Proportionality can be used to find the length of side DE in the triangle by multiplying both sides by EB and dividing both sides by FC. This yields the equation DE = (FC * DF) / EB. Simplifying this equation yields DE = 31.72.

EF is parallel to BC and DF, EB, FC are given.

We can use the theorem that states:

Parallel lines have corresponding angles congruent and corresponding sides proportional.

We may use proportionality to get the length of the triangle's side DE. When two ratios are equal, this is referred to as proportionality. In this scenario, we will use the ratios of side DE to side FC and side EB to side DF. Given that side DE is proportional to side FC and side EB is proportionate to side DF, we can construct an equation stating that the ratio of side DE to side FC equals the ratio of side EB to side DF. This equation is written as DE/FC = DF/EB.

We can then solve this equation for side DE by multiplying both sides by EB and dividing both sides by FC.

This yields the equation DE = (FC * DF) / EB.

We can then plug in the given values for FC, DF, and EB to find the length of side DE.

When we do this, we get that DE = (15.4 * 20.6) / 19.3.

Simplifying this equation yields DE = 31.72.

Rounding to the nearest tenth, DE = 31.7. This is the length of side DE in the triangle.

The required function here is   C(x) =2.2x

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: One bag weighs 2.4 pounds and costs $5.28. Another bag weighs 2.7 pounds and costs $5.94.

One bag weighs 2.4 pounds and costs $5.28.

and therefore 1 pound weighing bag will cost = 5.28/2.4

                                                                             =$2.2

I wish you luck in your assignments.

The additive inverse of 7 11 is -7 11, which is the same number but with the opposite (or negative) sign. This means that when added together the two numbers will total zero.

Additive inverse of 7 11 = -7 + 11 = -7 11

The additive inverse of a number is the same number with the opposite sign, which can be helpful when solving equations. For example, if we have the number 7 11, the additive inverse would be -7 11. To find the inverse, we simply switch the sign from positive to negative (or vice versa). This means that when the two numbers are added together, the total sum will be zero. For example, 7 11 + (-7 11) = 0. The inverse of a number can also be helpful when we are looking for an unknown variable in an equation. For example, if we have the equation 3x + 7 11 = 4, we can find the value of x by subtracting 7 11 from both sides:

3x + 7 11 = 4 --> 3x

= -7 11 + 4 --> 3x

= -3 11 --> x = -1 11.

This means that x = -1 11.

To solve the 3 step equation, we have to solve the one equation in two variable. Then substituting the value in other equation and further solving according to the given rule.

In the substitution approach, we will examine the two equations and choose which variable is the most straightforward to solve for in order to transform one of the equations into x =, y =, or z =. The other equation's x, y, or z will then be appropriately replaced. The outcome will be an equation we can solve that has just one unknown. A variable whose coefficient is 1 or -1 should be isolated.

Use the steps below to solve systems using substitution:

(1) Choose an equation and determine the value of one of its variables.

(2) Substitute the variable you just solved in the other equation.

(3) Address the fresh equation.

(4) Enter the discovered value into any equation that calls for both variables, then get the value for the other one.

If a lever was used with an effort arm of 12 meters and a load arm of 6 meters, the work that would have been done would've been (A) 50 J.

Using a lever makes work simpler and quicker since it only takes a bit of effort to move a heavy load.

The efficiency of the machine goes up when the output force is bigger than the input force - the formula for this is Output Force divided by Input Force.

Eff = ( output force/input force ) x 100 %

The amount of force you get is determined by this equation.

F ( out ) = load x distance moved by the load

The force you put in is calculated using this equation.

F ( input ) = effort x distance moved by the effort

If we had used a lever with an effort arm of 12 meters and a load arm of 6 meters, the work that would have been done could be calculated.

work = ( 600   x 6  ) / ( 12  x 6  )

work = 50 J

Therefore, if a lever was used with an effort arm of 12 meters and a load arm of 6 meters, the work that would have been done would've been (A) 50 J.

