Consider the set A, of all integers from 1 to 10 inclusive (that means the 1 and the 10 are included in this set) Give a set B t
Mademuasel [1]

Answer:

C^{I} = {2, 4, 10}

Step-by-step explanation:

A set is a collection of objects called elements. These element are refered to as members of the set.

Set A contains all integers from 1 to 10 inclusive;

A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

A subset of a given set implies that every element of the subset are also elements of the given set. Set B is a subset of A;

B = {1, 3, 5, 6, 7, 8, 9}

Complement of a given set refers to elements not in the general set. Set C is the complement of B;

C^{I} = {2, 4, 10}

Solve for a. 7a-2b=5a+b
velikii [3]
8.5b.
7a= 5a +3b
-5a -5a
2a = 3b
/2
a= 1.5b
Solve by substitution and you get;
8.5b=8.5b
Because of the lack of constants in the equation there isn't a definite answer.

A sphere of radius 2.3 cm fits exactly in a cylinder with the same radius. Complete the steps to determine the volume of space i
VARVARA [1.3K]

Answer:

Part 1) The volume of the cylinder is 76.41\ cm^{3}

Part 2) The volume of the sphere is 50.94\ cm^{3}

Part 3) Determine <em>the difference</em> of the volumes to find the leftover space

Part 4) The volume of space in the cylinder that is not being taken up by the sphere is about 25.47\ cm^{3}

Step-by-step explanation:

step 1

Calculate the volume of the cylinder

V=\pi r^{2}h

we have

r=2.3\ cm

h=2.3*2=4.6\ cm -----> the height is the diameter of the sphere

substitute the values

V=(3.14)(2.3)^{2}(4.6)=76.41\ cm^{3}

step 2

Calculate the volume of the sphere

V=\frac{4}{3}\pi r^{3}

we have

r=2.3\ cm

substitute the values

V=\frac{4}{3}(3.14)(2.3)^{3}=50.94\ cm^{3}

step 3

Determine the difference of the volumes to find the leftover space

76.41\ cm^{3}-50.94\ cm^{3}=25.47\ cm^{3}

therefore

The volume of space in the cylinder that is not being taken up by the sphere is about 25.47\ cm^{3}
