Answer:

<h2>Irrational numbers have a few set of numbers</h2>

Step-by-step explanation:

Irrational numbers

This means all numbers that cannot be expressed as a simple fraction they are a set of special numbers

1. Integers are number from 1,2,3 to infinity plus their negatives also, hence the list is endless

2. Rational numbers are numbers that exist from the division of two numbers example 7/5 this is a fraction in which 7 is the numerator and 5 is denominator

3. Natural numbers, all positive counting numbers the list is also endless

What is the equation of a line that is parallel to -x+3y=6 and passes through the point (3,5)?

Elena-2011 [213]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

We have the following line:

$-x + 3y = 6\\3y = x + 6\\y = \frac {1} {3} x + \frac {6} {3}\\y = \frac {1} {3} x + 2$

Thus, the slope is: $m_ {1} = \frac {1} {3}$

Then $m_ {2} = \frac {1} {3}$

So, the line is of the form:

$y = \frac {1} {3} x + b$

We substitute the point $(x, y) :( 3,5)$ and find b:

$5 = \frac {1} {3} (3) + b\\5 = b$

Thus, the equation is:

$y = \frac {1} {3} x + 5$

Answer:

$y = \frac {1} {3} x + 5$

A specific park is rectangular-shaped and has a 3 mile-perimeter. The length is 4 times the width. What are the dimensions of th

avanturin [10]

Answer:

The length of the rectangular park is $1.2\ mi$ and the width of the rectangular park is $0.3\ mi$

Step-by-step explanation:

Let

x ----> the length of the rectangular park

y ---> the width of the rectangular park

we know that

The perimeter is equal to

$P=2(x+y)$

$P=3\ mi$

$3=2(x+y)$ -----> equation A

$x=4y$ ----> equation B

substitute equation B in equation A and solve for y

$3=2(4y+y)$

$3=10y$

$y=0.3\ mi$

Find the value of x

$x=4(0.3)=1.2\ mi$

therefore

The length of the rectangular park is $1.2\ mi$ and the width of the rectangular park is $0.3\ mi$

Working together, two identical water pumps can fill a pull in 10 hours. Determine whether quantities (number of pumps and hours

vovikov84 [41]

Answer:

The number of pumps and hours) vary inversely.

The constant of variation is 20.

Step-by-step explanation:

Let x be number of pumps and y be number of hours.

We have been given that working together, two identical water pumps can fill a pull in 10 hours. This means while working alone the pumps will take 2 times as much time to fill the tank.

As we increase number of pumps (x), number of hours (y) is decreasing and as we decrease x our y is increasing, therefore, number of pumps (x) and hours (y) vary inversely.

Since we know that an inversely proportion equation is in form: $y=\frac{k}{x}$ , where, k is constant of variation.
