The width of a rectangle is 6 kilometers less than twice its length. if its area is 108 square​ kilometers, find the dimensions of the rectangle.

Answers

Answer 1
Let x = the length 
2x - 6 = the width as given in the description.

Area of a rectangle is length * width. Now we plug in.

108 = x(2x - 6)
108 = 2x² - 6x

We are going to get all terms on the same side and factor. 

2x² - 6x - 108 = 0

Factor out and divide each term by a GCF of 2 to get: 

x² - 3x - 54 = 0

x² + 6x - 9x - 54 = 0
x(x + 6) - 9(x + 6) = 0

Your factors are (x + 6)(x - 9) = 0. Now we set each binomial equal to zero. This gives us x = - 6 and x = 9. Distance cannot be measure in negative numbers so we know to use x = 9 to find our measurements.

The length (x) is 9 kilometers. The width (2x - 6) is 12 kilometers when you plug in 9 where the x is. 
Answer 2

The dimensions of the rectangle are [tex]\( \boxed{9 \text{ km} \times 12 \text{ km}} \)[/tex].

Let's denote the length of the rectangle as [tex]\( l \)[/tex] kilometers, and its width as [tex]\( w \)[/tex] kilometers.

From the problem statement, we have two pieces of information:

1. The width is 6 kilometers less than twice the length:

  [tex]\[ w = 2l - 6 \][/tex]

2. The area of the rectangle is 108 square kilometers:

  [tex]\[ lw = 108 \][/tex]

Now we can substitute the expression for \( w \) from the first equation into the second equation:

[tex]\[l(2l - 6) = 108\][/tex]

Expand and simplify the equation:

[tex]\[2l^2 - 6l = 108\][/tex]

Subtract 108 from both sides to set the equation to zero:

[tex]\[2l^2 - 6l - 108 = 0\][/tex]

Divide every term by 2 to simplify:

[tex]\[l^2 - 3l - 54 = 0\][/tex]

Now, we'll solve this quadratic equation using the quadratic formula, [tex]\( l = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)[/tex], where [tex]\( a = 1 \)[/tex], [tex]\( b = -3 \)[/tex], and [tex]\( c = -54 \)[/tex]:

[tex]\[l = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-54)}}{2 \cdot 1}\][/tex]

[tex]\[l = \frac{3 \pm \sqrt{9 + 216}}{2}\][/tex]

[tex]\[l = \frac{3 \pm \sqrt{225}}{2}\][/tex]

[tex]\[l = \frac{3 \pm 15}{2}\][/tex]

This gives us two possible solutions for [tex]\( l \)[/tex]:

[tex]\[l = \frac{18}{2} = 9 \quad \text{or} \quad l = \frac{-12}{2} = -6\][/tex]

Since length cannot be negative, we take [tex]\( l = 9 \)[/tex] kilometers.

Now, substitute [tex]\( l = 9 \)[/tex] back into the expression for [tex]\( w \)[/tex]:

[tex]\[w = 2l - 6 = 2 \cdot 9 - 6 = 18 - 6 = 12\][/tex]

Therefore, the dimensions of the rectangle are:

- Length [tex]\( l = 9 \)[/tex] kilometers

- Width [tex]\( w = 12 \)[/tex] kilometers

To verify, calculate the area:

[tex]\[l \times w = 9 \times 12 = 108 \text{ square kilometers}\][/tex]

Since this matches the given area, the dimensions [tex]\( l = 9 \)[/tex] kilometers and [tex]\( w = 12 \)[/tex] kilometers are correct.

Thus, the dimensions of the rectangle are [tex]\( \boxed{9 \text{ kilometers} \times 12 \text{ kilometers}} \)[/tex].

The perimeter of a rectangular floor is 50 feet. find the dimensions of the floor if the length is four times the width.

Answers

length is 20 
width is 5 

let me know if you need more details 

The dimensions of the rectangle are width = 5 feet and length = 20 feet.

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the length and width.

The perimeter of a rectangle = 2(L + W)

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that the perimeter of a rectangular floor is 50 feet.

The length is four times the width.

Let the width of the rectangle is x

So the length of the rectangle = 4x

The perimeter of a rectangle = 2(L + W)

50 = 2(4x + x)

50 = 2(5x)

50 = 10x

10x = 50

x = 50 /10

Apply the division operation,

x = 5

So the length of the rectangle = 4(5) = 20 feet

Therefore, the dimensions of the rectangle are width = 5 feet and length = 20 feet.

