Are rectangular garden has a perimeter of 280 feet the north side of the garden is 90 feet what is the length of the inside of t
attashe74 [19]

The length of the inside of the garden is<u> 50 feet.</u>

What is perimeter ?

A perimeter is a closed path that covers, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter.

There are various practical applications for calculating the perimeter. A calculated perimeter is the length of fencing needed to completely encircle a yard or garden. The perimeter (circumference) of a wheel/circle describes how far it will roll in one revolution. Similarly, the amount of string wrapped around a spool is proportional to the spool's perimeter; if the string length were correct, it would equal the perimeter.

Given :

The rectangular garden has a perimeter of 280 feet

breadth = 90 feet

Let the length be x.

Therefore according to the question,

2( 90 + x ) = 280

=> 90+ x = 140

=> x = 50

Find the tangent of ∠I.
Nady [450]

Answer:

tanI = \frac{\sqrt{70} }{5}

Step-by-step explanation:

We require to calculate GH using Pythagoras' identity in the right triangle.

GH² + GI² = HI²

GH² + 5² = (\sqrt{95} )²

GH² + 25 = 95 ( subtract 25 from both sides )

GH² = 70 ( take square root of both sides )

GH = \sqrt{70}

Then

tanI = \frac{opposite}{adjacent} = \frac{GH}{GI} = \frac{\sqrt{70} }{5}

Answer:

<em>Consistent independent</em>

<em>Consistent dependent</em>

<em>Inconsistent</em>

Step-by-step explanation:

<u>Consistent and Inconsistent Linear Systems</u>

A system of equations is consistent if it has at least one solution. If the solution is unique, then the system is consistent independent, otherwise is consistent dependent, i.e., it has an infinite number of solutions.

When there is no solution for the system, the lines of each equation are parallel but not coincident. A consistent dependent has two non-parallel lines, and a consistent independent system has only one line, i.e. the same line represents both equations.

Two lines are parallel if they have the same slope. To find the slopes, we represent the equations in slope-intercept form:

y = mx + b

Where m is the slope and b is the y-intercept.

Consider the system:

4x + y   = 8

x  + 3y = 8

Rearranging both equations:

y = -4x + 8

y = -1/3 x + 8

The slopes of the lines are -4 and -1/3 respectively, since they are different, the system is consistent independent.

Consider the system:

-4x + 6y = -2

2x - 3y = 1

Rearranging both equations:

y = 4/6 x - 2/6 = 2/3 x - 1/3

y = 2/3 x - 1/3

Both equations are exactly the same, thus the system is consistent dependent.

Consider the system:

5x - 2y = 4

5x - 2y = 6

Rearranging both equations:

y = 5/2 x - 2

y = 5/2 x - 3

These lines are parallel but not coincident. Thus this system is inconsistent.
