The first step for solving this expression is to subtract the numbers in the first set of parenthesis.
(2 ÷ 12) × 2
Now write the division as a fraction.
$\frac{2}{12}$ × 2
Reduce the fraction with 2.
$\frac{1}{6}$ × 2
Finally,, reduce the fraction with 2 one last time.
$\frac{1}{3}$
This means that the correct answer to your question is $\frac{1}{3}$ .
Let me know if you have any further questions.

The graph of y=√x is shifted 3 units down and 2 units right. Which equation represents the new graph?

kolbaska11 [484]

The general form would be: $y = a \sqrt{x-b} + c$ where 'a' is responsible for the magnitude of the function, 'b' is responsible for horizontal shift.and 'c' is responsible for vertical shift of the function.

Your answer would be: $y = \sqrt{x-2} -3$

Looks like choice A

What is the radical expression that is equivalent to the expression 27 1/5? Enter your answer as a radical. For example, if your

yuradex [85]

Answer:

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$

Step-by-step explanation:

we are given

$27^{\frac{1}{5} }$

we can use rule to change exponent into radical

$\sqrt[n]{a} =a^{\frac{1}{n} }$

so, we can write as

$27^{\frac{1}{5}}=(3\times 3\times 3)^{\frac{1}{5}}$

$27^{\frac{1}{5}}=(3^3)^{\frac{1}{5}}$

now, we can use rule

and we can write our term as

$27^{\frac{1}{5} }=\sqrt[5]{3^3}$

The side lengths of a triangle are 5, 8, and 12. Is this a right triangle?

professor190 [17]

Answer:

A) No...

Step-by-step explanation:

We can check if this triangle is a right triangle by using the Pythagorean Theorem.

a² + b² = c²
where a and b are the legs of the right triangle, and c is the hypotenuse (longest side)

Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:

5² + 8² = 12²

Simplify.

25 + 64 = 144

89 = 144

We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.

Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.

This leaves us with answer choice A. 52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)
