Parallelograms and trapezoids are both two-dimensional shapes with four sides. While they share similarities, there are some key differences between the two that help to distinguish them from each other. In this essay, we will discuss the key differences between parallelograms and trapezoids and explore how these differences can help us to identify each shape.

A parallelogram is a two-dimensional shape with four sides and two sets of parallel lines. It is a quadrilateral with opposite sides parallel to each other and opposite angles equal. A parallelogram can also have opposite sides of equal length, which is known as a rhombus. Examples of shapes that are parallelograms include squares, rectangles, and rhombuses.

A trapezoid is also a two-dimensional shape with four sides. However, unlike a parallelogram, a trapezoid only has one set of parallel lines. The two non-parallel sides of a trapezoid are called the legs, while the two parallel sides are called the bases.

Answer:

f(x) = [tex]\frac{-1}{3}[/tex] x - 3

Step-by-step explanation:

The slope is -1/3.  Start at the point (0,-3).  From that point go up 1 and 3 left and you will be back on the line at point (-3,-2).  The slope is negative because if you start on the very left of the graph and follow the line, you are going down hill.

The y-intercept is -3.  This is where the line crosses the y axis (0,-3).

a) There are 700 x 36/100 = 252 students who use public transport.

b) There are 700 - 250 = 450 female students in the school. The percentage of female students in the school is 450/700 x 100% = 64%.

The solution for this system of equations is x = 6 and y = 0.

What is the solution to the linear equation?

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

We can solve this system of equations using the elimination method, or substitution method.

With the elimination method, we would multiply one equation by a constant so that we can eliminate one of the variables when we add the two equations together.

First equation: x − 4y = 6

Second equation: 2x + 2y = 12

We multiply the first equation by 2

2x - 8y = 12

Now we can add the two equations:

2x - 8y = 12

2x + 2y = 12

4x - 6y = 24

Now we can solve for x in this equation:

4x = 24 + 6y

x = 6 + 3/2 y

Substituting that value of x back into the first equation

x - 4y = 6

6 + 3/2y - 4y = 6

3/2y = 0

y = 0

Substituting y back into x = 6 + 3/2y

x = 6

Hence, The solution for this system of equations is x = 6 and y = 0.

The group that has a higher percentage is the low income voters.

A percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100.

In this case, 60 out of a sample of 70 high income voters. The percentage will be:

= 60/70 × 100.

= 85.7%

Also, 90 out of a sample of 100 low income voters supported the introduction of a new national security tax. The percentage will be:

= 90/100 × 100

Step-by-step explanation:

In this case, the unit rate would be:

Unit rate = 180 miles / 3 hours

Unit rate = 60 miles/hour

Answer:

60 miles per hour

Step-by-step explanation:

Given is 180 miles in 3 hours.

We know that unit rate is written as x miles per hour or we can say x miles in one hour. So in order to find the unit rate for the above rate we can express the data in fraction form as,

180miles3hours

Now to make the denominator 1 and not change the given ratio we will divide both the numerator and denominator by 3.

=180miles÷33hours÷3

On dividing we get,

=60miles1hour

Thus we get 1 in denominator or this is the only unit rate.

Thus our answer is 60 miles per hour.

Answer:

Degree? 2nd

Step-by-step explanation:

We are given two terms which are 3x² and -x. This makes the polynomial a binomial (because bi- means two). Additionally, the leading degree of the polynomial is 2 because that is the greatest exponent in the expression, so it's a second-degree binomial.

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

A function and a set of input values

The equation of the function is given as

f(x)={x2−14+|x−6|if x<2if x≥2

Express properly

So, we have

f(x) = {x² − 14 +|x − 6| if x < 2

        { 0 if x≥2

The function input values are given as

f(−1) , f(0) , f(2) , and f(4) .

Substitute the known values in the above equation, so, we have the following representation

For f(-1), we make use of f(x) = x² − 14 +|x − 6|

So, we have

f(-1) = (-1)² − 14 +|-1 − 6|

Evaluate

f(-1) = -6

For f(0), we make use of f(x) = x² − 14 +|x − 6|

So, we have

f(0) = (0)² − 14 +|0 − 6|

Evaluate

f(0) = -8

For f(2) and f(4), we have

f(2) = 0 and f(4) = 0

Hence, the values are f(-1) = -6, f(0) = -8, f(2) = 0 and f(4) = 0

The length of ED is 6. The solution is obtained using triangle proportionality theorem.

What is triangle proportionality theorem?

According to triangle proportionality theorem, a triangle's other two sides are divided in the same proportion if a line drawn parallel to either one of its sides intersects the other two sides at two different spots.

In the figure, BE║CD

So, by using the basic proportionality theorem, we get

AB/BC = AE/ED    ...(i)

We are given AB= 15, BC= 5 and AE=18

So, on substituting these values in (i), we get

⇒15/5 = 18/ED

⇒3 = 18/ED

Answer:

x = 2

Step-by-step explanation:

using the properties of logarithms

• logx - logy = log ([tex]\frac{x}{y}[/tex] )

• loga = log b ⇒ a = b

given

ln x - ln 2 = ln 3 - ln(x + 1)

ln ([tex]\frac{x}{2}[/tex] ) = ln( [tex]\frac{3}{x+1}[/tex] )

[tex]\frac{x}{2}[/tex] = [tex]\frac{3}{x+1}[/tex] ( cross- multiply )

x(x + 1) = 6

x² + x = 6 ( subtract 6 from both sides )

x² + x - 6 = 0 ← in standard form

(x + 3)(x - 2) = 0 ← in factored form

equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = 0 3

x - 2 = 0 ⇒ x = 2

but x > 0 , then x = 2

When 7/8 of the candy bar is split into 3/10 of the bar, the candy bar can make around 2 servings.

In mathematics, a fraction is represented by a number that identifies a portion of a whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Given that there is 7/8 of the candy bar. The bar is needed to be further divided into 3/10 of the bar, this can be calculated as follows:

[tex]\frac{\frac{7}{8} }{\frac{3}{10} } = \frac{7}{8} * \frac{10}{3} = 2.91[/tex]
