Give measures for a, b , and an acute c. two triangles.

20 balloons in 7.34 minutes? lets do the math! \(\frac{20}{7.34\\}\) = 2.73 balloons a minute.

If Trevon took 14.1 minutes, lets do the math, \(\frac{20}{14.1}\) = 1.42 balloons a minute, now if we take 2.73, subtract 1.42 from 2.73. 2.73 - 1.42, we get, Drum roll please...................... 1.31 !!! So, with that fact, we get 1.31, so that means Mary would have to blow 1.31 balloons a minute WITH Trevon, now some more math. we take the amount Mary did, 1.31, and the amount of time it took for both, 7.34, we get this problem, 1.31 x 7.34 which equals (yes I'm doing it again) DRUM ROLL PLEASEEEE....................... 9.60!!!!!!!!

So, in the end, the answer is 9.60

James has written a correct if-then statement.

In an if-then statement the part following the "if" should be a hypothesis, and the part following the "then" should be a conclusion statement.

Considering the two of the given statements:

Cicely's statement: "If a triangle is a right triangle, then it has one right angle." is correct since the hypothesis and conclusion are both correct.

James's statement: "If a triangle has one right angle, then it is a right triangle." is also correct since the hypothesis and conclusion are both correct.

Now, comparing both the statements "If a triangle has one right angle" is a perfect hypothesis since it gives a condition which when followed gives the conclusion.

Hence, James has written a correct if-then statement.

Step-by-step explanation:

In order to plot points H I and J on the coordinate planeIdentify the x-coordinate and y-coordinate of each point (H, I, and J). For example, let's say the coordinates are as follows:

Point H: (xH, yH)

Point I: (xI, yI)

Point J: (xJ, yJ)

Locate the origin (0, 0) on the coordinate plane. This is the starting point for plotting any point.

Move along the x-axis according to the x-coordinate of each point. If the x-coordinate is positive, move to the right; if it's negative, move to the left. Mark a point on the x-axis at the appropriate location.

Move along the y-axis according to the y-coordinate of each point. If the y-coordinate is positive, move upward; if it's negative, move downward. Mark a point on the y-axis at the appropriate location.

The point where the x and y axes intersect is the location of the point. Mark that point on the coordinate plane.

How to Plot points H I and J on the coordinate plane

To find the area of a quadrilateral with given coordinates, you can use the Shoelace Formula.

The Shoelace Formula, also known as Gauss's area formula, provides a method to calculate the area of any polygon given its coordinates. Here's how it works for a quadrilateral:

Let's say you have the coordinates of the four vertices of the quadrilateral: (x1, y1), (x2, y2), (x3, y3), and (x4, y4).

1. Write down the coordinates in a clockwise order:

  (x1, y1), (x2, y2), (x3, y3), (x4, y4), (x1, y1).

2. Multiply each x-coordinate by the y-coordinate of the next vertex.

  For example, for the first vertex (x1, y1), multiply x1 by y2, and for the second vertex (x2, y2), multiply x2 by y3, and so on.

3. Multiply each y-coordinate by the x-coordinate of the next vertex.

  For example, for the first vertex (x1, y1), multiply y1 by x2, and for the second vertex (x2, y2), multiply y2 by x3, and so on.

4. Add up all the results from Steps 2 and 3.

5. Take the absolute value of the sum calculated in Step 4 and divide it by 2.

By following the steps of the Shoelace Formula, you can calculate the area of a quadrilateral given its coordinates. Remember to ensure that the coordinates are listed in a clockwise or counterclockwise order to obtain the correct result. This method can be applied to any quadrilateral shape and provides an efficient way to find its area without requiring complex calculations or trigonometric functions.

The length of side a is 10/3, and the length of the hypotenuse c is 2√(34)/3.

To find the length of side a, we can use the tangent of angle A. The tangent of an angle is equal to the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. In this case, tan(A) = 5/12, which means that the length of side a is 5/12 times the length of the adjacent side. Since we know that side b is 2, we can calculate a = \((5/12) * 2 = 10/3\).

To find the length of the hypotenuse c, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, we know that side b is 2 and side a is 10/3. Let's denote the length of c as x. Applying the Pythagorean theorem, we have \((10/3)^2 + 2^2 = x^2\). Simplifying this equation, we get \(100/9 + 4 = x^2\). Combining the terms, we have 100/9 + 36/9 = \(x^2\), which gives us \(136/9 = x^2\). Taking the square root of both sides, we have \(x = \sqrt{(136/9)} = \sqrt{(136)/} \sqrt{(9)} = \sqrt{(136)/3} = 2\sqrt{(34)/3}\).

Therefore, the lengths of the missing sides are a = 10/3 and c = \(2 \sqrt{(34)/3}\).

If the town has a population of 20000 and grows at 5% every year , then the time required for the population to reach 41600 is 15 years .

To find out how long it will take for the town's population to reach 41600, we can use the formula :

⇒ A = P(1 + r)ⁿ

Where:

A = final population of town , P = initial population o town

r = percent increase (as a decimal)

let n = number of years for population to reach 41600 .

We know the final population is 41600, the initial population is 20000, the percent increase is 5% = 0.05  and we have to solve for n.

