<h3>What is the linear system?</h3>A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Suppose another company offers a special banquet price of $4,000 for 150 people.
Then the special is cheaper than Bella's price.
Then the correct option is B.

Answer:
11.51
Step-by-step explanation:
In general, a calculator is required to evaluate the irrational sum ...
π + √70
<h3>Calculator result</h3>The result from a readily-available online calculator is shown in the attachment.
π + √70 ≈ 11.51

<em>Additional comment</em>
You have probably memorized pi to several digits: 3.1416. To obtain the required estimate means you need to approximate √70 to about the same level of precision.
For a number n = a² +b, the square root can be approximated by the continued fraction ...
√n ≈ a +b/(2a +b/(2a +...))
Effectively, the root (r) can be iterated from the recursive formula ...
r' = a +b/(a +r)
For √70, we have 70 = 8² +6 ⇒ a=8, b=6
If the initial approximation of the root is r0≈a=8, then a couple of iterations gives ...
r1 = 8 + 6/(8 +r0) = 8 + 6/(8 +8) = 8 3/8
r2 = 8 + 6/(8 +r1) = 8 +6/(8 +8 3/8) = 8 48/131
This has sufficient accuracy for the purpose. The decimal equivalent of the sum then becomes ...
3.1416 +8.3664 = 11.5080 ≈ 11.51
Answer:
1. =
2. <
3. <
Step-by-step explanation:
Note: When comparing decimals you always place both decimals right above each other.
1 is equal to because once you put a 0 behind the 2.1 they are both the same.
2.10
2.1 <add 0 as space holder
2 is less than because they are both negative you are looking for which one is closest to zero.
-4.5 <add 0 as place holder
-4.25 <closest to zero
3 is less than because (pie) equals 3.141592654 which is less than 3.2.
3.141 <do not need to add whole decimal
3.2 <add two 0's as a placeholder
