<h2>Answer:</h2>

An ordered pair is:

a set of points that pair input values with output values

<h2>Step-by-step explanation:</h2>

<u>ordered pair--</u>

In mathematics an ordered pair is a pair of objects in which the order in which they need to be paired are taken care of.

It is represented in the form of: (x,y)

where x is the input value of the relation and y is the output value of the relation.

It is also known a 2-tuple.

The ordered paired is basically used to locate a point in a coordinate plane.

A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?

bezimeni [28]

Answer: 17160 feet

Step-by-step explanation:

We know that 5280 feet = 1 mile

So all we have to do is multiply 3 1/4 by 5280

Let's split the 3 and 1/4 up to make the multiplication easier

3×5280=15840

$\frac{1}{4}$ ×5280= $\frac{5280}{4} =1320$

Now add them together

15840+1320=17160

Find the value of x.<br> A) 55<br> B) 60<br> C) 70<br> D) 125

Anna11 [10]

Answer:

x = 70°

Step-by-step explanation:

The given triangle has 2 equal sides and is therefore isosceles.

The base angles are equal, both 55°

To find x subtract the sum of the 2 angles from 180

x = 180° - (55 + 55)° = 180° - 110° = 70°

Please help geometry

sveta [45]

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
