Answer:

16/3 pounds

Step-by-step explanation:

We are give that each friend took 2/3 pound of grapes from the bowl. Therefore, to know the total amount taken by the four friends, we will simply do cross multiplication as follows:

1 friend .................> 2/3 pounds

4 friends ...............> ?? pounds

Amount taken by the 4 friends = [4*(2/3)] / 1 = 8/3 pounds

The bowl originally had 8 pounds and 8/3 pounds were taken, therefore:

remaining amount = 8 - 8/3 = 16/3 pounds                                                                           hope this helps!

Step-by-step explanation:

its like a bar graph but joint. theres no space between two consecutive bars

The equation that represents the situation is:

d = 525h

In this equation, d represents the distance traveled and h represents the number of hours spent flying. The equation states that the distance traveled (d) is equal to the product of the speed (525 miles per hour) and the number of hours spent flying (h). This equation shows the relationship between the distance and time for the airplane flying at a constant speed of 525 miles per hour.

       The Equation Representing The Situation is:

       d  =  525 *  h

Make A Plan:

We need to find the Equation representing the relationship between the distance traveled (D) and the number of hours spent flying (H).

The Airplane is flying at a Constant Speed of 525 Miles Per Hour (mph). However, The Distance Traveled is Equal to the speed Multiplied by the Time Spent Flying.  

        d   =   525  *   h

        The Equation Representing The Situation is:

        d  =  525 *  h

The solution to the equation -2/(x - 8) = (x - 1)/(x + 2) is x = 3 after checking for extraneous solutions.

To solve the equation

-2/(x - 8) = (x - 1)/(x + 2)

We can start by cross-multiplying to eliminate the fractions

-2(x + 2) = (x - 1)(x - 8)

Simplifying both sides, we get

-2x - 4 = x² - 9x + 8

Bringing all the terms to one side, we get

x² - 7x + 12 = 0

Now we can factor the quadratic equation to get

(x - 3)(x - 4) = 0

So the solutions are x = 3 and x = 4. However, we need to check for any extraneous solutions that may have been introduced by the original equation.

Plugging in x = 3 to the original equation, we get

-2/(3 - 8) = (3 - 1)/(3 + 2)

Which simplifies to

2/5 = 2/5

Therefore, x = 3 is a valid solution.

Plugging in x = 4 to the original equation, we get

-2/(4 - 8) = (4 - 1)/(4 + 2)

Which simplifies to

1/2 = 3/6

Therefore, x = 4 is not a valid solution.

So the only solution to the equation is x = 3.

Option 3) Sometimes is the correct answer, Sometimes an equilateral triangle is similar to a scalene triangle.

If the respective sides are proportional and the corresponding angles are congruent, two triangles are comparable. An equilateral triangle has three congruent sides and three congruent angles, so any triangle that is similar to an equilateral triangle must also have three congruent angles. However, a scalene triangle has no congruent sides and no congruent angles, so it is possible for a scalene triangle to be similar to an equilateral triangle only if it has the same angle measurements as an equilateral triangle, but with different side lengths. Therefore, a scalene triangle can be similar to an equilateral triangle, but it is not always the case.

In general, if two triangles are similar, it means that they have the same shape but possibly different sizes. In the case of an equilateral triangle and a scalene triangle, if they are similar, then it means that the scalene triangle has the same angles as the equilateral triangle, but its sides are of different lengths. So it is possible for a scalene triangle to be similar to an equilateral triangle, but not in all cases.

The unit price of the portion of the chicken will be $0.50.

To find the portion cost of the chicken, we need to know how much it costs per ounce, and then multiply that by the number of ounces in a serving.

We can begin by calculating the cost per ounce of chicken by dividing the cost per pound by the number of ounces in a pound:

$2 (cost per pound) ÷ 16 (ounces per pound) = $0.125 (cost per ounce)

Now that we know the cost per ounce, we can find the portion cost of the chicken by multiplying it by the number of ounces in a serving:

$0.125 (cost per ounce) × 4 (ounces per serving) = $0.50

So the portion cost of the chicken is $0.50 . So the answer is

The x-coordinates of the left edges of the rectangles are 1,5/4,6/4,7/4.

The area of this region with a Riemann Sum is 0.7595.

A specific type of approximation of an integral by a finite sum in mathematics is known as a Riemann sum. It bears the name of the German mathematician Bernhard Riemann from the nineteenth century. Approximating the area of functions or lines on a graph, as well as the length of curves and other approximations, is a highly typical use.

Given function is f(x) = 1/x on the interval [1,2] is shown.

The four rectangles of width 1/4 are present.

From the figure we can see that the x coordinate of the left edges of the rectangle are:

1,5/4,6/4,7/4

Now we plug these values in the function to find the height of rectangles.

