To find an average you add all numbers together then divide by the amount of numbers that you added. So if there are 4 numbers you would divide by 4. By going backwards you can find the answer. Multiply 5 by 4 and you get 20, which is the answer.
Answer:
6n²√3
Step-by-step explanation:
2√3n•√9n³
The above expression can be simplified as follow:
Recall
√9 = 3
2√3n•√9n³ = 2√3n × 3√n³
Recall
m√a × n√b = mn√(a × b)
Thus,
2√3n × 3√n³ = (2×3) √(3n × n³)
2√3n × 3√n³ = 6√3n⁴
Recall:
√aᵇ = (aᵇ)¹/² = aᵇ/²
√n⁴ = n⁴/²
√n⁴ = n²
Thus,
6√3n⁴ = 6n²√3
Therefore,
2√3n•√9n³ = 6n²√3
Answer:
4 1/10 ounces of Liquid plant fertilizer left
Step-by-step explanation:
Total quantity of Liquid plant fertilizer=6 3/5 ounces
Quantity used up on a flower garden=2 1/2 ounces
Quantity of liquid plant fertilizer are left=Total quantity of Liquid plant fertilizer -Quantity used up on a flower garden
6 3/5 ounces -2 1/2 ounces( subtract whole number from whole number and fraction from fraction)
6-2 3/5 - 1/2
4 (6-5) / 10
4 1/10 ounces of Liquid plant fertilizer left
