shorter side : longer side = 3 : 7


Equate 3 parts tp 9 inches:

3 parts = 9 inches


Find 1 part:

1 part = 9 ÷ 3 = 3 inches


Find 7 parts:

7 parts = 3 x 7 = 21 inches


Area = Length x Width = 21 x 9 = 189 in²


Answer: The longer side is 21in and the area is 189 in²

Take the length of the shortest side divide that by the ratio of the shortest side 9/3 =3

Take that number 3 and multiply it by seven.
3*7=21

The shorter side is 9 inches, and the longer side is 21 inches.

To find the area, multiply 21 by 9.
The area is 189 inches

Write a function to represent the set of ordered pairs.<br> {(2, 2), (3,7). (4, 14), (5,23)}
MrMuchimi

Answer:

Step-by-step explanation:

The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function

The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a

function

The set of ordered pairs {(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)} is a function

The set of ordered pairs {(−3 , 7) , (1 , 2) , (4 ,−2) , (12,−4)} is a function

An ordered pair represents a relationship between two values

The first value is the input the second value is the output

1. A relation is a set of inputs and outputs

2. A function is a relation with one output for each input

3. All functions are relations

{(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)}

∵ Each x-coordinate in each ordered pair has only one y-coordinate

∴ The relation above is a function

The set of ordered pairs {(1 , 7) , (−1 , 7) , (8 , −6) , (−3 , 2)} is a function

{(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)}

∵ The x-coordinate 4 has two values of y (7 and -6)

∴ The relation above is not a function

The set of ordered pairs {(4 , 7) , (−1 , 2) , (4 , −6) , (−3 , −2)} is not a

function

{(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)}

∵ Each x-coordinate in each ordered pair has only one y-coordinate

∴ The relation above is a function

The set of ordered pairs {(3 , 7) , (−1 , 2) , (−4 , −2) , (−3 , −2)} is a function

{(−3 , 7) , (1 , 2) , (4 ,−2) , (12,−4)}

∵ Each x-coordinate in each ordered pair has only one y-coordinate

∴ The relation above is a function

The set of ordered pairs {(−3 , 7) , (1 , 2) , (4 ,−2) , (12,−4)} is a function

A train travels 3.5 kilometers on a straight track with a grade of 1 degree 10 minutes. What is the vertical rise of the train i
user100 [1]
I'm pretty sure this is Triangle stuff, with Sin, Cos + Tan, etc.

I can't remember it all I'm afraid, but the angle will be the 1 degree, 10 minutes - the Hypotenuse side will be the 3.5 km
