Answer:

6

Step-by-step explanation:

6+30=36

6^2=36

Answer:

the positive number is equal to  6.

Step-by-step explanation:

from the question which says A positive number is 30 less than its square. Find the number.

let the number be "n"

and the square of the number = n²

So, we have  the expression to be

n = n²-30

n ²-30 -n =0

Re-arrange the equation

n²-n-30=0

the factors of -30 are 5 and -6

so we have

(n+5)(n-6)=0

n+5 =0

n = -5

or

n-6 =0

n = 6

therefore the number can either be -5 or 6.

note we are asked to find the positive number , so the positive number is 6

To find the ground miles from a point below the plane to the radar station given the distance and angle of depression, use trigonometry to calculate the ground distance, which is approximately 107.2 miles.

Explanation:

The number of ground miles from a point directly below the plane to the radar station can be found using trigonometry. Given the distance from the plane to the radar station (160 miles) and the angle of depression (34 degrees), we can use the tangent function.

Calculate the distance on the ground using the formula: Ground distance = 160 x tan(34°).

Ground distance = 160 x tan(34°) ≈  160 x 0.67 = 107.2 miles.

Answer:

(6+x)(6-x)

Step-by-step explanation:

Use the difference of squares formula: a^2-b^2=(a+b)(a-b)

Here, a is 6 and b is x, so you just substitute it into the formula

Final answer:

To factor the expression 36 - x², we recognize it as a difference of squares and use the identity a² - b² = (a + b)(a - b) to get (6 + x)(6 - x).

Explanation:

The question involves factoring the expression 36 - x^2 as the product of two binomials. To factor this expression, observe that it has the form of a difference of squares. The difference of squares can be factored using the identity a² - b² = (a + b)(a - b). In this case, a^2 is 36 and b² is x², where a is 6 and b is x. Therefore:

36 - x² = (6² - x²) = (6 + x)(6 - x)

This is the factored form of the given expression as the product of two binomials.

Answer:

Avg. monthly expenses are $1,481.83

Step-by-step explanation:

Just took the test :)

Chandra's average monthly expenses are calculated by adding her total annual expenses for each category and then dividing by 12, yielding an average monthly expense of $1,481.83.

To calculate Chandra's average monthly expenses, we first need to sum up all the expenses for each month and then divide by the total number of months (12).

Adding all these up gives us the total annual expense:

$852 (cell phone) + $12,300 (rent) + $300 (gym) + $300 (internet) + $850 (auto insurance) + $1,440 (gas) + $1,740 (food) = $17,782 total annual expense.

To find the average monthly expense, we divide by 12:

$17,782 / 12 months = $1,481.83

Therefore, Chandra's average monthly expenses are $1,481.83.

Answer: 0.84 as a fraction is 84/100

Greatest common factor is 4

Resulting fraction is 21/25

Addition of numerator and denominator of the resulting fraction is 46

Step-by-step explanation:

From the question, the sum of 0.8 and 0.04 is written as 0.8 + 0.04 = 0.84

Convert 0.84 to fraction = 84/100

The numerator and denominator in 84/100 are both positive integers.

The greatest common factor to the numerator and denominator is 4

Divide 84 by 4 = 21

Divide 100 by 4 = 25

Therefore, the resulting fraction is 21/25

Addition of 21 and 25 equals 46.

The functions which will form the composite function G(F(x)) = 3(x + 1) are  F(x) = x + 1 and G(x) = 3x.

Given is a composite function,

G(F(x)) = 3(x + 1)

We have to find the functions G(x) and F(x).

G(F(x)) means that F(x) is substituted instead of x in G(x).

Let G(x) = 3x and F(x) = x + 1

In the composite function G(F(x)), F(x) = x + 1 is substituted in place of x in G(x).

So,

G(F(x)) = 3(x + 1)

Thus, F(x) = x + 1 and G(x) = 3x

Answer:

(6, 2)

Step-by-step explanation:

Flipped is equivalent to mirrored, so on the other side of the y axis should be a mirrored point equally far from 0, which is -6 and the value for y should be the same: 2.

The coordinates (-6,2) when flipped on the y-axis become (6,2), as the process involves changing the sign of the x-coordinate while keeping the y-coordinate same.

