Mathematics

Because if the number was rational then we can tell by looking at the numbers. The rational number should be one number or a repeating decimal or terminating number. plus because if a number was like this 5.7696... that means its irrational because we dont know the end of the number. The rational numbers are terminating numbers or either decimal or repeating numbers because we know the end of those numbers.

How do you solve 3/5×4 1/6?
Helen [10]
\frac{3}{5} × 4 \frac{1}{6}

First, convert 4\frac{1}{6} to an improper fraction. Use this rule: a \frac{b}{c} = \frac{ac+b}{c} / Your problem should look like: \frac{3}{5} × \frac{4x6+1}{6}
Second, simplify 4 × 6 to 24. / Your problem should look like: \frac{3}{5} × \frac{24+1}{6} 
Third, simplify 24 + 1 to 25. / Your problem should look like: \frac{3}{5} × \frac{25}{6}
Fourth, apply this rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd} / Your problem should look like: \frac{3x25}{5x6}
Fifth, simplify 3 × 25 to 75. / Your problem should look like: \frac{75}{5x6}
Sixth, simplify 5 × 6 to 30. / Your problem should look like: \frac{75}{30}
Seventh, simplify. / Your problem should look like: \frac{5}{2}
Eighth, convert to mixed fraction. / Your problem should look like: 2\frac{1}{2}

Answer: 2 \frac{1}{2}

Solve the proportion.<br> 3/6 = 7/d
AysviL [449]

To solve this proportion:

\frac{3}{6} =\frac{7}{d}

Simplify 3/6, it reduces to 1/2

\frac{1}{2} =\frac{7}{d}

Then do the Criss cross method

1d = 7 ×2

d=14

Hope it helps!

Find f(x) and g(x) so that the function can be described as y = f(g(x)). (5 points) y = eight divided by square root of quantity
zubka84 [21]

Answer:

  • f(x) = 8/√x
  • g(x) = 2x+4

Step-by-step explanation:

For this sort of problem, there can be an infinite number of answers.

It can be convenient to choose one of the simpler answers by looking at the operations that are performed on the variable. Here, you have ...

  • 2 multiplies it
  • 4 is added to the product
  • the square root is taken
  • 8 is divided by that root

You can work from the bottom up and define the outer function (f(x)) to be any of these operations. In our answer above, we have elected to include the "square root" and the "8 divided by that root" in our definition of f.

Then our function g takes care of the other operations.
