At an assembly.180 students sit in 9 equal rows .how many students sit in each row

Answers

If there are 180 students sitting in 9 equal rows. The number of students sitting in each row will be 20.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, at an assembly.180 students sit in 9 equal rows.

We have to find the number of students sit in each row

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

The number of students sitting in each row is found as,

=180 / 9

=20

Thus, if there are 180 students sitting in 9 equal rows. The number of students sitting in each row will be 20.

If set D is not the empty set but is a subset of set E, then which of the following is true? D ∩ E = D D ∩ E = E D ∩ E = ∅

Answers

Answer:

D\cap E=D

Step-by-step explanation:

We are given that D is not empty set but D is a subset of set E.

We have to find the true statement.

D\neq \phi

D is  a subset of set E

Therefore,D\subset E\neq \phi

Intersection: It is the set of common  elements of two sets.

Therefore,D\cap E=D

Because E contains all elements of D .

Hence, Option A is true.

Answer:

D intersect E=D (the first one you have)

Step-by-step explanation:

D is a subset of E

That means all the elements in D are also in E

So the intersection of D and E is D.

The first thing you wrote is correct, that is, D intersect E=D is right

What is the domain of the function y=ln(12-4x/5)

Answers

Answer:

The domain of the function is  x<3                                

Step-by-step explanation:

Given : Function y=\ln ((12-4x)/(5))

To find : What is the domain of the function ?

Solution :

Domain is defined as the set of possible values which define the function.

We know that, log negative is not defined.

So, we will get the inequality  in the function.

\ln ((12-4x)/(5))>0

(12-4x)/(5)>0

12-4x>0

-4x>-12

x<3

Therefore, The domain of the function is  x<3

\ln x has a domain of x>0, so \ln\left(12-\frac{4x}5\right) has a domain of

12-\frac{4x}5>0\implies12>\frac{4x}5\implies x<15
