1.  order pairs : (3,1), (-2,-1)

1 + 1 / 3 + 2 = 2 / 5 is the slope

2.  order pairs : (2,-3), (-3,2)

-3 - 2 / 2 + 3 = - 5 / 2 is the slope

3.  order pairs : (1,3), (-1,-2)

3 + 2 / 1 + 1 = 5 / 2 is the slope

I used the slope formula to get my answers.

There are 454 grams in a pound. There are 16 ounces in a pound. How many grams are in an ounce?
Lostsunrise [7]

Answer: There are 28.375 grams in an ounce.


Step-by-step explanation:

Given: Total grams in a pound =454 grams

Total ounces in a pound = 16 ounces

Therefore, 16 ounces = 454 grams

To find grams in an ounce, we need to divide 454 grams by 16, we get

The total grams in an ounce=\frac{454}{16}=28.375\ grams

∴The total grams in an ounce= 28.375 grams

Hence, there are 28.375 grams in an ounce.

Identify the area of the kite. HELP ASAP PLEASE!!
ExtremeBDS [4]

Answer:

2340 m^2

Step-by-step explanation:

The area of kite = multiply the lengths of the two diagonals and divide by 2

The top left triangle:

Using Pythagorean theorem:

c^2 = a^2 + b^2

so

b^2 = c^2 - a^2

b^2 = 51^2 - 24^2

b^2 = 2601 - 576

b^2 = 2025

b = 45

Top right triangle:

Using Pythagorean theorem:

c^2 = a^2 + b^2

so

b^2 = c^2 - a^2

b^2 = 53^2 - 45^2

b^2 = 2809 - 2025

b^2 = 784

b = 28

so  the two diagonals:

24 + 28 = 52 m and 45 + 45 = 90 m

Area of the kite:

A = 52 x 90 / 2

A = 2340 m^2
