Which graph represents the function f(x) = −|x − 2| − 1?

Answer:

21

Step-by-step explanation:

We are given that Stanley  is putting wallpaper strips on his  bathroom walls that have a total area of 460 square  feet.

Area of each strip =22 square feet

We have to find the number of strips of wallpapers  will Stanley need to fully cover his walls.

In order to find the number of strips of wall papers we are dividing the area of walls by area of each strips

Number of strips of wall paper=[tex]\frac{460}{22}[/tex]

Number of strips of wall paper=20.909 =21 strips of wallpaper

Hence, Stanley will need strips of wallpaper to cover fully his walls=21

Inequality that models the given situation is given by 6x+2 ≤ 32.

Price of each sandwich is equals to $5 or less.

" Inequality is defined as the algebraic expression which represents the relation between the variables using the sign of inequality < , > , ≤ , ≥."

According to the question,

Given,

Number of sandwiches = 6

Amount spend on kids meal = $2

Total money with Charlie = $32

'x' represents the cost of each sandwich

As per the condition inequality is given by,

[tex]6x+2 \leq 32\\\\\implies 6x \leq 32 - 2\\\\ \implies 6x \leq 30 \\\\ \implies x \leq \frac{30}{6} \\\\\implies x\leq \$5[/tex]

Hence, Option(D) is the correct answer

Step-by-step explanation:

The fraction of the days of the year Regina have fog will be 438.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that, Regina has wet weather on about 3/10 of the days in a year. It has wet weather on about four times as many days as it has fog.

We have to find the fraction of the days of the year Regina have fog,

From the given conditions,

wet weather = 3/10 × days in year

wet weather = 4 × days of fog

Combined both the equation,

3/10 × 365 = 4 × x

x=3×365/10×4

x=438

Thus, the fraction of the days of the year Regina have fog will be 438.

39 DVDs are about other subjects.

To determine the number of DVDs about other subjects in the school library, we must first calculate the number of DVDs dedicated to science and history. We start by finding 45% of 260 DVDs for science and 40% of 260 DVDs for history.

Science DVDs: 45% of 260 = 0.45 * 260 = 117
History DVDs: 40% of 260 = 0.40 * 260 = 104

Adding the numbers of science and history DVDs gives us the total number of DVDs not about other subjects:

117 (Science) + 104 (History) = 221

To find the number about other subjects, we subtract the total number of science and history DVDs from the total collection:

260 (Total) - 221 (Science and History) = 39 DVDs about other subjects.

The statement 'All squares are rectangles' written as a conditional is 'If a shape is a square, then it is a rectangle.' This forms a strict conditional that states the sufficiency of the condition of being a square for the necessity of being a rectangle.

When we are asked to write the statement 'All squares are rectangles' as a conditional, we are forming what is called a strict conditional. This type of conditional states that if the antecedent (the 'if' part) is true, then the consequent (the 'then' part) must also be true without any exceptions. In our example, the antecedent is the condition of being a square, and the consequent is the condition of being a rectangle.

Strict Conditional Example

If a shape is a square, then it is a rectangle. This expresses a clear relationship between two properties: being a square and being a rectangle. This conditional is considered strict because there are no exceptions to the rule; every square is, by definition, a rectangle.

The bar of chocolate should be broken [tex]\boxed{\bf 71\text{\bf\ times}}[/tex], so that it is separated into individual squares.

Further explanation:

Given that the bar of chocolate is eight pieces high and nine pieces long.

First break the chocolate horizontally [tex]7\text{ times}[/tex] since, it is eight pieces high.

Now, the broken piece of chocolate is divided into nine single strips of eight pieces each.

Each nine single strip is broken [tex]8\text{ times}[/tex].

Therefore, total number of times the chocolate bar is broken is calculated as follows:

[tex]\begin{aligned}\text{Total number of times}&=7+(8\cdot 8)\\&=7+64\\&=71\end{aliogned}[/tex]

Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.

Now, break the chocolate vertically [tex]8\text{ times}[/tex] since, it is nine pieces long.

Now, the broken piece of chocolate is divided into nine single strips of nine pieces each.

Each nine single strip is broken [tex]7\text{ times}[/tex].

Therefore, total number of times the chocolate bar is broken is calculated as follows:

[tex]\begin{aligned}\text{Total number of times}&=8+(9\cdot 7)\\&=8+63\\&=71\end{aliogned}[/tex]

Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.

Final answer:

The profit is calculated by subtracting the group's expenses from their total earnings, resulting in a profit of $206.

Explanation:

The student's question is about calculating the profit made by a youth group from washing cars. To find the profit, we subtract the group's expenses from their earnings. Here is the calculation:

Total earnings from car washing: $285.

Total expenses: $79.

To find the profit, subtract expenses from earnings: $285 - $79 = $206.

Therefore, the youth group made a profit of $206 from washing cars.

In the given scenario, we analyze variable costs, fixed costs, and total costs in a manufacturing context where the business sells a product at a set price and bears specific levels of fixed and variable costs. Average variable cost is obtained by dividing total variable costs by the quantity produced, which impacts the total cost and pricing strategies for the business.

The scenario you're describing involves concepts of variable costs, fixed costs, and total costs in the context of a manufacturing business. At zero production, the fixed costs amount to $16,000. These costs do not change regardless of production levels. As production increases, the variable cost, which is $5.35 per unit, is added to the fixed costs. Total cost for any given level of production is the sum of variable and fixed costs. When a company sells the product for $8.20 per unit and can sell all that it produces, it gives us a context to calculate break-even points, profit margins, and other relevant financial metrics.

For example, average variable cost (AVC) is determined by dividing the total variable cost by the quantity of output. If a hypothetical scenario is given where the company produces 80 units, the total variable cost would be 80 units times $5.35, resulting in $428. Therefore, the AVC would be $428/80, which is $5.35 per unit.

As output increases, fixed costs per unit decline because these costs are spread over more units, making the average variable cost a relatively bigger component of the total cost. This principle is crucial for businesses as they plan production and pricing strategies to cover costs and achieve profitability.

Average variable cost cannot be calculated without the quantity of output. The total cost is the sum of fixed costs and variable costs.

To find the  of producing a product, we divide the by the . In this case, the variable cost is $5.35 per unit. To calculate the average variable cost, we need to know the quantity of output. Since the question does not provide the quantity of output, we cannot calculate the average variable cost.

The fixed costs of the hand tool manufacturer are given as $16,000. Fixed costs do not change with the quantity of output. The total cost is the sum of the fixed costs and the variable costs. To calculate the total cost, we would need to know the quantity of output.
