Sebastian has
x nickels and
y pennies. He has at least 20 coins worth at most $0.65 combined. Solve this system of inequalities graphically and determine one possible solution.

Answer:

g(-5) = 8(-5) - 24 = -40 - 24 = -64

g(5) = 8(5) - 24 = 40 - 24 = 16

y = 8x - 24

8x = y + 24

x = (1/8)(y + 24) = (1/8)y + 3

g^-1(x) = (1/8)x + 3, -64 < x < 16

The given diagram implies that the triangle $ABC$ is an isosceles triangle with angles of $24^\circ$. This can be verified by computing the length of the hypotenuse and using the Pythagorean Theorem.

Equation is a mathematical expression that consists of variables, symbols, and numbers, and shows the relationship between different quantities. An equation can involve one or more unknowns, and can be represented as an equality or as an inequality. Solving an equation requires understanding the relationship between the different elements in the equation, and manipulating the equation to isolate the unknowns. Common types of equations include linear equations, quadratic equations, and polynomial equations.

From this diagram, we can conclude that $\angle ABC$ is an isosceles triangle. This is because the angles opposite equal sides of a triangle must be equal. Since $\angle BAC=24^\circ$, $\angle ABC$ must be $24^\circ$. Furthermore, the sides $AB$ and $AC$ are equal, so $ABC$ is an isosceles triangle.

This conclusion can be verified by using the Pythagorean Theorem. If $AB=AC$, then it follows that $BC = \sqrt{AB^2 + AC^2} = \sqrt{2AB^2}$. Since $AB=3$, it follows that $BC=\sqrt{2*3^2}=6$. Therefore, the triangle $ABC$ is a right triangle with legs of length 3 and hypotenuse of length 6. Since $\angle BAC = 24^\circ$, it follows that $\angle ABC = 24^\circ$, verifying that the triangle is isosceles.

In conclusion, the given diagram implies that the triangle $ABC$ is an isosceles triangle with angles of $24^\circ$. This can be verified by computing the length of the hypotenuse and using the Pythagorean Theorem.

Answer:

78

Step-by-step explanation:

The maximum volume of the box is approximately 128.0in³.

Since the cardboard has dimensions of 8 inches by 12 inches, the largest possible length and width of the box are both 8 inches (since 8 is the smaller of the two dimensions).

Then we can cut two 8-inch by 8-inch squares from the cardboard to make the top and bottom of the box, and then cut out four 8-inch by 2-inch rectangles from the remaining cardboard to make the sides of the box.

The height of the box will be the same as the width of the 8-inch by 2-inch rectangles, which is 2 inches. Therefore, the maximum volume of the box is:

We can do this using the following formula:scale = distance on map ÷ distance on groundFirst, we need to convert the dimensions of Kansas from miles to inches using a common scale factor. Since 1 mile is equal to 63,360 inches, we have:Length of Kansas: 410 miles × 63,360 inches/mile = 25,984,600 inchesWidth of Kansas: 210 miles × 63,360 inches/mile = 13,315,200 inchesNow we can calculate the possible scales of the map based on the dimensions of the page in Jada's book, which is 5 inches by 8 inches:For the length of Kansas:scale = 5 inches ÷ (25,984,600 inches ÷ 2.54 cm/in) = 0.0000484scale = 8 inches ÷ (25,984,600 inches ÷ 2.54 cm/in) = 0.0000774For the width of Kansas:scale = 5 inches ÷ (13,315,200 inches ÷ 2.54 cm/in) = 0.0000962scale = 8 inches ÷ (13,315,200 inches ÷ 2.54 cm/in) = 0.0001539Therefore, the possible scales of the map are 1:20,655, and 1:10,326.

The magnitude of the car's acceleration when s=100m and x=0 is 3.49 [tex]m/s^2[/tex] evaluated using the kinematic equation of motion.

We can use the kinematic equation of motion to determine the acceleration of the car at the given distance:

[tex]s = ut + (1/2)at^2[/tex]

where s=distance traveled, u = initial velocity, a =acceleration, and t =

time taken.

We can rewrite this equation as:

[tex]t = (2s/u)^(1/2)[/tex]

Substituting the given values, we get:

[tex]t = (2(100)/20)^(1/2)[/tex] = 2.236 seconds

Now, we can use the kinematic equation:

v = u + at

where v is the final velocity.

We know the initial velocity u is 20 m/s, and the car's acceleration At=0.5 [tex]m/s^2[/tex]. To find the final velocity, we can use the kinematic equation again:

[tex]s = ut + (1/2)at^2 + vt[/tex]

Rearranging and substituting the given values, we get:

[tex]v = (s - ut - (1/2)at^2) / t[/tex]

v = (100 - (20)(2.236) - (1/2)(0.5)(2.236)^2) / 2.236

v = 27.839 m/s

Now we can evaluate the acceleration using the equation:

a = (v-u) / t

Substituting the given values, we get:

a = (27.839 - 20) / 2.236

a = 3.49[tex]m/s^2[/tex] (rounded to two decimal places)

Therefore, the magnitude of the car's acceleration when s=100m and x=0 is 3.49 [tex]m/s^2.[/tex]

The correct postulate that states a line is determined by two points is:

• Postulate 2: Through any two different points, exactly one line exists.

