What is 54 percent as a fraction in simplest form
atroni [7]
54% is 54 out of 100.
There for the numerator is 54 and the denominator is 100.

\frac{54}{100}

Now, both the top and the bottom can be divided by 2. So:

\frac{54~divided~by~2}{100~divided~by~2} = \frac{27}{50}

\frac{27}{50} can't be simplified anymore, therefore, 27/50 is 54% as a fraction.

~Hope this helped :)

What is the domain of the function represented by the following graph?
Svetllana [295]

Hello!

The domain of the function are the x-values that make the function true.

Since the graph has open circles and filled in circles, the open circles make the function false (written as <) , and the filled in circles make it true (written as ≤).

From the graph, the x value -3, and 2 are open circles. While the value -0.5 are filled in circles. Also, from the interval (-0.5, 2), there is gap, so it is part of the domain.

Therefore, the domain of the function is: {x | -3 < x ≤ -0.5} ∪ {x | 2 < x < ∞}, which is the third choice.

Jimmy was supposed to multiply a certain number by 43 but by mistake he multiplied that number by 34 as a result his answer was
vredina [299]

Answer:

345

Step-by-step explanation:

We can solve this problem by two equations. Our variables will be the following:

x is the amount to be multiplied

and y is the amount that should be obtained by multiplying by 43

Thus our <u>first equation</u> is:

43x=y

But the problem tells us that there was an error and the number x was multiplied by 34, so the result failed by 3105, thus the <u>second equation</u> is as follows:

34x=y-3105

By multiplying the quantity by 34, an amount is obtained that differs from 3105 from what it would have been obtained if multiplied by 43.

Now we are going to <u>replace the first equation in the second one </u>(y=43x):

34x=43x-3105

And clear to find x:

3105=43x-34x\\3105=9x\\\frac{3105}{9}=x\\345=x

The number that jimmy was supposed to multiply by 43 is 345.

I already did the work but I wanted to double change to make sure my answer are correct. The main ones I’m not sure about are 4,
Illusion [34]

Answer:

4. Composites have many non distinct prime factors, which are used more than once, such as 2,2,5,5 (the prime factors of every multiple of 100). What that means is that there can be two, three, four, or, in fact, infinitely many composite numbers that can have the same distinct prime factors.

Step-by-step explanation:

So, yes.
