Answer:

fraction

Step-by-step explanation:

If you have a negative exponent, such as x^{-2}, that can also be written as \frac{x^{-2} }{1}

by moving the exponent (and it's base) to the denominator (the other side of the fraction, since it's in the numerator), you make the exponent positive: \frac{1}{x^{2} }

What is the mean of the data set? {96, 84, 92, 96, 100} Enter your answer in the box. Round to the nearest tenth.
vodomira [7]
In order to calculate the mean (average) you add up all the numbers and divide the total by how many numbers there are.

The sum of the data set is 468.

There are 5 numbers in the set.

468 divided by 5 is 93.6.

The answer is already to the nearest tenth, so the mean is 93.6.

A student cost for last semester at her community college was $3000. She spent $540 of that on books. What percent of last semes
eduard
Hi there!
We can set up a ratio to model the problem...
540/3000 = x/100
Now, just cross multiply and solve for x.
54000 = 3000x
x = 18
Therefore, 18 percent of last semester's college costs was spent on books. Hope this helped and have a great day!

She gave 1/3 of cookies for her husband 1/4 of the cookies to her son and 1/6 of a cookies to her neighbor she ate the remaining
beks73 [17]

She made 15 cookies

<em><u>Solution:</u></em>

Let "x" be the number of cookies she made

She gave 1/3 of cookies for her husband

Therefore,

Husband = \frac{1}{3}x

Find the remaining

Remaining = x - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}

1/4 of the cookies to her son

Therefore,

son = \frac{1}{4} \times \frac{2x}{3} = \frac{x}{6}

Now again find the remaining

Remaining = \frac{2x}{3} - \frac{x}{6} = \frac{x}{2}

1/6 of a cookies to her neighbor

Neighbor = \frac{1}{6} \times \frac{x}{2} = \frac{x}{12}

Now again find the remaining

Remaining = \frac{x}{2} - \frac{x}{12} = \frac{5x}{12}

She ate the remaining six cookies

Therefore,

\frac{5x}{12} = 6\\\\5x = 72\\\\x = 14.4

Thus she made approximately 15 cookies

For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric
Anon25 [30]

Answer:

a=16400 feet

Step-by-step explanation:

t = -0.0035 a +g

-17.40 = -0.0035 a+40

-17.40-40=-0.0035a+40-40

-57.40=-0.0035a

a = -57.40/-0.0035

a=16400 feet
