Step-by-step explanation:

Answer: -7, -4, -2, 0, 0.9, 0.99, 0.999, 1

Step-by-step explanation: The numbers you need to pick, have to be less than or equal to 1. -7, -4, -2, 0, 0.9, 0.99, 0.999, and 1, are less than or equal to 1. 1, 1.001, 1.01, 1.1, 2, 4, 6, and 9, are all greater than one, so they won't fit the equation.

Answer:

[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]

Step-by-step explanation:

[tex]\textsf{For this problem, we are asked to solve for the \underline{Area} of a Rectangle.}[/tex]

[tex]\textsf{We are given the \underline{Perimeter}, and the \underline{Length}.}[/tex]

[tex]\textsf{We should begin by identifying the formulas for Perimeter and Area.}[/tex]

[tex]\mathtt{Perimeter = Length + Length + WIdth + Width}[/tex]

[tex]\mathtt{Area = Length \times Width}[/tex]

[tex]\textsf{Because we're given the Perimeter and the Length, we can identify the Width.}[/tex]

[tex]\large\underline{\textsf{Substitute:}}[/tex]

[tex]\mathtt{38 cm = 12.5 + 12.5 + Width + Width}[/tex]

[tex]\large\underline{\textsf{Combine Like Terms:}}[/tex]

[tex]\mathtt{38 cm = 25 cm+ 2(Width)}[/tex]

[tex]\large\underline{\textsf{Subtract 25 from both sides:}}[/tex]

[tex]\mathtt{13 cm = 2(Width)}[/tex]

[tex]\large\underline{\textsf{Divide By 2:}}[/tex]

[tex]\mathtt{6.5 cm = Width}[/tex]

[tex]\textsf{Now that we know the Width, we can identify the Area.}[/tex]

[tex]\large\underline{\textsf{Substitute:}}[/tex]

[tex]\mathtt{Area = 12.5 cm \times 6.5cm}[/tex]

[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]

Answer:

275.5 square inches of pizza remaining

Step-by-step explanation:

The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.

The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.

The area of the entire pizza is:

A = πr^2 = 3.14 x 10^2 = 314 square inches.

If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.

The remaining area of the pizza is:

(7/8) x 314 = 275.5 square inches.

Therefore, there are 275.5 square inches of pizza remaining.

Answer:

16 pints

32 cups

Step-by-step explanation:

Total: 8 quarts.

Pints:

There are 2 pints in 1 quart.

It is given that there are 8 quarts. Multiply 2 pints with 8 quarts:

(8 quarts) * (2 pints/1 quart) = 16 pints/8quarts

16 pints

Cups:

There are 4 cups in 1 quart.

It is given that there are 8 quarts. Multiply 4 cups with 8 quarts:

(8 quarts) * (4 cups/1 quart) = 32 cups/8 quarts

32 cups.

Gallons:

There are 4 quarts in 1 gallon.

It is given that there are 8 quarts. Divide 4 quarts with 8 quarts:

(8 quarts)/(4 quarts per gallon) = 2 gallons

2 gallons.

area of parallelogram= BASE ×HEIGHT

Area=18×6

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.

q and t are alternate interior

r and k are alternate interior

W is 79

The mistake he made is equating an alternate interior angle to an alternate exterior angle

1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.

2. check the picture for translation of the angles

3. 8 angles are created, 4 alternate interior and 4 alternate exterior

Angles 6,4 and 2 are congruent to 8

The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.

Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:

[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]

Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.

The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).

Now we can solve for x:

[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]

[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]

[tex]0.2x = 7.2 cm^3[/tex]

[tex]x = 36 cm^3[/tex]

Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

Answer:

A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7. So, assuming that's the type of "Mean" your talking about, there is no way of telling what the means are seeing as the picture only shows the averages.

Answer:

a: -4p² + 5q² - 4pq - 2

b: -3x + 3y

Step-by-step explanation:

When we combine like terms, we get:

(-6p²+8q² - 2pq- 5) + ( 2p² -3q² -2pq+3) = -4p² + 5q² - 4pq - 2

Therefore, the simplified expression is -4p² + 5q² - 4pq - 2.

Next:

(5x+6y)+ (-8x -3y) = 5x - 8x + 6y - 3y

Combining like terms gives us:

5x - 8x + 6y - 3y = -3x + 3y

Therefore, the simplified expression is -3x + 3y.

Answer: Option A, $12.50

Step-by-step explanation: Jeff spent 3/8 of his money, which can be represented by the equation as follows:

1 - 3/8 = 5/8

where 1 represents 8/8, or $20, and 5/8 represents the remainder of Jeff's money.

To find how much money Jeff has left, we can multiply his initial investment by 5/8:

$20 × 5/8 = $100/8, or $12.50

Hence, Jeff has $12.50 leftover, which is represented by option A.

To find the average speed, we divide the total distance traveled by the time taken:

Average speed = Total distance ÷ Time taken

Therefore, Gianna and her family's average speed is:

Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)

We use an equation to solve this problem.

Equation: Average speed = Total distance ÷ Time taken

Where:

Total distance = 175 miles

Time taken = 3 hours

Substituting these values into the equation, we get:

Average speed = 175 miles ÷ 3 hours

Therefore, the answer is an equation:

Average speed = 175 miles ÷ 3 hours
