Density graphs have an area of 1 to represent 100% of the possibilities.

The length is 80

80 * height = 1
Height = 1 / 80
Height = 0.0125 (D)

For a 45-45-90 triangle if the sides rae x then the the hytponuse is x√2
(x is the missing side)

5. 10=x√2
10/√2=x
rationalize denom, times top and bottom by √2
10√2/2=x
5√2=x=XY

6. 12√2=YZ

7.
7√2=XZ

8.
7*2=14=XZ


for 30-60-90
the side oposite the 30 deg is x
side oposite 60 is x√3
side oposite right angle is 2x
hyptonuse is oposite right angle
20=2x
10=x=shorter leg
shorter leg is 10 units
the hyptonuse

Eighteen 2.5 gallon buckets are needed to fill a cistern with water. Find the constant of variation. Please help! Thank you!
Allushta [10]

Given:

Eighteen 2.5 gallon buckets are needed to fill a cistern with water.

To find:

The constant of variation.

Solution:

If y is directly proportional to x, then

y\propto x

y=kx

Where, k is constant of variation.

In the given problem, water in cistern (w) is directly proportional to number of buckets (n).

w\propto n

w=2.5n        (Capacity of each bucket is 2.5 gallons)

Therefore, the constant of variation is 2.5.

"what are the largest values of n for which n! has fewer than 100 decimal digits
ikadub [295]
I can only thin of a hot and miss method to do this . That is using Stirlings approximation for n!-

ln n!  = approx   n ln n  - n

so if we try n = 60    this gives 4.2796 * 10^80 

so we could try higher values:-   

n = 65 gives an 89 digit number

n = 70 gives 98 digit number

n=71 gives me an memory error on my calculator!

Lets try an online calculator

Web2.0 calculator gives  a 101 digit number or n=71

70 is your answer
