The radius of the Earth, approximately equal to the radius of the globe raised to the 10th power, is 250,562,113.2 inches.

First, solve for the radius of the desktop world globe using the formula for the volume of a sphere given by:

V = 4/3 π r^3

If the desktop world globe has a volume of about 1386 cubic inches, then

1386 cubic inches = 4/3 π r^3

r = 6.916582163 inches

Next, solving for the radius of the Earth if it is approximately equal to the radius of the globe raised to the 10th power.

Exponent, or power, is the small number written at the upper right of a constant or variable that tells how many times that constant or variable should be multiplied to itself.

If the radius of the Earth if it is approximately equal to the radius of the globe raised to the 10th power, then

If the baker has a total of 1/2 bags of flour, the total weight of the bags of flour is 1.625

What is the weight of a bag of flour in pounds?

The fact that each bag of flour weighs 3 and 1/4 pounds means that each bag of flour is 3.25 pounds, in essence, the total weight of flour that the baker has can be determined as the weight of a bag of flour multiplied by the total of 1/2 bags of flour.

total weight of bags of flour=weight of a bag of flour*total weight of baker's flour

weight of a bag of flour=3.25 pounds

Answer:

624,062.58 is your answer :)

Step-by-step explanation:

the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

We are given the two equations:

y = - x - 4

- 7 x + 8 y = 16

We need to solve these equations by substitution.

We will substitute the equation 1 in the equation 2 to get the values of x and y:

- 7 x + 8 y = 16

- 7 x + 8 (- x - 4) = 16

- 7 x - 8 x - 32 = 16

- 15 x = 16 + 32

- 15 x = 48

Divide both sides by - 15, we get that:

x = 48 / - 15

x = - 16 / 5

y = - x - 4

Put the value of x

y = 16 / 5 - 4

y = 16 - 20  / 5

Subtract to get the value:

y = - 4 / 5

Therefore, we get that, the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

For each individual spin, there  are two possible outcomes:

- There is a 1 in 38 chance of winning $175.

- There is a 37 in 38 chance of losing $5.

The expected value for each spin is the sum of the products of each outcome by their respective probability.

expected value =E1×P1 + E2×p2

Answer: Yes, all horizontal lines have slope of 0

Reason:

Recall that slope = rise/run

The rise tells us how far to go up or down. A horizontal line does neither. There's no change in y value.

So we have slope = rise/run = 0/run = 0, where "run" is any positive number you want. The run is how far to the right we go each time moving up or down.

Answer: Yes

Step-by-step explanation:

When you have a horizontal line it is flat and has no slope at all

The solution to the given equation -1 = -1 + (p/8) is p = 0.

Given the data in the question;

Solve for p to determine the solution to the equation.

-1 = -1 + (p/8)

Rewrite the equation as;

-1 + (p/8) = -1

Next, move all terms containing p to the left side and all constants to the right side of the equation.

-1 + (p/8) = -1

(p/8) = -1 + 1

Add -1 and 1

p/8 = -1 + 1

p/8 = 0

p = 0 × 8

p = 0

The solution to the given equation -1 = -1 + (p/8) is p = 0.

The length of the diagonal (D) of this rectangular prism is equal to 9.5 feet.

Pythagorean theorem can be defined as a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.

In order to determine the length of the diagonal (D) of this rectangular prism, we would first of all determine the diagonal of the base by applying Pythagorean theorem:

d² = l² + b²

d² = 4² + 7²

d² = 16 + 49

d² = 65

d = √65

Now, we can determine the length of the diagonal (D) of this rectangular prism:

D² = d² + h²

D² = √65² + 5²

D² = 65 + 25

D² = 90

D = √90

Diagonal, D = 9.5 feet.

Therefore, the length of the diagonal (D) of this rectangular prism is equal to 9.5 feet.

All i did was divided 3 by 12

Both 3 is an extraneous solution.

We have the equation x - 6 = [tex]\sqrt{3x}[/tex]

To find the value of x we need to square on both side of the equation

[tex](x-6)^{2}[/tex] = [tex](\sqrt3{x} )^{2}[/tex]

[tex]x^{2}[/tex] - 12x + 36 = 3x

[tex]x^{2}[/tex] -15x + 36 = 0

[tex]x^{2}[/tex] - 12x - 3x + 36 = 0

x ( x- 12 ) - 3( x - 12) = 0

(x -12 ) ( x - 3) = 0

Therefore we get x = 12 , 3

Now we will put both the value of x in the equation

x - 6 = [tex]\sqrt{3x}[/tex]

Let put 12 first

12 - 6 = [tex]\sqrt{3 * 12}[/tex]

6 = 6
