A landscaper is constructing a rectangular garden with an area of 108 square feet. He draws the garden on paper and represents the length as and the width as (x-1) . Find the length and the width of the garden(x-4). Select all that apply
7 feet
8 feet
9 feet
12 feet
13feet
plssss help
The length and width of the garden is 12 feet and 9 feet respectively.
Given that, length of garden [tex]=(x-1)[/tex]
Width of garden [tex]=(x-4)[/tex]
Area of garden is 108 square feet.
[tex]Area=length*width\\\\108=(x-1)*(x-4)\\\\x^{2} -5x+4=108\\\\x^{2} -5x-104=0\\\\x^{2} -13x+8x-104=0\\\\x(x-13)+8(x-13)=0\\\\(x-13)(x+8)=0\\\\x=13,x=-8[/tex]
Since, side can not be negative.
So we will consider, [tex]x=13[/tex]
Length[tex]=x-1=13-1=12feet[/tex]
Width[tex]=(x-4)=13-4=9feet[/tex]

[tex]x + y + z[/tex]
[tex]x = 70 digree [/tex]
[tex]z = 40digree[/tex]
[tex]find y[/tex]
Answer:
x = 110
y = 110
Step-by-step explanation:
Here, we are going to apply an important triangle property
The sum of opposite interior angles equal the exterior angle of the third side
Thus, we have that;
y = 70 + 40 = 110
As we can see, the third angle in the triangle will be;
180-70-40 = 110
This is because sum of angles = 180
Thus, applying the exterior angle relationship,
x = 70 + 40 = 110
The length of a rectangle is 2yds longer than its width. If the perimeter of the rectangle is 64 yards, find the length and width
Answer:
15 yards = width
length = 17 yards
Step-by-step explanation:
Perimeter = 2 x ( length + breadth)
let x = width
length = 2 + x
64 = 2(x + 2 + x)
64 = 2 (2 + 2x)
divide both sides by 2
32 = (2 + 2x)
solve for x
x = 15 yards = width
length = x + 2 + 15 + 2 = 17 yards

There are 4 consecutive odd integers that sum to 344. Which integers are they?
Answer:
The consecutive odd integers are 83, 85, 87 and 89.
Step-by-step explanation:
x + (x + 2) + (x + 4) + (x + 6) = 344
4x + 12 = 344
4x = 344 - 12
4x = 332
x = 332/4
x = 83
x + 2 = 85
x + 4 = 87
x + 6 = 89

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin. Write the ratio of hours spent practicing violin to hours spent playing softball three different ways.
Given:
Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.
To find:
The ratio of hours spent practicing violin to hours spent playing softball three different ways.
Solution:
We have,
Time spend on Softball = 5 hours
Time spend on Violin = 4 hours
The ratio to hours spent practicing violin to hours spent playing softball is
[tex]\text{Required ratio}=\dfrac{\text{Time spend on Violin}}{\text{Time spend on Softball}}[/tex]
[tex]\text{Required ratio}=\dfrac{4}{5}[/tex]
It can be written as
[tex]\text{Required ratio}=4:5[/tex]
[tex]\text{Required ratio}=4\text{ to }5[/tex]
Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are [tex]\dfrac{4}{5}, 4:5[/tex] and 4 to 5.

1. The number of rabbits on an island is increasing exponentially.
In Year 1 there are 50 rabbits.
In Year 5 there are 72 rabbits.
How many rabbits are there in Year 10?
Answer:
There are approximately 114 rabbits in the year 10
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P=P_o(1+r)^t[/tex]
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
We are given two measurements of the population of rabbits on an island.
In year 1, there are 50 rabbits. This is the point (1,50)
In year 5, there are 72 rabbits. This is the point (5,72)
Substituting in the general model, we have:
[tex]50=P_o(1+r)^1[/tex]
[tex]50=P_o(1+r)\qquad\qquad[1][/tex]
[tex]72=P_o(1+r)^5\qquad\qquad[2][/tex]
Dividing [2] by [1]:
[tex]\displaystyle \frac{72}{50}=(1+r)^{5-1}=(1+r)^{4}[/tex]
Solving for r:
[tex]\displaystyle r=\sqrt[4]{\frac{72}{50}}-1[/tex]
Calculating:
r=0.095445
From [1], solve for Po:
[tex]\displaystyle P_o=\frac{72}{(1+r)^5}[/tex]
[tex]\displaystyle P_o=\frac{72}{(1.095445)^5}[/tex]
[tex]P_o=45.64355[/tex]
The model can be written now as:
[tex]P=45.64355(1.095445)^t[/tex]
In year t=10, the population of rabbits is:
[tex]P=45.64355(1.095445)^{10}[/tex]
P = 113.6
[tex]P\approx 114[/tex]
There are approximately 114 rabbits in the year 10
Two cars leave at the same time from two cities that are 374 miles apart
and travel towards each other. Car 1 travels 50mph and Car 2 travels 60mph. How
long do they travel before they meet?
Answer:
They travel for 3.4 hours before they meet.
Step-by-step explanation:
Given that:
Distance between the cities = 374 miles
Speed of Car 1 = 50 mph
Speed of Car 2 = 60 mph
As the cars are moving towards each other,
Combined speed = 50 + 60 = 110 mph
We know that:
Distance = Speed * Time
374 = 110 * Time
Time = [tex]\frac{374}{110}[/tex]
Time = 3.4 hours
Hence,
They travel for 3.4 hours before they meet.
