Answer:

(D) 4/3π(8.06×10^16)

Step-by-step explanation:

The volume of a sphere is given by the formula ...

V = 4/3πr³

Using the given value for the radius, the volume of the Sun is ...

V = 4/3π(4.23×10^5 mi)³ ≈ 4/3π(8.06×10^16) mi³

P1. if your school makes $0.72 profit on every 6 raffle tickets sold, how much will it make when it sells the 11th ticket

Ahat [919]

Answer:

Part 1 = $1.32

Step-by-step explanation:

.72 divided by 6 is 12. So they make 12 cents per ticket, so that means you would have to do 12 times 11 and that should get you 132 cents and that is equivalent to $1.32.

Solve x + 3y = 9 3x – 3y = -13 (1 point)

zavuch27 [327]

Answer:

(-1, 10/3)

x = -1

y = 10/3

Step-by-step explanation:

To solve a system, one of the methods you can use is elimination. To use elimination, you need a variable to have the same coefficient in BOTH equations. Since both equations have "3y", with the same coefficient (3), we can use this method.

We want to eliminate a variable by cancelling it out. Since positive 3y PLUS negative 3y is 0, the variable in eliminated. ADD each of the terms in the equations together.

. x + 3y = 9

+ 3x – 3y = -13

. 4x – 0y = -4 3y - 3y = 0

. 4x = -4 Divide both sides by 4 to isolate 'x'

. x = -1 Solved for the x-coordinate

Since we know one variable, 'x', we can easily find the other, 'y'. Substitute 'x' with -1 in any of the equations. Then, isolate 'x'.

x + 3y = 9

(-1) + 3y = 9

-1 + 1 + 3y = 9 + 1 Add 1 to both sides to cancel out left side.

3y = 9 + 1 Add on the right side (9 + 1 = 10)

3y = 10 Divide both sides by 3 to isolate 'y'

y = 10/3 Solved for the y-coordinate

Put the 'x' and 'y' coordinates together in an ordered pair, which you write as (x, y).

The solution to the system is (-1, 10/3).

What number must you add to complete the square?

eimsori [14]

Answer:

Step-by-step explanation:

x^2 + 12 x = 40

To complete the square, take the coefficient of the x term

Divide by 2

12/2 = 6

Square it

6^2 = 36

Add 36 to each side

Graph the quadratic function F(x)=3x^2+6x-24

Oliga [24]

For this case we have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)
Answer:
See attached image to see graph of the function
