Answer:

true

 A numerator of a fraction is the number that is written in the upper part of it and the denominator is the number that is written in the lower part.

The answer is: True.

 The numerator of a fraction is the number that is written in the upper part of it and the denominator is the number that is written in the lower part.

 To substract f<span>ractions, they must have a common denominator. There is two cases:

 1. When the fractions have the same denominator, you just have to rewrite the denominator and substract the numerators. For example:

 8/3-1/3=(8-1)/3=7/3

 2. When the fractions have different denominators, you must calculate the Least commom multiple (LCM):

 5/2-3/4

 L.C.M.=2</span>²=4

 (10-3)/4=7/4

What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
USPshnik [31]

The simplified value of the exponential expression is 2.

<h3>How to get the simplified expression?</h3>

Here we need to simplify the expression:

16^{1/4}

First, you need to remember that:

\sqrt[n]{x} = x^{1/n}

Then we can just write:

16^{1/4} = \sqrt[4]{16}

And now, you can remember that:

2*2 = 4

Then:

2*2*2*2 = 4*4 = 16

From this, we can conclude that:

2^4 = 16\\\\\sqrt[4]{16} = 2

So we conclude that the simplified value is 2.

Is algebra.
Ket [755]

Answer:

6(x-10)(x+9)

Step-by-step explanation:

First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression 6(x^{2} +x-90). Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, 6(x-10)(x+9).

According to Greek mathematician Zeno, if each bounce of a ball is half the height of the bounce before it,the ball will never s
vovikov84 [41]
From the diagram associated with this question it can be seen that the first bounce was 1 units high, thus the second bounce is 1 / 2 = 0.5 units high and the third bounce is 0.5 / 2 = 0.25 = 1/4 units high.

Given that B represents the second bounce and C represents the first bounce, the <span>fractions in hundredths that should be written at points B is 0.50 while at point C is 0.25</span>
