Therefore ,perimeter of square photo frame = 63.2 centimeter.

The total length of boundary of a closed geometric shape is called perimeter. Different geometric shape has different formula for determining perimeter. For a square shaped object perimeter is the four times of its side length.

Here,

Area of a square photo frame = 250 square centimeter.

We know, area of a square photo frame = square of side length

if side length = s

area = s²

it is given that area of a square photo frame = 250 cm²

250 cm² = s²

s = √250 cm

s = 15.81 cm

side length = 15.81 cm

formula for perimeter = 4× side length

perimeter of frame = 4×15.81 = 63.24 cm

The base of an exponent can be simplified by multiplying it by itself as many times as the exponent indicates. If you want to simplify the base of an exponent in an expression, it would be done by raising the base to the power of the exponent using the notation aᵇ = aa...*a (b times)

The base of an exponent is the number that is being multiplied by itself a certain number of times. The exponent is the number indicating how many times the base is being multiplied by itself.

For example, in the expression 2³, the base is 2 and the exponent is 3. This means that 2 is being multiplied by itself 3 times, or 2 * 2 * 2. The simplified form of this expression is 8.

In general, if the base is 'a' and the exponent is 'b' then the simplified form of the expression is 'a' raised to the power 'b' or aᵇ = aa*...*a (b times)

It's also important to note that when the exponent is 1, the expression can't be simplified anymore. For example, 2¹ = 2, where 2 is the base and 1 is the exponent.

Candidate A is likely to receive 8640 voters if all 18000 voters cast their ballot.

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: The survey results from the sample as

A -240

B-210

C-50

The total number of people surveyed is 500

Now as per the given survey results the voters likely to vote for candidate A is P(A)=240/500

              =12/25

Similarly, the probability that the voters vote for Candidate A and B are

P(A)=210/500

      =21/50

P(B)=1/10

∴ If 18000 voters vote the voters likely to vote for A are

The diagram relating to the scatterplot for the data is attached.

I put the height of people on the x-axis because this is what I am trying to correlate the arm span to. I put the arm span on the y-axis because it is dependent on height.

I used point (60,61) and (70,72) to draw the line of best fit and to get the equation. First, to get the slope I would use the slope formula of m = 72-61/70-60 or 11/10 to get a slope of approximately 1.1. Then I used (60,61) to get the rest of the equation by plugging it in: y-61 = 1.1(x -60). This becomes y-61 = 1.1x - 66. Add 61 to both sides and the final equation is y = 1.1x – 5.

The slope represents the rate of change arm span based on height. The y intercept is the arm span.

Using points (66,68) and points (70,72) I plug each into the equation y=1.1x-5 to figure each out based on the difference from the actual points and get .4 for (66,68) and 0 for point (70,72) so I would say, based on .4 and 0 for these two points that this is a good line of best fit.

Based on this data, for every inch in height, the arm span increases by 1.1 inches.

The equation that has the solution x = -1 is D. 7x+8 = -6x - 5

To find the solution of an equation, we need to find the value of the variable that makes the equation true. In this case, we need to find the value of x that makes the equation 7x+8 = -6x - 5 true.

We can start isolating the x variable by adding or subtracting the same terms on both sides of the equation.

D. 7x+8 = -6x - 5

13x = -13

x = -1

So the solution of the equation is x = -1

We can check if this is the solution by substituting it back in the equation. If the equation is true, both sides will be equal when x is -1.

7x+8 = -6x - 5

7*-1 + 8 = -6*-1 -5

-7+8 = 6 -5

1 = 1 (true)

Therefore, D. 7x+8 = -6x - 5 has x = -1 as the solution.

It depends on the context and the audience. Both describing the solution of a system of linear inequalities in words and showing it using a graph have their own advantages.

An explanation graph is what?

A graph is a representation of the relationship between two variables that are normally measured along one of a pair of axes at right angles.

Describing the solution of a system of linear inequalities in words is often useful when the system is simple and the inequalities are easy to understand. It can be a more straightforward way to explain the solution, especially when the audience is not familiar with reading graphs.

On the other hand, using a graph to show the solution of a system of linear inequalities can be more efficient and effective when the system is more complex and the inequalities are harder to understand. Graphs can provide a visual representation of the solution, which can make it easier for the audience to understand the solution and see how it relates to the original problem. Additionally, it can be easier to find the exact point of intersection between the inequalities by looking at the graph.

Both methods can be useful depending on the situation, so it's best to consider your audience, the complexity of the system, and the goal of your explanation when deciding which method to use.

What is algebraic equation ?

An algebraic equation is a mathematical expression that contains one or more variables, and an equal sign. The goal is to find the value or values of the variables that make the equation true. Algebraic equations can take many forms, such as linear equations, quadratic equations, polynomial equations, and more.

y = −2x + 14

x + 2y = −1

We can use the first equation to solve for y in terms of x:

y = −2x + 14

Now we can substitute this expression for y into the second equation,

x + 2(-2x + 14) = -1

x + (-4x + 28) = -1

-3x = -29

x = 9/3

Answer:

Length = Width = 55

Step-by-step explanation:

Perimeter of rectangle = 2(length + width)

Let x = length; let y = width.

perimeter = 2(x + y)

The perimeter must be 220.

2(x + y) = 220

x + y = 110

y = 110 - x

length = x

width = 110 - x

area = length × width

area = x(110 - x)

area = 110x - x²

A = 110x - x²

Take the first derivative of the area function and set equal to zero. Then solve for x.

A' = 110 - 2x

110 - 2x = 0

2x = 110

x = 55

y = 110 - x = 110 - 55 = 55

Answer: Length = Width = 55

Solving the the provided question we can say that here the surface area will be SA = 2(lb + lh + bh) = 2(108 + 120 + 90) =  636 cm sq.

An indication of the overall space occupied by an object's surface is its surface area. A three-dimensional shape's surface area is the total amount of space that surrounds it. A three-dimensional shape's entire surface area is known as its surface area. The surface area of a cuboid with six rectangular faces may be calculated by adding the areas of each face. As an alternative, you may use the formula below and name the box's dimensions as follows: Surface (SA) = 2lh + 2lw + 2hw. Surface area is a measurement of the entire amount of space filled by a three-dimensional shape's surface (a three-dimensional shape is a shape that has height, width, and depth).

To satisfy the lengths of the two sides of the triangle given in the question, the possible lengths of the third side are any value greater than 7 inches and less than 17 inches but not equal to 5 or 12 inches.

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.

According to the law of the sides of a triangle, the lengths of any two of the triangle's sides added together are always more than the length of the third side. The triangle inequality theorem is another name for this condition.

If we know the lengths of two sides of a triangle, we can use the "triangle inequality theorem" to determine the possible lengths of the third side. The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that the lengths of two sides of a triangle are 5 inches and 12 inches, the length of the third side must be:

Greater than 0 inches

Less than the sum of the other two sides (5 inches + 12 inches = 17 inches)

Greater than the difference between the other two sides (abs(5 inches - 12 inches) = 7 inches)

So the possible lengths of the third side are any value greater than 7 inches and less than 17 inches but not equal to 5 or 12 inches.

& EF is perpendicular to GH.

now, we get,

The slope of GH is ...

G -H = (14, 11) -(8, -13) = (6, 24) = (Δx, Δy)

slope = Δy/Δx = 24/6 = 4

The perpendicular line through F will have a slope of the negative reciprocal of this, or -1/4.

The point-slope form of the equation can be written as ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

The perpendicular line through F is then ...
