Here is the equation:

Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:

r is equal to 4 → r = 4
Answer:
I would need more information but I believe its A
Step-by-step explanation:
Answer:
405
Step-by-step explanation:
We can use a ratio to solve
3 infected x infected
------------------ = ----------------
50 sampled 6750 population
Using cross products
3*6750 = 50x
Divide each side by 50
3*6750/50 = x
405
Step-by-step explanation:
Hypotenuse : Opposite the right angle.
Opposite : Opposite the angle.
Adjacent : the last side left.
Your formulas.
Soh Cah Toa (Sin Cos Tan)
You'll be using Cos (Cah) because hypotenuse and adjacent are the only sides with something in it.
You rearranged formula :
Side length × Cos (Angle) = your answer to x
Answer:
5000x^2 is the 4th term
Step-by-step explanation:
ok, 1 bionimial theorem coming right up
for a binomial expansion of (a+b)^n
the kth term is
means
n is 5
4th term
4-1=3
and a=2x
b=5
so
(10)(4x^2)(125)
5000x^2 is the 4th term
