Vinil7 [7]

Answer:

A total of 53 sales to qualify for bonus

Step-by-step explanation:

In the first week, they required a sale of 20 tickets to recieve a bonus.

In subsequent weeks, they require a sale of (n + 3)

Where n = number of sale the previous week

Week 2, they'll require n + 3 = (20 + 3) sales = 23 sales

Week 3 = 23 + 3 = 26 sales

Week 4 = 26 + 3 = 29 sales

Week 5 = 29 + 3 = 32 sales

Week 6 = 32 + 3 = 35 sales

Week 7 = 35 + 3 = 38 sales

Week 8 = 38 + 3 = 41 sales

Week 9 = 41 + 3 = 44 sales

Week 10 = 44 + 3 = 47 sales

Week 11 = 47 + 3 = 50 sales

Week 12 = 50 + 3 = 53 sales

At the end of week 12, they require a total of 53 sale to qualify for bonus

Hii! I need some help, would anyone mind helping me?

Kisachek [45]

Step-by-step explanation:

${x}^{2} - 14x - 25 {y}^{2} + 100y = 76$

Factor by grouping,

$( {x}^{2} - 14x) - (25 {y}^{2} - 100y) = 76$

Complete the square, with the x variables,

$( {x}^{2} - 14x + 49) - (25 {y}^{2} - 100y) = 125$

Factor out 25 for the y variables

$( {x}^{2} - 14x + 49) - 25( {y}^{2} - 4y) = 125$

Complete the square

$( {x}^{2} - 14x + 49) - 25( {y}^{2} - 4y + 4) = 25$

Simplify the perfect square trinomial

$(x - 7) {}^{2} - 25(y - 2) {}^{2} = 25$

Make the right side be 1 so divide everything by 25.

$\frac{(x - 7) {}^{2} }{25} - (y - 2) {}^{2} = 1$

Here our center is (7,2).

on a scale drawing, 5 metres is represented by 4 centimetres. write the scale as a ratio in it's simplest form.

ryzh [129]

Answer:

<em>The scale factor is 1:125</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling which consists of multiplying or dividing by a constant factor. We use scaling when representing geographic locations on a map.

On a scale drawing, a distance of 5 meters = 500 cm is represented by 4 centimeters. The scale factor is usually represented as a ratio of the smallest to the biggest magnitude:

$\frac{4}{500}=\frac{1}{125}$

The scale factor is 1:125
