Answer:
Step-by-step explanation:
h^2=x^2+y^2, since this is a square x=y=s so
220^2=2s^2
2s^2=48400
s^2=24200
s=24200^(1/2)m (exact)
s=155.56m (rounded to nearest hundredth of a meter)
One hectare is equal to 10000m^2
A=24200m^2(h/10000m^2)
A=2.42 hectares
Answer:
The correct options are:
- The closure property of multiplication states that the product of two rational expressions is a rational expression.
- The commutative property only holds true for the multiplication of rational expressions.
- The properties of rational expression multiplication and division are parallel to the properties of rational number multiplication and division.
Step-by-step explanation:
We know that if a and b are two rational expression than :
Closure property of multiplication states that:
a.b is also an rational expression.
Commutative property under multiplication is given by:
a.b=b.a
The commutative property holds only under multiplication and not division since, if a=0 then,
a/b=0
but b/a is not defined.
Also, the property of rational expression are parallel to the properties of rational number.
Steps:
"Of" means "x" (times)
For 20% pretend there is an imaginary decimal at the end and move that decimal all the way to the front.
Now what is .20 of (times) $60 = 12
I think that's what you wanted. The discount price
