Answer:
1.) 90 ways
2.) 15,600 ways
3.) 24 ways
Step-by-step explanation:
1.)  Let's say   we are given 2 digits not equal to each other...The number of different orderings would be  2*1 = 2, or  if we wanted the number of ways to order 2 digits chosen :   10*9 = 90 ways
2.)   The number of ways to arrange 3 letters from 26 letters is:
26 Permutes 3  =    26! / (26 -3)!  =  26*25*24 = 15,600 ways to choose 3 letters in a certain order
3.) 4 different chores.  The number of ways to do them =  4*3*2 *1 = 24 ways
 
        
             
        
        
        
Remember, you can do anything to an equation as long as you do it to both sides
for inequalities, if you multiply or divide both sides by a negative number, you flip the direction of the inequality sign
-5.3≥6.7+4.3+q
add like terms
-5.3≥11+q
minus 11 both sides
-16.3≥q
q≤-16.3

Answer:
y= -1*x +12
Step-by-step explanation:
x=4 is a function that always has the value 4 for the x-axis, no matter y variable, this a vertical function.
Perpendicular Lines are those with the following condition:
y=a*x+b (1)
y=c*x+d (2)
Where a and c are the respective slope
If These two lines are perpendicular, then
a=- 1/c
Using those principles we have that the slope for our needed line has to be -1, since the slope for the first line is 1 (the coefficient of x is 1, in the line x=4)
Lets use the given point (5,7) in the equation (2)
7=-1 * 5 + d
resulting d=12
so, our equation for the line is y= -1*x +12
 
        
             
        
        
        
Answer:
<h2>5/36 days</h2>
Step-by-step explanation:
Given that Karen would exhaust 6 bags of lemons in a day at his stand
the question is how long will 5/6 bags last.
we can see that 5/6 is not even up to a bag of lemon, seeing that even 6 would last for a day
so if 
6bags last for 1 day
5/6 bags will last x day
cross multiply 
6x= 5/6
divide both sides by 6 we have
x= 5/6/6
x= 5/6*1/6
x= 5/36 days
5/36 days
