Answer:
Length: 28 ft Width: 12 ft
Step-by-step explanation:
So to solve this, we know that perimeter means the sum of all the lengths added together. And we can start by dividing 80 by 4.
80 ÷ 4 = 20
And now, the width must be eight feet less than the length, meaning we just subtract eight from the width, and add eight to the length.
20 - 8 = 12
20 + 8 = 28
L = 28
W = 12
And now we can double check:
12+ 28 + 12 + 28 = 80
Have a great day:)

Solve 9(8 - x) = 3x.
Hello - let's do this step by step. Show your work.
You're asking: 9(8−x)=3x.
Now, simplify both sides of the equation.
9(8−x)=3x
(9)(8)+(9)(−x)=3x (To do that, distribute)
72+−9x=3x
−9x+72=3x
Now, subtract 3x from both sides.
−9x+72−3x=3x−3x
Simplify,
−12x+72=0
After, subtract 72 from both sides.
−12x+72−72=0−72
−12x=−72
Last thing, divide both sides by -12.
-12x/12 = -72/-12
Divide.
Therefore, you have x = 6 as your final answer.
Hello there!
9(8-x)=3x
Use the Distributive Property to distribute 9:
72-9x=3x
Move all the variables to the left side. Be sure to use the opposite operation!
-9x-3x=-72
-12x=-72
Divide both sides by 12 in order to isolate x:
x=6
Hope this helps you!

1Kg of grapes cost 5.80 Meagan buys 700 grames of grapes how much does she pay
Meagan pay 4.60
Step-by-step explanation:
1kg------5.80
700g----X
700x5.80=4.60/1=4.60
Final answer:
To find the cost of 700 grams of grapes, divide the cost of 1 kilogram by 1000 to get the price per gram, then multiply by 700. Meagan pays $4.06 for 700 grams of grapes.
Explanation:
To calculate how much Meagan pays for 700 grams of grapes when 1 kilogram (1000 grams) of grapes costs $5.80, we first find out the cost per gram. Then we multiply the cost per gram by the amount of grams Meagan is buying.
The cost per gram is: $5.80 / 1000 grams = $0.0058 per gram.
So for 700 grams, Meagan pays: $0.0058 per gram × 700 grams = $4.06.
Therefore, the cost of 700 grams of grapes is $4.06.

The answer would be 186.2.
Answer:
The correct answer is 133% of 140 = 186.2
Step-by-step explanation:
Points to remember
X % of Y is given by
(X/100)*Y
To find 133 % of 140
We have to find 133 % of 140,
According to the formula we can write,
133% of 140 = (133/100) * 140
= 1.33 * 140
= 186.2
133% of 140 = 186.2
Therefore the correct answer is 133% of 140 = 186.2

Find the area of a rectangle whose side lengths are 4x*2and 6x*2-3
Answer:
24x^4- 12x^2 or 12x^2 (2x^2-1)
Step-by-step explanation:
We are given the length and width of the rectangle:
Length=l=4x^2
and
Width=w=6x^2-3
The formula for the area of rectangle is:
Area=length*width
Area=l*w
Putting the values of l and w into the formula:
area=(4x^2 )(6x^2-3)
=24x^(2+2)-12x^2
=24x^4- 12x^2
It can also be written as: taking 12x^2 as common:
=12x^2 (2x^2-1)

i^223 is equal to?
[tex]\(i^{223}\)[/tex] is equal to -i.
To find the value of [tex]\(i^{223}\)[/tex], we can use the cycle of powers of i:
[tex]\(i^1 = i\), \(i^2 = -1\), \(i^3 = -i\)[/tex], and [tex]\(i^4 = 1\)[/tex]
The powers of i repeat every four steps.
Therefore, we can express [tex]\(i^{223}\)[/tex] in terms of [tex]\(i^4\)[/tex]:
[tex]\[i^{223} = (i^4)^{55} \cdot i^3\][/tex]
Since [tex]\(i^4 = 1\)[/tex] and [tex]\(i^3 = -i\)[/tex], we have:
[tex]\[i^{223} = 1^{55} \cdot (-i) = -i\][/tex]
A car rental company charges $29 per day to rent a car and $0.15 per mile driven.
a) Write a rule for the total bill B as a function of the number of miles m the car is driven.
b) What is the bill for a 2-day rental if you drove 205 miles?
Answer:
A) C = 29*d + 0.15*m
B) C = $88.75
Step-by-step explanation:
Givens
Let the cost of the rental = C
Let the most of the daily rental = d
Let the cost of the mileage driven = m
Equation
Cost = 29*d + 0.15*m
C = 29*d + 0.15m
Part B
d = 2
m = 205
C = ?
C = 29*2 + 205*0.15
C = 58 + 30.75
C = $88.75

