Answer:
7 stations
19 stations
199 stations
Step-by-step explanation:
We can model the stage number as 
, and the number of modules as 
. We can write this as a linear equation, where the initial number of modules is 1, and the number of modules increases by 2 every station. This is 
, but since if you plug in 1 into the equation, you get 3, which is the station number for the next number, you have to edit that into x - 1:
Expanding, we have 2x - 2 + 1, which is 2x - 1:
Now, plugging 4 into the equation, we have 7.
Plugging 10 into the equation, we have 19.
Plugging 100 into the equation, we have 199.
Answer:
0.06
Step-by-step explanation:
0.42 ounces is enough for 14 plants. After watering 12 plants, there will be enough plant food left over for 2 plants. Write a proportion:
0.42 / 14 = x / 2
Cross multiply:
14x = 0.84
Solve:
x = 0.06
Answer:
The surface = pi*10cm2
Step-by-step explanation:
The area of any rectangle is Base * Height,
We know that the square originally has 10cm High, when is rolled to form a cylinder, it's new shape has a bottom side that is equals to a circle.
The length of a circle is 2*pi*Radio= pi*Diameter.
Since the square has the same length in each side, we know that pi*Diameter= 10cm*pi
The surface (area) of the cylinder is= Base * Height= 10cm*10cm*pi
Answer:
16
Step-by-step explanation:
8^(4/3)
replace 8 with 2^3
2^3 ^ (4/3)
2 ^ (3*4/3)
2^ 4
16