The coordinates (-6,2) when flipped on the y-axis will become (-(-6),2), which makes it (6,2). To understand why, we can refer to the principle of reflection in mathematics. Reflection of a point about the y-axis implies changing the sign of the x-coordinate while keeping the y-coordinate same. Here, the x-coordinate is -6, and when we flip or reflect on the y-axis, it changes its sign. Therefore, -(-6) becomes +6. The y-coordinate remains the same. Hence, -6 2 flipped on the y axis becomes (6, 2).

Answer:

(52, 32 )

Step-by-step explanation:

Given the 2 equations

y = x - 20 → (1)

x + y = 84 → (2)

Substitute y = x - 20 into (2)

x + x - 20 = 84, that is

2x - 20 = 84 ( add 20 to both sides )

2x = 104 ( divide both sides by 2 )

x = 52

Substitute x = 52 into (1) for corresponding value of y

y = 52 - 20 = 32

Solution is (52, 32 )

Answer:

There were 27 apples.

Step-by-step explanation:

Set a ratio of bananas to apples like this:

bananas/apples = 2/3

Now you have 18 bananas. The number of apples is unknown, so use "a" for the number of apples.

bananas/apples = 18/a

The two ratios above are equal, so set them equal. That creates a proportion.

2/3 = 18/a

Now we solve for a by cross multiplying.

2a = 3 * 18

2a = 54

a = 27

Answer:

1. P(N) =  3/5

2. P(R) =  2/5

3. P(N and R) = 1/4

4. P(N or R) = 3/4

Step-by-step explanation:

1. Let's review the information given to us to answer the problem correctly:

Number of students in a high school senior class = 500

Number of students that regularly wear a necklace = 300

Number of students that regularly wear a ring = 200

Number of students that wear a necklace and a ring = 125

2. What is P(N), the probability that a senior wears a necklace?

Let's recall the formula of probability:

Probability = Number of favorable outcomes/Total of possible outcomes

Substituting with the real given values:

P(N) = 300/500 = 3/5 (Dividing by 100 numerator and denominator)

P(N) =  3/5

3. What is P(R), the probability that a senior wears a ring?

Substituting with the real given values:

P(R) = 200/500 = 2/5 (Dividing by 100 numerator and denominator)

P(R) =  2/5

4. What is P(N and R), the probability that a senior wears a necklace and a ring?

Substituting with the real given values:

P(N and R) = 125/500 = 1/4 (Dividing by 125 numerator and denominator)

P(N and R) = 1/4

5. What is P(N or R), the probability that a senior wears a necklace or a ring?

P(N or R) = P(N) + P(R) - P(N and R)

Substituting with the real given values:

P(N or R) = 3/5 + 2/5 - 1/4

P(N or R) = 5/5 - 1/4

P(N or R) = 1 - 1/4

P(N or R) = 3/4

The probabilities are:

P(N) = 0.6
P(R) = 0.4

P(N and R) = 0.25

P(N or R) = 0.75.

Let's solve the given probabilities step-by-step using the provided information.

Step 1: Calculate P(N)

The probability that a senior wears a necklace, P(N), is calculated by dividing the number of students wearing a necklace by the total number of students.

Step 2: Calculate P(R)

The probability that a senior wears a ring, P(R), is calculated similarly by dividing the number of students wearing a ring by the total number of students.

Step 3: Calculate P(N and R)

The probability that a senior wears both a necklace and a ring, P(N and R), is given directly in the problem.

Step 4: Calculate P(N or R)

The probability that a senior wears either a necklace or a ring is given by the formula:

t = 1.1 sec for first time and then in

t = 3.9 sec

Step-by-step explanation:

The function for the height of the circus performers is:

[tex]h(t) = -16t^{2} +80t +32[/tex]

                             where t is seconds after launch

                                        h is height in feet

For calculating after how many seconds is the performer at 100 feet above the ground, we must equal the equation to 100 and to find t:

Then,

[tex]100 = -16t^{2} +80t+32[/tex]

[tex]0 = -16t^{2}+80t -68[/tex]

[tex]t = \frac{-80\ \pm \\\sqrt{80^{2}-4(-16)(-68) } }{2(-16)}[/tex]

t = 3.9 sec

t = 1.1 sec
