ILL GIVE YOU BRAINLIEST IF YOU GET IT RIGHT AND EXPLAIN A circular walkway surrounds a fountain.The fountain alone has a diameter of 16 feet.The walkway adds an additional 4 feet to each side. What is the area of the walkway minus the area of the fountain. Use 3.14 for Pi.

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

$A_(circle)=\pi r^2\n\nA=\pi r_(walkway)^2-\pi r_(fountain)^2\n\nA=\pi(20^2-16^2)=244\pi$

use a calculator fo find the value

Answer 2

Answer:

Answer:

a = 452.16 ft² area of walkway

a = -351.68 ft² area of the walkway minus the area of the fountain

Step-by-step explanation:

Area fountain

a = π16²

a = 256π

Area fountain and walkway

a = π(16 + 4)²

a = π20²

a = 400π

Area Walkway

a =400π - 256π

a = 144π

a = 144 * 3.14

a = 452.16 ft²

------------------------------

I think the Area of the Walkway is what the question should be asking for, but it asked for

"the area of the walkway minus the area of the fountain"

a = 144π - 256π

a = -112π

a = -112 * 3.14

a = -351.68

Solve the following system by elimination x - 4y= 2 and 4x - 16y = 8

Answers

Answer:

0=0

or as separate equations:

y=1/2

X=4y+2

Explanation:

If we solve your system by elimination:

x−4y=2;4x−16y=8 -->

Multiply the first equation by -4,and multiply the second equation by 1.

−4(x−4y=2)

1(4x−16y=8)

Becomes:

−4x+16y=−8

4x−16y=8

Add these equations to eliminate x:

0=0

Sleeping in college. A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 25 students. On average, the sampled students slept 6.25 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.

Answers

Answer:

Sample mean = 6.25 hours per night.

Population mean = 5.5 hrs of sleep each night.

Step-by-step explanation:

A sample mean is the mean of the sample collected. The 25 students surveyed by the student is the sample. The average sleep time derived from the sample is the sample mean.

A population mean is the mean of all the population. Here the population are college students. The population mean is the mean derived from studying the sleep duration of all the population - college students

Answers

Answer:

The answer is option D.

Step-by-step explanation:

First we must first find the LCM

The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is

x² + 3x + 2

So we have

$\frac{x}{ {x}^(2) + 3x + 2 } - (1)/((x + 2)(x + 1)) \n \n = \frac{x - 1}{ {x}^(2) + 3x + 2 }$
