Answer:

x = 8

Step-by-step explanation:

Given 2 intersecting chords in a circle.

Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x = 10 × 4 = 40 ( divide both sides by 5 )

x = 8

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>

If point p is 9/11 of the distance from M to N, what ratio does point P partition the directed line segment from M to N into?
stepan [7]

The ratio the point P partition the directed line segment from M to N is 9:2

<u>Step-by-step explanation:</u>

Let the total distance between M and N be 'd'

Point P distance from M = (9/11) d

Point P distance from N = (1 - 9/11) d

= (2/11) d

The ratio of the distance = (9/11) d / (2/11) d

= 9/2

= 9:2

The ratio the point P partition the directed line segment from M to N is 9:2

Greatest common factor between 84 and 56
s344n2d4d5 [400]
The greatest common factor is 28.

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

Then the greatest common factor is 28.