For x=1 ,f(x) = 1

For x=5/4 ,f(x) = 4/5

For x=6/4 ,f(x) = 4/6

For x=7/4 ,f(x) = 4/7

Now, Area = length*width, and width of each rectangle is 1/4

Area of rectangle 1 = 1*1/4 = 1/4

Area of rectangle 2 = 4/5*1/4 = 1/5

Area of rectangle 3 = 4/6*1/4 = 1/6

Area of rectangle 4 = 4/7*1/4 = 1/7

Total Area is = 1/4+1/5+1/6+1/7  = 0.7595

This is an overestimation of ln(2).

Step-by-step explanation:

The number of cookies in the jar initially was 42

To find out how many cookies were in the jar initially, we can use algebra to represent the problem. Let x be the number of cookies in the jar initially. After Latoya took half of the cookies, Mark took 1/3 of the remaining cookies, Kandi took 1/4 of the remaining cookies, and Shannon took 1 cookie, there are 2 cookies left in the jar.

We can use this information to set up the equation:

x/2 - (x/2)/3 - (x/2)/4 - 1 - 2 = 0.

By solving this equation, we get x = 42. This means there were 42 cookies in the jar initially. To find out how many cookies were there before Latoya came, we just add the 2/3 of a cookie that was left over to the 2 whole cookies we know of.

So, 42+2/3 = 42.67 which means 42 cookies were there before Latoya came.

The value of r'(1) is 125

The chain rule is a formula used to compute the derivative of a composite function. A composite function is a function that is formed by taking the output of one function and using it as the input of another function.

To find the derivative of r(x), we can use the chain rule:

r'(x) = f'(g(h(x))) × g'(h(x)) × h'(x)

Then, to find r'(1), we can evaluate this expression at x = 1:

r'(1) = f'(g(h(1))) × g'(h(1)) × h'(1)

We are given that h(1) = 3, g(3) = 5, h'(1) = 5, g'(3) = 5, and f '(5) = 5. Therefore, we can substitute these values into the expression for r'(1):

r'(1) = f'(g(h(1))) × g'(h(1)) × h'(1)

= f'(g(3)) × g'(3) × 5 (since h(1) = 3 and h'(1) = 5)

= f'(5) × 5 × 5 (since g(3) = 5 and g'(3) = 5)

= 5 × 5 × 5 (since f'(5) = 5)

= 125

To begin with, let's first understand what a rectangular prism is. A rectangular prism is a three-dimensional object that has six faces,

Each of which is a rectangle. The faces are parallel and congruent, meaning they have the same size and shape. Now, coming to your question, you are asking about the area of one face of the rectangular prism.

Since all the faces of a rectangular prism are rectangles, the area of one face can be calculated by multiplying the length and width of the face.

For example, if the length of the rectangular prism is 5 units and the width is 3 units, the area of one face would be 5 x 3 = 15 square units. The units used to measure the length and width will also determine the unit of measurement for the area.

So, to summarize, the area of one face of a rectangular prism can be found by multiplying the length and width of that face.

if you have a rectangular prism with dimensions of length = 5 units, width = 4 units, and height = 3 units, you can calculate the area of each face as follows:

1. Length x width: 5 x 4 = 20 square units
2. Length x height: 5 x 3 = 15 square units
3. Width x height: 4 x 3 = 12 square units

So, the areas of the three different pairs of faces for this rectangular prism are 20, 15, and 12 square units, respectively.

To ensure the preservation of the clinical specimen for viral isolation, it should be stored at a specific temperature. The recommended temperature for storing the specimen is generally between 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit).

Storing the clinical specimen in viral transport medium at a temperature range of 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit) is commonly advised for preserving the viability of the virus. This temperature range helps to slow down the viral activity and prevents the specimen from deteriorating while awaiting processing. It provides an environment that can maintain the integrity of the viral particles until laboratory procedures can be carried out the following week. It's important to follow the recommended storage temperature to ensure accurate results and successful viral isolation from the specimen.

A D. simple random sample is a sample in which every member of the population has an equal chance of being chosen.

A. Systematic: In a systematic sample, the population is first ordered or arranged in some systematic way, such as by alphabetical order or numerical sequence. Then, a starting point is randomly selected, and subsequent members are chosen at regular intervals from the ordered list. This method ensures that every member of the population has an equal chance of being selected.

B. Probability: The term "probability sample" is a general concept that encompasses various sampling methods. It refers to any sample in which each member of the population has a known nonzero probability of being selected. Probability sampling methods include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.

C. Stratified: In stratified sampling, the population is divided into distinct subgroups or strata based on specific characteristics or attributes. Then, a random sample is taken from each stratum in proportion to its representation in the overall population. This method ensures that the sample is representative of the population across different subgroups or strata.

D. Simple random: A simple random sample is a sampling method where each member of the population has an equal and independent chance of being selected. It involves selecting individuals randomly and without any specific pattern or grouping. This method ensures that each member of the population has an equal probability of being chosen, leading to unbiased estimates and generalizability to the larger population.
