The possible lengths for AC are any values greater than the square root of 51.2 (approximately 7.15 feet).

If triangle ABC is isosceles, then AC must be equal to BC. Let's call the length of AC "x".

Using the Pythagorean theorem, we can find the length of the diagonal line segment BD (which is also the height of the peaked roof):

BD^2 = AB^2 - (AC/2)^2

BD^2 = 8^2 - (x/2)^2

BD^2 = 64 - x^2/4

To ensure that the roof is peaked, we need BD to be less than x (otherwise, the roof would be flat). So we can set up an inequality:

BD < x

√(64 - x^2/4) < x

64 - x^2/4 < x^2

256 - x^2 < 4x^2

5x^2 > 256

x^2 > 51.2

x > √(51.2)

Therefore, the possible lengths for AC are any values greater than the square root of 51.2 (approximately 7.15 feet).

Step-by-step explanation:

The equivalent fractions for 3/10 and 1/7 using the least common denominator are 6/20 and 3/20. The least common denominator of 3/10 and 1/7 is 20, so the fractions must be multiplied by the same number to reach the denominator of 20. 3/10 multiplied by 2/2 is 6/20, and 1/7 multiplied by 3/3 is 3/20.

The cost of one dinner without any sides is $2, and the cost of 6 dinners without any sides is 6 times that amount, which is $12. Answer: $12.

An equation is a statement that asserts the equality of two expressions. Equations typically contain one or more variables, which are quantities that can take on different values. The goal of solving an equation is to find the values of the variables that make the equation true.Equations can take many different forms, but some common types include linear equations, quadratic equations, polynomial equations, and exponential equations.

An expression is a combination of numbers, variables, and mathematical operations that represents a value. Expressions can contain constants, variables, and operators, such as addition, subtraction, multiplication, and division.

In the given question,

There are different ways to approach this problem, but one possible method is to use ratios. Let's assume that the cost of a dinner without any sides is x dollars. Then, the cost of a dinner with salad is x plus some additional amount for the salad, which we don't know yet. Let's call this additional amount y dollars. Therefore, the cost of a dinner with salad is x + y dollars.

According to the problem, Russell can buy 6 dinners with salads for $114. This means that the total cost of 6 dinners with salads is $114. We can write this as an equation: 6(x + y) = 114

Simplifying this equation, we get: 6x + 6y = 114

Dividing both sides by 6, we obtain: x + y = 19

Now we need to find the cost of 6 dinners without any sides, which is 6 times the cost of a dinner without any sides. We already know that the cost of one dinner without any sides is x dollars, so the cost of 6 dinners without any sides is 6x dollars.

To find x, we can use the fact that x + y = 19, which we derived from the given information. We don't know y, but we can express it in terms of x by using the fraction of the salad price to the total price of a dinner with salad. From the long division, we have:

2x - 3

x + 1

This means that y is equal to the remainder of the division, which is -3/(x+1). Therefore, we have: y = -3/(x+1)

Now we can substitute this expression for y into the equation x + y = 19:

x - 3/(x+1) = 19

Multiplying both sides by x+1, we get: x(x+1) - 3 = 19(x+1)

Expanding the products and simplifying, we obtain a quadratic equation:

x^2 + 18x - 22 = 0

We can solve this equation by using the quadratic formula:

x = (-18 ± √(18^2 + 4122)) / (2*1)

x = (-18 ± √(400)) / 2

x = (-18 ± 20) / 2

x = -9 or x = 2

Since we are interested in the cost of a dinner without any sides, which should be a positive number, we discard the negative solution and take x = 2. Therefore, the cost of one dinner without any sides is $2, and the cost of 6 dinners without any sides is 6 times that amount, which is $12. Answer: $12.

The net worth of the landscaping company is given by:

$187.205.

How to calculate the net worth?

The net worth of a company or of a person is given by the sum of all assets of the person subtracted by the sum of all debts of the person.

In the context of this problem, the assets, and it's values, of the company are given as follows:

Owned Inventory: $48,760.

Cash: $126,790.

Savings account: $32,436.

Owned equipment: $20,700.

Accounts receivable: $15,640.

Property value: $225,678.

Hence the sum of the assets is given by:

Assets = 48760 + 126790 + 32426 + 20700 + 15640 + 225678 = $469,994.

The debts of the company, with it's values, are given as follows:

Small Business Loan: $76,400.

Building Mortgage: $189,429.

Other debt: $16,970.

Hence the sum of the debts is given by:

Debts = 76400 + 189429 + 16970 = $282,799.

Then the net worth of the company is:

Net worth = Assets - Debt = 469,994 - 282,799 = $187,205.

8 X 1 1/3 kg = 10 2/3 kg

Answer:

The given expression is:

p^2 + 4q^2 + 9 + 36 + pq + 3 + 4q + 6p

Rearranging the terms, we get:

p^2 + 6p + 4q^2 + pq + 4q + 48

Now, we can group the first three terms and the last three terms together as follows:

(p^2 + 6p + 9) + (4q^2 + pq + 4q + 39)

The first group can be factorized as a perfect square trinomial:

(p + 3)^2

The second group can be factorized by grouping the first two terms and the last two terms:

(pq + 4q) + (4q^2 + 39)

We can factor out q from the first two terms, and 4 from the last two terms:

q(p + 4) + 4( q^2 + 9)

Now, we can factor the second group as a sum of squares:

q(p + 4) + 4(q + 3)(q - 3)

Therefore, the fully factorized form of the expression is:

(p + 3)^2 + q(p + 4) + 4(q + 3)(q - 3) + 48

Note that this expression cannot be simplified further.

