Answer: (D) \frac{y-x}{y+x}

Explanation:

\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}=\frac{y-x}{y+x}

Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.

trapecia [35]

Answer:

-212800

Step-by-step explanation:

7.2 × 10³ = 7.2 × 1000 = 7200

2.2 × 10 to the power 5 = 2.2 × 100000 = 220000

7200 - 220000 = -212800

Analyze the diagram below and complete the instructions that follow.
Phantasy [73]

Answer:

Option (B)

Step-by-step explanation:

From the figure attached,

ΔBCD and ΔACE are the similar triangles.

Therefore, by the property of similar triangles, corresponding sides of these similar triangles will be proportional.

\frac{AC}{BC}= \frac{EC}{DC}

\frac{AB+BC}{BC}= \frac{ED+DC}{DC}

\frac{AB+6}{6}= \frac{24+8}{8}

\frac{AB+6}{6}= \frac{32}{8}

\frac{AB+6}{6}=4

AB + 6 = 24

AB = 18

Option (B) will be the answer.

Azul spun a tri-color spinner twice. What is the probability that the spinner landed on the colors blue and green in any order?
guapka [62]

Answer:

The Probability that the spinner landed on the colors blue and green in any order = 2/9

Step-by-step explanation:

Given - Azul spun a tri-color spinner twice.

To find - What is the probability that the spinner landed on the colors blue and green in any order?

Solution -

Given that,

A tri-color spinner spun twice

So,

The Sample Space, S = {BB, BG, BY, GB, GG, GY, YB, YG, YY}

⇒n(S) = 9

Now,

Let A be an event that the spinner landed on the colors blue and green

So,

A = {BG, GB}

⇒n(A) = 2

Now,

Probability that the spinner landed on the colors blue and green in any order = n(A) ÷ n(S)

         = 2 ÷ 9

∴ we get

The Probability that the spinner landed on the colors blue and green in any order = 2/9

What is the distance around a triangle that has sides measuring 2/18 feet 3/12 feet and 2/12 feet
Minchanka [31]
The distance around an object is called the perimeter. To get the perimeter, you add up the sides. So, 2/18 + 3/12 + 2/12 = your answer.
