What would 20-(2+1)-6÷3 be

Will has 24 quarters from 2005, which means the total value of these quarters equals to $6.

Will has 40 state quarters in total. If 3/5 of them are from 2005, this simply means that you need to find 3/5 of 40. So, we multiply 40 by 3/5:
40 * 3/5 = 24.

So, Will has 24 quarters from the year 2005.

Next, to find the value of these quarters, remember that each quarter is worth 25 cents (or $0.25 in dollar form). Therefore, we multiply the number of quarters (24) by the value of each quarter (.25):
24 * 0.25 = $6.

So, the total value of the quarters from 2005 is $6.

Answer:

I assume your asking who's is better and why?

Step-by-step explanation:

Ralph has stated that for 1 shirt it will cost

$7.50 + $10 shipping= $17.50

Frank says it's $10 a shirt no shipping

if you work out the cost of Ralph's up to 5 shirts using the equation

($7.50 x number of shirts ) + $10 shipping

with each equation replace number of shirts with the number 1,2,3,4 and 5

1 shirt will cost you $17.50

2 shirts will cost you $25.00

3 shirts will cost you $32.50

4 shirts will cost you $40.00

5 shirts will cost you $47.50

at Frank's shop

1 shirt will cost you $10

2 shirts will cost you $20

3 shirts will cost you $30

4 shirts will cost you $40

5 shirts will cost you $50

Frank's is better to buy no more than 4 shirts from as he's cheaper up to 4 shirts.

Ralph is cheaper for bigger orders with 5 or more shirts in them

The question deals with the comparison of the costs of buying T-shirts from Ralph’s company versus Frank’s company. The cost differs based on the number of T-shirts purchased and the associated shipping fees.

The question is asking for a comparison between the two companies selling T-shirts and the associated costs. Ralph's company sells T-shirts for $7.50 each with an additional flat rate of $10 for shipping. In contrast, Frank's company sells T-shirts at a slightly higher price of $10 each but does not charge any shipping fees.

For example: If a customer wants to buy one T-shirt from each company, from Ralph’s company it would cost $7.50 (T-shirt price) + $10 (shipping fee) = $17.50. From Frank’s, it would cost $10 (T-shirt price) since shipping is free. So the cost would be different in both cases. However, if the customer opts to buy multiple t-shirts, the total cost might change depending on the number of t-shirts they decide to buy because of the fixed shipping cost on Ralph's side.

Answer:

To find the probability that both friends randomly select a romance book one after the other, we can use the concept of conditional probability.

Let's denote the events:

- Event A: First friend selects a romance book.

- Event B: Second friend selects a romance book.

Given that there are 4 romance books left and a total of 7 books left (3 mystery + 4 romance), the probability of Event A happening for the first friend is:

\[ P(A) = \frac{4}{7} \]

After the first friend selects a romance book, there are now 3 romance books left out of a total of 6 books remaining (since one book has been chosen). So, the probability of Event B happening for the second friend, given that the first friend selected a romance book, is:

\[ P(B|A) = \frac{3}{6} = \frac{1}{2} \]

Now, to find the probability of both events happening, we multiply their probabilities:

\[ P(A \text{ and } B) = P(A) \times P(B|A) \]

\[ P(A \text{ and } B) = \frac{4}{7} \times \frac{1}{2} \]

\[ P(A \text{ and } B) = \frac{4}{14} \]

\[ P(A \text{ and } B) = \frac{2}{7} \]

So, the probability that both friends randomly select a romance book one after the other is \( \frac{2}{7} \).

Answer: f(x) = |x|

Step-by-step explanation:

A function is even if for every real N, f(N) = f(-N)

As you know, the module of a function always returns the positive value of a number, so I-3I = 3 = I3I (and that for every number)

So the function f(x) = IxI is an even function.

Functions with odd powers can not be even functions, so the second and tird options are discarded.

the fourth functions seems to be:

f(x) =∛x = (x)1/3 which is not even, because if x = 1, f(1) = 1, and if x=-1, f(-1) = -1

In the given functions, an even function is [tex]f(x)=|x|[/tex]. Therefore, the correct answer is option A.

A function's even, odd, or neither properties can be expressed algebraically or graphically in a variety of ways. If a function's graph remains unchanged when reflected in the y-axis, it is said to be an even function. Consider a function f(x) that is considered an even function if f(-x) equals f(x).

1) [tex]f(x)=|x|[/tex]

Let [tex]x = -3[/tex], we get

[tex]f(-3)=|-3|[/tex]

[tex]f(-3)=3[/tex]

[tex]f(-x)= f(x)[/tex]

2) [tex]f(x)=x^3-1[/tex]

Let [tex]x = -1[/tex], we get

[tex]f(-1)=(-1)^3-1[/tex]

[tex]f(-1)=-1-1[/tex]

[tex]f(-1)=-2[/tex]

[tex]f(-x)\neq f(x)[/tex]

3) [tex]f(x)=-3x[/tex]

Let [tex]x = -1[/tex], we get

[tex]f(-1)=-3(-1)[/tex]

[tex]f(-1)=3[/tex]

[tex]f(-x)\neq f(x)[/tex]

4) [tex]f(x)=\sqrt[3]{x}[/tex]

Let [tex]x = -1[/tex], we get

[tex]f(-1)=\sqrt[3]{(-1)}[/tex]

[tex]f(-x)\neq f(x)[/tex]

Therefore, the correct answer is option A.