Postulate 2 states that if you have two distinct points, you can uniquely determine a line that passes through both of them. In other words, any two points in space define a line, and there is only one line that can pass through those two points.

This postulate is a fundamental concept in Euclidean geometry, which is the study of geometry based on the work of the ancient Greek mathematician Euclid.

This postulate is often used as a basic assumption or starting point in geometric proofs and constructions. It implies that a line is uniquely defined by just two points, and any additional points on that line can be determined by extending it infinitely in both directions.

It also implies that two distinct points always lie on exactly one line, and no more than one line can pass through them.

Postulate 2 is a fundamental principle in geometry and serves as the basis for many geometric theorems and proofs.

It helps establish the relationship between points and lines in Euclidean space, and it is used to reason about the properties and behavior of lines and points in geometric constructions, proofs, and demonstrations.

Step-by-step explanation:

50 miles would make the two choices equivalent in cost.

The following formula is used to determine a line's slope:

slope is equal to y2 - y1 / x2 - x1.

where the two points on the line are (x1, y1) and (x2, y2). The steepness or rate of change of the line is indicated by the slope. A line with a positive slope is increasing from left to right, whereas a line with a negative slope is dropping from left to right. An undefined slope denotes a vertical line, while a slope of zero denotes a horizontal line.

To determine the choice where the two miles are equivalent we take x as the number of miles:

For the first company:

Total cost = 25 + 0.8x

For the second company:

Total cost = 35 + 0.6x

Setting the equations as equal:

25 + 0.8x = 35 + 0.6x

0.2x = 10

x = 50

In mathematics, a variable is a symbol or letter that designates a value of the variable or amount. Variables are fundamental to many fields of science, technology, and mathematics and are used to formulate and solve equations.

Let's use constants to depict Jimmy's discovery of nickels and dimes.

Let x be the quantity of nickels and y be the quantity of dimes.

We may create the following pair of equations using the data:

Formula 1: x + y = 31 

Equation 2 reads: 0.05x + 0.10y = 2.35, which equals the total worth of the coins at $2.35.

The methods of substitution and elimination can be used to calculate the characteristics of x and y. Substitutions made

Equation 1 might be used to convert this x into units of y: x = 31 - y

In Equation 2, replace x with the following expression: 0.05(31 - y) + 0.10y = 2.35

Simplify the equation and find y as follows: 1.55 - 0.05y + 0.10y = 2.35 0.05y = 0.80 y = 16

What is linear equation?

A linear equation is a mathematical equation that describes a straight line in a two-dimensional plane. It is an equation of the form:

y = mx + b

Let's assume that Jimmy found x number of nickels and y number of dimes. Then we can write two equations based on the given information:

The total number of coins is 31:

x + y = 31

The total value of the coins is $2.35:

0.05x + 0.10y = 2.35

To solve for x and y, we can use the first equation to solve for x in terms of y:

x = 31 - y

Then we can substitute this expression for x into the second equation:

0.05(31 - y) + 0.10y = 2.35

1.55 - 0.05y + 0.10y = 2.35

0.05y = 0.80

y = 16

So Jimmy found 16 dimes. To find the number of nickels, we can substitute this value of y into either of the two equations we started with. Let's use the first equation:

The area of ​​the triangular pyramid is 787.27 mm²

The volume of a right-angled triangular pyramid  is given by the formula V = 1 3 × B × h, where B is the area of ​​the base of the triangle and h is the height (the distance from the apex to the base).

 To calculate the  area of ​​a triangular pyramid, we need to find the area and base of the four triangles.

First, we find the area of ​​the base of an equilateral triangle. The formula for the area of ​​an equilateral triangle is (sqrt(3)/4)*a², where a is the side length. Substituting a=19, we get:

Area of ​​base = (√(3)/4)*19²

= 207.39 mm²

Then we find the area of ​​one triangular surface. We can use the formula for the area of ​​a triangle, which is (1/2) the height of the base. The base of the triangle is the other side of an equilateral triangle with a length of 19 mm. The height of the triangle is the  height of the diagonal of the pyramid, which is 17 mm. Using the Pythagorean theorem, we can find the length of the height of the triangle:

h = √ (slope² - (1/2 base)²)

= √(17² - (1/219)²)

= 15.27 mm

Thus, the area of ​​one triangular surface is:

Area of ​​triangle = (1/2)1915.27

= 144.97 mm²

Since there are four triangular faces, the total area of ​​the triangular faces is:

Total area of ​​triangular surfaces = 4 × 144.97

= 579.88 mm²

Finally, the  area of ​​the pyramid is the sum of the area of ​​the base and the area of ​​the four triangular sides:

Area = area  of ​​base Total area of ​​triangular surfaces

= 207.39 + 579.88

= 787.27 mm²

Therefore the  area of ​​the triangular pyramid is 787.27 square millimeters.
