Answer: 1,600 sq units.
Step-by-step explanation: The perimeter of a square field is 160. When finding the perimeter of a square, all sides are the same, so you're adding four sides that have the same number to make 160. You can add 40 four times to make 160, so that gives us a hint of what all the square's sides are, which are 40. To find the area of a square, you need to multiply one side by the other. All sides of the square are 40, so we'll multiply 40 two times to make 1,600 sq units. Therefore, 1,600 sq units is your answer.
Have a great day! :)
how do I convert 216 in percentage
Answer: 21600
216 as a percentage of certain number x can be calculated by dividing 216 by x, and multiplying the result by 100. For example, 216 as a percentage of 10 = (216 / 10) x 100% = 2160%.

Mr. Blue's first year salary is $30,000 and it doubles each year. What is the explicit rule for the sequence in simplified form?
What is the recursive rule?
Mr. Blue' salary is an illustration of a geometric sequence
The explicit rule of Mr. Blue 's salary is an = 30000 * 2^(n - 1)The recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000How to determine the explicit formula?Mr. Blue's salary is a geometric sequence with the following parameters:
First term, a1 = 30000
Rate, r = 2
The explicit rule is calculated as:
an = a1 * r^(n - 1)
This gives
an = 30000 * 2^(n - 1)
How to determine the recursive formula?The common ratio is calculated as:
r = an+1/an
Substitute 2 for r
2 = an+1/an
Cross multiply
an+1 = 2an
Hence, the recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000

A perimeter of a square field is 200, what is the area of that field?
Answer:
2500
Step-by-step explanation:
The perimeter is given by the formula :
P = 4L (L is length)
We rearrange the equation to get L as the subject:
L = P÷4
L = 200÷4
L = 50
The area of a square is given by the formula :
A = L²
A = 50²
A = 2500

Answer:
8.25 min
Step-by-step explanation:
1600 m / 5.5 min = pace
2400 / (1600 / 5.5 ) = 8.25 min

The base of a hemisphere is circle of radius (r) equal as the radius of the sphere
Given,
hemisphere = 15
hight = 100
so, 100 - 15 = 85
a hemisphere is half of the sphere so to get a hemisphere from the sphere you divide by 2. the hight of the hemisphere is 15 feet so subtract that from the total of the 100 and you get 85.

Danita is working on a new sculpture. It will be 2 meters tall when she is finished. Will the sculpture fit in a room with a 300-centimeter high ceiling? Explain.
Answer:
yes; 2 m = 200 cm
Step-by-step explanation:
The SI prefix "centi-" signifies 1/100. That is 300 cm = 300/100 m = 3 m.
If the ceiling is 3 meters high, a sculpture that is 2 meters tall will have no difficulty fitting into the room.
Seven more than a number is less than 18
Answer:
The first thing to do is translate the sentence into mathematical notation.
"no more than" means "less than or equal to" which is written as ≤
"seven less than a number" means we are subtracting 7 from a number. We don't know what the number is, so we can use a variable (like n) for the number. So "seven less than a number" becomes n - 7.
The whole thing becomes 12 ≤ n - 7.
To solve for n, we can add 7 to both sides.
19 ≤ n.
19 is less than or equal to n, which means the smallest (minimum) value of the number is 19.
We could also do it without an inequality:
If 12 is 7 less than a number, then the number is 19, because 19-7=12. If we chose a smaller number, like 18, then 7 less than 18 is smaller than 12, which is not allowed (12 is no more than 7 less than the number). So the smallest possible value of the number is 19.
Let the number be p.
Next, "seven times p" can be written like so:-
[tex]\pmb{7p}[/tex]
This expression is less than 18:-
[tex]\bigstar{\boxed{\pmb{7p < 18}}}[/tex]
note:-Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x?
y=4+x
y = x − 4
y = 4 · x
y = x ÷ 4
Answer:y=4+x
Step-by-step explanation:
You are adding gallons not *,/,-,. So it's y=4+x.
The required equation is y = 4 + x. The correct answer would be an option (A).
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Jayne stopped for gas before embarking on a road trip. There were already 4 gallons of gas in the tank.
As per the question, the required equation would be as:
y = 4 + x
This equation relates the total amount of gasoline in the tank, y, to the number of gallons that she put in the tank, x. The total amount of gasoline in the tank, y, is equal to the number of gallons that she put in the tank, x, plus the 4 gallons that were already in the tank.

