Answer:

The answer to your question is 11.4 units

Step-by-step explanation:

Data

A (-3, -1)

B ( 0, 3)

C ( 1, 2)

Perimeter = ?

Formula

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

Process

1.- Find the length between the points

dAB = $\sqrt{0 + 3)^{2} + (3 + 1)^{2}}$

dAB = $\sqrt{3^{2}+ 4^{2}}$

dAB = $\sqrt{9 + 16}$

dAB = $\sqrt{25}$

dAB = 5

dBC= $\sqrt{(1 - 0)^{2} + (2 - 3)^{2}}$

dBC = $\sqrt{1^{2} + (-1)^{2}}$

dBC = $\sqrt{1 + 1}$

dBC = $\sqrt{2}$

dAC = $\sqrt{(1 + 3)^{2} + (2 + 1)^{2}}$

dAC = $\sqrt{4^{2} + 3^{2}}$

dAC = $\sqrt{16 + 9}$

dAC = $\sqrt{25}$

dAC = 5

2.- Perimeter

P = AB + BC + AC

P = 5 + $\sqrt{2}$ + 5

P = 10 + $\sqrt{2}$

P = 10 + 1.42

P = 11.4

A paper bag contains a mixture of 3 types of candy. there are 10 packs of fuzzy peaches, 7 packs of sour keys, and 3 packs of ne

sweet-ann [11.9K]

The probability that the person will be able to keep a pack of fuzzy peaches will be 0.25.

<h3>How to calculate the probability?</h3>

a. Based on the information given, the probability that the person will be able to keep a pack of fuzzy peaches will be:

= 10/(10 + 7 + 3) × 10/(10 + 7 + 3)

= 10/20 × 10/20

= 1/4

= 0.25

The probability that the person will be able to keep a pack of fuzzy peaches will be 0.25.

b. The probability to be able to keep any of the candy will be:

= (10/20 × 10/20) + (7/20 × 7/20) + (3/20 × 3/20)

= 100/400 + 49/400 + 9/400

= 158/400

= 0.395

The probability to be able to keep any of the candy will be 0.395.

c. The probability that you will not be able to keep any of the candy will be:

= (10/20 × 10/20) + (7/20 × 13/20) + (3/20 × 17/20)

= 100/400 + 91/400 + 51/400

= 242/400

= 0.605

The probability that you will not be able to keep any of the candy will be 0.605.

The product of two integers is 72. One number is two less than five times the other. Which of the following equations could be u

melisa1 [442]

Let the 2 integers be x and y.

Their product is 72, so we write: xy=72. (I)

One of them, say y, is 2 less than 5 times the other. We can write this as the equation:
y=5x-2. (II)

To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:

xy=72,

$x(5x-2)=72,$

expanding the left hand side expression we get:

$5x^2-2x=72$ .
