If a=6 and b=24 what is (a+b)^2

Answer:

If 200 is four qoaters, then 1 quater is 200/4 is 50. so 50 ice creams is strawberry. One quater in procantage is 25%.

after that you count how many ice crams are vanilia

\(\frac{42}{200}\) after you divide it  you get 0.21 which is 21%

After you just deduct 25+21 from 100

you get

100-46=54

the answer is 54%

Answer: $1,634.62

Step-by-step explanation:

There are 52 weeks in a year. However, Sean does not get paid every week, he gets paid every other week. 52/2 = 26, thus he gets paid 26 times a year.

His annual salary is 42,500. To figure out his salary in each paycheck, divide the net salary by the number of pay periods per year. In this case 42,500/26.

42500/26 = 1,634.62 (rounded to the nearest cent)

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The set of points that lies on the graph of the function is A, {(0, 0), (-1, -1), and (1, 1)}.

This can be verified by plugging the points into the equation y = x. When x = 0, y = 0. When x = -1, y = -1. Finally, when x = 1, y = 1. Therefore, all three points lie on the graph.

To verify this further, we can calculate the slope of the line using two points. The slope of the line is calculated by taking the difference in the y-values and dividing by the difference in the x-values. For example, to calculate the slope between the points (0, 0) and (-1, -1), we take the difference in the y-values (-1 - 0) and divide it by the difference in the x-values (-1 - 0). This results in the slope being -1. Since the slope is -1, this means that the points are lying on the graph of the function  y = x.

The 1-hour change factor for the number of bacteria is 1.019.

In mathematics, a factor refers to a number or algebraic expression that divides another number or algebraic expression exactly, without leaving any remainder.

To find the 1-hour change factor, we need to calculate the ratio of the number of bacteria at 8 hours to the number of bacteria at 0 hours raised to the power of 1/8, which gives the change factor for a single hour.

Given by the question.

First, we need to adjust the number of bacteria at 8 hours using the given factor of 1.829:

B(8) = 256/1.829 = 140.1 (rounded to the nearest tenth)

Now we can calculate the 1-hour change factor:

[\((B(8)/B(0))^{1/8}\)] = [\((140.1/140^{1/8}\)] = 1.019

Rounding to the nearest thousandth gives the final answer:

1.019 (rounded to three decimal places).

Answer:4

Step-by-step explanation:jus done this question

Sum of the interior angles of any triangle equal 180° .

Thus ;

\(x + 2x + x + 8 = 180\)

\(4x + 8 = 180\)

Subtract sides -8

\(4x + 8 - 8 = 180 - 8\)

\(4x = 172\)

Divided sides by 4

\( \frac{4}{4}x = \frac{172}{4} \\ \)

\(x = 43\)

So the angles are :

x = 43°

2x = 2 ( 43 ) = 86°

x + 8 = 43 + 8 = 51°

Thus the order from least to greatest ,

is : 43° , 51° , and 86°

A formula for the function g(x) obtained when the graph of f(x) = 1/x is shifted down 7 units and to the right 5 units is g(x) = 1/(x - 5) - 7.

In Mathematics, the translation a geometric figure or graph to the right simply means adding a digit to the value on the x-coordinate of the pre-image or function.

In Mathematics, a horizontal translation to the right is modeled by this mathematical expression g(x) = f(x - N) while a vertical translation to the negative y-direction (downward) is modeled by this mathematical expression g(x) = f(x) - N.

Where:

By translating the graph of f(x) = 1/x down 7 units and 5 units to the right , we have:

g(x) = f(x - 5) - 7

g(x) = 1/(x - 5) - 7

Step-by-step explanation:

With 98% confidence, we can say that the population variance is between 7.36 and 71.09.

What is probability?

Probability is a branch of mathematics that deals with the study of chance or randomness in events. It is a measure of the likelihood of an event occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To construct the confidence interval for the population variance, we will use the chi-squared distribution.

First, we need to calculate the chi-squared values for the lower and upper bounds of the confidence interval using the following formulas:

χ²_L = (n - 1) * s² / χ²(α/2, n-1)

χ²_U = (n - 1) * s² / χ²(1-α/2, n-1)

where n is the sample size, s² is the sample variance, α is the level of significance, and χ²(α/2, n-1) and χ²(1-α/2, n-1) are the chi-squared values with α/2 and 1-α/2 degrees of freedom, respectively.

Substituting the given values, we get:

χ²_L = (9 - 1) * 17.3 / χ²(0.01, 8) ≈ 3.355

χ²_U = (9 - 1) * 17.3 / χ²(0.99, 8) ≈ 29.587

Next, we can use these chi-squared values to construct the confidence interval for the population variance:

(V_L, V_U) = [(n - 1) * s² / χ²_U, (n - 1) * s² / χ²_L]

Substituting the given values, we get:

(V_L, V_U) = [(9 - 1) * 17.3 / 29.587, (9 - 1) * 17.3 / 3.355]

Simplifying, we get:

(V_L, V_U) ≈ [7.36, 71.09]

Therefore, with 98% confidence, we can say that the population variance is between 7.36 and 71.09.

The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.

To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.

Starting with -4x + y = -3, we isolate y by adding 4x to both sides:

y = 4x - 3

Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.

If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:

y > 4x - 3

If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:

y < 4x - 3

The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.

For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.

Constructing an angle bisector using only a straightedge and compass involves drawing the Angle, creating two arcs that intersect the angle, and using those arcs to create a line segment that bisects the angle.

To construct an angle bisector using a straightedge and compass, there are several steps that you need to follow. The correct order of steps for constructing an angle bisector of ABC using only a straightedge and compass are listed below:

Step 1: Draw the angle ABC with a straightedge.

Step 2: Place the point of the compass on point B and swing an arc that intersects both lines that make up the angle. Label the two points where the arc intersects the angle as points D and E.

Step 3: Without changing the compass width, place the point of the compass on point D and swing an arc that intersects the ray that extends from point B. Label the point of intersection as point F.

Step 4: Without changing the compass width, place the point of the compass on point E and swing an arc that intersects the ray that extends from point B. Label the point of intersection as point G.

Step 5: Draw the line segment FG with a straightedge. This line segment is the angle bisector of angle ABC.

In summary, constructing an angle bisector using only a straightedge and compass involves drawing the angle, creating two arcs that intersect the angle, and using those arcs to create a line segment that bisects the angle. Following these steps will allow you to construct the angle bisector of ABC accurately.

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is f ( x )

The function has two ranges for a given domain