Which expression is equivalent to the expression shown below?
-9.25(2n-3) - 8n
A. -18.5n + 19.75
B. 55.5n+ 27.75
C. 26.5n + 19.75
D. 27.75 -26.5n
Answer:
option D
Step-by-step explanation:
Distribute (-9.25) to 2n and (-3). When we multiply (-9.25) and 2n, we get -18.5n and when we multiply (-9.25) and (-3) we get 27.75.
-9.25(2n - 3) - 8n = -9.25*2n - (-9.25) *3 - 8n
= -18.50n + 27.75 -8n
= -18.5n - 8n + 27.75
Combine like terms. Here (-18.5n) and (-8n) are like terms
= -26.5n + 27.75
Mr. Jones is building the garage shown below. What is the volume of the garage?
Answer: 891 ft³
Step-by-step explanation:
We can break the garage into two different parts. The roof, triangular, and the rest, rectangular. I will start by solving for the rectangular part.
V = L * W * H
V = 12 ft * 9 ft * 7.5 ft
V = 810 ft³
Now, I will solve for the triangular part, the roof. First, 9 ft - 7.5 ft = 1.5 ft, so the height of just the roof is 1.5 ft.
V = [tex]\frac{L * W * H}{2}[/tex]
V = [tex]\frac{12 * 9* 1.5}{2}[/tex]
V = [tex]\frac{162}{2}[/tex]
V = 81 ft³
Lastly, I will add the two different parts together.
810 ft³ + 81 ft³ = 891 ft³
Which of the following is the main
reason people buy auto insurance?
A. They want to be covered in case their home starts on
fire.
B. It is not expensive and easily affordable.
C. It is required by law in any state in America.
D. It is very expensive and hard to finance.
Haven't learned this yet.
Explanation:
Most states (but not all) require liability insurance at minimum. This covers injury and property damage to the person you accidently hit. It likely does not cover you personally so you'd need other insurance for that.
States like Iowa, New Hampshire, and Ohio offer exemptions from insurance if you can show you are responsible with money. Meaning that if you have a steady income and are smart with money, then you likely would be able to pay off any future accident without needing insurance. Though the damages might get wildly expensive, so a liability policy isn't always a bad thing.

The factor of the polynomial, the area of the pool and the simplified expression are all algebraic expressions
How to simplify the expressions?Factor of the polynomial
The polynomial is given as:
2x^3 + 6x^2 + 6x + 18
Factor out 2
2x^3 + 6x^2 + 6x + 18 = 2(x^3 + 3x^2 + 3x + 9)
Factorize
2x^3 + 6x^2 + 6x + 18 = 2(x^2(x + 3) + 3(x + 3))
Factor out x + 3
2x^3 + 6x^2 + 6x + 18 = 2(x^2 + 3)(x + 3)
Expand
2x^3 + 6x^2 + 6x + 18 = (2x^2 + 6)(x + 3)
Hence, 2x^2 + 6 is a factor of the polynomial 2x^3 + 6x^2 + 6x + 18
The length of the pool
The given parameters are:
Area = 2x^3 - 29x + 12
Width = x + 4
The length is calculated as:
Length = Area/Width
This gives
Length = 2x^2 - 29x + 12/x + 4
Factorize the numerator
Length = (2x^2 - 8x + 3)(x + 4)/x + 4
Cancel out x + 4
Length = 2x^2 - 8x + 3
Hence, the length of the pool is 2x^2 - 8x + 3
Simplify the expression
The expression is given as:
(3s^2 - 2s + 1) [tex]\div[/tex] (s^2 - s + 2)
Evaluate the quotient
3 + (s - 5)/(s^2 - 5 + 2)
