geniusboy [140]

Answer:

1. f

2. a

3. b

4. e

5. c

6. d

1. I figured out how to order them by using the distance formula to calculate how far each point was, from the other.

2. (1, -10) and (1, -11)

3. (1, -10) and (1, 11)

Step-by-step explanation:

<u>Using Letter A, as example:</u>

To calculate the distance between the points, you use the formula:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d = \sqrt{(2-2)^2+(10-4)^2}

d = \sqrt{0 + 36}

d = 6

Just do the same thing (plug in the numbers into the formula), and you should be able to get the correct answers.

6 labour complete a work in 12 days. How many labours should added to complete the works in 8 days?​
mario62 [17]

Answer:

9 labours

Step-by-step explanation:

In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.

In indirect proportion, if one quantity increases, the other decreases and vice versa.

As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.

6 labours => 12 days

x labours =>  8 days

Since its an inverse proprotion, multiply 6 with 12, and x with 8.

8x = 6 × 12

x = \frac{6*12}{8}

∴ x = <u>9 labours</u>

oee [108]
We can write the equation 9x=4500

Now we just solve for x by dividing both sides by 9 to get:
x=500 

Hope this helps!
