books are on sale for $4 each which graph shows the cost y of a given number of books​

Answer:

3rd choice

Step-by-step explanation:

the 3rd choice is the same as all of the others just in fraction form .you need to keep fraction form for the statement to still be true

Answer: 1st one

Step-by-step explanation: All you got to think about is think of the fraction if the x value is odd and the y value is odd, when you add them together you will get and odd number. :)

Answer:

23.9% = 47400

divide both sides by 23.9 to find 1%

1% = 1983.26359

now multiply by 100 to find total number of doctors

1983.26359 X 100

100% = 198326

Answer:

6+3b=x

Step-by-step explanation:

The total amount of money spend on crackers and cheese is given by the inequality 3b + 6 ≤ 15

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the amount spend on cheese be = $ 6

The number of boxes of crackers = b

The cost of one box of crackers = $ 3

So , the total amount for b box of crackers = 3b

The maximum amount of money that can be spend = $ 15

And , total amount of money spend on crackers and cheese is

3b + 6 ≤ 15

Subtracting 6 on both sides , we get

3b ≤ 9

Divide by 3 on both sides , we get

b ≤ 3 boxes

Therefore , the value of b is 3 boxes

Hence , the inequality is 3b + 6 ≤ 15

Mari spends $6 on cheese for a party she also plans to buy b boxes of crackers that cost $3 per box.Which inequality shows that Mari wants to spend at most $15 on cheese and crackers for the party?

Answer: The total number of student in the school  = 240.

Step-by-step explanation:

Let x be the total number of students in the school.

Given: 35% of the students at Charles drew middle school are 6th graders.

i.e. Number of sixth graders = 35% of x = 0.35x   [35% = 0.35]

Since there are 84 sixth graders in the school,

So  [tex]0.35x=84[/tex]

Divide both sides by 0.35, we get

[tex]x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240[/tex]

Hence, the total number of student in the school  = 240.

Answer:

There are 102 children

Step-by-step explanation:

Let us solve the question

∵ There are 272 people in an audience

∴ The total number of people = 272

∵ The ratio of adults to children is 5: 3

→ Find the sum of the two parts of the ratio

∴ The sum of the parts of the ratio = 5 + 3 = 8

→ By using the ratio method

→  Adults:  Children:  People

→  5        :   3            :  8

→  A        :   C           :  272

→ By using the cross multiplication

∵ C × 8 = 3 × 272

∴ 8C = 816

→ Divide both sides by 8

∴ C = 102

∵ C represents the number of children

∴ There are 102 children

Step-by-step explanation:

Answer:

Mean = 35

Median = 0.5(n + 1)th term

Median = 0.5(9) = 4.5th term

(30 + 34) /2 = 32

Mode = 30 ( most frequent)

Range = (51 - 20) = 31

Mean = 72

Median = 0.5(n + 1)th term

Median = 0.5(9) = 4.5th term

4th + 5term = (72 + 77) /2 = 74.5

Mode = 72 ( most frequent)

Range = (90 - 48) = 42

Step-by-step explanation:

Given :

1.)

Data: 30 , 40 , 51 , 30 , 34 , 20, 30, 45

Rearranged data : 20, 30, 30, 30, 34, 40, 45, 51

Mean = ΣX / n = 280 / 8

Mean = 35

Median = 0.5(n + 1)th term

Median = 0.5(9) = 4.5th term

(30 + 34) /2 = 32

Mode = 30 ( most frequent)

Range = (51 - 20) = 31

2.)

90 , 72 , 48 , 84 , 77 , 72, 50, 83

Rearranged data : 48, 50, 72, 72, 77, 83, 84, 90

Mean (m) = ΣX / n = 576 / 8

Mean = 72

Median = 0.5(n + 1)th term

Median = 0.5(9) = 4.5th term

4th + 5term = (72 + 77) /2 = 74.5

Mode = 72 ( most frequent)

Range = (90 - 48) = 42

Answer:

x=12 but who knows maybe

Step-by-step explanation:

if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.

Answer:

12 ft ^3

Step-by-step explanation:

Volume of the box would be width x length x height

If the box of an area already covers four feet (width times length) we just need to multiply by the height:

4*3 =12 cubic feet

Step-by-step explanation:

the process of finding out the variable value that makes the equation true is called 'solving' the equation. An equation is a statement that two quantities are equivalent. For exp/example:. x + 1 = 4 mean that when we add 1 to the unknown value, 'x', the answer is equal to 4 .

Answer:

10

Step-by-step explanation:

Answer:

Suppose that we have a converging series like:

(a₁ + a₂ + a₃ + ... ) = A

or

∑aₙ = A

So this series converges to the value A.

Now, let's multiply all the coefficients by a real number c, different than zero, then the sum is:

(c*a₁ + c*a₂ + c*a₃ + ...)

now we can take the common factor c out, to get:

c*(a₁ + a₂ + a₃ + ...)

And the thing inside the parentheses is equal to A, then we have:

c*(a₁ + a₂ + a₃ + ...) = c*A

So the series still converges for any value of c.

Now, suppose that this series diverges (to minus infinity or infinity)

Then we have:

(b₁ + b₂ + b₃ + ...) = ∞

Same as before, we multiply all the terms by the same number c:

(c*b₁ + c*b₂ + c*b₃ + ...)

again, we take the common factor out:

c*(b₁ + b₂ + b₃ + ...)

And same as before, we get:

c*(b₁ + b₂ + b₃ + ...) = c*∞

and c*∞ is still equal to ∞ (or -∞ if c is negative), so the series still diverges.
