Jamie is correct. This is because 41 is a combination of 40 and 1. Salena thinks that the 4 is just a 4, however, the 4 is in the tens place, so the 41 without the 1 is 40. The answer to this 41 times 9 is 369. Not 45.

Step-by-step explanation:

Each skirt is $41

Salena needs 9

(9*40) + (9*1)

Step-by-step explanation:

Linda's net and first term of the expression is correct and the surface area of the attic is 4425 square feet.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given the attic of Linda's home.

Attic is in the shape of triangular prism.

The net that Linda drawn is correct since she expresses all the measurements right in the net.

So, the net Linda drew is correct.

We can find the surface area from the net of the prism.

Net of the prism consists of 2 identical triangles, 2 identical rectangles and a rectangle.

Area of triangle is  \(\frac{1}{2}\) × base × height and that of rectangle = length × width

Area of 2 triangles = 2 × \(\frac{1}{2}\) × 25 × 15 = 25 × 15

Area of rectangles = (45 × 40) + (45 × 25) + (45 × 25)

                               = 45(40 + 25 + 25)

Total surface area = 45(40 + 25 + 25) + (25 × 15)

The first term of Linda's expression, 45(40 + 25 + 25) is correct.

The second term of Linda's expression, (\(\frac{1}{2}\) × 25 × 15) is not correct.

Surface area of the attic = 45(40 + 25 + 25) + (25 × 15)

                                        = 4425 square feet

Hence the surface area of the attic is 4425 square feet.

Answer:

  y = {-1/2x +7 for x < 6; 1/2x +1 for x ≥ 6}

Step-by-step explanation:

You want y = 1/2|x -6| +4 written as a piecewise function.

The absolute value function changes its definition when its argument is negative:

  y = |x|   ⇒   y = -x for x < 0, and y = x for x ≥ 0

This means our piecewise function will have one definition for (x-6) < 0 and another for (x -6) ≥ 0.

The argument is negated in this domain, so we have ...

  y = -1/2(x -6) +4

  y = -1/2x +3 +4

  y = -1/2x +7

The absolute value function is an identity function in this domain:

  y = 1/2(x -6) +4

  y = 1/2x -3 +4

  y = 1/2x +1

Combining these descriptions into one, we have ...

  \(\boxed{y=\begin{cases}-\dfrac{1}{2}x+7&\text{for }x < 6\\\\\dfrac{1}{2}x+1&\text{for }x\ge6\end{cases}}\)

Answer:

When we have a function f(x) = y.

The rate of change between a and b (where a < b) is:

R = (f(b) - f(a))/(b - a)

In this case:

b = 3

a = 1

f(3) = 127

f(1) = 95

R = (127 - 95)/(3 - 1) = 16

The rate of change in that interval is 16.

Equations can have one solution, more than one solution or none at all.

The equation is given as:

\(2(2x - []) + 1 = 17 - 4x\)

Represent the blank with y.

So, we have:

\(-2(2x - y) + 1 = 17 - 4x\)

(a) The missing value when the equation is an identity equation

To do this, we simply solve for y in \(-2(2x - y) + 1 = 17 - 4x\)

Open brackets

\(-4x +2y + 1 = 17 - 4x\)

Collect like terms

\(2y = 17 - 1 + 4x - 4x\)

\(2y = 16\)

Divide both sides by 2

\(y = 8\)

Hence, the equation is an identity when the missing value is 8

(b) The missing value when the equation has one solution

In (a), we have: \(y = 8\)

For the equation to have one solution, variable x must be on either sides of the equation.

i.e. \(nx + y = 8\) or \(y = 8 + nx\), where \(n \ne 0\)

Since x has been eliminated, then the equation can not have one solution.

(c) The missing value when the equation has no solution

In (a), we have: \(y = 8\)

This means that the equation will have no solution when the missing value is not 8

\(y \ne 8\)

Answer: 11,295,063

Step-by-step explanation:

So the different number has a 4 with a value of 40.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To solve this problem, we need to first identify the place value of the digit 4 in the given number.

The digit 4 is in the hundreds place in the number 431.67, so its value is 4 x 100 = 400.

According to the problem statement, the 4 in the different number represents a value which is one-tenth of the value of the 4 in 431.67. Therefore, the value of the 4 in the different number is:

400/10 = 40

To determine the value of the different number, we need to look at the other digits in the number. Since we don't have any information about the other digits, we cannot determine the value of the different number. The answer is that the value of the different number cannot be determined with the information given.

Therefore, So the different number has a 4 with a value of 40.

Question 1:

(a) The equation representing Elaine's total parking cost is:

C = x * t

(b) So the cost of parking for a full 24 hours would be 24 times the cost per hour.

Question 2:

The given system of equations is inconsistent and has no solution.

(a) To represent Elaine's total parking cost, C, in dollars for t hours, we need to know the cost per hour. Let's assume the cost per hour is $x.

(b) If Elaine wants to park her car for a full 24 hours, we can substitute t = 24 into the equation from part (a):

C = x * 24

Question 2:

To solve the linear system:

-x - 6y = 5

x + y = 10

We can use the elimination method.

