Mathematics
1 answer:
Usimov [2.4K]4 years ago
3 0

The variable you wanted to find wasn’t mentioned, so I solved for all three:

5xy + n = 12

5xy = 12 - n

x = 12-n/5y

y = 12-n/5x

n = 12 - 5xy

Which mathematical property is demonstrated 7 + 9 + 3 = 7 + 3 + 9
Nana76 [90]
The mathematical property demonstrated by 7+9+3=7+3+9 would be the commutative property. This property states that in operations such as addition and multiplication, when you switch the order of the numbers around, the result will always be the same. In 7+9+3=7+3+9, no matter what order you put the numbers in, the answer will always be 19.

A biologist is developing two new strains of bacteria. Each sample of Type 1 bacteria produces four new viable bacteria, and eac
gayaneshka [121]

The cost can be optimized by using a Linear Programming given the  linear constraint system

  • To minimize the cost, the biologist should use <u>60 samples of Type I</u> bacteria and <u>0 samples of Type II</u> bacteria

Reason:

Let <em>X</em> represent Type 1 bacteria, and let <em>Y</em>, represent Type II bacteria, we have;

The constraints are;

4·X + 3·Y ≥ 240

20 ≤ X ≤ 60

Y ≤ 70

P = 5·X + 7·Y

Solving the inequality gives;

4·X + 3·Y ≥ 240

  • Y \geq 80 - \dfrac{4}{3} \cdot X (Equation for the inequality graphs)

The boundary of the feasible region are;

(20, 70)

(20, 53.\overline 3)

(60, 0)

(60, 70)

The cost are ;

\begin{array}{|c|c|c|}X&Y&P= 5\times X + 7 \times Y\\20&70&590\\20&53.\overline 3&473.\overline 3\\60&0&300\\60&70&790\end{array}\right]

  • Therefore, the minimum cost of $300 is obtained by using <u>60 samples of Type I</u> and <u>0 samples of Type II</u>
