You have 50 ft of fencing and want to fence in a rectangular area of 144 ft^2. What are going to
be the dimensions of the rectangular area?
Quadratic equation
Answers
Answer:
16 by 9 feet.
Step-by-step explanation:
We have 50 feet of fencing in total.
Therefore, the perimeter of our area is 50. Perimeter is given by:
[tex]P=2(\ell+w)[/tex]
Substituting 50 for P yields:
[tex]50=2(\ell+w)[/tex]
And dividing both sides by 2 yields:
[tex]\ell+w=25[/tex]
The area of a rectangular is given by:
[tex]A=\ell w[/tex]
Where [tex]\ell[/tex] is the length and [tex]w[/tex] is the width.
We want to enclose 144 feet squared. So, A=144:
[tex]144=\ell w[/tex]
By the perimeter equation, we can subtract a variable, say [tex]\ell[/tex] from both sides. Hence:
[tex]w=25-\ell[/tex]
Now, we can substitute this into our area equation. Therefore:
[tex]144=\ell(25-\ell)[/tex]
Distribute:
[tex]144=25\ell-\ell^2[/tex]
Subtract 144 from both sides:
[tex]-\ell^2+25\ell-144=0[/tex]
Divide everything by -1:
[tex]\ell^2-25\ell +144=0[/tex]
Factor:
[tex](\ell-9)(\ell-16)=0[/tex]
Zero Product Property:
[tex]\ell_1=9\text{ or } \ell_2=16[/tex]
Then it follows that:
[tex]w_1=25-(\ell_1)=25-9=16[/tex]
Or:
[tex]w_2=25-(\ell_2)=25-(16)=9[/tex]
Regardless, the dimensions of the rectangular area will be 16 by 9 feet.
Answer:
p = 2(l +w)
l= p÷2 -w = l= 25 -w
A= l x w =( 25 -W)W= 144
-w^2 +25w-144 =0
-w^2 +9w+16w- 144=0
(-w^2+9w) +(16w- 144) =0
-w(w - 9) + 16(w - 9) =0
(-w +16) = 0 or w - 9 =0
w = 9 or w = 16
so l = 25 - 9 = 16
or l = 25 - 16 = 9
therefore l = 16ft and w= 9ft

Then she earned:
250x + 500yThe inequalities as per minimum and maximum amount the actress earned:
250x + 500y > 2000 ⇒ x + 2y > 8and250x + 500y < 5000 ⇒ x + 2y < 20So the system is:

2ft3 of clay was mixed into 7ft3 of soil containing 55% clay. What is the clay content of the mixture?
Answers
Given:
2 ft³ of clay was mixed into 7 ft³ of soil containing 55% clay.
To find:
Clay content of the mixture.
Solution:
We have,
55% of soil is clay. So,
Clay in soil= 55% of soil
[tex]\text{Clay in soil}=\dfrac{55}{100}\times 7[/tex]
[tex]\text{Clay in soil}=\dfrac{385}{100} [/tex]
[tex]\text{Clay in soil}=3.85 [/tex]
2 ft³ of clay was mixed into the soil. So, the total clay content of the mixture is
[tex]2+3.85=5.85\text{ ft}^3[/tex]
Therefore, the clay continent in the mixture is 5.85 ft³.
What is the range of this function?

B) {y | y ≥ 0}
C) {y | y ≥ 3}
D) {y | y ≥ -3}
Answers
Greetings.
The range is the set of y-value.
The range starts from the minimum point to maximum point.
Our minimum point starts at 0 and maximum point starts less than infinity.
Therefore the range is 0<=y<+inf
However, we do not often write that, although it is right.
Therefore we write as y≥0
