INSERT TWO RATIONAL NUMBERS BETWEEN 2 AND 3. How to find them?

1 answer:

3 0

There are an infinite number of them.
Here are a few:

2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.

How to find them:

You probably never heard this before, but I'll bet
you'll remember it from now on:

ANY number that you can write down on paper completely, using digits
and a decimal point if you need it but no symbols, is a rational number.

If you can write it down completely without any 'comments', then it's rational.

Add the two expressions. 8.9x−5 and −6.8x+8 Enter your answer, in simplified form, in the box.

Verizon [17]

Let's simplify step-by-step.8.9x−5−6.8x+8=8.9x+−5+−6.8x+8

Combine Like Terms:=8.9x+−5+−6.8x+8=(8.9x+−6.8x)+(−5+8)=2.1x+3

The simplified answer is 2.1x+3

How do you find x? and how do you round to the nearest tenth?

expeople1 [14]

Hey there!

In order to solve this problem, we can use the Pythagorean Theorem, which is $c^2 = a^2 + b^2$ . Since the Pythagorean Theorem would find only half of the length of x, we'll need to double it in the end.

First, let's plug in what we know to the Pythagorean Theorem: $2.1^2 = 1.4^2 + b^2$

Next, we'll simplify to that $b^2$ is by itself:

$b^2 = 2.45$

Then, we'll find the square root of 2.45, multiply that by 2 and round to the nearest tenth:

$2(\sqrt{2.45} ) = 3.1$

Therefore, x = 3.1 ft.

How to round to the nearest tenth:

In a decimal, the tenth is the first number after the decimal point. To round to the tenth, if the number in the hundredth place is less than 5, you keep the number as it is, but if the number in the hundredth place is more than 5, you increase the number in the tenth place by 1.

Hope this helps!! :)

Using isosceles triangle theorems solve for x and y

klio [65]

Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5

Hope this helps! If you have anymore questions just ask!

Y_Kistochka [10]

Answer:

x=3i-2,x=-3i-2

Step-by-step explanation:

x+2= $\sqrt{-9} : x=- 3i-2$

= x=3i-2,x=-3i-2

Hoped this helps you!! :D
