Answers

Answer:

n = 641

Step-by-step explanation:

Pipe required to provide water is 3846 m

Length of each pipe is 6 m

We need to find the no of tubes required. Let there are n tubes. It can be calculated as follows :

[tex]n=\dfrac{3846 }{6}\\\\n=641[/tex]

Hence, 641 tubes will be needed.

The average a of two numbers c and d is equal to half the sum of c and d

Answers

Answer:

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

Step-by-step explanation:

Required

Write the given statement as an equation

To start with, we solve for the average of c and d

[tex]Average = \frac{\sum x}{n}[/tex]

[tex]Average = \frac{c + d}{2}[/tex]

Next, is to determine half sum

[tex]Half\ sum = \frac{c + d}{2}[/tex]

Since both are equal; we have"

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

The above shows that the statement is true

The life zones on Mount Rainier, a mountain in Washington, can be approximately classified by elevation, as follows.

Low-elevation forest: above 1700 feet to 2500 feet
Mid-elevation forest: above 2500 feet to 4000 feet
Subalpine: above 4000 feet to 6500 feet
Alpine: above 6500 feet to the summit


Write a compound inequality that represents the elevation range h
for each type of plant life.

Answers

Answer:

Look down below

Step-by-step explanation:

It's been a little while since I've looked at compound inequalities, so forgive me if this is a bit long.

Let's start with the Low Elevation Forest. Let x represent what is considered the forest. If this is above 1700, x>1700 (which can be rewritten as 1700<x). (Remember, as silly as this may sound, the mouth of the alligator eats the larger part! So the large number has the wide part of the symbol. Remember also that if the sign is < or >, then it includes the number the 'mouth' is facing.) If the forest is up to 2500, you'll generally include 2500 in your equation, so x<2500. This means 1700<x<2500 or x>1700 and x<2500.

Now let's repeat that with the other parts of the question. Mid elevation is x>2500 and x<4000. Subalpine would be x>4000 and x<6500. Alpine is then x>6500 and x< the summit (which is probably the elevation of Mount Rainer in this problem or 14410 feet).

Now we have the question itself. Let's replace x with t for trees for part a. This would mean in the low elevation forest, t>1700 and t<2500 which can be rewritten 1700<t<2500. Now we have flowers in the subalpine AND alpine zones. Let's use f for flowers. If flowers can be in either zone, let's combine them! Because t>4000 and t<6500 in the subalpine level and t>6500 and < the summit (aka 14410 feet), flowers can grow anywhere  above 4000 feet. So flowers would be f>4000 and f<14410. Again, you can combine these into: 400<f<14410.

Sorry this is so long, but I hope it helps :)

PLEASSSS PLEAS HELPPPPP Use the function f ( x ) = 2 − 5 x to fill out the table.

Given function:

       f(x) = 2 - 5x

Table;

        x                        f(x)

         -1                          7

          1                          -3

          2                        -8

The function is f(x) = 2 -5x

For;   x = -2;        f(x) = 2 - 5(-2)  = 12

                            f(x) = 2 - 5(-1) = 7

                            f(x) = 2 - 5(0) = 2

                            f(x) = 2 - 5(1) = -3

                            f(x) = 2 - 5(2) = -8

Answer:f(x) = 2 - 5(-2)  = 12

                           f(x) = 2 - 5(-1) = 7

                           f(x) = 2 - 5(0) = 2

                           f(x) = 2 - 5(1) = -3

                           f(x) = 2 - 5(2) = -8

The function f ( x ) = 2 − 5 x.

Plug in-  f ( 2 ) = 2 − 5x2

An online music store is offering a promotion. When you spend $30 or more, you receive 3 songs for free. You buy an album for $10. Identify an inequality that represents how much more money $m$ you must spend to receive the three free songs.

Answers

Answer:

10 + m  ≥ 30

You must spend AT MOST $20 or more

Step-by-step explanation:

Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be  ≥ or the inequality will not be true.

10 + m  ≥ 30

10 - 10 + m  ≥ 30 - 10     ( subtract 10 from each side to isolate m)

m  ≥ 20     ( we are left with this )

The answer is :

m  ≥ 20

You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D

What is a cube?

A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.

Given that, a solid shape is made from 4 cubes.

The front face of a cube is square, therefore, the front elevation of 4 cubes will be either a square or a rectangle.

90 minus 50 divided by 5 times 6 plus 2

Answers

Anwer:32

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

To find out what to do first, use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, ans Subtraction)

Now it should look like this: (90-((50/5)*6)) + 2

First, divide 50 by 5 and get 10

So now it will be like this: (90-(10 x 6) + 2

Next, multiply 10 by 6 and you'll get 60.

The problem is looks like this: (90 - 60) + 2

Then, subtract 60 from 90 and get 30.

30 + 2

Lastly, add 30 and 2 to get 30.
