4/4 is the most commonly used time signature. You will have 4 beats per measure and the quarter note will be one beat.

Two numbers make up a time signature, which is similar to a fraction. The time signature may alter throughout a work, but it always appears at the beginning. The bottom number is the note value that corresponds to one beat, and the top number is the number of beats in a measure. A song in 4/4 time, for instance, will have four quarter notes every measure, whereas a song in 9/8 time will have nine eighth notes per measure.

Here,

The most popular time signature is 4/4. The quarter note is one beat, and each measure has four beats.

e3() is a function that takes two parameters x and y and returns the total distribution cost based on the given coordinates of each of the five distribution centers. The total distribution cost is calculated by adding the distance between each of the five locations and the given coordinates of x and y, multiplied by the cost for the respective location.

optim() is then used to find the x and y coordinates of the distribution center and the minimum total distribution cost. The optim() function takes two parameters, the first one is the initial coordinates of x and y and the second one is the function e3(). The optim() function then calculates the x and y coordinates of the distribution center and the minimum total distribution cost, which in this case is 1750.

The scale factor of Dilation is 2

The ratio of the scale of an original object to a new object that is a representation of it but is a different size is known as a scale factor.

We want to find the scale factor at which QRST is dilated to form Q'R'S'T'

We will find that the scale factor is 2.

In a general dilation, we will see that all the measures change in the same way, by the scale factor.

This means that:

QR*k = Q'R'

RS*k = R'S'

And so on, where k is the scale factor.

Then we can just find one of the equivalent measures in both trapezoids and find the value of k.

For example, we have:

Q'R' = 8

QR = 4

Replacing these on the above equation we get:

4*k = 8

k = 8/4 = 2

k = 2

Therefore the scale factor of dilation is 2.

The inequality on the graph can be written as:y ≥ -x + 4

On the graph, we have a linear inequality. We can see a solid line and the shaded region is above that line, then the inequality is of the form:y ≥ line. Let's find the equation for the line.

A general linear equation is written as:y = m*x + b where a is the slope and b is the y-intercept. If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:m = (y₂ - y₁)/(x₂ - x₁)

We can use two points on the line on the graph, I will use the intercepts that are (0, 4) and (4, 0)So the slope is:m = (0 - 4)/(4 - 0) = -1

And the y-intercept is 4, then the line is:-1*x + 4-x + 4 and thus, the inequality is:y ≥ -x + 4

The value of [p] will be p = - 1.46. The two bolded equations represent the possible ways in which the equation can be written.

We have the following equations -

2.3p - 10.1 = 6.5p - 4 - 0.01p

2.3p - 10.1 = 6.49p - 4

2.3p - 10.1 + 4 = 6.49p

Let's call the smaller number "x" and the larger number "y." Since 7 is added to the larger number, y + 7 = 4x. Since 28 is added to the smaller number, x + 28 = 2y.

We can solve this system of equations by substituting the first equation into the second equation to eliminate one of the variables:

x + 28 = 2(y + 7)

x + 28 = 2y + 14

x - 2y = -14

Then, we can substitute the second equation into the first equation to eliminate the other variable:

y + 7 = 4(x + 28)

y + 7 = 4x + 112

y - 4x = -105

Now we have a system of two equations in two variables, which we can solve using methods such as substitution or elimination. Let's use substitution:

x - 2y = -14

y - 4x = -105

If we solve the second equation for y, we get y = 4x - 105. Substituting this expression into the first equation gives:

x - 2(4x - 105) = -14

x - 8x + 210 = -14

-7x = -224

x = 32

Substituting this value back into the expression for y gives us y = 4(32) - 105 = 107.

Therefore, the two numbers are x = 32 and y = 107. If 7 is added to the larger number, the value obtained is 107 + 7 = 114, which is four times the smaller number (32). If 28 is added to the smaller number, the value obtained is 32 + 28 = 60, which is twice the larger number (107).

The cost of 4.25 grams of potatoes is £0.00238

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

2.5kg of potatoes cost £1.40

This means that the unit rate can be calculated as

Unit rate = Cost/Amount

So, we have the following representation

Unit rate = 1.40/2.5

The cost of 4.25 grams is calculated as

Cost = Unit rate * Amount

So, we have the following representation

Cost = 4.25 * 1.40/2.5

Convert to grams

Cost = 4.25 * 1.40/2500

Evaluate

Cost = 0.00238

Answer:

Step-by-step explanation:

76% of 50 is 38

Answer: 38 games

Step-by-step explanation: The answer is actually pretty simple to get to. You just need to find 76% of 50. Let x be the amount of games they have won this year. The equation is: x= 0.76*50. Why it is 0.76 instead of 76 is because percent is always out of 100 that is why the max is 100%. So 0.76 is the same as 76/100 which is also 76%. Back to the equation: x = 0.76*50. If you solve the equation which is just 0.76*50, you would get 38. 38 is how many games they won in the season.

What is a triangle?

Triangle is bounded area by three sides. If length of all sides is not equal, then the triangle is known as an obtuse triangle.

The vertices of the triangle are A(-4,4), B(4,4), and C(4,-2)

The length of line segment AB is √[(4 - (-4))² + (4 - 4)²] = √8² = 8 units

The length of line segment BC is √[(4 - 4)² + (-2 - 4)²] = √6² = 6 units

The length of line segment AC is √[(4 - (-4))² + (-2 - 4)²] = √[8² + 6²] = √100  = 10 units.
