30 minutes. If a passenger train and a
freight train just left at the same time, how
long will it be before one of each train
departs at the same time again?
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.

Cost price of an item is Rs 600. If the selling price is Rs 780, then the profit percent is
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%

Suppose we want to choose 5 colors, without replacement, from 18 distinct colors.
(a) If the order of the choices does not matter, how many ways can this be done?
(b) If the order of the choices matters, how many ways can this be done?
Considering the definition of permutation and combination:
the number of ways of choosing 5 colors from 18 distinct colors (the order doesn't matter) is 8,568.the number of ways of choosing 5 colors from 18 distinct colors (the order of choices matters) is 1,028,160.Definition of PermutationPermutation 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:
take all the elements of a set.the elements of the set are not repeated.order matters.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.
Definition of combinationCombinations 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]
This caseIn this case, you know we want to choose 5 colors, without replacement, from 18 distinct colors. This is:
We want to choose 4 colors: n= 5The total number of distinct colors: m= 18(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.

4a + 8 - 2a - 3 = 45
Answer:
a=20
Step-by-step explanation:
4a+8-2a-3=45
-8 on both sides
4a-2a-3=37
+3 on both sides
4a-2a=40
2a=40
a=20
Answer:
a = 20
Step-by-step explanation:
Let's understand it quickly,
4a + 8 - 2a - 3 = 45
Gather the like terms on RHS and LHS,
4a - 2a = = 45 - 5
2a = 40
a = 40/2
a = 20

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.

A recipe for chocolate chip cookies with toffee bits and walnuts serves 8 people and needs 3 cups of flour. If Zachary wants to make the recipe for 14 people, how many cups of flour should he use?
I will mark you as the brainliest IF answered correctly.
Answer:
Im pretty sure it's 5.25 cups of flour
Step-by-step explanation:
so we know that it takes 3 cups for 8 people and we don't know the amount for 14 people so write it as a fraction and cross multipy
For the equation
8/3=14/x
The cross product is
8*x=3*14
Solving for x
x=3×14/8
and reducing
x=5.25

Step-by-step explanation:
Let U = { 14, 15, 16, 17, 18, 19, 20 },
A = { 16, 17, 18, 19 }.
Use the roster method to write the set A′.
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.

Antonio bought a box of cookies for $3.84.
If there are 24 cookies in the box, how much did Antonio pay per cookie?
Explain your thinking using 3-5 complete sentences.
Answer:
24 cookies in a box, and it costs 3.84. since the whole thing costs 3.84, to find the unit rate of each cookie, you need to divide the price by the amount of cookies. 3.84 divided by 24 is equal to 0.16. so the price per cookie would be 16 cents.
