The equation for the distance in kilometers to Proxima Centauri is

D = 3.99 x 10¹³

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total distance from Earth to the closest star Proxima Centauri be = D

Now , the value of distance D = 39,900,000,000,000

Now , the equation to find the scientific notation is done by calculating the number of zeros in the equation

So , The distance D has 11 zeros in it

So , the distance D can be written as powers of 10 in the form

Distance D = 399 x 10¹¹

Now , 399 can be written as 3.99 x 10²

So , the equation can be simplified as

Distance D = 3.99 x 10² x 10¹¹

Distance D = 3.99 x 10¹¹⁺²

Distance D = 3.99 x 10¹³

Therefore , the value of D is 3.99 x 10¹³

Hence , The distance in kilometers to Proxima Centauri is 3.99 x 10¹³

Answer:

p=3

Step-by-step explanation:

To solve, we need to isolate the variable: p

5−p+6 = 8

Combine like terms

5+6 -p =8

11 -p=8

Subtract 11 from both sides

-p = -3

Divide both sides by -1

p=3

Answer:

37

Step-by-step explanation:

There are 2 ways to do this, the first is to just count the number of shaded squares (35)

The second is to find the area of the larger shaded square and subtract the smaller un-shaded rectangles

The large square is 7x7=49 squares

There are two 2x3 rectangles, which are 6 each

49-6-6=37

Answer:

x =11

Step-by-step explanation:

6x + 9 = 75

Subtract 9 from each side

6x + 9-9 = 75-9

6x = 66

Divide each side by 6

6x/6 = 66/6

x = 11

(2x - 10) - (3x^2 + 10x) + (2x^3+ 3x^2)

Remove parentheses:

2x - 10 - 3x^2 + 10x + 2x^3+ 3x^2

Simplify:

2x - 10 - 3x^2 + 10x + 2x^3+ 3x^2

Group like terms:

2x^3 -3x^2 + 3x^2 + 2x -10x-10

Add similar elements -3x^2 + 3x^2:

2x^3+2x-10x-10

Add similar elements 2x-10x=-8x:

2x^3-8x-10

Your Answer Is (A) 2x^3-8x-10

plz mark me as brainliest :)

Answer:

A

Step-by-step explanation:

Let's first expand these parentheses. Remember that when we have a negative sign in front of a parentheses, that means we're multiplying each term within the parentheses by -1:

2x - 10 -3x^2 - 10x + 2x^3 + 3x^2

Now combine like terms. Like terms are the ones that have the same degree of x: 2x and -10x are like terms; -10 is by itself; -3x^2 and 3x^2 are like terms; 2x^3 is by itself. So:

2x^3 + (-3x^2 + 3x^2) + (2x - 10x) - 10

2x^3 - 8x - 10

Thus, the answer is A.

What measure of center will be most affected by the new data point?

The mean will be most affected.

Answer:

The mean.

Step-by-step explanation:

48 messages is a very high compared to the rest of the data so it will effect the mean. The median and the mode will be unchanged and the IQR will only change slightly. The mean will change form 8.9 to 10.2.

3 1/2 lb = 56 oz​

OR

3.5 lb = 56 oz

Answer:

52 ounces.

Step-by-step explanation:

1 pound =16 ounces. From there you can just convert. So, 3*16=48 ounces., and 1/2 pound *16 ounces equal 4 ounces.

4+48=52 ounces.

So in total, 3 1/2 pound equals to 52 ounces.

The sum of the angles of a triangle is 180 degrees

x+77+31 = 180

Combine like terms

x + 108 = 180

Subtract 108 from each side

x+108-108 = 180-108

x =72

Answer:

72⁰

Step-by-step explanation:

By angle sum property:

x + 77 + 31 = 180

x = 180 - 108

x = 72⁰

Step-by-step explanation:

The mean of the data describes the data set , because it is the average of all the values of the set

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the data set be represented as A

Now , the value of A is noted

And , the median of the data set is the middle term of the set

where the mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values

So , the average values of the set determines the data values as it is a compilation of all the data values

The volume of steel used to make the bathysphere is approximately 53,481 cubic inches.

To estimate the volume of steel used to make the bathysphere, we need to calculate the volume of the sphere and subtract the volume of the windows. The volume of the sphere can be calculated using the formula for the volume of a sphere: V = (4/3)πr³, where r is the radius of the sphere. Since the diameter of the bathysphere is 56 inches, the radius is half of that, which is 28 inches. Converting to meters, the radius is approximately 0.7112 meters.

Now we can calculate the volume of the sphere: V = (4/3)π(0.7112)³ ≈ 0.8827 cubic meters.

The volume of each window can be calculated using the formula for the volume of a cylinder: V = πr²h, where r is the radius of the window and h is the height of the window. The radius of each window is half of the diameter, which is 5 inches or approximately 0.127 meters. The height of each window is 1.5 inches or approximately 0.0381 meters.

Now we can calculate the volume of each window: V = π(0.127)²(0.0381) ≈ 0.0024 cubic meters.

Since there are three windows, the total volume of the windows is 3 × 0.0024 ≈ 0.0073 cubic meters.

To estimate the volume of steel used to make the bathysphere, we subtract the volume of the windows from the volume of the sphere: approximately 0.8827 - 0.0073 ≈ 0.8754 cubic meters.

Finally, we convert the volume to cubic inches to estimate the amount of steel used: 0.8754 × 61023.7 ≈ 53481 cubic inches. Rounding to the nearest whole number, the volume of steel used to make the bathysphere is approximately 53,481 cubic inches.

Answer:

Final answer:

The lower bound of the number rounded to 2 decimal places is 45.54, and the upper bound is 45.56.

Explanation:

To find the lower and upper bounds of a number when it is rounded to 2 decimal places, we need to consider the two possible values that round down and round up from the given number.

In this case, the number is 45.55.

The lower bound is the number rounded down.

When we round down 45.55 to 2 decimal places, we get 45.54.

The upper bound is the number rounded up.

When we round up 45.55 to 2 decimal places, we get 45.56.
