Lets say:

1st choice vote: 4 points

2nd choice vote: 2 points

Thus by the use of these point values, the turtle would have the next chance of winning since 1st choice votes would be worth more point (4 point ) compared to 2nd choice votes (3 point ). This would push individuals to select the turtle as their 1st choice, because it would allow the turtle a better add up to point gains and increase its chances of winning.

Given:

Kianas soccer teams ratio of wins to losses is 5:3.

Her team has played 24 games.

To find:

The number of games they won.

Solution:

Let the number of games they won be 5x and the number of games they lost be 3x.

Total number of games is 24.

\(5x+3x=24\)

\(8x=24\)

\(x=\dfrac{24}{8}\)

\(x=3\)

Now, the number of games they won is:

Number of games they won = \(5x\)

                                               = \(5(3)\)

                                               = \(15\)

Answer:

The solution is 10/9

Step-by-step explanation:

Step 1: identify the right approach:

Given a function g(x) over a period of time, to find the average rate of change of g(x) over this period of time, we divide the change in g(x) by the change in x.

Step 2: Perform the calculation:

As shown in picture,

so the solution is:

If four-fifths of a liter of lemonade was poured into 5 cups so that each cup had the same amount, each cup would contain 1/5 of four-fifths of a liter.

1/5 of four-fifths can be calculated as follows:

(1/5) * (4/5) = 4/25

So, each cup contains 4/25 of a liter of lemonade.

If the lemonade from 4 of those cups was poured into one large glass, the large glass would contain the combined amount from those 4 cups. Therefore, the large glass would contain:

4 * (4/25) = 16/25

Thus, the fraction of a liter of lemonade in the large glass is 16/25.

To find the volume of the largest rectangular box that can be inscribed in the given ellipsoid, we need to find the dimensions of the box that maximize its volume. The box is aligned with the axes, so its edges are parallel to the coordinate axes.

The general equation of an ellipsoid centered at the origin is (x^2/a^2) + (y^2/b^2) + (z^2/c^2) = 1, where a, b, and c are the semi-major axes of the ellipsoid along the x, y, and z axes, respectively. Comparing this equation to the given ellipsoid, we have a = 2, b = 8, and c = 7. These values represent the distances from the center to the ellipsoid's surface along the respective axes. For a rectangular box inscribed in the ellipsoid, the dimensions of the box will be twice the semi-major axes of the ellipsoid. Therefore, the dimensions of the box will be 2a, 2b, and 2c. Hence, the volume of the largest rectangular box inscribed in the ellipsoid is (2a) * (2b) * (2c) = 2 * 2 * 2 * a * b * c = 8 * 16 * 14 = 1792. Therefore, the volume of the largest rectangular box that can be inscribed in the given ellipsoid is 1792 cubic units.

The dimensions that will result in a solid with maximum volume are approximately x = 12.02 centimeters and h = 5.01 centimeters.

Let the side of the square base be x, and let the height of the rectangular solid be h. Then, the surface area of the solid is given by:

Surface area = area of base + area of front + area of back + area of left + area of right

Surface area = x² + 2xh + 2xh + 2xh + 2xh = x² + 8xh

We are given that the surface area is 433.5 square centimeters, so we can write: x² + 8xh = 433.5

We want to find the dimensions that will result in a solid with maximum volume. The volume of the solid is given by:

Volume = area of base × height = x² × h

We can use the surface area equation to solve for h in terms of x:

x² + 8xh = 433.5

h = (433.5 - x²)/(8x)

Substituting this expression for h into the volume equation, we get:

Volume = x² × (433.5 - x²)/(8x) = (433.5x - x³)/8

To find the maximum volume, we need to find the value of x that maximizes this expression. To do this, we can take the derivative of the expression with respect to x, set it equal to zero, and solve for x:

d(Volume)/dx = (433.5 - 3x²)/8 = 0

433.5 - 3x² = 0

x² = 144.5

x = sqrt(144.5) ≈ 12.02

We can check that this is a maximum by computing the second derivative of the volume expression with respect to x:

d²(Volume)/dx² = -3x/4

At x = sqrt(144.5), this is negative, which means that the volume is maximized at x = sqrt(144.5).

