I am greater the 4 tens and less then 5 tens.i have 9 ones what am i ?
Answers
Think of four 10's as
40
And five 10's as
50
It states that you have 9 ones so add to 40
or subtract from 50
49 is more than 40
49>40
and is less than 50
49<50
Good Luck future questions :)

With a ratio,
1 m: 100 cm
x m : 50 cm
1/100 = x/50
x = 50 * 1/100
x = 0.5 m
Whereas, the conversion factor says,
cm/100 = meters
50/100 = 0.5m
The conversion is easier to use since it skips many steps and produces an answer directly.
Answer: Please don't copy and paste my answer. Conversion is simpler if you have the conversion factor.
Step-by-step explanation:
Conversion factor is easier because it uses a known conversion.
for example: 1 foot = 12 inches or 12 inches = 1 foot
or 1 cm= __ mm or 1 m= ___ cm
please don't copy my work or anyone else's. Read what is here and put it in your own words.
Converting measurements using proportions is a little more difficult because you do not know the conversion factor immediately and you have to find it based on information you are given.
For example: lets say I'm playing Minecraft with my 5 friends and I want to make chests for every one in the group, but I haven't played in a long time so i forget the amount of wood needed to make a chest. It's easier for me to make the chests if i already have enough pieces of wood first rather than gathering, then making, then gathering more etc.
I do remember that i will have to go cut down trees to get logs of wood to turn into pieces to make the chest. If i collect 5 logs and go to the crafting table, I am able to turn those logs into 4 pieces per log so I have 5 logs = 20 pieces total.
Then I use all those pieces to craft chests and i discover that I am only able to make 2 chests and I have 4 pieces of wood left over. That means that it takes 8 pieces of wood to make 1 chest. To recap, I now know that 1 log= 4 pieces of wood and it takes 8 pieces of wood to make a chest, so I can say that 2 logs is what i should gather per chest i want to make.
Don't get confused here, I started working this out as a proportion conversion, not conversion factor... I'm just saying that when using a proportion that you still have to find a conversion rate of some kind. So, I guess in a way, we have changed using proportion conversion into a conversion factor because we now know the ratio of 2 logs = 1 chest ( 2 logs of wood= 8 pieces of wood= 1 chest, so 2 logs = 1 chest).
I want to make a chest for every one so now I have to figure out how many logs I need. There area total of 6 of us ( me and 5 friends). 6 people= 6 chests.
so 2 logs= 1 chest and ___ logs = 6 chests
you can also write this as 2/1 = x/6 where x represents the number of logs
2/1= 2 so you can simplify to 2=x/6
multiply each side by 6 to solve for x
12=x
i need to find 12 logs to make a total of 6 chests
So, now that you've read through all of this, the difference is really pretty small between using conversion factor and proportion to convert measurement. Conversion factor is where you already know the conversion and proportion means that you have to find the conversion factor to solve the equation. Don't copy and paste this. Every one is going to obviously say that conversion factor is easier. However, you have to use proportion if you do not already have a set, standard conversion.
Hope that helps!

Answers
We will use the change-of-base formula:
So, if we want to write log6 5 as a logarithm of base 4. in these example a = 6, x = 5, b = 4:
The value of log₆ 5 as a logarithm of base 4 is,
⇒ log₄ 5 / log₄ 6
We have to given that;
Logarithmic function is,
⇒ log₆ 5
Now, WE can write in as a logarithm of base 4 as;
Since, WE know that;
⇒ logₐ b = logₓ b / logₓ a
Hence, By above rule we get;
⇒ log₆ 5
⇒ log₄ 5 / log₄ 6
Thus, The value of log₆ 5 as a logarithm of base 4 is,
⇒ log₄ 5 / log₄ 6

The Following "Verified" Answer is wrong. On Financial Math the answer is...
C.
$1,285
Answer:
Option C. $1,285 more Dylan need to save.
Step-by-step explanation:
Dylan's essential (fixed) expenses = $900 per month
His essential (flexible) expenses = $400 per month
His non-essential expenses = $295 per month
Total expenses per month = 900 + 400 + 295 = $1595.00
He wants an emergency fund of 3 times monthly living expenses
= $1595 × 3 = $4,785.00
currently, in Dylan's emergency fund account = $3,500
Dylan need to save more = 4,785 - 3,500 = $1,285.00
Dylan need to save $1,285 more to have an adequate emergency fund.

The Perimeter: of the rectangular garden that has a width of 4x−6 and a length of 2x+4 is 2(2x - 7) + 2(3*2 + 4x).
What is perimeter?
Perimeter is the sum of length of the sides used to made the given figure.
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
WE need to find the perimeter of a rectangular garden that has a width of 4x−6 and a length of 2x+4.
Area = (2x - 7) * (3*2 + 4x)
Area = (2x - 7) * (6 + 4x)
Area = 8x - 42

Answer:
each side of the square is 25cm
Step-by-step explanation:
this is because of two things:
1. a square has equal sides
2. the perimeter is all the sides added together.
so if you call the length of one side x, you can make this equation:
x + x + x + x = 100
combine like terms
4x = 100
divide both sides by 4
x = 100/4
x = 25
Answer:
25 cm
