How are the following three expressions different from each other, if indeed they are? do not just state the value of each but explain what may be the same or different. Be as specific as you can be in your response.
1.(-2)^2
2.-2^2
3. -(2)^2

Answers

Answer 1

Answer:

Below.

Step-by-step explanation:

Number is different to the other 2. Its value is +4 because negative 2 squared = + 4.

The other 2 have negative values and -2 = -(2) so they have the same value, -4.

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3

Answers

Answer:

Step-by-step explanation:

1/4 because all equal 24 together

and so

12 is half so pulling a club would be 1/2

6 is a fourth so pulling a diamond or heart would be 1/4

because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club

6=cards

2=diamonds and hearts

The probability of drawing a heart from the pile of 52 cards is 0.25.

The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.

We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.

As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.

Therefore, the total number of outcomes = 6+12+6= 24

and number of favorable outcomes = 6

Now, the probability of an event = 6/24

= 1/4

= 0.25

Therefore, the probability of drawing a heart is 0.25.

Answers

The value of A/B is given as follows:

A/B = -2.

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

A theater company has raised $810.75 by selling 15 floor seat tickets. Each ticket costs the same.

Part A: Write an equation with a variable that can be solved to correctly find the price of each ticket. Explain how you created this equation. (5 points)

Part B: Solve your equation in Part A to find the price of each floor seat ticket. How do you know your solution is correct? (5 points)

Answers

Part A:
Let's assume the price of each floor seat ticket is represented by the variable 'x'.

Since the theater company has raised $810.75 by selling 15 floor seat tickets, we can create an equation using the concept of total revenue. The total revenue is calculated by multiplying the price of each ticket by the number of tickets sold.

Therefore, the equation can be written as:

15x = 810.75

In this equation, '15x' represents the total revenue from selling 15 tickets at the price of 'x' per ticket, and '810.75' represents the total amount of money raised.

Part B:
To solve the equation 15x = 810.75, we need to isolate the variable 'x' on one side of the equation.

Dividing both sides of the equation by 15, we have:

x = 810.75 / 15

Evaluating the division, we find:

x ≈ 54.05

Therefore, the price of each floor seat ticket is approximately $54.05.

To confirm the solution, we can substitute the value of 'x' back into the original equation:

15 * 54.05 ≈ 810.75

This equation holds true, as the left side is approximately equal to the right side. Hence, we can conclude that the solution is correct.

I hope this helps! :)

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.

A bowling alley charges $85 for a birthday party rental and $11 per guest. A family is planning a birthday party at the bowling alley and can spend up to $260. What is the maximum number of guests they can invite?

Answers

Answer: 15 People

Step-by-step explanation:

So they plan to spend $260, from that take away $85, then you'll have $175, then take away $11 15 times you'll end up with $10 and that not enough for one more guests. So 15 is your answer.

The maximum number of guests they can invite? 15 Guests

Bowling alley rental charge is 85$

after spending on the rental charge, family left with 260 - 85 = 175$

No of guest that can be invited =  175/11 =15.9      {unitary method is used}

∴The maximum no of guests that can be invited by the family money will be 15 and 10$ money left with them unused.

I would first try to get that fraction into x/100 because 100 is the easiest to work with.

In order to get from 40 to 100, you multiply by 2.5

So we should multiply 29 by 2.5 also to make it evened out.

29 x 2.5 = 72.5

72.5/100

Now we will move the decimal two places to the left on both sides because 100. is the same as 100

72.5/100. turns into .725/1

The closest thing to .725 is .7

A small business that makes candles uses a proportional amount of essential oil and wax. For 132 ounces of wax, they use 11 ounces of essential oil.

A. 54 ounces
B. 58.9 ounces
C. 121 ounces
D. 15.9 ounces

Answers

Answer:

A

Step-by-step explanation:

By proportion, ounces of essential oil for 648 ounces of wax

= 11 * 648/132

= 7128/132

= 54 ounces.

Answer: A - 54 ounces

Step-by-step explanation:

132 divided by 11 ounces = 12

First, you need to figure out the dividend that is giving you the wax-to-oil ratio. Since that is 12, we will divide the new amount of wax by that.

648 divided by 12 = 54
