We know, surface area of cube = 6a²
So, side length of 1st cube = a² = 81/6
a = 3.67
Side length of 2nd cube = a² = 144/6
a = 4.90
Now, volume of cube = a³
Volume of 1st cube = 3.67³ = 49.43
Volume of 2nd cube = 4.90³ = 117.64
So, Ratio = 49.43 / 117.64 = 1/2.38
In short, Your Answer would be: 1: 2.38

Answer:
The number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E is 10,080 ways
Step-by-step explanation:
We need to find the number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E.
There are 9 letters in the word WONDERFUL
There is a condition that letter R is always next to E.
So, We have two letters fixed WONDFUL (ER)
We will apply Permutations to find ways of arrangements.
The 7 letters (WONDFUL) can be arranged in ways : ⁷P₇ = 7! = 5040 ways
The 2 letters (ER) can be arranged in ways: ²P₂ =2! = 2 ways
The number of ways 'WONDERFUL' can be arranged is: (5040*2) = 10,080 ways
So, the number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E is 10,080 ways
Set it up:
13 -27
---- x ----
2 8
then make the bottom numbers the same:
52 -27
---- x ----
8 8
After this you just multiply:
-1404 -351
--------- = ---------
64 16
thats the final answer
Answer:
X = 10 Y = 14
Step-by-step explanation:
Okay, so. If you divide the Y and X for example 2.8 divided by 2 is 1.4 5.6 divided by 4 is 1.4. So like it says it is proportional. So, when you get down to the eight. You can see they are adding the X by 2 so the X is 2. The Y would be 2.8. So, you would add 2.8 into 11.2. That would be 14.
