Which is the simplified form of n Superscript negative 6 p cubed?

evablogger [386]

Answer:

Third option. $\frac{p^3}{n^{6}}$

Step-by-step explanation:

For this exercise you need to remember one of the properties for exponents.

There is a property called the "Negative property of exponents" which states the following:

$b^{-n}=\frac{1}{b^n}$

Where $b \neq0$

As you can observe, $b^n$ is the reciprocal of $b^{-n}$

In this case you have the following expression given in the exercise:

$n^{-6}p^3$

Observe the expression. As you can notice, the base "n" has a negative exponent, which is -6.

Therefore, applying the Negative property of exponents explained at the beginning of this explanation, you can simplify the expression.

Then, the simplified form of $n^{-6p^3}$ is the one shown below:

$n^{-6}p^3=\frac{p^3}{n^{6}}$

The speed limit is 55 minutes per hr. write an inequalit to represent the speed limit.

anygoal [31]

Answer: Either $x \le 55$ or $0 \le x \le 55$ depending on your teacher's preference. See the note at the bottom for more info.

=====================================

Let x be the speed limit. It is simply a placeholder. Think of it as a box with the number inside. We don't know what the number is, but we know that the largest it can be is 55. It cannot be larger than 55.

So x can be equal to 55 or it can be smaller

Put another way, x is less than or equal to 55 which is written as $x \le 55$ (on the keyboard you would type " x <= 55 " without quotes).

---------------------------------------

Note: since negative speeds make no sense, we also must imply that x can't be negative. Your teacher may want you to write this in to clearly state it. If so, then you would also have $x \ge 0$ which when combined with the first inequality, you get this compound inequality $0 \le x \le 55$ (basically saying "x is some speed between 0 and 55 mph"). This very clearly states the boundaries on what x can be. Though your teacher may want you to stick to the first format as its simpler.

it is 10 3\5 miles from Alston to Barton and 12 1/2 from Barton to Chester.the distance from Alston to Durban,via BARTON and Che

natali 33 [55]

10 3/5 + 12 1/2 =
10 6/10 + 12 5/10 =
23 1/10 =
35 - 23 1/10 =
11 9/10 =
11 9/10 miles
Hope that helps

Express M in terms of B and n: B = 3Mn 2

Molodets [167]

We are given the expression B=3Mn/2 and told to express M in terms of B and n. This means that we should apply mathematical operations on both sides of the equation so we "isolate " M on one side of the equality sign. We begin with the given equation

$B=\frac{3\cdot M\cdot n}{2}$

First, we multiply both sides by 2, so we get

$2\cdot B=3\cdot M\cdot n$

Next, we divide by 3 on both sides, so we get

$\frac{2\cdot B}{3}=M\cdot n$

Finally, we divide both sides by n, so we get

$\frac{2\cdot B}{3\cdot n}=M$

In this case, we have succesfully expressed M in terms of B and n
