13.

230 per hour. multiply 230 by the number of hours to find total posters.

The equation is Total = 230 x hours written as T = 230x, where x is the number of hours.

you have the total, so replace t with the value and solve for x:

1265 = 230x

Divide both sides by 230:

x = 1265 / 230

x = 5.5 hours.

Mean is the average. To find the average, add the four scores together and divide by 4.

The expression is Mean = ( score 1 + score 2 + score 3 + score 4)/4

Replace what is known:

20 = (25 + 15 + 18 + p)/4

Simpligy:

20 = (58 +p) /4

Multiply both sides by 4:

80 = 58 + p

Subtract 58 from both sides:

p = 80 - 58

p = 22

Answer:

1/16

Step-by-step explanation:

1/2 divided by 8= 0.0625

There is not much that can be done to figure out how to write 0.0625 as a fraction, except to literally use what the decimal portion of your number, the .0625, means.

Since there are 4 digits in 0625, the very last digit is the "10000th" decimal place.

So we can just say that .0625 is the same as 0625/10000.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest

terms by dividing both the numerator and denominator by 625.

Why divide by 625? 625 is the Greatest Common Divisor (GCD)

or Greatest Common Factor (GCF) of the numbers 625 and 10000.

So, this fraction reduced to lowest terms is

So your final answer is: 1/16

Would the quotient be the same if you multiply by numerator and the denominator by 100? Explain

tamaranim1 [39]

Answer:

Yes, the quotient will be the same

Step-by-step explanation:

we know that

If the numerator and denominator of a fraction be both multiplied by the same number, the quotient will not be altered

Because is the same that you multiply the fraction by 1, and remember that when you multiply by 1, you always get your original number

$\frac{a}{b}(\frac{100}{100})=\frac{a}{b}(1)=\frac{a}{b}$

therefore

Yes, the quotient will be the same

Give an example of an odd function and explain algebraically why it is odd.

tatuchka [14]

An odd function is a function of a form $y=x^n$ where n is an odd number.

Some examples would be functions:

$y=x,y=x^3,\dots$ .

A formal definition of odd function is the following.

(Algebraic proof).

Let $f:\mathbb{R}\to\mathbb{R}$ (real function).

The function is odd if the below equation is true for all x and -x for which the function is defined:

$f(x)=-f(-x)$ .

Hope this helps.
