Answer:
microalgae required less space.
Step-by-step explanation:
Amount of oil to be produced = 1,000 gallons
Now,
We know
10,000 gallons of oil is extracted from the miroalgae per acre per year
and,
From soyabeans the oil extracted = 50 gallons per acre per year
therefore,
To produce 1,000 gallons number of acres required by microalgae
= [ Amount of oil to be produced ] ÷ [ oil extracted per acre from microalgae]
= 1,000 ÷ 10,000
= 0.1 acres
similarly
To produce 1,000 gallons number of acres required by soyabeans
= [ Amount of oil to be produced ] ÷ [ oil extracted per acre from soyabeans]
= 1,000 ÷ 50
= 20 acres
hence,
microalgae required less space.
Hello,
To exist x≠0
if x>0 then
x+2/x>=3==>x²+2>=3x
==>x²-3x+2>=0
==>(x-2)(x-1)>=0 positive out of the roots
==> (x<=1 or x>=2) and x>0
==>(0<x<=1) or (x>=2)
else
x<0
x+2/x>=3==>x²+2<=3x
==>x²-3x+2<=0 negative betheen the roots
==>(1<=x<=2) and x<0 : no solution
end if
Answer:
5,184•b•t^6/5
Step-by-step explanation:
Here, we want to multiply the expressions
According to indices law, if we have same bases, we add up the exponents
Thus, we have that;
8 *8b^(2/3+5/3) * 9 * 9 * t^(3/5+3/5)
= 64 * b * 81 * t^6/5
= 5,184bt^6/5
Answer:
312 mi/hr
Step-by-step explanation:
Distance = 2184 miles
Time taken = 7 hours
Average speed = Distance / time taken
Average speed = 2184 miles / 7 hours
Average speed = 312 miles per hour
Hence, the average speed Traveled by the plane traveling from Knoxville to Los Angeles is 312 miles per hour
