Since both angles are supplementary the sum of the angles needs to be 180°

The solutions to the nearest tenth are x = -0.1 and x = 1.3

From the question, we have the following parameters that can be used in our computation:

5x² - 2x - 1 = 4x

Evaluate the like terms

So, we have

5x² - 6x - 1 = 0

Next, we solve using a graph

The graph of 5x² - 6x - 1 = 0 is added as an attachment

From the attached graph, we can see that the curve intersects with the x-axis at x = -0.1 and x = 1.3

This means that the solutions are x = -0.1 and x = 1.3

Answer:

The solutions to the equation 5x^2-2x-1=4x to the nearest tenth are x ≈ 1.3 or x ≈ -0.4.

Step-by-step explanation:

To solve the equation 5x^2-2x-1=4x to the nearest tenth, we can start by moving all the terms to one side of the equation.

5x^2-2x-1=4x

5x^2-6x-1=0

Next, we can use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 5, b = -6, and c = -1.

Plugging these values into the formula gives:

x = (-(-6) ± sqrt((-6)^2 - 4(5)(-1))) / 2(5)

x = (6 ± sqrt(56)) / 10

To make a regular polygon with 96 sides we can take a circle as a starting point and divide it into 96 equal sides.

To create a regular polygon with 96 sides, we must take into account that all its sides must be equal, so we can take a circumference as a starting point. In this case, the circumference has 360°, so we must divide this into 96 parts and the result would be the distance between the edges of the polygon.

In this case, we must make a circle with a protractor and mark every 3.75°, when we have completed this procedure in the entire circumference we will have a regular polygon with 96 sides.

Answer:

b = \(\frac{ln190}{ln200}\)

Step-by-step explanation:

Using the rule of logarithms

log \(x^{n}\) ⇔ nlogx

Given

190 = \(200^{b}\) ( take the natural log ln of both sides )

ln190 = ln\(200^{b}\) = bln200 ( divide both sides by ln200 )

\(\frac{ln190}{ln200}\) = b

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

We must analyze the diagram to find the solution.

adjacent angles are supplementary:

The estimate of the quotient expression using compatible numbers is 31

The quotient expression from the question is given as

925÷29

From the question, we are to make use of compatible numbers

This means that we have the following approximation

925 = 930

29 = 30

Next, we estimate the quotient using approximated values

So, we have

925 ÷ 29 = 930 ÷ 30

Evaluate the quotient

925 ÷ 29 = 31

Hence, the estimate is 31

The Circle Sector Area correct answer is: O n(30in)2

To calculate the area of the sector in the circle, you would typically use the formula:

Area = (θ/360) * π *\(r^2\)

where θ is the angle of the sector in degrees, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle.

From the options you provided, the correct choice would be:

O n(30in)2

This option represents the square of the radius (30in) squared, which gives you the value of \(r^2.\)

Therefore, the Circle Sector Area correct answer is: O n(30in)2

The total sales have to be this month to reach his goal is 5000.

Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.

Given:

A driver set a goal to earn $2,000 in March. He receives a base salary

$1,000 per month as well as a 20% commission for all sales in that money.

According to given question we have

Total earn in the march(y)=$2,000

Base salary per month(c)=$1,000

commission for all sales(m)=20%

Let the total sales be x

By the equation in slope-intercept we have

y=mx +c

2000=0.2x+1000,

subtract 1000 on both sides we get,

1000=0.2x,

Multiply by 5 to get x by itself we get,

5000=x

Therefore, the total sales have to be this month to reach his goal is 5000.

Answer:

The commission rate is 15%

Step-by-step explanation:

commission = commission rate x sales

where the commission rate is expressed as a decimal.

In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:

345 = commission rate x 2300

To solve for the commission rate, we can divide both sides by 2300:

commission rate = 345/2300

Simplifying this expression, we get:

commission rate = 0.15

So, the commission rate is 15%

Answer:

m∠R = 56°

Step-by-step explanation:

2(8x - 12) = 16x - 24

2(3x + 5) = 6x + 10

16x + 6x + 10 - 24 = 360

22x - 14 = 360

22x = 374

x = 17

3x + 5 = 17 x 3 = 51 + 5 = 56

As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.

A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.

For a normally distributed data set with a mean of 0 and a standard deviation of 0.5, the proportion of values between -1 and 1 is most closely related to 68%.

Approximately 68% of the data in a normal distribution lies within one standard deviation of the mean, which explains why. One standard deviation below the mean is -0.5, and one standard deviation above the mean is 0.5 since the mean is 0 and the standard deviation is 0.5. As a result, 68% of the data falls into the range of values between -1 and 1, which is one standard deviation from the mean. The closest estimate of the solution is 68%.
