Answer:

The required irrational number between 12.1 and 12.2 is 12.1243536859.....

Step-by-step explanation:

To find : What is a irrational number between 12.1 and 12.2 ?

Solution :

An irrational number is defined as the number written in $\frac{p}{q}$ form or in proper fraction where p and q are integers and q is non-zero.

An irrational numbers are non-terminating and non-repeating.

So, An irrational number between 12.1 and 12.2 is any number which is non-terminating and non-repeating there are so many in between.

Let's take, 12.1243536859......

Therefore, The required irrational number between 12.1 and 12.2 is 12.1243536859......

kotykmax [81]

The equation would have to be set up as 4b - 4 = 10.36. This is because you’re buying 4 boxes of fruit loops, and $1 taken off each box is $4 total for all four boxes.

Rectangle with area of 10 and length of 2 1/2. Whats the width?

Stels [109]

Hello!

We have been given enough information to solve this question!
We know that the length of the rectangle is 2.5, and we also know how to find the area:

A = l × w

But we don't need the area, we need to find the width of the rectangle! You see, we had to multiply the length by the width to find the area.

Now, to find the width, we must flip the problem around and use the opposite of multiplication, which is division.

W = a ÷ l

W = 10 ÷ 2.5

W = 4

Therefore, the width of the rectangle is 4.

Airida [17]

<h2><u>N-FACTORIAL!</u></h2>

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{1}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\: \bold{ \red{6!}= 6×5×4×3×2×1= \boxed{ \bold{ \blue{720}}}}$

Therefore, <u>the value of 6! is 720</u>.

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{2}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\bold{3! \cdot 2! }\implies \bold{(3×2×1) \cdot( 2×1 )}$

$\: \: \: \: \: \: \: \: \: \: \: \: \implies \: \bold{ 6 \times 2} = \boxed{ \bold{ \blue{12}}}$

Therefore, <u>the value of the given expression is 12.</u>

<h3><u>EXPLANATION</u><u>:</u></h3>

The mathematical symbol n! is read as "n factorial". The exclamation point "!" is read as factorial. And please remember or take note that 0! is equal to 1, and 1! is also equal to 1.

If the 10th of the 10 consecutive numbers is 10, what is their sum?

liq [111]

Represent these consecutive numbers (assuming that they are all integers):

x
x+1
x+2
x+3
x+4
x+5
and so on
x+8
x+9 is the tenth number. x+9 = 10, so x = 9.

Think of it this way: there are 10 consecutive numbers, and the last one is 10.

Working backwards, we get the sequence 10, 9, ... 3, 2, 1.

The sum of such an arith sequence is equal to the count of the numbers times the average of the first and last terms:

sum here = 10(1+10)/2 = 5(11) = 55 (answer)