The two different types of factor analysis are confirmatory and exploratory.

A technique for simulating observed variables and their covariance structure in terms of unseen variables is component analysis (i.e., factors). The two different types of factor analysis are confirmatory and exploratory.

A key phase in the scale building process is exploratory factor analysis (EFA), which is a technique to examine the underlying structure of a group of observed variables. Factor extraction is EFA's first stage. We will talk about how principal components analysis and common factor analysis approach variance partitioning differently.

Confirmatory factor analysis (CFA), a technique for confirming a factor structure that has already been developed, will be covered in the seminar's last section. Identification, model fit, and degrees of freedom will be discussed in relation to the three-item, two-item, eight-item, one-factor, and two-factor CFAs.

The center camera and the two angled cameras cover a total of 60° + 60° + 60° = 180°.

The total angle covered by the three cameras is 180°. The center camera has a field of 60° and the other two cameras, which are angled 45° away from the center camera, each has a field of 60°.

Therefore, together, the center camera and the two angled cameras cover a total of 60° + 60° + 60° = 180°.

When two rays are united at a common point, an angle is created. The two rays are referred to as the arms of the angle, while the common point is referred to as the node or vertex. The symbol "°" stands for the angle. The Latin word "Angulus" is where the word "angle" originated.

Typically, an angle is measured with a protractor and expressed in degrees. Angles of 30°, 45°, 60°, 90°, and 180° are shown here. The many types of angles are determined by the angles' degrees values.

The the probability of picking a 2 and then picking a factor of 12 is 1/6.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Sample space = {1, 2, 3, 4}

The probability of just picking up a 1 is 1/4.

Now, the remaining cards = 3

No, segment PQ is not a perpendicular bisector of segment RS. A perpendicular bisector is a line that passes through the midpoint of a segment and is perpendicular to it.

To determine if a line is a perpendicular bisector, we can use the equation (x1 + x2)/2 = xmid and (y1 + y2)/2 = ymid to find the midpoint of the segment and then use the equation y = mx + b to find the equation of the line. If the slope of the line is the negative reciprocal of the slope of the segment, then the line is a perpendicular bisector. In this example, if the coordinates of the endpoints of segment RS are (x1,y1) and (x2,y2), then the midpoint of the segment is (xmid, ymid) where xmid = (x1 + x2)/2 and ymid = (y1 + y2)/2. The equation of the line PQ can be written as y = mx + b. To determine if PQ is a perpendicular bisector, we must calculate the slope of the segment RS and the slope of the line PQ and then compare the two slopes. If the slope of the line PQ is the negative reciprocal of the slope of the segment RS, then PQ is a perpendicular bisector. Otherwise, PQ is not a perpendicular bisector.

Best Market sells strawberries at a cheaper unit price.

The definition of a unit of measurement is a particular magnitude of a quantity that has been established and accepted by law or convention and is used as a standard for measuring other quantities of the same kind. Any other quantity of that type can be expressed as a multiple of the unit of measurement.

For instance, a length is a physical quantity. The metre is a unit of length that corresponds to a particular, predetermined length (symbol m). For instance, "10 metres" (or 10 m) is 10 times the fixed, predetermined length known as "metre."

In best Market, the price y for x pounds of strawberries is given by

y = 2.90x

Lets find the slope of Fine Foods strawberries

y - y₁ = m(x - x₁)

From the graph take two points, lets say (3, 6) and  (5, 10)

Put the points in the formula

10 - 6 = m(5 - 3)

4 = 2m

m = 4/2 = 2

The slope is 2

Now, lets convert it to slope intercept form

y - 10 = 2(x - 5)

y = 2x - 10 + 10

y = 2x - 10 + 10

y = 2x

For a certain same price Fine Foods provides 2x pounds of strawberries while Best Market provides 2.90x pounds of strawberries.

Thus, Best Market sells strawberries at a cheaper unit price.
