<u>Answer:</u>

The value of $\frac{\left(\frac{y}{5}\right)+1}{\left(\frac{y^{2}}{25}\right)-1}=\frac{5}{y-5}$

<u>Solution:</u>

As given, $\frac{\left(\frac{y}{5}\right)+1}{\left(\frac{y^{2}}{25}\right)-1}$

$\frac{\left(\frac{y}{5}\right)+1}{\left(\frac{y}{5}\right)^{2}-1^{2}}$

$\frac{\frac{y}{5}+1}{\left(\frac{y}{5}+1\right) \times\left(\frac{y}{5}-1\right)}$

as we know $\left(a^{2}-b^{2}\right)=(a+b)\times(a-b)$

This can be written as,

$\Rightarrow \frac{\frac{y}{5}+1}{\frac{y}{5}+1} \times \frac{1}{\frac{y}{5}-1}$

Because $\Rightarrow \frac{\frac{y}{5}+1}{\frac{y}{5}+1}=1$

$\Rightarrow 1 \times \frac{1}{\frac{y}{5}-1} = \frac{5}{y-5}$

How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees

Step2247 [10]

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

$A=\dfrac{\theta}{360^\circ}\pi r^2$

Where, $\theta$ is the central angle in degrees.

Putting r=10 and $\theta=45^\circ$ , we get

$A=\dfrac{45^\circ}{360^\circ}\pi (10)^2$

$A=\dfrac{1}{8}\pi (100)$

$A=12.5\pi$

Therefore, the area of the sector is 12.5π sq. inches.

vesna_86 [32]

Question: The sample data and the scatter plot was not added to your question. See the attached file for the scatter plot.

Answer: Yes

Step-by-step explanation:

From scatter plot, it was discovered that there is a linear relationship between the two variables and both variables are quantitative.

Therefore, it appropriate to use the correlation coefficient to describe the strength of the relationship between "Time" and "Fish Quality"?

Hakim saves money for one year to buy a computer.

elena55 [62]

Answer:

$111

Step-by-step explanation:

First we need to take a look at the bank account of Hakim. Hakim initially invested $700 in the bank with a 5% simple interest annually. Since Hakim waited for an entire year before buying the computer, he will then have the extra 5% interest from the bank.

Let's first compute for how much Hakim will have in total in the bank.

A = P(1 + rt)

P = 700 Initial Investment

r = 5% or 0.05 Interest

t = 1 Year

A = 700(1 + (0.05 x 1))

A = 700(1 + 0.05)

A = 700(1.05)

A = 735

So now we know that Hakim has a total of $735 in his bank account.

Now let's move on to calculating the total cost of the computer. We know that the sales tax is always computed after the discounted price.

So first we find the discounted price.

x = 750

d = 20% or 0.20

Discount = 750 x 0.20

Discount = 150

Now that we have the discount of the computer, we then simply subtract the discount to the initial price.

750 - 150 = 600.

The computer will then cost $600 with the discounted price.

Now we have to find the sales tax.

Sales Tax = 4% or 0.04

Total Discounted Price = 600

600 x 0.04 = $24

Now that we have the sales tax, we simply add the sales tax to the discounted price.

600 + 24 = 624.

Now that we know how much the total cost of the computer is with the discount and sales tax, we simply subtract the total cost of the computer to Hakim's current account balance.

735 - 624 = 111

Hakim will have a total of $111 in his bank account after purchasing the computer.
