HELPPPPPPPPPP PLEASE WILL MARK BRAINLIEST!!!!!!!! Assuming that a soap bubble is a perfect sphere, what is the diameter of a bubble containing 1,000 cm3 of air? Round to the nearest tenth. A. 6.2 cm B. 7.5 cm C. 12.4 cm D. 15.0 cm

Answers

Answer 1

Answer: 12.4 cm

Step-by-step explanation:

Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.

[tex]V=\frac{4}{3} \pi r^3[/tex]

[tex]1000=\frac{4}{3} \pi r^3[/tex]

[tex]750=\pi r^3[/tex]

[tex]r^3=238.7324146[/tex]

[tex]r=6.2[/tex]

Now that we have r, we multiply it by 2 to get diameter.

2×6.2=12.4

Answer 2

Answer:

C

Step-by-step explanation:

V=4/3πr^3

1000=4/3πr^3

1000=(4/3(3.141593))(r^3)

Step 1: Subtract 4.18879r^3 from both sides.

1000−4.18879r3=4.18879r^3−4.18879r^3

−4.18879r^3+1000=0

Step 2: Subtract 1000 from both sides.

−4.18879r^3+1000−1000=0−1000

−4.18879r^3=−1000

Step 3: Divide both sides by -4.18879.

−4.18879^3 /−4.18879  =  −1000 /−4.18879

r^3=238.732415

Step 4: Take cube root.

r=(238.732415)^1/3

r=6.203505

Use the formula V=Bn to find the volume of the prism.

Answers

Answer:

the formula is V=BH

Step-by-step explanation:

if the prism is rectangular prism : it has three dimensions then V=length * height * width

V= L*H*W or V= base*H

or V=BH

in your question it does not show V=BH maybe it is misprint

The volume of the prism is V = Bh , where B is the base area and h is the height of the prism

What is the volume of a prism?

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

Identify the shape of the base of the prism: The base of the prism can be any polygon, such as a triangle, rectangle, or hexagon. It is important to identify the shape of the base because the formula for calculating the area of the base will depend on the shape.

Calculate the area of the base: Once the shape of the base has been identified, calculate the area of the base using the appropriate formula. For example, if the base is a rectangle, the area would be calculated as length x width.

Multiply the area of the base by the height of the prism: Once the area of the base has been calculated, multiply it by the height of the prism to get the volume. The height is the perpendicular distance between the two parallel bases of the prism.

Hence , by following these three steps, you can calculate the volume of a prism regardless of its shape, as long as you can identify the shape of the base and calculate its area.

Step-by-step explanation:

Let's solve your equation step-by-step.

[tex]x^2+8x=7[/tex]

The coefficient of 8x is 8. Let b=8.

Then we need to add (b/2)^2=16 to both sides to complete the square.

Add 16 to both sides

x^2+8x+16 = 7+16

x^2 + 8x+ 16= 23

Which statement is true? A. A sample statistic can never be equal to the population parameter. B. Point estimates are defined for both samples and populations. C. To calculate a sample proportion, we need to know the population size. D. To calculate a point estimate, we need to know the sample size.

Answers

Answer: A) A sample statistic can never be equal to the population parameter.

Step-by-step explanation:

The statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.

The following statements should not be considered:

The statistic of the sample should be equal to the parameter of the population as the statistic represent the attribute of the sample and the parameter represent the parameter of the population. Also, each and every sample should have an equivalent chance of using it. The estimation of the point does not define the sample & population as the estimation of the point should be predicted for the parameter of the population.For determining the point estimate, the sample size does not need as the population is required.

Therefore we can conclude that the statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.

Step-by-step explanation:

Step-by-step explanation:

You need to choose 1 out 14 for the first position, then 1 out of the 13 left  for the second position, then 1 out the 12 left for the third position.

That gives 14 * 13 * 12 = 2184.

If order mattered, that would be the answer, but in this case, since order does not matter, the 3 positions can be filled in 3 * 2 * 1 ways = 6 ways.

