The price,

attashe74 [19]

Answer:

Step-by-step explanation:

You have to look at the second term to be sure of the meaning of t - 15n

What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.

The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.

C is out of the question. The information talks about 2 dollars per increase which is the first term.

A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)

The answer is B

The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near

svet-max [94.6K]

Explanation:

Formula to calculate pH of a chemical or solution is as follows.

pH = $-log [H^{+}]$

Therefore, calculate the pH of given chemicals as follows.

1). Oven cleaner

pH = $-log [H^{+}]$

= $-log [10^{-13}]$

= 13

2). Water

pH = $-log [H^{+}]$

= $-log [7 \times 10^{-7}]$

= 6.15

3). Blood

pH = $-log [H^{+}]$

= $-log [4 \times 10^{-8}]$

= 7.40

4). Vinegar

pH = $-log [H^{+}]$

= $-log [63 \times 10^{-4}]$

= 2.20

What is the gcf of h4 and h8

Tamiku [17]

Answer: $GCF=h^4$

Step-by-step explanation:

You need to remember that:

1) The definition of Greatest common factor (GCF): This is the greatest factor that divides two numbers.

2) The Product of powers property states that:

$(a^m)(a^n)=a^{(m+n)}$

3) To find the Greatest common factor between two numbers, for example, you can descompose them into their prime factors and then choose the commons with the lowest exponent.

In this case, you have $h^4$ and $h^8$

You can observe that the common base is "h", then you only need to choose the one with the lowest exponent. This is:

$GCF=h^4$

4) You can also rewrite $h^4$ and $h^8$ as:

$h^4=h*h*h*h\\*h^8=h*h*h*h*h*h*h*h$

You can observe that the common factor between $h^4$ and $h^8$ is: $h*h*h*h=h^4$

Then:

$GCF=h*h*h*h=h^4$

Evaluate the expression below when y = -3. 2y + 7 -4y − 10 A

GREYUIT [131]

Hello!

Judging by the question you have provided I have figured that the best way to go about finding the solution is by using the distributive property!

This means you will want to distribute the y = -3 into the 2y+7-4y-10 equation.

However, the first step you should take is to simplify the equations.
After simplifying the equations you should come out with the new equation being -2y-3.

You now want to distribute the y=-3 into the equation!
You should get -2(-3)-3. Now solve!

The answer you get should be 3!

Hope this helped!
