Lets see
a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other
no cannot
The change in value over 4 years is
$22,000 - 30,000 = -$8,000
so the average change in value per year is
-8000/4 = -2000
Answer: Rational
Step-by-step explanation: 12 is a rational number because it can be expressed as the quotient of two integers: 12÷ 1
I think it's the third one b/c
the associative property states that it doesn't matter how you group the
numbers in parenthesis in addition.
So to set up this equation, you have to do
Time1*Workers1=Time2*Workers2
In this case, Time1=24 days, Workers1=15 electricians, and Workers2=18 electricians, and we have to solve for Time2
Thus we get 15*24=18*Time2
Time2=15*24/18=20 days
