Answer:

(x - 1)(x² + x + 1)

Step-by-step explanation:

x³ - 1 is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²)

here a = x and b = 1, thus

x³ - 1 = (x - 1)(x² + x + 1)

To solve for F in the conversion formula, subtract 273.15, multiply by ([tex]\frac{5}{9}[/tex]), and add 32. The freezing point of water in Fahrenheit is 32 °F. Liquid nitrogen is colder than dry ice.

Solving the Temperature Conversion Formula

To solve the formula K = [tex]\frac{9}{5}[/tex][F-32] + 273.15 for F (Fahrenheit), we will isolate F in the equation. Here is the step-by-step process:

Subtract 273.15 from both sides: K - 273.15 = [tex]\frac{9}{5}[/tex][F - 32]

Multiply both sides by [tex]\frac{5}{9}[/tex] to get: F - 32 = (K - 273.15) × [tex]\frac{5}{9}[/tex]

Add 32 to both sides to solve for F: F = (K - 273.15) × [tex]\frac{5}{9}[/tex] + 32

Converting Kelvin to Fahrenheit

The freezing point of water is 273.15 Kelvin. To find this temperature in Fahrenheit:

F = (273.15 - 273.15) × [tex]\frac{5}{9}[/tex] + 32 = 32 °F

Comparing Temperatures

Dry ice has a temperature of -78°C, which is equivalent to -108.4°F. Liquid nitrogen boils at 77 K, which is about -196°C or -320.8°F. Therefore, liquid nitrogen is colder than dry ice.

Answer:

The graph of f(x) is shifted up 50 units

The graph of f(x) is shifted right 10 units

The graph of f(x) is reflected over the x-axis

Step-by-step explanation:

we have

[tex]f(x)=x^{2}[/tex]

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the origin (0,0)

[tex]g(x)=-5x^{2}+100x-450[/tex]

This is a vertical parabola open downward

The vertex is a maximum

The first thing to note is that fx) is a parabola that opens up and g(x) opens down, so a reflection across the x-axis must have been applied.

Find the vertex of g(x)

Convert to vertex form

[tex]g(x)=-5x^{2}+100x-450[/tex]

Complete the square

[tex]g(x)=-5(x^{2}-20x)-450[/tex]

[tex]g(x)=-5(x^{2}-20x+100)-450+500[/tex]

[tex]g(x)=-5(x^{2}-20x+100)+50[/tex]

[tex]g(x)=-5(x-10)^{2}+50[/tex]

The vertex is the point (10,50)

so

To translate the vertex of (0,0) to (10,50)

The rule of the translation is

(x,y) ------> (x+10,y+50)

That means ----> The translation is 10 units at right and 50 units up

therefore

Answer:

Total cost =$33.47    Tip=$5.58

Step-by-step explanation:

$27.89÷5=5.578     5.578 rounded up to 2 digits=$5.58

$27.89+$5.58=$33.47

total cost is $33.47    tip=$5.58

Lucia should tip $5.58 for a 20% tip on her $27.89 pizza order. The total cost including the tip is $33.47.

To compute the tip Lucia should give for her pizza delivery, we need to calculate 20% of the total cost of the pizzas, which is $27.89. We first convert the percentage into decimal form by dividing 20 by 100, which gives us 0.20. Then we multiply this decimal by the total cost of the pizzas:

Tip =  0.20 imes $27.89 = $5.578

Since we usually round money to the nearest cent, the tip would be approximately $5.58. Now, to find the total cost including the tip, we add the tip to the original total:

Total Cost = Original Cost + Tip

Total Cost = $27.89 + $5.58 = $33.47

Therefore, the total amount Lucia would pay for the pizzas, including a 20% tip, is $33.47.

Add similar variables (4x + 2x)

6x + 16 = 52

Move the 16 to the other side by subtracting 16 from both sides

6x = 36

Divide both sides by 6 to get rid of the 6 in front of the x

x = 6

Answer:

x=6

Step-by-step explanation:

4(x+4)+2x=52

Answer:

-12, -7, -4, -1, 0, 2, 5

Step-by-step explanation:

The larger a negative number the less value it actually has, whereas the larger a positive number the more value it has. You can think about it as if someone has taken something from you. If I take $12 from you you have less money than if I were to only take $7 from you. With positive numbers, you would have more money if I gave you 5 dollars than if I only gave you 2 dollars. You will always have more money if I give you money than if I were to take away money, that is why positive numbers are greater than negative numbers.