Step-by-step explanation:

Step(i):-

Given f(x)   =  3 x - 4

         g (x)  = −x²+2 x−5

        h (x)  = 2 x² + 1

         j (x)    = 6 x + 2 - 8 x

        K (x)   = 3 x² - x + 7

Step(ii):-

( f h ) (x) = f ( h (x)) = f ( 2 x² + 1 )

                            =  3 (2 x² + 1 ) - 4

                            =  3 ((2 x² ) + 3 - 4

                           =   6 x² - 1

Final answer:-

Find the central angle of a sector of a circle of the area of the sector and the area of the circle are in the proportion of 3:5

Answers

Answer:

[tex]\theta = 216[/tex]

Step-by-step explanation:

Given

Area of Sector : Area of Circle = 3 : 5

Required

Determine the central angle

The question implies that

[tex]\frac{Area_{sector}}{Area_{circle}} = \frac{3}{5}[/tex]

Multiply both sides by 5

[tex]5 * \frac{Area_{sector}}{Area_{circle}} = \frac{3}{5} * 5[/tex]

[tex]5 * \frac{Area_{sector}}{Area_{circle}} = 3[/tex]

Multiply both sides by Area{circle}

[tex]5 * \frac{Area_{sector}}{Area_{circle}} * Area_{circle} = 3 * Area_{circle}[/tex]

[tex]5 * {Area_{sector} = 3 * Area_{circle}[/tex]

Substitute the areas of sector and circle with their respective formulas;

[tex]Area_{sector} =\frac{\theta}{360} * \pi r^2[/tex]

[tex]Area_{circle} = \pi r^2[/tex]

So, we have

[tex]5 * \frac{\theta}{360} * \pi r^2 = 3 * \pi r^2[/tex]

Divide both sides by [tex]\pi r^2[/tex]

[tex]5 * \frac{\theta}{360} * \frac{ \pi r^2}{\pi r^2} = 3 * \frac{\pi r^2}{\pi r^2}[/tex]

[tex]5 * \frac{\theta}{360} = 3[/tex]

Multiply both sides by 360

[tex]360 * 5 * \frac{\theta}{360} = 3 * 360[/tex]

[tex]5 * \theta = 3 * 360[/tex]

Divide both sides by 5

[tex]\frac{5 * \theta}{5} = \frac{3 * 360}{5}[/tex]

[tex]\theta = \frac{3 * 360}{5}[/tex]

[tex]\theta = \frac{1080}{5}[/tex]

[tex]\theta = 216[/tex]

Hence, the central angle is 216 degrees

PLSS HELP SOON Is the sequence arithmetic? (Yes or no) If yes, please also give its common difference. 14) -2.8, -2.2, -1.6, -1.0

Answers

Answer:

The sequence is an arithmetic sequence.

Common difference = 0.6

Step-by-step explanation:

Given

-2.8, -2.2, -1.6, -1.0

Required

State if it's an arithmetic progression

Also state its common difference

To know if a sequence is arithmetic or not, we simply check for common difference

Common difference is calculated by subtracting a lower term with its immediate higher time;

In other words

[tex]Common difference = T_2 - T_1 = T_3 - T_2 = T_4 - T_3 = ......[/tex]

Where T represent Term and the number represent their positions;

So, from the given above

[tex]T_1 = -2.8\\T_2 = -2.2\\T_3 = -1.6\\T_4 = -1.0[/tex]

Calculating [tex]T_2 - T_1[/tex]

[tex]T2 - T1 = -2.2 - (-2.8)\\T2 - T1 = -2.2 + 2.8\\T2 - T1 = 0.6\\[/tex]

Calculating [tex]T_3 - T_2[/tex]

[tex]T_3 - T_2 = -1.6 - (-2.2)\\T_3 - T_2 = -1.6 + 2.2\\T_3 - T_2 = 0.6[/tex]

Calculating [tex]T_4 - T_3[/tex]

[tex]T_4 - T_3 = -1.0 - (-1.6)\\T_4 - T_3 = -1.0 + 1.6\\T_4 - T_3 = 0.6[/tex]

Notice that all the above workings gave the same result;

This shows that the sequence is an arithmetic sequence.

The result of each workings above is the common difference

Common difference = 0.6
