What is the distance between (9,1) to (1,8)
Fiesta28 [93]

Answer:

The distance between (9,1) to (1,8) is 3.26

Step-by-step explanation:

To solve this exercise we first have to calculate the distances between the factors of x and those of y

(x , y)

P1 = (9 , 1)

P2 = (1 , 8)

To calculate the distance we have to do P1 - P2

(9 , 1) - (1 , 8)

we subtract the corresponding from each other

9 - 1 = 8

1 - 8 = -7

(8 , -7)

Now that we have obtained these values, what we have to do is Pythagoras, since x represents a horizontal displacement, and y represents a vertical one, and the distance will be the hypotenuse that is formed from them.

h² = 8² + (-7)²

h² = 64 + 49

h² = 113

h = √113

h = 3.26

The distance between (9,1) to (1,8) is 3.26

John bought 8 birds and 6 pigeons for $2400. If he had bought 1 more pigeon and 2 fewer birds, he would have paid $200 more. Wha
Alex

Answer: 1 pigeon is $320

1 love bird is $80

Step-by-step explanation:

Let the cost for 1 love bird be represented by x

Let the cost for 1 pigeon be represented by y.

Since John bought 8 birds and 6 pigeons for $2400. This will be:

8x + 6y = 2400 ...... i

If he had bought 1 more pigeon and 2 fewer birds, he would have paid $200 more. This will be:

6x + 7y = 2600 ...... ii

8x + 6y = 2400 ...... i

6x + 7y = 2600 ...... ii

Multiply equation i by 6

Multiply equation ii by 8

48x + 36y = 14400 ...... iii

48x + 56y = 20800 ...... iv

Subtract iii from iv

20y = 6400

y = 6400/20

y = 320

1 pigeon is $320

From equation i

8x + 6y = 2400

8x + 6(320) = 2400

8x + 1920 = 2400

8x = 2400 - 1920

8x = 480

x = 480/8

x = 60

1 love bird is $80
