E

Divide both side by m

v² = 2E/m

Take the square root of both side

v = √(2E/m)

Therefore, the model v(E) for the velocity of the object is given by:

v (E) = √(2E/m)

Step-by-step explanation:

In summary in axis when x = 24, y = 41.1667.

Why is it?

If y varies inversely as x, then y = k/x for some constant k. To find k, we can use the initial values given:

y = k/x

38 = k/26

k = 38×26

k = 988

Now we can use k to find y when x = 24:

y = k/x

y = 988/24

y = 41.1667 (rounded to four decimal places)

Therefore, when x = 24, y = 41.1667.

In mathematics, an axis is a straight line that defines a reference direction for a coordinate system. It is used to locate or plot points, and describe geometric shapes in a plane or in space. In a two-dimensional coordinate system, there are two axes: the x-axis, which is horizontal, and the y-axis, which is vertical.

Answer: The median is one of several measures of center that can be used to summarize a dataset. The median is the middle value in a set of data when the data is arranged in order from smallest to largest. The median divides a dataset into two equal parts, with half of the data values being smaller than the median and half being larger.

Step-by-step explanation:

The median is one of several measures of center that can be used to summarize a dataset. The median is the middle value in a set of data when the data is arranged in order from smallest to largest. The median divides a dataset into two equal parts, with half of the data values being smaller than the median and half being larger.

The reason why the median can differ relative to the data set is because it is affected by extreme values, or outliers, in the data. For example, if a dataset has a few very large or very small values, the median can be significantly different from the mean (another measure of center), which is affected by all values in the dataset. In these cases, the median provides a better measure of center because it is less sensitive to outliers.

In general, the median is considered the best measure of center when the data is skewed (not symmetrical) or has outliers. In these cases, the median provides a better representation of the "typical" value in the dataset. However, when the data is symmetrical and does not have outliers, the mean can be a good measure of center because it takes into account all values in the dataset.

In conclusion, the best measure of center depends on the shape and distribution of the data. When the data is skewed or has outliers, the median is the best measure of center, while in symmetrical and non-outlier datasets, the mean can provide a good measure of center.

Step-by-step explanation:

3×60 + 25 = 205

therefore 3 minutes and 25 seconds is 205 seconds

The average speed on the first 30 minutes is 0.2 km per min.

Here we have the graph for the position of a bycicle rider on a 42-minute trip.

On the vertical axis we can see the position, and on the horizontal axis we can see the time.

Remember that:

speed = distance/time.

To find the average speed on the first 30 min, we need to take the quotient between the position after 30 minutes and 30 min.

At 30 min we can see that the position is at 6 km, then the speed will be:
