Answer:
T = 40 (minutes?)
Step-by-step explanation:
Given the equation G = 50 + 20T, where G = the total amount of gas and T = the amount of Time, we know that there is already 50 gallons of gas in the tank and that the rate at which it is pumped is 20 gallons per minute (I am assuming, though it is not stated in the problem). Given that the tank holds 850 gallons, we can plug in the values into the equation and solve for the missing variable, T:
850 = 50 + 2T
Subtract 50 from both sides: 850 - 50 = 50 + 2T - 50 or 800 = 2T
Divide 2 from both sides: 800/2 = 2T/2
Solve for T: 40 = T
Answer:
A ≈ 494.80 
V = 827.02 
Step-by-step explanation:
height ( <em>h </em>) = 13 mm
radius ( <em>r </em>) = 
= 4.5 mm
Surface area = 
= 2π(4.5)(13) + 2π(4.5)
≈ 494.80
Volume = 
<em> </em>= 
= 827.02
To combine like terms and single out one term to take it easier to solve, the 6x was moved to the other side to combine like terms.
Subtracting 6x from 10x which is 4x
If the length of the entire screwdriver is 19cm, and the handle is 5cm, subtract the length of the handle from the total length to find the length of the top of the screwdriver.
19 - 5 = 14
The top of the screwdriver is 14cm long.