What is the total amount and the amount of interest earned on $6,500 at 6% for 25 years?

Answers

Answer:

Total amount earned after 25 years=$27,897.16

Step-by-step explanation:

Step 1: Express formula for calculating total amount

The total amount after 25 years can be expressed as;

A=P(1+r)^n

where;

A=total amount after 25 years

P=principal amount

r=annual interest rate

n=number of years

Step 2: Substitute values in the expression

In our case;

P=$6,500

r=6%=6/100=0.06

n=25 years

replacing in the original expression;

A=6,500(1+0.06)^25

A=27,897.16

Total amount earned after 25 years=$27,897.16

Final answer:

The total amount after 25 years will be $27,897.16, and the amount of interest earned on a $6,500 investment at a 6% annual interest rate will be $21,397.16.

Explanation:

To calculate the total amount and interest earned on $6,500 at 6% for 25 years, we'll assume that the interest is compounded annually. The formula to calculate the total amount with compound interest is:

A = P(1 + r/n)^(nt)

Where:

A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (in decimal).n is the number of times that interest is compounded per year.t is the time the money is invested or borrowed for, in years.

Let's plug the values into the formula:

A = $6,500(1 + 0.06/1)^(1*25)

A = $6,500(1 + 0.06)^25

A = $6,500(1.06)^25

A = $6,500 * 4.29187072

A = $27,897.16

The total amount after 25 years will be $27,897.16.

To find the interest earned, subtract the principal from the total amount:

Interest = A - P

Interest = $27,897.16 - $6,500

Interest = $21,397.16

The amount of interest earned will be $21,397.16.

At 7 a.m. Gene left Austin and headed south at 10 miles per hour. At 8 a.m. Anne left from the same place and headed south on the same road. If Anne was 60 miles ahead by 3 p.m. on the same day, what was her speed?

Answers

The answer is 20 miles

Anne's speed is 20 miles per hour. If she returned home by the same path 7 hours and 30 minutes after she left, her average speed for the entire trip is 18.67 miles per hour while her average velocity is zero.

To answer this question, we need to calculate Anne's speed based on the information given. Gene started at 7 a.m. traveling at 10 miles per hour. By the time Anne starts at 8 a.m., Gene has already covered 10 miles (since he travels for 1 hour). The time from 8 a.m. to 3 p.m. is 7 hours. Both Anne and Gene travel the same path for these 7 hours, but Anne is 60 miles ahead of Gene by 3 p.m. Therefore, we need to calculate the total distance Gene traveled in 8 hours, add 60 miles to that distance, and then divide by 7 to find Anne's speed.

First, we determine Gene's total travel distance by 3 p.m., which is 10 miles/hour * 8 hours = 80 miles. Anne is 60 miles ahead, meaning she traveled 80 miles + 60 miles = 140 miles in 7 hours. Thus, Anne's speed is 140 miles \/ 7 hours = 20 miles per hour.

For part (c), if Anne returned home by the same path 7 hours and 30 minutes after she left, the total trip time would be 15 hours (7 hours to 3 p.m. and another 7 hours and 30 minutes back). Since the round trip distance is 140 miles out and 140 miles back, the total distance is 280 miles. Her average speed is total distance divided by total time, hence 280 miles / 15 hours = 18.67 miles per hour. The average velocity for the round trip is zero because she ends up at the starting point, so the overall displacement is zero.

Karen makes $5 per hour baby-sitting and $12 per hour giving music lessons. one weekend, she worked a total of 18 hours and made $139. how many hours did she spend baby-sitting?

Answers

Let the number of hours she spent in baby- sitting is x

and the number of hours she spent in music lessons is y.

Now, we have been given that she worked a total of 18 hours. Hence, we have

[tex]x+y=18\\ y=18-x...............................(1)[/tex]

And she made $139. Thus, we have

[tex]5x+12y=139..............................(2)[/tex]

Substituting the value of y from equation 1 in 2, we get

[tex]5x+12(18-x)=139\\ 5x+216-12x=139\\ -7x=-77\\ x=11[/tex]

Therefore, she spent 11 hours in baby-sitting.

Final answer:

Karen spent 11 hours baby-sitting and 7 hours giving music lessons.

Explanation:

Let x be the number of hours spent baby-sitting, and let y be the number of hours spent giving music lessons.

