Hannah has a small square shaped garden with an area of 196 square feet. If she wants to put a fence around the garden, how many feet of fencing will she need?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
A square is a quadrilateral that has the same length on every side.
The area of the garden is 196 square feet. To find the area of a garden, you have to multiply the length times the width. Since you know that both widths are the same, you can simply just calculate the square root of 196. The square root of 196 is 14. So you know that one side is 14 feet in length.
Now you will need to find the perimeter. The perimeter of any polygon is the lengths of all sides added up. Since there are 4 sides on a square, and each side is the same length, you can just add 14, 4 times. 14+14+14+14 equals 56. So the perimeter of the garden is 56 feet.
Hannah will need 56 feet of fencing.

she needs to put 56 feet of fencing materials around ground
What is square?A quadrilateral which has four equal sides and four equal angles is known as a square.
According to the question,
To find the fencing material means to calculate the length around the square garden, or the perimeter of the square shaped garden.
Area , A is given as 196 square feet.
Formula for Area of a square (A )= Side × side
196 = side × side
This can be written as
Side × Side = 196
[tex]side^{2}[/tex] = 196
Take the square root of both sides,
[tex]\sqrt{side^{2} }[/tex] = [tex]\sqrt{196}[/tex]
side = 14 feet
The perimeter of a square can be calculated, P = 4(s), because all the four
sides are equal
P = 4 × side
= 4 × 14
= 56 feet
Hence, she needs 56 feet of fencing materials.

Please let me know if you have any question
Answer:
1.5
Step-by-step explanation:
First find 1 3/4 and 1 1/6 as an improper fraction. 1 3/4 = 7/4 because 1 times 4 plus three. 1 1/6 = 7/6 because 1 times 6 plus 1, so now you have 7/4 divided by 7/6. You change 7/6 to it's reciprocal, which is 6/7. Now it's like multiplication with fractions. 7*6=42. 4*7=28, so it's 42/28.
Now we want to simplify. It can be simplified to 1 1/2, which is also 1.5. Hope this helps.

Answer:
Hello! :) I hope I am correct!!
Step-by-step explanation:
The answer would be: x=9
(Below is how I got ‘x=9’)
Here are the steps to solve this problem/equation.
1. Simplify both sides to the equation.
⇒10x +-21=61
⇒10x -29=61
2. Now add 29 to both of the sides
⇒ (you will end up with: 10x=90

By the definition of angles, the sum of the measures of angles 1 and 2 is 180 degrees. Likewise, the sum of the measures of angles is 180 degrees. By the property, mAngle1 + mAngle2 = mAngle3 + mAngle2. Subtract the measure of angle from each side. You get mAngle1 = mAngle3, or Angle1 Is-congruent-to Angle3, by the definition of congruence
Answer: Supplementary, 3 and 2, substitution, 2.
Step-by-step explanation: just did it .
The ∠1 is congruent to ∠3 by definition of congruency.
What is an angle?An angle is formed from the intersection of two lines. Types of angles are acute, obtuse and scalene.
m∠1 + m∠2 = 180° (given)
m∠2 + m∠3 = 180° (given)
Hence:
m∠1 + m∠2 = m∠2 + m∠3 (equality property)
Subtract m∠2 from both sides to get:
m∠1 = m∠3

a lightbulb manufacturer would like to increase production from 1.4 million to 3.9 million lightbulbs per year. find the percent increase of the production expectation. ( round your answer to one decimal place)
Answer:
The percentage increase of the production expectation to 1 decimal place is 178.6%
Step-by-step explanation:
Here in this question, we are interested in finding the percentage increase in the production capacity of the hypothetical company;
We can make or have a formula for this to make our workings easier;
% increase = (new value - old value)/old value * 100%
From the question;
The old value is the former productive capacity which is 1.4 million
The new productive capacity is 3.9 million
Thus;
The percentage increase in the production capacity would be;
(3.9 million - 1.4 million)/1.4 million * 100%
= 2.5 million/1.4 million * 100% = 178.57%
But the question asks we should have our answer in one decimal place;
Thus; 178.57% becomes 178.6%

