To get the equivalent you have to half the denominator and the numerator so therefore it is 1/5 as you divide it by 2.

Which expression is equivalent to the following complex fraction? 1+1/y /1-1/y

Mrac [35]

Answer:

$\frac{y+1}{y-1}$

Step-by-step explanation:

To solve a complex fraction like $\frac{(1+\frac{1}{y} )}{(1-\frac{1}{y} )}$ , take LCM of both the terms separately first to get:

$1+\frac{1}{y}$ = $\frac{y+1}{y}$

and

$1-\frac{1}{y} = \frac{y-1}{y}$

Now combine and divide these terms to get:

$\frac{\frac{y+1}{y} }{\frac{y-1}{y} }$

The term $y$ in both the denominators will be cancelled out by each other and you will be left with:

$\frac{y+1}{y-1}$

Therefore, the expression $\frac{y+1}{y-1}$ is equivalent to the given complex fraction.

A rectangular piece is cut from a circular sheet as shown on the diagram below. The length and width of the rectangle is 12 cm b

mojhsa [17]

Answer:

The area of remaining sheet is 1077cm²

Step-by-step explanation:

First, you have to find the area of circle using the formula, A = πr², where r is the radius of circle:

r = 20cm

A = π × 20²

= 400π cm²

Second, you have to find the area of rectangle:

A = 12 × 15

= 180 cm²

Lastly, you need to substact the area of rectangle feom the area of circle to find the remaining sheet that has not being cut:

A = 400π - 180

= 1077 cm² (3s.f)

Question 9 of 26

Arturiano [62]

Answer: f(x) = 1.2(x/2) if 120 ≤ x ≤ 240

Step-by-step explanation:

Let, she made f(x) sundaes in x minutes.

Then according to the question,

She just makes sundaes for a single shift of at most 4 hours and at least 2 hours,

⇒ She can make sundaes for a single shift of at most 240 minutes and at least 120 minutes,

That is, 120 ≤ x ≤ 240

Now, She can prepare 1 sundae every 2 minutes,

⇒ She can prepare 1/2 sundae every 1 minutes,

⇒ She can prepare x/2 sundae every x minutes,

Also, she earns $1.20 for each sundae she makes.

Thus, her total earning in x minutes,

$f(x)= 1.2\times \frac{x}{2}$

⇒ $f(x)= 1.2(\frac{x}{2})$

Where, 120 ≤ x ≤ 240

Which is the required function related her earnings to the number of minutes she works.
