Answer:

0 is the rational number

Step-by-step explanation:

Yes, 0 is the rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer.

Answer:

4?

Step-by-step explanation:

I dont think its right because i dont know how can it be four its just a guess :)

Answer:

a + b = 100

a - b = 6

2a = 106

2a/2 = 106/2

a = 53

53 + b = 100

53 + b - 53 = 100 - 53

b = 47

Answer:

Read down below :)

Step-by-step explanation:

Rather than taking it on and overthinking it the way everyone else does, do it the simple way, like this:

15/3 = 5, right? and 5, when multiplied by 4, becomes 20, right? So divide 4 by 3, and then take that number, and muliply it by 4.

Like this: (4 / 3) * 4, and then you know that 5 L of gas requires 1.33e L of oil. So, like 5*4 = 20, so is 1.33e *4, the amount of oil in 20 L. In all, the answer is 5.33e, or [tex]5 \frac{3}{5}[/tex] or whatever your answer might have to be

Answer:

a. $6 =  ($500 + $2q) / q

b. 125

Average cost =  ($500 + $2q) / q

($500 + $2x 125) / 125 = $6

Step-by-step explanation:

Average cost = total cost / quantity produced

total cost = fixed cost + variable cost

Fixed costs are costs that do not vary with output. e.g. the cost of the logo

Variable costs are costs that vary with production e.g. cost of printing and cutting

Variable cost = $2 x quantity of parking ticket sold

let q =  quantity of parking ticket sold

variable cost = 2q

$6 = ($500 + $2q) / q

to determine the number of parking ticket to be sold for average cost to be $6, take the following steps

Multiply both sides of the equation by q

6q = 500 + 2q

collect like terms

6q - 2q = 500

4q = 500

q = 125

125 tickets have to be sold for average cost to the $125

to justify the answer, replace 125 in the first equation to confirm if $6 would gotten as the average cost

($500 + $2q) / q

($500 + $2x 125) / 125 = $6

50-15

60-30

70-45

80-60

90-85

In 10 days Farah and Shirley will have the same amount of money

A linear equation is an alzebraic expression which has highest degree of one and contains only one variable.

In the given question farah saved 15$/day and Shirley saved 10$/day

Shirley started 5 days earlier so in 5 days she will save 10 x 5 = 50$

let assume days to be x.

So,

   10x + 50 = 15x

   5x = 50

    x = 10 .

Answer:

Step-by-step explanation:

i am assuming this is  (n+3)^6 if so

729+1458x+1215x^2+540x^3+135x^4+18x^5+x^6

the fifth term is 135x^4

The fifth term of the expression (n + 3)⁶ is 1,215n².

An expression that has been raised to any finite power can be expanded using the binomial theorem. A useful expansion technique with applications in probability, probability theory, and algebra is the binomial theorem.

The given expression is,

(n + 3)⁶.

To find the fifth term in the expression,

Use binomial expansion method,

[tex](x+y)^n = ^{n}C_0 x^nny^0 + ^nC_1 x^{n-1}y^1 + ^nC_2 x^{n-2} y^2 + ...[/tex]

Use the binomial formula for expression (n + 3)⁶,

[tex](n+3)^6 = ^6C_0n^63^0 + ^6C_1n^53^1 + ^6C_2n^43^2 +^6C_3n^33^3 + ^6C_4n^23^4 + ^6C_5n^13^5 + ^6C_6n^03^6[/tex]

The fifth term of the expression is [tex]^6C_4n^23^4[/tex].

The term [tex]^6C_4n^23^4[/tex] can be simplified as,

[tex]^6C_4n^23^4[/tex] = 15 x n² x 81 = 1215n².

The fifth term of the expression (n + 3)⁶ is 1,215n².

Answer:

The total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the  number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

Given:

Of the 50 flips, the coin landed on heads 30 times.

To find:

The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.

Solution:

We have,

Total number of trials = 50

Total number of heads = 30

The experimental probability of flipping heads is:

[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]

[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]

[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]

[tex]\text{Experimental probability}=0.6[/tex]

A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:

[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]

[tex]\text{Theoretical probability}=0.5[/tex]

Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.