Substituting the values ,

we get ;

⇒ 41600 = 20000(1 + 0.05)ⁿ  ;

⇒ 41600 = 20000(1.05)ⁿ  ;

⇒ 41600/20000 = (1.05)ⁿ  ;

taking "log" on both sides ,

we get ;

⇒ log(41600/20000) = n × log(1.05)  ;

⇒ n = log(41600/20000)/log(1.05)  ;

⇒ n = 15.0105 ≈ 15

Therefore ,  it will take approximately 15 years for the town's population to reach 41600, to the nearest tenth of a year.

An angle in a rectangular coordinate system is in standard position if its vertex is at the origin of the plane, the initial side of the angle is on the positive x-axis, and the terminal side of the angle is in one of the four quadrants. The angle is measured in a counterclockwise direction from the positive x-axis and is considered positive if it lies in the counterclockwise direction and negative if it lies in the clockwise direction.

The position of an angle is measured from the reference line called the initial side, which is the positive x-axis, and it ends at the terminal side, which is the side where the angle is located. An angle in a rectangular coordinate system is in a standard position if its vertex is at the origin of the plane.

The first four nonzero terms of the Taylor series about 0 for the function f(t) = t^2 sin(5t) are:

t^2, (5/3)t^3, ...

To find the first four nonzero terms of the Taylor series about 0 for the function f(t) = t^2 sin(5t), we need to compute the derivatives of f(t) at t = 0 and evaluate them at t = 0.

The first few derivatives of f(t) are:

f'(t) = 2t sin(5t) + t^2 * 5cos(5t)

f''(t) = 2 sin(5t) + 2t * 5cos(5t) + (2t)^2 * (-25sin(5t))

f'''(t) = 10cos(5t) + 10t * (-25sin(5t)) + (2t)^2 * (-125cos(5t)) + (2t)^3 * 125sin(5t)

Evaluating these derivatives at t = 0, we have:

f(0) = 0

f'(0) = 0

f''(0) = 2

f'''(0) = 10

Now, let's write the Taylor series using these derivatives:

f(t) ≈ f(0) + f'(0)t + f''(0)t^2/2! + f'''(0)t^3/3! + ...

Substituting the values we obtained, we get:

f(t) ≈ 0 + 0 + 2t^2/2! + 10t^3/3! + ...

The graph of the line parallel to x-axis and passes trough the point (-2,3).

What is 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 denoted by Δy and Δx, respectively.

Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is

m = Δy/Δx  = change in y/change in x

where "m" represents a line's slope.

Additionally, the slope of the line can be shown as

tan θ = Δy/Δx.

Given that the slope of the line is 0. Thus the angle between the line with the x-axis is 0 degree as tan 0° = 0.

The line is parallels to x-axis.

The equation of the line that is parallel to x-axis is y = a.

Since the line passes through the point (-2,3), thus it will be satisfies the equation line.

Putting x = -2 and y = 3

(a) the expected value of the amount you win 2/9 , (b) the variance of the amount you win 5/18 , c) The expected value of the amount you win is -$0.0667 and d)The variance of the amount you win is 1.2898.

Let's calculate the expected value and variance of the amount you win step by step:

a) Calculate the probability of drawing two marbles of the same color.

First, calculate the probability of drawing two red marbles:

P(RR) = (5/10) * (4/9) = 20/90 = 2/9

Similarly, calculate the probability of drawing two blue marbles:

P(BB) = (5/10) * (4/9) = 20/90 = 2/9

b) Calculate the probability of drawing two marbles of different colors.

P(RB) = (5/10) * (5/9) = 25/90 = 5/18

P(BR) = (5/10) * (5/9) = 25/90 = 5/18

c) Calculate the expected value.

The expected value (EV) is calculated by multiplying each outcome by its probability and summing them up.

EV = (P(RR) * $1.10) + (P(RB) * -$1.00) + (P(BR) * -$1.00) + (P(BB) * $1.10)

= (2/9 * $1.10) + (5/18 * -$1.00) + (5/18 * -$1.00) + (2/9 * $1.10)

= $0.2444 - $0.2778 - $0.2778 + $0.2444

= -$0.0667

Therefore, the expected value of the amount you win is -$0.0667.

d) Calculate the variance.

The variance is a measure of the dispersion of the outcomes around the expected value. It is calculated as the sum of the squared differences between each outcome and the expected value, weighted by their probabilities.

Variance = (P(RR) * ($1.10 - EV)²) + (P(RB) * (-$1.00 - EV)²) + (P(BR) * (-$1.00 - EV)²) + (P(BB) * ($1.10 - EV)²)

Variance = (2/9 * ($1.10 - (-$0.0667))²) + (5/18 * (-$1.00 - (-$0.0667))²) + (5/18 * (-$1.00 - (-$0.0667))²) + (2/9 * ($1.10 - (-$0.0667))²)

= (2/9 * $1.1667²) + (5/18 * -$0.9333²) + (5/18 * -$0.9333²) + (2/9 * $1.1667²)

= 1.2898

There are in total 5 sides because one of the sides is not shown on the surface level.

Upper base = 3 × 3 = 9 cm²

4 sides = 3 × 8 × 4 = 96 cm²

Total = 9 + 96 = 105 cm²

STEP TWO: Find the surface area of the larger rectangle (orange)

There are in total 5 whole sides with one side covered by the base of the smaller rectangle (green) which should later be subtracted.

Front and back = 7 × 10 × 2 = 140 cm²

Left and right = 7 × 12 × 2 = 168 cm²

Lower base = 10 × 12 = 120 cm²

Upper base = 10 × 12 - 3 × 3 = 111 cm²

Total = 140 + 168 + 120 + 111 = 539 cm²