Part A

 [tex]A_{t}=22(12+w)[/tex]

Applying Distributive property: [tex]A_{t}=264+22w[/tex]

Part B

[tex]A_{t}=660\ ft^2[/tex]

Step-by-step explanation:

Attached is the model that belongs to this exercise (The model was missing)

The formula for calculate the area of a rectangle is:

[tex]A=lw[/tex]

Where "l" is the lenght and "w" is the width.

Part A

Notice that the dimensions of the new bathroom are:

[tex]l=22\ ft\\w=12\ ft[/tex]

We do not know the width of the new bathroom, but we know that both rooms will have the same length. Knowing this, we can write an expression for the total area of both rooms by using the Distributive Property:

[tex]A_{t}=22(12+w)[/tex]

Applying Distributive property:

 [tex]A_{t}=264+22w[/tex]

Part B

If the width of the bedroom is 18 feet, you need to substitute this value into the expression [tex]A_{t}=264+22w[/tex] in order to find the total square footage of the two rooms:

[tex]A_{t}=264+22w\\\\A_{t}=660\ ft^2[/tex]

Final answer:

The expression for the total area of both rooms, using the distributive property, is L × (12 ft + W). Given the width of the bedroom as 18 feet, the total square footage of the addition is 660 square feet.

Explanation:

Calculating the Area of Rooms

Part A: To write an expression for the total area of both rooms using the distributive property, let's denote the width of the new bedroom as W and the common length of both rooms as L. Both rooms have the same length, 22 feet, so L = 22 feet. The total area can be represented as the sum of the areas of both the new bathroom and the new bedroom.

Area of New Bathroom = L × 12 ft (since the width of the bathroom is given as 12 ft)
Area of New Bedroom = L × W (width of the bedroom is W)
Total Area = Area of New Bathroom + Area of New Bedroom
Using distributive property: Total Area = L × (12 ft + W)

Part B: Given the width of the bedroom is 18 feet, we can calculate the total square footage:
Total Area = 22 ft × (12 ft + 18 ft)

Total Area = 22 ft × 30 ft
Total Area = 660 square feet

Therefore, the total square footage of the two rooms is 660 square feet.

Answer:

A pound is a measure of weight and a cup is a measure of volume.

Step-by-step explanation:

You can't directly compare 1.07 pounds of sugar to 1.23 cups of sugar because they're measured in different units -- weight and volume -- and without a conversion factor (like density), they're not directly comparable. The solution is to convert one measurement to the other, such as by knowing that one cup of granulated sugar typically weighs about 0.44 pounds.

The reason you can't directly compare 1.07 pounds of sugar to 1.23 cups of sugar is because they're measured in two different units -- weight and volume, respectively. Without a known conversion factor (in this case, the density of sugar), you can't equate the two. It's like comparing apples to oranges, the two quantities just aren't compatible without some more information.

Let's consider a real-world example. Just like you can't compare how heavy an object is to how much space it takes up without knowing the material's density, the same goes for comparing sugar in pounds and cups.

The solution is to convert one measurement to the other. For instance, by knowing that one cup of granulated sugar typically weighs about 200 grams (or 0.44 pounds), you could convert your weights and volumes to make a meaningful comparison.

Answer:

440

Step-by-step explanation:

3 hundreds = 300

13 tens= 13 times 10=130

10 ones=10

300+ 130+ 10=

440

The number 440 as  per the statement 3 hundreds (300), 13 tens (130), and 10 ones = 10. Putting them together gives you 440.

Let's analyze the statement to find the number

3 hundreds, 13 tens, and 10 ones.

3 hundreds: This means you have three sets of one hundred. Each hundred is represented as 100. So, 3 hundreds would be

3 × 100 = 300.

13 tens: You have thirteen sets of ten. Each ten is represented as 10.

So, 13 tens would be 13 × 10 = 130.

10 ones: You have ten individual ones.

Now, let's add up all these components:

300 (for the hundreds) + 130 (for the tens) + 10 (for the ones) = 440

Therefore, the number describing in the statement is 440.

Answer: 9/11

Step-by-step explanation: (8,0) (-3, 9). Subtract x values, subtract y values. This is known as delta x and delta y. Slope is rise/run. When you subtract the two points, you are finding the different between them. You're able to plug these x values and y values into an equation and get the correct answer. If you substitute x in, you get y. If you substitute y in, you get x (if you simplify it to get x on one side). So, the change is y is on the top, and change in x is on the bottom. 9 is divided by 11. This is the slope. You can plot this point by rising 9 and running (x axis) 11.