Substituting x = sqrt(144.5) into the expression for h, we get:

h = (433.5 - (sqrt(144.5))²)/(8×sqrt(144.5))

h = 433.5/(8×sqrt(144.5)) - sqrt(144.5)/8

h = 5.01

The dimensions of the rectangular solid that will result in a maximum volume are approximately.\(6.34 cm \times 9.03 cm \times 9.03 cm.\)

Let's assume that the length, width, and height of the rectangular solid are all equal to x, so the base of the solid is a square.

The surface area of the rectangular solid can be expressed as:

\(SA = 2xy + 2xz + 2yz\)

Substituting x for y and z, we get:

\(SA = 2x^2 + 4xy\)

We are given that the surface area is 433.5 square centimeters, so:

\(2x^2 + 4xy = 433.5\)

Simplifying, we get:

\(x^2 + 2xy - 216.75 = 0\)

Using the quadratic formula to solve for y, we get:

\(y = (-2x\± \sqrt (4x^2 + 4(216.75)))/2\)

\(y = -x \± \sqrt (x^2 + 216.75)\)

Since the base of the rectangular solid is a square, we know that y = z. So:

\(z = -x \± \sqrt(x^2 + 216.75)\)

The volume of the rectangular solid is given by:

\(V = x^2y\)

Substituting y for\(-x + \sqrt (x^2 + 216.75),\) we get:

\(V = x^2(-x + \sqrt(x^2 + 216.75))\)

Expanding and simplifying, we get:

\(V = -x^3 + x^2\sqrt(x^2 + 216.75)\)

The dimensions that will result in a solid with maximum volume, we need to find the value of x that maximizes the volume V.

We can do this by taking the derivative of V with respect to x, setting it equal to zero, and solving for x:

\(dV/dx = -3x^2 + 2x\sqrt(x^2 + 216.75) + x^2/(2\sqrt (x^2 + 216.75)) = 0\)

Multiplying both sides by \(2\sqrt (x^2 + 216.75)\) to eliminate the denominator, we get:

\(-6x^2\sqrt (x^2 + 216.75) + 4x(x^2 + 216.75) + x^3 = 0\)

Simplifying, we get:

\(x^3 - 6x^2\sqrt (x^2 + 216.75) + 4x(x^2 + 216.75) = 0\)

We can solve this equation numerically using a graphing calculator or computer software.

\(The solution is approximately x = 6.34 centimeters.\)

Substituting x = 6.34 into the expression for y and z, we get:

\(y = z \approx 9.03 centimeters\)

When you are deciding how much of something is needed to cover something, in this case a table, you need to know everything. Including the inner part of the circle. Not just the outside.

b. The measure of angle 1 is 90°.

c. The lines are perpendicular.

d. Angle 1 is a right angle.

Perpendicular lines are connected to right angles.

Right Angles

Right angles are 90° angles. Oftentimes, these angles are denoted by a square drawn near the vertex. As you can see in the image, angle one has a square drawn in the vertex, which shows that it is a right angle. This means it has a measure of 90°.

Right angles are not considered acute or obtuse. Instead, a right angle is its own category.

Perpendicular Lines

Perpendicular lines are lines that form right angles at the intersection. Since angle 1 is a right angle, the lines must be perpendicular. Additionally, when perpendicular meet, all 4 angles created are right angles. This means the other 3 angles shown are also right angles.

The discriminant of a quadratic equation is the expression b^2 - 4ac, where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c.

To determine whether each quadratic equation has two real solutions, a double root, or no real solution, we need to look at the value of the discriminant.

For the equation 2a^2 + 3a + 1 = 0, the discriminant is b^2 - 4ac = 3^2 - 4(2)(1) = 1. Since the discriminant is positive and not equal to zero, there are two real solutions.

For equation 2a(a – 3) – 3 = 3, we need to rearrange it into standard form first, which gives us 2a^2 - 6a - 6 = 0. The discriminant is b^2 - 4ac = (-6)^2 - 4(2)(-6) = 60. Since the discriminant is positive, there are two real solutions.

For the equation 3a^2 – 2a(a – 2)^2 – 4 = 0, we need to expand the squared term first, which gives us 3a^2 - 2a(a^2 - 4a + 4) - 4 = 0. Simplifying this equation gives us 3a^2 - 2a^3 + 8a - 4 = 0. The discriminant is b^2 - 4ac = 8^2 - 4(3)(-2) = 100. Since the discriminant is positive, there are two real solutions.

Therefore, all three quadratic equations have two real solutions.
