and makes 4 1/2 servings. How many cups of milk
are needed for 16 servings?

The percentage of those that don't travel by car will be 44%.

It's important to note that a percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, 14 students travel by car and 11 don't travel by car. The total number of students will be:

= 11 + 14.

= 25

Therefore, the percentage of those that don't travel by car will be:

= 11 / 25 × 100

= 44%

The percentage is 44%.

The cost of one day-Lilly is found to be $4 and the cost of one geranium is found to be $8. Therefore, Paul spent about $16 for day-Lilly and $56 for geranium. And Megan spent about $40 for day-Lilly and $88 for geranium.

Two or more algebraic equations that have a common variable and are solved simultaneously are referred to as simultaneous equations. We can find the answers to both unknowns if we have two separate equations with the same two unknowns in each. Here, we'll employ the addition-and-subtraction or elimination method.

Let's consider the cost of day-Lilly as x and the cost of geranium as y. The cost spent by Paul is written as 4x+7y=$72 and Megan is written as 10x+11y=$128.

Solving these two equations for x and  y,

[tex]\begin{aligned}40x+70y = \$720\\\underline{40x+44y=\$512}\\26y=\$208\\y=\$8 \end{aligned}[/tex]

Substitute the value of y in equation 4x+7y=$72 to get the value of x,

Answer:

x = 3

Step-by-step explanation:

4 + x = 7  Subtract 4 from both sides of the equation

4 - 4 - x = 7 - 4  Simplify

x = 3  X equals 3

Answer:

x = 3

Step-by-step explanation:

4 + x = 7

x + 4 - 4 = 7-4 = 3

x = 3

To solve for x, subtract 4 from both side of the equation.  This leaves x by itself on the left side of the equation.  Next subtract 4 from 7 to get the solution, x = 3.

The coordinate of the vertex B after the transformation of the given trapezoid is (-2, 2).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

As per the given graph, the coordinate of vertex B is (-5, 4).

After the translation (x, y) → (x + 3, y - 2), the new coordinate can be obtained as,

(-5, 4) → (-5 + 3, 4 - 2)

⇒ (-2, 2)

Hence, the coordinate of B after the transformation is (-2, 2).

Answer:

9 $50 bills and 6 $20 bills

Step-by-step explanation:

Let f = number of $50 bills.

Let t = number of $20 bills.

f + t = 15

50f + 20t = 570

f = 15 - t

50(15 - t) + 20t = 570

750 - 50t + 20t = 570

-30t = -180

t = 6

f + t = 15

f + 6 = 15

f = 9

The line of reflection and the image of after reflection graph is attached below  

What is line of reflection ?

The picture is consistent with the preimage when reflecting a figure in a line or a point. Every point on a figure is translated into an image by a reflection across a set line. The term "line of reflection" refers to the fixed line.

The line of reflection is a line across which an image will reflect. Every point in a figure is said to reflect the other figure if and only if it is equally spaced from every corresponding point in the other figure. The image that is reflected should be identical in size and shape but face the opposite way.

Graph the quadrilateral. By inspection, you can tell where the midpoint is. (see attachment 1)

Now, I'll draw a line through it. (see attachment 2)

To reflect across a line, think about the points traveling across the line the same number of spaces the point is from the line. For example, point A is three away from the line. So, A' will be 3 away from the other side. The coordinates will be at (-3,2). (see attachment 3).

Do the same for the other points, and you'll have your image.

The equation of the line is y = -3x + 2.

What is the slope of a line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are represented by Δy and Δx, respectively.

As a result, m = change in y/change in x = Δy/Δx is the formula for the change in y-coordinate with respect to the change in x-coordinate.

where "m" represents a line's slope.

Given that, the line passes through the point (-1,5) with slope of -3.

The equation of line passes through (x₁, y₁) with slope m is

y -  y₁ = m(x - x₁)

Putting x₁ = -1, y₁ = 5 and m = -3.

y - 5 = -3(x - (-1))

y - 5 = -3x - 3

and its actually really simple

when you want to find the y-intercept

set x to 0

it will look something like

A(0)+By=C

By=C

y=C/B

It makes more sense with actual numbers

so

3x+2y=4

3(0)+2y=4

0+2y=4

2y=4

y=2

therefore the y intercept would be 2

The range of the function f(x) = |x| + 7 is given by the option presented as follows:

7 ≤ y < ∞.

The range is composed by the set containing all the values assumed by the output of the function, that is, all the numeric values assumed by the function.

In the context of this problem, the function is defined as follows:

f(x) = |x| + 7.

The parent function is the absolute value function g(x) = |x|, which gives the distance of a point x from the origin, assuming real values of at least 0, as a distance cannot be negative.

The addition by 7 means that the parent function was translated up seven units, meaning that the minimum value assumed by the range is seven, and the range of the function is given by the last option given as follows:

Answer:

2 < x < 26

Step-by-step explanation:

The length of the side of a triangle must be less than the sum of the lengths of the other two sides of a triangle.
Therefore:

12+14>x

x<26

However, the following must also be true:

x+12>14 (The sum of x and 14 will always be greater than 12 because 14>12, so we don’t need to include that in the inequality)

So, x>2.
This means that the answer is 2<x<26

The relationship represented is linear. Where f(0) = 2 and f(n) = f(n-1)+4.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph. The graph of a linear function is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively. There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation.

Given,

Area of the walk that goea around the rectangular yard is 680 sq. ft.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

The rectangle's characteristics are listed below:

Dimension of the yard is

width = 40 ft

length = 53ft

Dimension of the yard without the walkway is

Width =40 - 4*2 = 40 - 8 = 32 ft

Length = 53 - 4*2 = 53 - 8 = 45 ft

Area of the yard = Width * Length = 40 * 53 = 2120 sq. ft

Area of the yard wtihout the walk = 32 * 45 = 1440 sq. ft

Therefore the area of the walk is = Area of yard - Area of yard without walk = 2120 = 1440 = 680 sq. ft.

Random sampling methods of assigning probabilities is used when we are dealing with sampling.

Random sampling is a method of assigning probabilities used when dealing with samples of a population. It involves randomly selecting a sample from the population and then using that sample to estimate the probabilities of different outcomes. This is done by calculating the proportion of the sample that falls into each category. For example, if you are trying to determine the probability of a certain outcome, you would randomly select a sample from the population and then count how many of the individuals in the sample fall into that category. The probability of the outcome would then be calculated by dividing the number of individuals in that category by the total number of individuals in the sample.
