As she have 3⅞ pounds of soil, she doesn't have enough soil to fill the flowerpot.

To create a mixed fraction, a suitable fraction and a whole number must be combined. Usually, it denotes a value between 0 and 1. A mixed fraction is one that contains both a whole number and a fraction. One example of a mixed fraction is 1(1/3), where 1 is a whole number and 1/3 is a fraction.

Denise need 4 pounds of soil

By adding the mixed fraction we will know if its enough or not

[tex]$=1\frac{3}{4} + 2 \frac{1}{8}[/tex]

[tex]$=\frac{7}{4} + \frac{17}{8}[/tex]

[tex]$=\frac{14}{8} + \frac{17}{8}[/tex]

If In the lab, Trey has two solutions that contain alcohol and is mixing them with each other. The many milliliters of solution b he use, if the resulting mixture has 261 mL of pure alcohol is: 213.93mL.

Let x be the amount of solution B he used in milliliters.

We know that the amount of solution A  used = 4× x, and that the resulting mixture has 261 mL of pure alcohol.

Percentage of alcohol in solution A is 18% and in solution B is 50%.

Set up the proportion:

(0.18 × 4x + 0.50x) = 261

Simplifying,

0.72x + 0.50x = 261

1.22x = 261

x = 261 / 1.22

x = 213.93 mL (Solution b)

Trey used 213.93 mL of solution B and 3( 213.93mL) = 855.72 mL of Solution A.

Answer:(n+3)(n^2-3n+9)/125

Step-by-step explanation:

Answer:

(n+3)(n^2-3n+9)/125

Step-by-step explanation:

We can figure out the factored form of n^3+27/125 by adding all the brackets in the correct places. (I forgot what my math teacher called this process ;-;)

After adding the brackets it becomes:

(n + 3) (n² - 3n + 9) ÷ 125

(Our answer would be 125)

According to the given information in the question answer is  250.

Any decimal number is rounded down to the closest hundredth by the term "to the nearest hundredth." A hundredth is 1/100 or 0.01 in decimal form. For instance, increasing 2.167 to the closest tenth yields 2.17.

In this exercise, we must round the supplied number up to the nearest hundred, making it 10.2719. We must add two more decimal places to this number in order to round it to the nearest hundreds. Additionally, we saw that all of the numbers following the second decimal place are fewer than five, therefore they can be ignored and the result is 10.27.

Using the following formula, you can determine this:

x = (100 * 305) / 122

Where x is the original number and 122 is 100 + 22 (the 100 representing the original value and 22 representing the increase of 22%).

x = (100 * 305) / 122 = 250

The probability of each of the following events are given below:

What is Probability?

Probability is the measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1, with 0 representing no chance of the event occurring, and 1 representing a certainty that the event will occur. Probability is widely used in mathematics, statistics, and science to calculate the probability of a given event occurring. It is also used to assess risk and uncertainty in decision-making.

Event A: 0.306 or 30.6%

Event B: 0.44 or 44%.

Event A: The sum is greater than 9.

We have already computed this, the probability of getting a sum greater than 9 is 11/36, which can be simplified as 0.306 or 30.6%

Event B: The sum is not divisible by 2 and not divisible by 5.

To find the probability of this event, we need to find the number of outcomes that have a sum that is not divisible by 2 or 5.

We can calculate this by listing out all the possible outcomes and counting the number that have a sum that is not divisible by 2 or 5: (1,3), (1,4), (1,6), (2,3), (2,5), (3,1), (3,2), (3,4), (3,6), (4,1), (4,3), (4,5), (5,2), (5,4), (6,1), (6,3), (6,4) and (6,6)

There are 16 outcomes that have a sum that is not divisible by 2 or 5, so the probability of getting a sum that is not divisible by 2 or 5 is 16/36, which can be simplified as 0.44 or 44%.

The product meaning in maths is a number that we get to by multiplying two or more other numbers together.

What is Product?

In mathematics, a product is the outcome of multiplying two or more numbers together.

Let us consider the scenario.  A person had to buy 4 cupcakes. Each cupcake costs $5.

To calculate the total amount he needs to pay at the checkout counter, add the cost of each cupcake 4 times (as he needs to buy 4 cupcakes).

So, the answer will be -

5 + 5 + 5 + 5 = 20

If he needed 10 cupcakes, he would have to add the cost 10 times.

This is where the concept of multiplication and product can help him.

He can find the cost as -

4 times 5 or 4 × 5,

He can skip count by 5, four times and get the answer as 20.

Where:

Next, we would determine the constant of proportionality (k) for the distance (miles) and time (hours) on this table as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 6/2 ≠ 11/4 ≠ 34/9 ≠ 81/16

In conclusion, we can reasonably infer and logically deduce that the table shows a linear relationship because as the time (in hours) increases, the distance (miles) also increases. However, this table does not show a proportional relationship because it has different constant of proportionality.

Step-by-step explanation:

The inverse of a function is another function that "undoes" the original function. In other words, the composition of a function and its inverse results in the identity function.

To find the inverse of a function, you can follow these steps:

Replace the function with "y"

Switch the x and y variables

Solve for y (or in this case x)

So in this case, we can find the inverse of 8x^5+7 by replacing y with 8x^5+7, switching the x and y variables, and solving for x:

y = 8x^5+7

x = 8y^5+7

This is not an invertible function because it's not a one-to-one function, it's not a function of x.

Answer:

Hey there! The inverse of 8x^5+7 doesn't exist because it's not a function. Think about it like this, a function is like a machine that takes an input and gives you a unique output. But in this case, the machine isn't working correctly and it doesn't give you a unique output for a given input. So, in simple terms, it doesn't have an inverse.

________________________________________________________

To determine if an equation has an inverse, we need to check if it is a one-to-one function. A one-to-one function is a function in which every unique input corresponds to a unique output. If an equation is one-to-one function, then it has an inverse. If it's not one-to-one function, then it doesn't have an inverse.

To find the inverse of a linear equation, we can follow these steps:

1. Switch the x and y variables

2. Solve for y (or x)

3. Replace y (or x) with f^-1 (x) (or f^-1 (y))

For example, if we have the equation y = 2x+1, we can follow these steps:

1. x = 2y+1

2. x-1 = 2y

3. f^-1(x) = (x-1)/2

So, the inverse of the equation y = 2x+1 is f^-1(x) = (x-1)/2
