Answer:

The area of a rectangle is given by the product of its length and width. In this case, the length of the rectangle is -x + 18, and the width is x + 4. So, the area is:

Area = (length) x (width)

= (-x + 18) x (x + 4)

= -x^2 + 14x + 72

Therefore, the area of the rectangle is -x^2 + 14x + 72.

You should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

An expression is a group of symbols and/or numbers used to represent a quantity or a mathematical relationship between two quantities in mathematics. Variables, constants, as well as operators like addition, subtraction, multiplication, and division, can all be found in an expression.

Since there are 4 quarts in a gallon, 1.5 quarts is equal to 1.5/4 = 0.375 gallons of gasoline.

To determine how much oil to add, we need to use the ratio of 2.4 fl. oz. of oil for every gallon of gasoline.

First, we need to convert the amount of gasoline we have from gallons to fluid ounces:

0.375 gallons x 128 fluid ounces per gallon = 48 fluid ounces of gasoline.

Next, we can use the ratio to find how much oil to add:

2.4 fl. oz. oil: 1 gallon gasoline

x fl. oz. oil: 48 fl. oz. gasoline

Cross-multiplying, we get:

2.4 x 48 = 1 x (x)

115.2 = x

So you should add 115.2 fluid ounces of oil to your 1.5 quarts of gasoline.

The weekly growth rate of these gnats is approximately 1.38%.

With discrete growth, we may observe change taking place following a particular event. We receive fresh options when we flip a coin. We pay interest once a year. After a successful mating season, young are produced. Change occurs continuously in an economy that is growing. We are unable to remark, "It changed here," in reference to an occurrence. The pattern is always changing (radioactive decay, a bacteria colony, or perfectly compounded interest).

Given that,

G(t) = 500(1.182)t

Using the growth function for 52 weeks = 1 year we have:

= 500(1 + r)⁵²ˣ

where r is the weekly growth rate.

To find the weekly growth rate, we can first rewrite the equation as:

1 + r = (1.182)⁽¹⁾⁵²

1 + r = 1.0138

r = 0.0138

The equivalent equation using the weekly growth factor is:

The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³

Dilation is the increase or decrease in the size of a figure.

The cone has surface area 360π in² and volume 800π in^3. the cone is dilated, and the surface area of the dilated cone is 2,250π in^2.

Hence:

Scale factor² = dilated cone area / cone surface area

scale factor² = 2250π / 360π

Scale factor = 2.5

Volume of dilated cone = 2.5³ × 800π = 12500π in³

The inequality that represents possible values for the number of cupcakes purchased, c, and the number of brownies purchased, b is:

             (c+b) ≥ 15

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. However several inequalities are utilised to compare the numbers, whether it is less than or higher than. An inequality symbol has non-equal expressions on both sides. It indicates that the expression on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using inequality symbols.

It is given that the least number of cupcakes and brownies that Salma should buy is 15.

Let the number of cupcakes purchased be c and the number of brownies purchased, b.  

Then the total number of cupcakes and brownies is c + b

This sum should be greater than or equal to 15.

The percentage of students with quiz scores between 72 and 90 points would be 81.5%.

Standard deviations is a statistical measure of the spread of data points around the mean in a set of data. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. Standard deviations are used to measure the uncertainty of a statistic or the variability of a population or sample of observations.

This answer is correct because the data is being modeled using a normal distribution. This means that the quiz scores can be described as a bell-shaped curve, with the mean score of 78 points being the highest peak. The 68% of the data that lies within 1 standard deviation of the mean would be between 72 and 90 points, which is the range specified in the question, so the answer is 81.5%. This is because 68% of the data lies within 1 standard deviation of the mean and 13.5% of the data lies within the second standard deviation of the mean. The sum of these two figures (68% + 13.5%) is 81.5%. Therefore, the percentage of students with quiz scores between 72 and 90 points would be 81.5%.

y = √24²+32² = √1600 = 40

find base angle Ф on the right:

Ф = sin⁻¹(32/40) = 53.13

find other base angle (sum of interior angles of a Δ is 180):

180 - 90 - 53.13 = 36.87

now you can use the Law of Sines to find z, x:

40/sin36.87 = z/sin53.13 = (x+24)/sin90

z = 40(sin53.13)/sin36.87 = 53.33

sin36.87(x+24) = 40(sin90)

x+24 = 40/sin36.87 = 66.66

x = 66.67 - 24 = 42.67

double check the answers:

y² + z² = (x+24)²

40² + 53.33² = (42.67 + 24)²

1600 + 2892 = 4444

In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another.

To apply this technique, the quadratic function must be rewritten in vertex form as follows: f(x) = a(x-h)2 + k, where (h,k) is the vertex of the parabola.

The coefficient -3 from the first two terms is first removed by factoring: [tex]f(x) = -3(x^2 - 4x) + 15.[/tex]

After that, we finish the square enclosed in parenthesis by calculating (4/2)2 = 4:

The parabola is at (2, 27), and because the squared term's coefficient is negative, the parabola widens downward. Set f(x) = 0 and solve for x to discover the zeros: [tex]0 = -3(x-2)2 + 27 3(x-2)2 = 27 (x-2)2 = 9 x-2 = 9 x = 2 3[/tex]

What is median ?

The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, the median is helpful. The median is one of the simple to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the center of a sequence to determine its value.

To support this, we can also calculate the median and mode of the data set to see if they are close to the mean. The median is the middle value of the sorted data set, which is 8 in this case, and the mode is the most common value, which is also 7 and 8 in this data set. So, the mean, median, and mode are all relatively close to each other, indicating that the data is roughly symmetric around the center.

In the graph, the major axis is the horizontal axis, while the minor axis is the vertical axis.

An ellipse is a geometric shape that is a type of curve. In mathematics, an ellipse is defined as a set of points in a plane, such that the sum of the distances between any point on the curve and two fixed points is a constant which is known as foci.

To identify the major and minor axes of an ellipse, you can use both the graph and the equation of the ellipse.

Identify the major and minor axes using the graph: The major axis is the longest diameter of the ellipse, which passes through the center and touches the curve at two points called the vertices. The minor axis is the shortest diameter of the ellipse, which also passes through the center and touches the curve at two points called the co-vertices. On the graph, the major axis is the horizontal axis, while the minor axis is the vertical axis.

Identify the major and minor axes using the equation: The equation of an ellipse can be written in the standard form:

[tex]\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} = 1[/tex]

where the ellipse's center is (h, k), the semi-major axis' length is a, and the semi-minor axis' length is b. The semi-major axis is half the length of the major axis, while the semi-minor axis is half the length of the minor axis. Therefore, you can identify the major and minor axes by looking at the denominators of the terms that contain x and y in the equation. The larger denominator corresponds to the semi-major axis, while the smaller denominator corresponds to the semi-minor axis.

Answer:

the height of the trapezoid is 25 yards.

Step-by-step explanation:

The area of a trapezoid is given by the formula:

Area = (1/2) * (b1 + b2) * h

where b1 and b2 are the lengths of the parallel bases and h is the height of the trapezoid.

In this problem, we are given the area of the trapezoid (600 yd^2), as well as the lengths of the two parallel bases (25 yd and 23 yd). Let's use this information to find the height of the trapezoid.

We can start by rearranging the formula for the area to solve for the height:

h = (2 * Area) / (b1 + b2)

Substituting the given values, we get:

h = (2 * 600 yd^2) / (25 yd + 23 yd)

Simplifying, we get:

h = 1200 yd^2 / 48 yd

h = 25 yd

Therefore, the height of the trapezoid is 25 yards.
