Consider for a moment building a tree with all possible choices. The first row would contain 8 books (each possible choice for the first book). Then, the second row would contain 7 books for each book in the first row (the choices possible for the second book). Otherwise, it would be 8*7. Following this principal, we continue to multiply down to 1. 8*7*6*5*4*3*2*1. This is also known as 8!, a factorial.
Finally, 8! = 40,320
Answer:
No answer (NO PICTURE)
Step-by-step explanation:
X=3
Because 4*3=12 and 12*2 = 24
Answer:
Step-by-step explanation:
It depends on what you have been told about rounding when a 5 is involved.
If you can round if the answer is 4500, then that would be your answer. If you have some complicated method of dealing with the 5 (involving odd or even numbers) the elephant's minimum weight will be different.
I would go with 4500.
(See the attached diagram.)
We know one leg of a right triangle as well as its hypotenuse. We need to find the other leg using the Pythagorean Theorem.
The Pythagorean Theorem states that 
, where 
and 
are the legs and 
is the hypotenuse.
Insert the known values into the equation. The distance between Susie's house and the school will be represented by .
Convert the decimals to fractions.
To raise a fraction to a power, raise both the numerator and the denominator to that power.
Multiply both sides of the equation by 
.
Subtract 
from both sides.
Subtract.
Divide both sides by .
Take the square root of both sides.
