A square of 81cm² is cut to make two rectangles, A and B
The ratio of area A to are B is 2:3
Work out the dimensions of A and B
Answers
Answer:
Length of A: 9
Width of A: 6
Length of B: 9
Width of B: 3
Step-by-step explanation:
If you look at the diagram, you can see that the length of rectangles A and B are the same, and are also the same as they were in the original square. We can find the length of each side by finding the square root of the area of the square to give us the length and width of the square which is 9. Now that we know that the length of both rectangles A and B, we can find the width of both rectangles by taking 9, and splitting it into 3 portions of 3. Since the ratio of area is 2:1, we could also do this with the area, but since we know the lengths are the same, we know the widths are proportional to the area. Using the ratio of 2:1, and the 3 portions of 3, you can combine 2 of these portions to get 6, and since the ratio 6:3 is proportional to 2:1, these measurements can be used as the width of each rectangle. Thus, the answer given above.
Answer:
Length of A: 9
Width of A: 6
Length of B: 9
Width of B: 3

Explanation:
We'll add up the values in the bottom row of the table.
A value like +150 is the same as simply saying 150
The negatives stick around.
Adding up the values in that row gets us
150 + (-50) + 400 + 300 + (-175) + (-250) = 375
This indicates that over the entire 6 month period, the overall change is +375
---------
In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.
We can then say:
x + 375 = 1500
x = 1500-375
x = 1125
She initially invested $1125

Part 1: Which compound does C represent?

Part 3: Explain how the elements that form it are conserved during the carbon cycle. Use complete sentences to explain your answer.
Justify how this compound was created from a recycling of carbon in the carbon cycle. Use complete sentences to explain your answer.
Answers
The process that arrow C signifies is the burning of fossil fuels in order to present carbon dioxide into the atmosphere. The mentioned procedure in the carbon cycle is comparatively new as humans were not able to generate huge concentrations of carbon dioxide by burning fossil fuels until the emergence of the Industrial revolution.
Part 2:
The phenomenon, which could discharge the compound into the air is the burning of fuels. It is an oxidation reaction in which the carbon present in the hydrocarbons in the fuel is oxidized to carbon dioxide by the presence of oxygen in the air. The carbon dioxide discharged into the atmosphere contributes to the greenhouse effect.
Part 3:
The elements, which produce it are conserved at the time of the carbon cycle by the Law of Conservation of Matter. According to this law, the matter is neither consumed nor produced, it only gets transformed. So, at the time of chemical procedures in the carbon cycle, the atoms of carbon are never destructed, however, they get rearrange and modify into distinct molecules. The mentioned cycle is essential for maintaining life on Earth.

Tara thinks the mean is 6 hours. Who is correct—Meg or Tara? Explain your answer in two or three sentences. Make sure to use facts to support your answer.
Answers
Answer:
The mean would be 6, meaning Tara is correct.
Step-by-step explanation:
The reason to why this is the answer is that I had to add all the “number of hours in a school per day” to get 30. Then, you would have to divide 30 by 5 (because you have five different hours for a school day) to get 6. Your mean would be 6 because mean is adding up the amount of something, then dividing it of how many numbers you added.
Tara think correct mean i.e., 6 . The student spends a mean of 6 hours in school each day.
Tara is correct.
What is mean of the data?Arithmetic mean or mean or average is the number that is obtained by adding the values of all the items of a series and dividing it by the number of observations.

Sample A: 70 100 125 135 70
Sample B: 80 90 120 125 85
For Sample A, the mean will be
[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3035}{500}[/tex]
=6.07
For Sample B, the mean will be
[tex]\frac{\sum fx}{\sum f}[/tex]= [tex]\frac{3045}{500}[/tex]

The average mean will be = [tex]\frac{6.07+6.09}{2}[/tex]

don't let a strange problem description overwhelm you right away.
always try to work with the things you know first. and only when you run into something you really don't know, start thinking.
so, perimeter.
your know, what a perimeter is ? it is the circumference. all the side lengths added together. the answer to "how much distance would you have to go, to walk all the way around it one time".
so, what is the circumference of the square based on what we know ?
well, it has 4 equal sides, right ? otherwise it would not be a square.
so, the perimeter is 4×(x+2) = 4x + 8
that is perfectly fine.
now to the next part we know.
the perimeter of the triangle is the sum of its 3 sides (otherwise it would not be a triangle).
an isoceles triangle is a special triangle that has 2 equal sides.
so, we actually know all 3 sides (at least relatively) :
x+3
x+5
and ... another
x+3 (because of the isoceles property)
so, the perimeter is
x + 3 + x + 3 + x + 5 = 3x + 11
alright.
and now we also know that both perimeters are of equal length.
what did that mean ?
that both expressions deliver the same result.
therefore,
4x + 8 = 3x + 11
aha !
x = 3
bingo !
therefore, the side lengths of the triangle are
x+3 = 3+3 = 6 (both sides in the top)
x+5 = 3+5 = 8
and that's all there is to it.
it is really not necessary to panic don't you think ?

Answers
magnitude size of a number is the number itself, and if it’s negative, it becomes its absolute value (in other words, you remove the subtraction sign).
The magnitude of the negative 5.8 will be 5.8 Then the correct option is D.
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x – h | + k
The magnitude of the number will always be positive.
For example - The value of time, length, mass, temperature etc will always positive.
The magnitude of the negative 5.8 will be
⇒ |-5.8|
When the value in the mode may be negative or may be positive, but when the mode is removed, then the value becomes positive.
⇒ |-5.8|
⇒ 5.8
The magnitude of the negative 5.8 will be 5.8
Then the correct option is D.

Choose the equations that are equivalent.
Check all that apply.
p = two-thirds a + 6
p = negative two-thirds a + 6
a = negative 1 and one-half p + 9
a = 1 and one-half p + 9
a = StartFraction negative 3 p + 18 Over 2 EndFraction
Answers
Answer:
p = -2/3a +6
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Step-by-step explanation:
2a + 3p = 18
Solve for a
2a +3p -3p = 18-3p
2a = 18 -3p
Divide by 2
a = 18/2 - 3p/2
a = 9 - 3/2 p
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Solve for p
2a +3p = 18
3p = 18 -2a
Divide by 3
p = 18/3 - 2/3 a
p = 6 -2/3a
p = -2/3a +6

(b) If gh = 7x and we want a formula for x, we divide both sides by 7 to isolate x:
