.2 or 2/10 If you do 3/4 of the 4/5, you get .6 or 6/10. With that, you can do 1/3 of .6 or 6/10 which equals .2 or 2/10
Answer:
Step-by-step explanation:
We know that,
where,
r = radius,
θ = central angle in radian.
Given,
diameter = 6 m, so radius = 3 m.
Putting the values,
Answer:

Step-by-step explanation:
Bus A: $40 + ($4 * 30) = $160
Bus B: $100 + ($2 * 30) = $160
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.
