The average weight of 3 books is
3/gm, one book weighs 3'/«gm
and the second 5/2gm. What is the
weight of the third?​

Answers

Answer 1

The weight of the third book is approximately 5.33 grams.

How to calculate the value

According to the given information:

The average weight of the 3 books is 3 grams.

To find the average weight, we sum up the weights of all the books and divide by the total number of books:

(1/3 + 5/2 + x) / 3 = 3

Now we can solve this equation to find the weight of the third book:

(1/3 + 5/2 + x) = 3 * 3

(1/3 + 5/2 + x) = 9

(1 + 15 + 6x) / 6 = 9

(22 + 6x) / 6 = 9

22 + 6x = 54

6x = 54 - 22

6x = 32

x = 32 / 6

x ≈ 5.33

Therefore, the weight of the third book is approximately 5.33 grams.

Area of a cylinder = area of circle x length

r = 8/2 = 4

[tex]4^{2}[/tex]π x 3 = 48π = 150.7964474

Answer:

37.68ft³

Step-by-step explanation:

So the formula for the volume of a cylinder is base x height our height is 3 but we have to find the area of the base:

the formula is: radius² x 3.14 (pi)

so we find the radius by dividing the diameter by 2: 8 ÷ 2 = 4

4 x 3.14 = 12.56

So the area of the base is 12.56ft²

now we plug that into our equation:

12.56 x 3 = 37.68

So the volume of the cylinder is 37.68ft³

hope this helps:)

Answer:

r = 16 cm ; l = 34 cm ; LA = 544π cm^2 ; SA = 800π cm^2

Step-by-step explanation:

The volume of the cone can be find with this formula

V = (base area x height)/3

thanks to this formula we can find the base surface

base surface = (V x 3)/height

base surface = (2560π x 3)/30 = 256π cm^2

the formula of the base surface is

base surface = radius^2 x π

so we can find the radius in this way:

radius = √base surface/π

radius = √256π/π = 16 cm

slant height = [tex]\sqrt{radius^2 + height^2}[/tex]

[tex]\sqrt{16^2 + 30^2} =\sqrt{256 + 900} = \sqrt{1156} = 34[/tex] cm

lateral surface = radius x slant height x π = 16 x 34 x π = 544π cm^2

surface area = base area + lateral surface = 256π + 544π =800π cm^2

A cone has the same radius and height as a cylinder which has greater volume the cone or the cylinder

Answers

Answer:

The cylinder has the great volume

Step-by-step explanation:

The volume of a cone = (h/3)πr²

The volume of a cylinder = hπr²

The only difference is that h is divided by 3 for the volume of a cone, making the total volume of a cone smaller than the volume of a cylinder with the same radius and height.

Solution :

Total amount to be targeted by selling of popcorns in the movie theatre is 550,000.

A viable solution is one which has a definite meaning or definite solution to the question in context whereas a non viable solution does not have a definite relevant solution to the question.

In the context,

The point (4,6) is a non viable solution as it does not satisfy 1st inequality and only satisfies the second inequality.

The point (6,5) is a viable solution as it satisfies both the inequalities.

Answers

Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. From this definition,

For sample 1, Every fifth person who enters Little Casesars Arena for a Red Wings game. This is not biased because no person is more likely to be selected than another

For sample 2, Every tenth name in the phone. This is also not biased

because no person is more likely to be selected than another