A cube is a prism whose sides all have the same length. So the dimension of this cube will be given by one of its sides. For any object that is submerged in water, the volume of the displacement liquid equals the volume of the object.

[tex]For \ any \ cube \ the \ volume \ in \ terms \ of \ one \ side \ (s) \ is: \\ \\ V=s^3[/tex]

Suppose the volume of the tank when full is [tex]16m^3[/tex], so if it is 5/8 filled with water, then:

Answer:

He have 17 CDs on Monday.

Step-by-step explanation:

Given:

On Tuesday James bought seven CDs. On Wednesday half of all the CDs that he had were destroyed. On Thursday he had 12 left.

Now, to find the CDs he have on Monday.

Let the CDs he have on Monday be [tex]x.[/tex]

So, on Tuesday as James bought 7 CDs:

[tex]x+7.[/tex]

Now, on Wednesday half of all the CDs that he had were destroyed:

[tex]\frac{x+7}{2}[/tex]

As, given on Thursday he had left CDs = 12.

According to question:

[tex]\frac{x+7}{2}[/tex] [tex]=12[/tex]

Multiplying both sides by 2 we get:

[tex]x+7=24[/tex]

Subtracting both sides by 7 we get:

Step-by-step explanation:

4x2 + 7x - 5 subtracted from

9x2 -2x + 3

8 + 7x - 5

18 - 2x + 3

(8-18) (+7x - -2x) (-5 - +3)

-10 ( +7x +2x) (-5-3)

-10 + 9x -8

The result when 4x2 + 7x − 5 is subtracted from 9x2 − 2x + 3 is found by adding the additive inverse of each term in the polynomial being subtracted. Result is: 5x2 - 9x + 8.

Subtraction of Polynomials:

To find the result when 4x2 + 7x − 5 is subtracted from 9x2 − 2x + 3, first remember that subtraction of polynomials is equivalent to adding the additive inverse of each term in the polynomial being subtracted.

So, 4x2 + 7x − 5 becomes -4x2 - 7x + 5. We then add this to 9x2 − 2x + 3 term by term.

The final result is: (9x2 + -4x2) + (-2x - 7x) + (3 + 5) = 5x2 - 9x + 8

You have to find a common denominator, so you would multiply 3 from the 1/3 by 4 which gets you twelve. And bc you multiplied the 3 you have to multiple the 1 so 1/3 would be 4/12. You would then multiply 4 by 3 and get 12. Then do the same to the one on top. So 1/4 would be 3/12. You then add 3 and 4 and get 7. That’s the numerator, the denominator stays 12.

The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today ⇒ A

Step-by-step explanation:

The given is:

We need to find which equation will help Teagan to determine how much he has to sell today

Assume that he has to sell by $x today

∵ The store pays $150 per day plus a commission of 15%

   of their sales

∵ Teagan's total sales = x

- Multiply 15% by x, then add the product by 150

∴ Teagan makes = 15% × x + 150

∵ 15% × x = [tex]\frac{15}{100}[/tex] × x = 0.15 x

∴ Teagan makes = 0.15 x + 150

∵ Teagan wants to make at least $450 today

- At least means ≥

∴ Teagan makes ≥ 450

- Substitute Teagan makes by 0.15 x + 150

∴ 0.15 x + 150 ≥ 450

The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today

To determine what percent 225 is of 150, the calculation (225 / 150) × 100% is used, resulting in 225 being 150% of 150.

To find what percent of 150 is 225, we can use the formula for calculating percents:

Percentage = (Part / Whole) × 100%

Where 'Part' is 225 and 'Whole' is 150. Now, let's calculate:

Percentage = (225 / 150) × 100%

Percentage = 1.5 × 100%

Percentage = 150%. So, 225 is 150% of 150.

The expression 64-16 simplifies to 48, and does not need the distributive property for simplification as it is a straightforward subtraction.

Explanation:

The question is asking to use the distributive property to simplify the expression 64-16. While this expression doesn't necessarily require the distributive property as it's a simple subtraction, sometimes in mathematics we leverage distributive properties or other algebraic rules to simplify or reorganize expressions. However, if we have a closer look at the provided reference information, none of it relates directly to the expression 64-16, which simplifies to 48. Therefore, there's no need to apply the distributive property here; the expression is already in its simplest form.

Final answer:

To find the number of cookies Hans baked on the second day, we solve the equation x + 2x + x/2 = 224, where x is the number of cookies baked on the first day. Solving this, we find x=64, meaning he baked 128 cookies on the second day.

Explanation:

The question involves solving a problem about Hans, who spent three days baking a total of 224 cookies. On the second day, he baked twice as many cookies as on the first day, and on the third day, he baked half as many as on the first day. To find how many cookies he baked on the second day, let's denote the number of cookies baked on the first day as x.

On the second day, he baked 2x cookies.

On the third day, he baked x/2 cookies.

Adding these together: x + 2x + x/2 = 224.

Combining like terms, we get 3.5x = 224.

Dividing both sides by 3.5 gives x = 64.

Therefore, he baked 2x = 2*64 = 128 cookies on the second day.
