What is the volume of a hemisphere with a diameter of 30.3 ft, rounded to the
nearest tenth of a cubic foot?
Answer: its is 300 hope this helps Pls give me brainly
Step-by-step explanation: Remember that the tens place is two moves from the left of the decimal point (if it exists). To round to the nearest ten (nearest 10), we use the whole numbers place to determine whether the tens place rounds up or stays the same.
Solution steps:
Step 1: Locate and underline the ten place (0) and look to the right (3):
303
Step 2: The digit to the right (3) is 4 or below. So, we replace it by a 0 (zero), then we get 300 as the answer.
In short: 303 rounded to the nearest ten is 300.

X =5
Answer and Step-by-step explanation:
First, distribute the 2 to the 4x and 4.
[tex]\frac{8x + 8}{3}[/tex]
This can be the final answer, or you can have it as [tex]\frac{8x}{3} +\frac{8}{3}[/tex].
I'm not sure about the X =5, but I think it is saying that x is equal to 5, so we will plug 5 in to the equation.
[tex]\frac{8(5)}{3} + \frac{8}{3} \\\\\\ \frac{40}{3} + \frac{8}{3} \\\\\\ \frac{48}{3} = 16[/tex]
When x is equal to 5, 16 is the answer.

What happens when a function tries to assign or change a value of a variable that has been defined at the module level
When Python constructs a function, it also generates a temporary variable with the same name, and only the function can access the value of that variable.
What is Using a temporary variable?Using a temp variable is the quickest and easiest way to switch the values of two variables. Using the formula temp = a, the first variable's value is stored in the temp variables. By doing this, you can change the values of the two variables so that a = b before assigning the value of temp to the second variable.Tuple packing and sequence unpacking are two additional methods for changing the values of two variables without the usage of a temporary variable. Using commas to divide up the pieces in a tuple is one method of creating a tuple. Additionally, Python examines a task's right side before its left. As a result, the variables are packed into a tuple on the right side of the statement by using commas to separate them, and they are unpacked on the left side using the same number of target variables separated by commas.As long as the statement has the same number of variables on both sides as there are variables, this approach of variable swapping and permutation can be applied to more than two variables.To Learn more About temporary variable Refer To:

What is inverse proportion?Two quantities a and b are said to be in inverse proportion if an increase in quantity a, there will be a decrease in quantity b, and vice-versa. In other words, the product of their corresponding values should remain constant. Sometimes, it is also known as inverse variation.
That is, if ab = k, then a and b are said to vary inversely. In this case, if b1, b2 are the values of b corresponding to the values a1, a2 of a, respectively then a1 b1 = a2 b2 or a1/a2 = b2 /b1
Given,
Food for 300 people will Last for 4 days.
Attending people = 400
Let the food for 400 will last for x days.
According to the question,
300 × 4 = 400 × x
x = 300 × 4 /400

what is coordinates ?When locating points or other geometrical objects precisely on a manifold, such as Euclidean space, a coordinate system is a technique that uses one or more integers or coordinates. Locating a point or item on a two-dimensional plane requires the use of coordinates, which are pairs of integers. Two numbers called the x and y coordinates are used to describe a point's location on a 2D plane. a collection of integers that represent specific locations. The figure often has two numbers. The first number denotes the front-to-back measurement, while the second number denotes the top-to-bottom measurement. For example, in (12.5), there are 12 units below and 5 above.

When the equations 3x 5y 9 and 5x 3y 7 are solved then the value of x y 2?
When these equations are solved, the value of x is 4 and the value of y is 3. Therefore, the value of x + y = 7.
To solve the system of equations, we will use the elimination method.
First, we multiply the first equation by 3 and the second equation by 5.
3(3x + 5y = 9)
5(5x + 3y = 7)
Then, we add the equations together:
9x + 15y = 27
25x + 15y = 35
Now, we subtract the second equation from the first to eliminate the x terms:
-16y = -8
y = 0.5
Next, we plug this value for y into one of the original equations and solve for x:
3x + 5(0.5) = 9
3x = 8.5
x = 2.83
Finally, we plug the values of x and y into the original equation to verify that they are correct:
3(2.83) + 5(0.5) = 9
So, the value of x is 2.83 and the value of y is 0.5. Therefore, the value of x + y = 2.83 + 0.5 = 3.33.

What is direct proportion?Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝. In fact, the same symbol is used to represent inversely proportional, the matter of the fact that the other quantity is inverted here.
Given,
No. of seats in 3rd row = 31
No. of seats in 6th row = 37
Seats increase at a constant rate
Let k is the rate of increment.
Difference between no. of seats = k × difference between no. of rows
Difference of seats in 3rd and 6th rows = k difference between the no. of rows
37 - 31 = k ×(6-3)
6 = 3k
k = 2
Thus, we can determine
Difference between the no. of seats is twice the difference between the no. of rows.
Difference between 6th and 20th row = 14 rows
Hence the difference between number of seats = 2 × 14 = 28 seats.
No. of seats in 20th row = No. of seats in 6th row + 28 seats
No. of seats in 20th row = 37 + 28 = 65
Hence, there will be 65 seats in 20th row.

A quadratic equation is shown below: x2 − 8x + 13 = 0 Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers? (5 points) Subtract 5 from both sides of the equation Subtract 3 from both sides of the equation Add 5 to both sides of the equation Add 3 to both sides of the equation
Answer:
Add 3 to both sides of the equation
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left ([tex]x^2 - 8x + 13[/tex]) into an expression that is a perfect square. So what number should you add to both sides such that [tex]x^2 - 8x + (13 + j)[/tex] can be factored into [tex](x-p)^2[/tex] ? Well, we can approach it like this:
Since [tex](x-p)^2[/tex] can be turned into [tex]x^2 -2px + p^2[/tex], and our original form was [tex]x^2 - 8x + (13 + j)[/tex], we quickly realize that [tex]-2px = -8x[/tex]. From there, we can easily tell that [tex]p = 4[/tex]
Plug this into our last value [tex]p^2[/tex] to get 16. Therefore, if we compare this with our original equation again [tex]x^2 - 8x + (13 + j)[/tex], we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that [tex]x^2 - 8x + 13[/tex] is very close to [tex]x^2 - 8x + 16[/tex] which can be factored into [tex](x-4)^2[/tex]. But for now, the solution above will suffice. I hope this helps :))

Here the 10th term of this arithmetic sequence is 999.
What is an arithmetic sequence in math?An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.A series of integers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.Using the method for locating the nth term, we may locate a particular term in an arithmetic series. Step 1: An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. Therefore, enter the numbers a = 2 and d = 3 into the formula to determine the nth term.Given data :
an = n³ - 1
a1 = 1³ - 1 = 1 - 1 = 0
a2 = 2³ - 1 = 8 - 1 = 7
a3 = 3³ - 1 = 27 - 1 = 26
a4 = 4³ - 1 = 64 - 1 = 63
a5 = 5³ - 1 = 125 - 1 = 124
a10 = 10³ - 1 = 1000 - 1 = 999
I saw that these numbers were one less than the cubes. So the answer is
