The distance d between the student and the mirror is given by the similar triangles are d = 10.5 feet

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the triangles be represented as ΔABC and ΔCDE

Now , they are similar triangles

The measure of AB = height of the school = 30 feet

The measure of BC = distance from the school to the mirror = 50 feet

And ,

The measure of DE = height of the student = 6.3 feet

The measure of CD = distance d between the student and the mirror

So , the corresponding sides of similar triangles are in the same ratio

On simplifying the equation , we get

BC / AB = CD / DE

And , 50 / 30 = d / 6.3

Multiply by 6.3 on both sides , we get

d = ( 5/3 ) x 6.3

Answer: 28, 30, 32

Step-by-step explanation: The first integer is 28, the second is 30, and the third is 32. The difference from the first integer and the last integer should be 4. x is the first integer, so the equation is:

x+x+2+x+4=90

The first integer plus the second integer(x+2) plus the third integer(x+4) equals 90. Now solve.

x+x+2+x+4=90

3x+6=90

    -6  -6

3x=84

/3   /3

x=28

So the first integer is 28, second is 30, third is 32.

The amount of white paint did she use to paint her bedroom walls is 6 21/40 or 6.525 pints.

To find the amount of white paint used, we first need to find the amount of blue paint used. Since 1/4 of the total amount of paint is blue, we can multiply the total amount of paint by its fraction, 1/4, to find the amount of blue paint:
Blue paint = 8.7 pints × 1/4 = 87/40 = 2.175 pints

Now, to find the amount of white paint used, we can subtract the amount of blue paint from the total amount of paint:
White paint = 8.7 pints - 2.175 pints = 261/40 = 6.525 pints

So, Araceli used 6.525 pints of white paint to paint her bedroom walls.

In fraction form, this can be written as 6525/1000 pints, or 6 21/40 pints.

In decimal form, it is simply 6.525 pints.

Answer:

Step-by-step explanation:

A binomial distribution table is a table that lists the probabilities of obtaining a specific number of success outcomes in a fixed number of independent trials, given a constant probability of success in each trial. The binomial distribution is a discrete probability distribution that describes the number of success outcomes in a fixed number of independent trials with a binary outcome (success or failure).

The table lists the probabilities of obtaining k successes in n trials, where k is a non-negative integer and n is a positive integer. The probabilities are calculated using the binomial formula, which is given by:

P(k successes in n trials) = (n choose k) * p^k * (1 - p)^(n-k)

where (n choose k) is the number of ways to choose k success outcomes from n trials, p is the probability of success in each trial, and (1 - p) is the probability of failure in each trial.

Binomial distribution tables are useful for solving problems related to counting and probability, especially in situations where the number of trials is fixed and the probability of success is constant. They can also be used for hypothesis testing, calculating confidence intervals, and estimating population proportions in statistical applications.

Answer: A monomial representation is a way to express a polynomial as a product of powers of its variables, where each power is a non-negative integer. For example, the polynomial 2x^3 + 4x^2 - 6x + 8 can be represented as a monomial representation of (2x^3)(x^2)(-6x)(8).

Symmetric polynomials are polynomials that are invariant under permutation of their variables. A symmetric presentation is a way of expressing a symmetric polynomial as a sum of elementary symmetric polynomials, which are defined as the sum of all possible products of variables taken i at a time, where i ranges from 1 to the number of variables. For example, the symmetric polynomial x^3 + y^3 + z^3 can be expressed as a symmetric presentation of x + y + z.

The probability that Justen wins is 4/9.

The probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.

The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.

However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.

This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.

The probability of each of these scenarios is (1/3) * (2/3) = 2/9.

So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.

Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.

Therefore, the probability that Justen wins is 4/9.

The time it takes is 2 seconds

To find the time that the balloons collided at the highest point, we need to find the vertex of the resulting quadratic function.

First, we can set the two functions equal to each other, since they represent the height of the two balloons at any given time:

-7x^2 + 26x + 3 = -6x^2 + 23x + 5

Simplifying and rearranging terms, we get:

-x^2 + 3x + 2 = 0

Now, we can use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -1, b = 3, and c = 2.

Plugging in these values, we get:

x = (-3 ± sqrt(3^2 - 4(-1)(2))) / 2(-1)

x = (-3 ± sqrt(1)) / (-2)

Simplifying further, we get:

x = (-3 ± 1) / (-2)

So, x can be either 1 or 2. However, we're only interested in the positive value for x since time cannot be negative.

Therefore, the time that the balloons collided at the highest point is:

x = 2 second