Multiply the second equation by -1 to create opposites of the x terms:

-x - 6y = 5

-x - y = -10

Add the two equations together to eliminate the x term:

(-x - 6y) + (-x - y) = 5 + (-10)

-2x - 7y = -5

Now we have a new equation:

-2x - 7y = -5

To check the answer, we can substitute the values of x and y back into the original equations:

From the second equation:

x + y = 10

Substituting y = 3 into the equation:

x + 3 = 10

x = 10 - 3

x = 7

Checking the first equation:

-x - 6y = 5

Substituting x = 7 and y = 3:

-(7) - 6(3) = 5

Step-by-step explanation:

Given

\(tan(0).tan(1).tan(2).......tan(89) = 0\)

Required

True or false? With reason

The expression is true and the reason is as follows.

In trigonometry:

\(tan(0) = 0\)

So:

\(tan(0).tan(1).tan(2).......tan(89) = 0\)

is equivalent to:

\(0 * [tan(1).tan(2).......tan(89)] = 0\)

When 0 is multiplied to an expression, the result is 0

So, the above expression becomes:

\(0 = 0\)

The answer is (d) a graph of a line that passes through the points (-3, 1) and (0, -5) which satisfies the linear equation  y = −5x − 2.

An equation is mathematical statement that show that two expression are equal. It consists of two sides, a left-hand side and a right-hand side, separated by an equal sign (=)

To determine which graph represents the linear equation y = −5x − 2, we need to compare the equation with the equation of a line in slope-intercept form, which is y = mx + b,

In the given equation y = −5x − 2, the slope is -5 and the y-intercept is -2. Therefore, the equation  in slope-intercept form as y = -5x - 2.

Now, we can compare this with the given options:

a) A graph of a line that passes through the points (-1, 3) and (0, -2)

 equation of a line in slope-intercept form m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-1, 3) and (x2, y2) = (0, -2)

m = (-2 - 3) / (0 - (-1)) = -5/1 = -5

The slope of the line passing through these points is -5, which matches the slope of the given equation. However, the y-intercept of the line passing through these points is not -2, which means that this graph does not represent the given equation.

b) A graph of a line that passes through the points (-2, -2) and (0, -3)

 equation of a line in slope-intercept form m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-2, -2) and (x2, y2) = (0, -3)

m = (-3 - (-2)) / (0 - (-2)) = -1/2

The slope of the line passing through these points is not -5, which means that this graph does not represent the given equation.

c) A graph of a line that passes through the points (-4, -1) and (0, -2)

equation of a line in slope-intercept form m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-4, -1) and (x2, y2) = (0, -2)

m = (-2 - (-1)) / (0 - (-4)) = -1/4

The slope of the line passing through these points is not -5, which means that this graph does not represent the given equation.

d) A graph of a line that passes through the points (-3, 1) and (0, -5)

equation of a line in slope-intercept form m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-3, 1) and (x2, y2) = (0, -5)

m = (-5 - 1) / (0 - (-3)) = -2

The slope of the line passing through these points matches the slope of the given equation. Additionally, the y-intercept of this line is -2, which also matches the y-intercept of the given equation.

Therefore, the answer is (d) a graph of a line that passes through the points (-3, 1) and (0, -5).

The length of the side x is approximately 11.2 units.

A triangle is a three-sided polygon that is formed by connecting three non-collinear points in a plane. The three sides of a triangle are line segments that connect the vertices (corner points) of the triangle. The angles formed by the intersection of the sides are called interior angles of the triangle.

There are different ways to classify triangles based on their sides and angles. Based on sides, a triangle can be:

Equilateral: all three sides are equal in length.

Isosceles: two sides are equal in length.

Scalene: all three sides are of different lengths.

Based on angles, a triangle can be:

Acute: all three angles are acute (less than 90 degrees).

Right: one angle is a right angle (exactly 90 degrees).

Obtuse: one angle is obtuse (greater than 90 degrees).

In a right triangle, the side opposite the 68-degree angle is the hypotenuse, and the side adjacent to the 68-degree angle is the adjacent side. Therefore, we can use the trigonometric function cosine to find the length of the hypotenuse.

cos(68°) = adjacent/hypotenuse

cos(68°) = x/hypotenuse (since the adjacent side has length x)

We can rearrange the equation to solve for the hypotenuse:

hypotenuse = x/cos(68°)

Using a calculator, we can evaluate the expression for cos(68°) and substitute the given value for x to find the length of the hypotenuse:

hypotenuse = x/cos(68°) ≈ 36.9/x

Therefore, the length of the hypotenuse is approximately 36.9/x. We also know that the length of the other leg is 12. Using the Pythagorean theorem, we can find x:

x² + 12² = (36.9/x)²

Expanding the right side and simplifying, we get:

x⁴ - 15,129.6 = 0

Solving for x using a calculator, we get:

x ≈ 11.2 or x ≈ -11.2

Since x represents a length, it must be positive, so we take the positive value rounded to the nearest tenth:

x ≈ 11.2

Therefore, the length of the side x is approximately 11.2 units.
