Using proportions, it is found that 5449.62 QR is equal to HKD 315920.

<h3>Proportions</h3>

This question is solved by <em>proportions</em>, using a rule of three.

<h3>Conversion of KR to HKD:</h3>

2000 Qr are equal to 157960 NC. 1 HKD is equal to 13.62 NC, hence, how many QR are worth 13.62 NC?

Hence, the <em>rule of three</em> is:

2000 QR - 157960 NC

x QR - 13.62 NC

Applying cross multiplication:

$157960x = 200(13.62)$

$x = \frac{200(13.62)}{157960}$

$x = 0.01725$

Then:

We have that 1 HKD is equals to 0.01725 QR. How many QR are equal to HKD 315920?

Then, the second <em>rule of three</em> is:

1 HKD - 0.01725 QR

315920 HKD - x QR

Applying <em>cross multiplication:</em>

$x = 0.01725(315920) = 5449.62$

5449.62 QR is equal to HKD 315920.

prohojiy [21]

Answer:

Total possible ways to select 6 teachers from 34 teacher are $^{34}C_6=1344904$ .

Step-by-step explanation:

It is given that total number of teachers at a school is 34.

The school director must randomly select 6 teachers to part in a training session.

$^nC_r=\frac{n!}{r!(n-r)!}$

Where, n is total possible outcomes and r is number of selected outcomes.

Total teachers = 34

Selected teachers =6

Total number of possible ways to select 6 teachers from 34 teacher is

$^{34}C_6=\frac{34!}{6!(34-6)!}$

$^{34}C_6=\frac{34\times 33\times 32\times 31\times 29\times 28!}{6!(28)!}$

$^{34}C_6=1344904$

Therefore total possible ways to select 6 teachers from 34 teacher are $^{34}C_6=1344904$ .

If the area around the vegetable garden is of uniform width (labeled with x) and the dimensions of the vegetable garden is 45 fe

Nady [450]

Area of Rectangle = Width × Length

Vegetable Garden
Width = 20
Length = 45
Area of Vegetable Garden = 20×45=900 Sq ft

Area of Entire Garden = Width × Length
Width = 20 + 2x
Length = 45 + 2x
Area = (20 + 2x)(45 + 2x)
(2x + 20)(2x + 45)
4x^2 + 90x + 45x + 900
Area of Entire Garden = 4x^2 + 135x + 900

Area of Flower Garden = Area of Entire Garden - Area of Vegetable Garden

(4x^2 + 135x + 900) - (20 × 45)
4x^2 + 135x + 900 - 900
Area of Flower Garden = 4x^2 + 135x
