10 and the math be hide it is 600/60=10
85/15 is 5 2/3
so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.
12*5 2/3=68.
you could also find it using the 1% method:
1% of 15 is .15.
.15*85=68.
Hope this helps!
In a triangle, the three interior angles always add to 180°
m∠1 = x+20
m∠2 = 2x+10
m∠3 = 4x-60
x+ 20 + 2x + 10 + 4x - 60 = 180
7x - 30 = 180
7x = 180 + 30
7x = 210
x = 210/7
x = 30
m∠1 = x+20 = 30 + 20 = 50°
m∠2 = 2x+10 = 2*30 + 10 = 70°
m∠3 = 4x-60 = 4 * 30 - 60 = 60°
Answer:
The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.
Step-by-step explanation:
P(x,n) is a polynomial of nth degree if it is of the form,
P(x,n) = 
where n is a finite positive integer and n ∈ N
and '
's are fixed but otherwise arbitrary constants ∀ i = 0(1)n .
Now, the given expression is,
which doesn't fit in the above form. Hence, it is not a polynomial.