Step-by-step explanation:

This is a right triangle, so the point is C(-2, -2), so 2+4=6

The given quadratic equation is f(x) = x³ - 3x² + 2x-1. The two solutions to the equation are x = (3x + √(9x² + 4))/2x² and x = (3x - √(9x² + 4))/2x².

A quadratic equation is written in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

To solve this equation, we will use the quadratic formula.

The quadratic formula states that for a quadratic equation of the form ax² + bx + c = 0, the solutions are given by

x = [-b ± √(b² - 4ac)]/2a.

In this equation, a = x², b = -3x, and c = -1. Plugging these values into the formula, we get x = [3x ± √(9x² - 4(x²)(-1))]/2(x²). Simplifying this, we get

x = [3x ± √(9x² + 4)]/2x².

Now, we must solve for the two solutions. The first solution is x = (3x + √(9x² + 4))/2x². The second solution is

x = (3x - √(9x² + 4))/2x².

Therefore, the two solutions to the given equation are

x = (3x + √(9x² + 4))/2x² and

x = (3x - √(9x² + 4))/2x².

The wrapping paper used by Aaron is 9 and 2/3 feet of paper

To solve this problem, use the given information about how much wrapping paper is needed for each game and gaming console, and then multiplied by the number of games and consoles that Aaron wraps in one hour. For simple calculation convert mixed fractions into an improper fraction and solve the problem.

Here we have

Aaron wraps present in a store. In one hour, he wraps 8 games and one console.

From the given figure,

Each game takes 2/3 foot of wrapping paper

Each gaming console takes 4 1/3 feet of wrapping paper

From the data

Aaron wraps 8 games in 1 hour

The wrap is used for 8 games = 8 × [ 2/3 foot ] = 16/3 foot

He wraps one console.

The wrap used for 1 console = 4 1/3

Here 4 1/3 = 13/3  [ Converting mixed fraction to improper fraction ]

Hence,

Total amount of wrap used = 16/3 + 13/3

= [ 16 + 13]/3 = 29/3 = 9 2/3

Answer:

Step-by-step explanation:

To find the constant of proportionality, we can use the formula for a proportional relationship: y = kx, where y is the total cost, x is the number of songs, and k is the constant of proportionality.

Using the table, we can find two pairs of values for y and x:

When x = 6, y = $1.80

When x = 12, y = $3.60

We can set up a proportion:

y1 / x1 = y2 / x2

$1.80 / 6 = $3.60 / 12

Simplifying, we get:

$0.30 = $0.30

This tells us that the constant of proportionality is $0.30.

We can check this by using another pair of values:

When x = 20, y = $6

Using the formula y = kx, we get:

$6 = ($0.30)(20)

Simplifying, we get:

$6 = $6

This checks out, so we can be confident that the constant of proportionality is $0.30.

There are initially 150 pharaoh ants in Southeast Asia, and every year the population increases by 950,000 ants.

The rate of change of a function refers to how much the output of the function changes with respect to changes in its input, typically expressed as the derivative of the function.

The initial value of a function refers to the value of the function at a specific point in its domain, often denoted as f(0) or f(x_0) for some value x_0 in the domain. It is called "initial" because it is usually the starting point for analyzing the behavior of the function over a range of inputs.

The given function is y=-150x+950,000, where x represents time in years and y represents the total population of pharaoh ants in Southeast Asia.

The initial value of the function is the y-intercept, which is 950,000. This means that at the beginning of the observation period (when x=0), there are 950,000 pharaoh ants in Southeast Asia.

The rate of change of the function is the coefficient of x, which is -150. This means that every year, the population decreases by 150,000 ants. Therefore, option A is correct because it states that the population decreases every year by 150,000 ants, which is the same as -150 multiplied by 1,000.

Answer:60

Step-by-step explanation:

The y-intercept is (0, 9), and the parabola has no x-intercepts.

An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx+c, where m denotes slope and c denotes the y-intercept.

X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.

To find the y-intercept of the parabola, we set x = 0 and solve for y:

y = 3x² - 9x + 9

y = 3(0)² - 9(0) + 9

y = 9

Therefore, the y-intercept is (0, 9).

To find the x-intercepts, we set y = 0 and solve for x:

0 = 3x² - 9x + 9

0 = x² - 3x + 3

Using the quadratic formula, we get:

x = [3 ± √((-3)² - 4(1)(3))]/(2(1))

x = [3 ± √(9 - 12)]/2

x = [3 ± √(-3)]/2

The square root of a negative number is not a real number.

The parabola does not intersect the x-axis, and therefore, there are no x-intercepts.

Therefore, the y-intercept is (0, 9), and the parabola has no x-intercepts.
