The hypotenuse is  \sqrt{2} times as long as either leg

Step-by-step explanation:

a true statement about a 45-45-90 triangle

The common ratio of 45-45-90 degree triangle is

x:x:\sqrt{2}x

Suppose the value of x is 1  then the ratio becomes

1:1:\sqrt{2}

1 is the side length of the triangle and \sqrt{2} is the hypotenuse

The hypotenuse is  \sqrt{2} times as long as either leg

Klio2033 [76]
S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even

Hope it helps!

kvv77 [185]

Answer:

31465 ways

Step-by-step explanation:

Given data

Let us apply the combination formula

nCr = n! / r! * (n - r)!

n= 31

r= 4

substitute

= 31!/4!(31-4)!

= 31!/4!(27)!

= 31*30*29*28*27!/ 4!(27)!

= 31*30*29*28/4!

=31*30*29*28/4*3*2*1

=755160/24

=31465 ways

Hence there are 31465 possible ways to rank it
