Answer:
u & v = 8
Step-by-step explanation:
This triangle is a special 45-45-90 triangle!
In a 45-45-90 triangle, to solve for the hypotenuse use the formula
Here we see that 8 is being multiplied by radical 2!
We can prove that 8 is the side length by using the Pythagorean Theorem!
27 is 54% of 50! You can set up fractions (proportions) as 27/50 = blank/100!
Well how do you get to 50 to 100? You multiply by 2! And whatever you do to the bottom you must do to the top! So 27 times 2 is 54!
Answer:
You must add the numbers of the neigbors from the one who counted 52, subtract the number of the one who is opposide and divided by 2.
So i calculate
(44 + 60 - 28) = 38
The knight who counted 52 has 38 peanuts.
Answer:
Step-by-step explanation:
Given
See attachment for soccer field
Required
The possible dimension of the field
From the attachment, we have:
So, we have:
This gives:
Express 36 as 6^2
Express as difference of two squares
Hence, the dimension is:
1/4 * 1/3 * 1/2 * 1/1 = 1/24 chance that all 4 letters are placed in the correct envelopes.
With the first envelope, there are 4 choices of letters, so the probability of picking the correct letter is 1/4.
With the second envelope, there are 3 remaining letters, so the probability of picking the correct letter is 1/3.
The same logic follows the the third and final letter.