Please help! Select the correct ordered pairs in the table.
Answer:
(-4, -12) (1, -2) (2, -18)
Step-by-step explanation:
We have a grade 3 polymial function.
We know that the function has a minimum at the point
(-3, -18).
If this is the minimum of the function then this means that when [tex]x <-3[/tex] the function is decreasing and when [tex]x> -3[/tex] the function is growing.
Look in the table for ordered pairs with values of x less than -3.
The only point is (-4, -12).
Then the function has a maximum in ([tex]\frac{1}{3}[/tex], [tex]\frac{14}{27}[/tex])
This means that when [tex]x> \frac{1}{3}[/tex] the function is decreasing and when [tex]x< \frac{1}{3}[/tex] the function is growing.
Search the table for ordered pairs with values of x greater than [tex]\frac{1}{3}[/tex]
We have
(1, -2) (2, -18)
Finally the ordered pairs in which the function decreases are:
(-4, -12) (1, -2) (2, -18)

margie as 5 times as many nickels as quarters. she has a total of $2.00 how many does she have of each coin?
Answer:
4 quarters and 20 nickels
Step-by-step explanation:
4 quarters= 1.00
4x5=20 nickels =1
1+1=2.00
Margie has 4 quarters and 20 nickels, which amounts to $2.00. The solution was found by setting up and solving a system of equations.
Explanation:The question involves solving a system of equations to find out how many nickels and quarters Margie has if she has 5 times as many nickels as quarters and the total value is $2.00. Let's define two variables: n for the number of nickels and q for the number of quarters. Now, we have two equations based on the information provided:
5n = q (Margie has 5 times as many nickels as quarters)0.05n + 0.25q = 2.00 (The total value of nickels and quarters is $2)Substitute the first equation into the second: 0.05(5q) + 0.25q = 2.00, which simplifies to 0.25q + 0.25q = 2.00, meaning that 0.50q = 2.00. Divide both sides by 0.50 to find that q = 4. Since q = 4, we substitute it back into the first equation to find that 5n = q gives us n = 4/5, which results in n = 20. Therefore, Margie has 4 quarters and 20 nickels.
what is the measure of secant dc

__________ = _____ = 4 * 27 = 108 cubes
Vol of cube (1/27)
Step-by-step explanation:
Approximately 108 cubes, each with side lengths of 1/3 unit, can fit into a rectangular prism that has a volume of 4 cubic units.
Explanation:The subject of this question covers volume and dimension within 3D Geometry, particularly recognizing cubic units as a measure of volume. Given a rectangular prism with a volume of 4 cubic units, which is filled with cubes, each with side lengths of 1/3 unit, the idea is to understand how many smaller cubes would fit into the larger prism.
When calculating, we first need to figure out the volume of one small cube: (1/3)^3 = 1/27 cubic units. Then, you would divide the total volume of the rectangular prism by the volume of one of the small cubes: 4 divided by 1/27. This gives approximately 108, meaning around 108 cubes with a side length of 1/3 can fit into a rectangular prism with a volume of 4 cubic units.

Which expression is equivalent to...? Screenshots attached. Please help! Thank you.
Answer:
[tex]4x^{3} y^{2} (\sqrt[3]{4 x y})[/tex]
Step-by-step explanation:
Another complex expression, let's simplify it step by step...
We'll start by re-writing 256 as 4^4
[tex]\sqrt[3]{256 x^{10} y^{7} } = \sqrt[3]{4^{4} x^{10} y^{7} }[/tex]
Then we'll extract the 4 from the cubic root. We will then subtract 3 from the exponent (4) to get to a simple 4 inside, and a 4 outside.
[tex]\sqrt[3]{4^{4} x^{10} y^{7} } = 4 \sqrt[3]{4 x^{10} y^{7} }[/tex]
Now, we have x^10, so if we divide the exponent by the root factor, we get 10/3 = 3 1/3, which means we will extract x^9 that will become x^3 outside and x will remain inside.
[tex]4 \sqrt[3]{4 x^{10} y^{7} } = 4x^{3} \sqrt[3]{4 x y^{7} }[/tex]
For the y's we have y^7 inside the cubic root, that means the true exponent is y^(7/3)... so we can extract y^2 and 1 y will remain inside.
[tex]4x^{3} \sqrt[3]{4 x y^{7} } = 4x^{3} y^{2} \sqrt[3]{4 x y}[/tex]
The answer is then:
[tex]4x^{3} y^{2} \sqrt[3]{4 x y} = 4x^{3} y^{2} (\sqrt[3]{4 x y})[/tex]

A circular pizza with a diameter of 12 inches is cut along radii into three wedge-shaped slices. The measure of two of the central angles are 80 degrees and 130 degrees. What is the number of square inches in the area of the largest slice? (express your answer in terms of pi)
Answer:
A = 15π in²
Step-by-step explanation:
If two of the central angles are 80° and 130°, totalling 210°, then the third central angle must be (360° - 210°), or 150°.
Let's calculate the area of the entire pizza, whose diameter is 12 in and whose radius is therefore 6 in:
A = πr² → A = π(6 in)² = 36π in².
The area of the largest slice, the one with central angle 150°, is
(150/360) times the total area of the pizza:
A = (150/360)(36π) in², or 15π in²

Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
