Answer:

Profit percentage=30%

Step-by-step explanation:

The profit percentage=profit/cost price×100%

but we can calculate profit as=selling price-cost price

profit=Rs780-Rs600=Rs180

Now substitute the profit value into the formula

Profit percentage=Rs180/Rs600×100%=30%

C.P of an item= Rs.600

S.P of an item = Rs. 780

Profit = SP- CP

= Rs. 780- Rs.600

=Rs.180

Now, profit percent= profit÷ CP × 100%

= 180 ÷ 600 × 100%

=30%

Answer:

Help with what? You didn't post anything.

Step-by-step explanation:

Considering the definition of permutation and combination:

Permutation is placing elements in different positions. So, permutations of m elements in n positions are called the different ways in which the m elements can be arranged occupying only the n positions.

In other words, permutations (or Permutations without repetition) are ways of grouping elements of a set in which:

To obtain the total of ways in which m elements can be placed in n positions, the following expression is used:

[tex]mPn=\frac{m!}{(m-n)!}[/tex]

where "!" indicates the factorial of a positive integer, which is defined as the product of all natural numbers before or equal to it.

Combinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.

To calculate the number of combinations, the following formula is applied:

[tex]C=\frac{m!}{n!(m-n)!}[/tex]

In this case, you know we want to choose 5 colors, without replacement, from 18 distinct colors. This is:

(a) If the order of the choices is not taken into consideration, you use a combination as follow:

[tex]C=\frac{18!}{5!(18-5)!}[/tex]

Solving:

[tex]C=\frac{18!}{5!13!}[/tex]

C= 8,568

Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.

(b) If the order of the choices matters, you use a permutation as follow:

[tex]18P5=\frac{18!}{(18-5)!}[/tex]

Solving:

[tex]18P5=\frac{18!}{13!}[/tex]

18P5= 1,028,160

Finally, the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.

Complement of A set in roster form will be {14,15,20}.

U​ = { 14​, 15​, 16​, 17​, 18​, 19​, 20 ​},

A​ = { 16​, 17​, 18​, 19 ​}.

A'= {14,15,20}

A set is mathematically represented in a straightforward way using roster notation. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, a comma is used in a roster notation to indicate the separation of every two elements. A list of the elements of a set, each separated by a comma, enclosed in a set of curly brackets, can be used to describe the contents of the set. Roster form is the term for this method of setting forth a set.

Step-by-step explanation:

what is the question ?

check everything that applies to the angles 1 and 2 ?

in that case :

two angles are adjacent angles, when they share a vertex and side.

so, yes, adjacent angles is true

vertical angles are angles that are opposite of each other when two lines cross.

so, no, vertical angles is false.

two angles are complementary, when they are adjacent and have combined 90°.

so, yes, complementary angles is true.

2 angles are supplementary, when they are adjacent and have combined 180°.

so, no, supplementary angles is false.

a linear pair of angles is basically the same as supplementary angles.

they are formed when two lines intersect each other (at a single point). The angles at the intersection point are linear if they are adjacent to each other, and their sum is always equal to 180°.

so, no, linear pair is false.

When Passenger trains leave the station every 40 minutes and  Freight trains leave every 30 minutes, If  a passenger train and a freight train just left at the same time, then it will take 120 minutes for one of  each train departs at the same time again

Given,

The passenger trains leave the station every 40 minutes

Freight trains leave every 30 minutes

We have to find the LCM

Prime factorization

30=2×3×5

40=2×2×2×5

LCM(30,40)= 2×2×2×3×5=120

Hence, when Passenger trains leave the station every 40 minutes and  Freight trains leave every 30 minutes, If  a passenger train and a freight train just left at the same time, then it will take 120 minutes for one of  each train departs at the same time again.

Step-by-step explanation:

The equation can be expressed as the product of 5 and a number increased by 7 is equal to 10.

Linear equation are equations that has a leading degree of 1. The standard linear equation is given as y = mx + b

Given the expression 5x + 7 = 10

Subtract 7 from both sides to have:

5x+ 7 - 7 = 10 -7

5x = 10 - 7

5x = 3

5x - 3 = 0

5x = 3

x = 3/5

The equation can be expressed as the product of 5 and a number increased by 7 is equal to 10.