We are given the following information:


 Karen makes $5 per hour baby-sitting, so she earned 5x dollars from baby-sitting.
 Karen makes $12 per hour giving music lessons, so she earned 12y dollars from giving music lessons.
 She worked a total of 18 hours, so x + y = 18.
 She made a total of $139, so 5x + 12y = 139.



We can now set up a system of equations:


 x + y = 18
 5x + 12y = 139


To solve this system, we can use substitution or elimination method. Let's use the elimination method:


 Multiply the first equation by 5 to make the coefficients of x the same: 5x + 5y = 90.
 Subtract this new equation from the second equation: (5x + 12y) - (5x + 5y) = 139 - 90.
 Simplify both sides of the equation: 7y = 49.
 Divide both sides of the equation by 7: y = 7.
 Substitute y = 7 into the first equation: x + 7 = 18.
 Solve for x: x = 11.

Therefore, Karen spent 11 hours baby-sitting and 7 hours giving music lessons.

each of the circles below has an area of 196 pi square units find the perimeter of the rectangle

Answers

Answer:

Step-by-step explanation:

Alright lets get started.

We have given the area of each circle as 196 pi square units.

since the area of the circle =[tex]\pi*radius^2[/tex]

so,the radius of the circle :

[tex]196\pi =\pi r^2[/tex]

[tex]r^2=196[/tex]

[tex]r=14[/tex]

therefore the diameter of the circle will be [tex]2*radius=2*14=28[/tex]

the perimeter of the rectangle=[tex]2*(length+ width)[/tex]

the length of the rectangle will be addition of diameters of the circle=[tex]28+28=56[/tex]

breadth of the rectangle is equal of the diameter =28

Perimeter of the rectangle =[tex]2*(56+28)=168[/tex]

Answer  168 units.

The perimeter of the given rectangle is 168 units

Given that area of each of the circles are [tex] 196 \pi [/tex] sq units and we know that the area of circle [tex]=\pi r^{2}[/tex] using this radius of the circle will be

[tex]\pi r^{2} =196\pi\\ r^{2} = 196\\ \\ r=14[/tex]

So, the diameter of the circle is twice the radius which is

[tex]2\times r\\ 2\times 14 =28 [/tex]

Here we can see that length of rectangle is equal to twice the diameter of the circle and breadth is equals to twice the radius

[tex]length= 28+28=56[/tex]

[tex]breadth = 2\cdot14=28[/tex]

How to find the perimeter of the given rectangle ?

To find the perimeter we use the formula

Perimeter of rectangle = [tex]2\cdot(length + breadth)[/tex]

On solving we get ,

[tex]2\cdot(56 +28)\\ 168 units[/tex]

Therefore, The perimeter of the given rectangle is 168 units

(05.07 mc) mandy needs to paint all the faces and the base of a model pyramid she made for her history project. the dimensions of the pyramid are shown here. what is the total surface area of the pyramid? a square pyramid is shown. the side of the square is 10 inches. the height of the triangular faces is 9 inches.

Answers

To find the area of the square pyramid you will consider the shapes that make up the net of the pyramid (what it looks like when it is unfolded).

There are 4 congruent (same size and shape) triangles and a square.

The area of the square is
A = bh
     10 in x 10 in
A = 100 square inches.

The area of one triangle is
A = 1/2bh
    1/2 x 10 in x 9 in
A = 45 square inches

45 square inches x  4 (for the 4 triangles)

180 square inches of triangles

180 + 100 = 280

The total surface area of the square pyramid is 280 square inches.

Answer:

280

Out of the 180 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 of those students also signed up for canoeing.

Use a two-way table to organize the information and answer the following question:

Approximately what percentage of students signed up for neither canoeing nor trekking?

72%
40%
54%
98%

Answers

There are 72 students that signed up for canoeing, and 23 students that signed up for trekking. 13 of these 23 students also signed up for canoeing.

Use the following equation to find the amount of people that signed up for an activity:

[tex]72 + 23 - 13 = 82[/tex]

82 students signed up for canoeing or trekking.

Subtract this total from the total amount of students to find the total that did not sign up for an activity:

[tex]180 - 82 = 98[/tex]

Divide this number by the total amount of students in the camp:

[tex]98 \div 180 = 0.54[/tex]

Multiply this decimal by 100 to convert into a percentage:

[tex]0.54 * 100 = 54[/tex]

54% of students did not sign up for neither canoeing nor trekking.