Answer:
the height of the candle before it is lit
Step-by-step explanation:
When the candle is first lit, time is 0.
At tome 0, x = 0 and the height is -0.25(0) + 5 = 5.
The height is 0 at time zero, so the constant term, 5, represents the height of the candle before it is lit.
A playing card has a perimeter of 28 centimeters. Its area is 45 square centimeters. What are the dimensions of the playing card?
Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
[tex]A=lb[/tex]
[tex]45=lb\\\\l=\dfrac{45}{b}\ .....(1)[/tex]
Perimeter,
[tex]P=2(l+b)\\\\28=2(l+b)\\\\14=(l+b)\ ....(2)[/tex]
Put the value of l from equation (1) to equation (2). So,
[tex]14=\dfrac{45}{b}+b\\\\14=\dfrac{45+b^2}{b}\\\\14b=45+b^2\\\\b^2-14b+45=0\\\\b^2-9b-5b+45=0\\\\b(b-9)-5(b-9)=0\\\\b=5\ cm, 9\ cm[/tex]
Put the value of b in equation (1),
If b = 5 cm
[tex]l=\dfrac{45}{5}=9\ cm[/tex]
If b = 9 cm
[tex]l=\dfrac{45}{9}=5\ cm[/tex]
So, the dimensions of the playing card is 9 cm by 5 cm.
if p(x)= 2x^2 -4x and q(c) = x-3, what is (p•q)(x)
Answer:
2x^3 - 10x^2 +12x
Step-by-step explanation:
p(x)= 2x^2 -4x
q(x) = x-3
(p•q)(x) = (2x^2 -4x) * ( x-3)
FOIL
first 2x^2 *x = 2x^3
outer 2x^2 *-3 = -6x^2
inner -4x *x = -4x^2
last -4x*-3 = 12x
Add together
2x^3 -6x^2 -4x^2 +12x
Combine like terms
2x^3 - 10x^2 +12x
Answer:
(p•q)(x) = 2x² - 16x + 30Step-by-step explanation:
p(x) =2x² - 4x
q(x) = x - 3
In order to find (p•q)(x) substitute q(x) into p(x) that's replace every x in p(x) by q(x)
That's
(p•q)(x) = 2( x - 3)² - 4( x - 3)
Expand the terms
That's
(p•q)(x) = 2( x² - 6x + 9) - 4x + 12
= 2x² - 12x + 18 - 4x + 12
Group like terms
(p•q)(x) = 2x² - 12x - 4x + 18 + 12
Simplify
We have the final answer as
(p•q)(x) = 2x² - 16x + 30

would you rather have cheez its to cover a rectangle with a length of 9 and a perimeter of 22 or a length of 5 and a perimeter of 20
Answer:
A length of 5 and a perimeter of 20
Step-by-step explanation:
Personally, I'm lactose intolerant so I wouldn't take any Cheez-Its, but oh well.
Everyone wants the most Cheez-its, right? So we need to find the rectangle with the greatest area.
Let's look at the first one, a rectangle with a length of 9 and a perimeter of 22.
The perimeter of a rectangle can be expressed as [tex]2l+2w[/tex], where l is the length and w is the width.
We know the length and area, so let's solve for w (the width).
[tex]2\cdot9+2w=22\\\\18+2w=22\\\\2w=4\\\\w=2[/tex]
So the width is 2. The area of a rectangle is the length times the width.
[tex]9\cdot2=18[/tex]
So the first rectangle has an area of 18.
Using the same concept for the second statement, a length of 5 and a perimeter of 20, we can find the area.
[tex]2l+2w=20\\\\2\cdot5+2w=20\\\\10+2w=20\\\\2w=10\\\\w=5\\\\5\cdot5=25[/tex]
So the area of the second one is 25.
The greatest area is 25, so you'd want this one.
Hope this helped!
