Answer:
The correct option is the last
Step-by-step explanation:
To answer this question we must remember the exponents properties
It is known that when we have division of exponents of equal base, then we place the same base and subtract the exponents.
In this problem we do the opposite, that is, we have an expression in the form of exponents and we write it as the division of exponents of the same base.
![p_2 = 100000(0.4) ^ {d-4}](https://tex.z-dn.net/?f=p_2%20%3D%20100000%280.4%29%20%5E%20%7Bd-4%7D)
Then p2 can be written as:
![p_2 = \frac{100000 (0.4) ^ d}{(0.4) ^ 4}\\\\p_2 = \frac{100000 (0.4) ^ d}{0.0256}\\\\p_2 = 3906250 (0.4) ^ d\\](https://tex.z-dn.net/?f=p_2%20%3D%20%5Cfrac%7B100000%20%280.4%29%20%5E%20d%7D%7B%280.4%29%20%5E%204%7D%5C%5C%5C%5Cp_2%20%3D%20%5Cfrac%7B100000%20%280.4%29%20%5E%20d%7D%7B0.0256%7D%5C%5C%5C%5Cp_2%20%3D%203906250%20%280.4%29%20%5E%20d%5C%5C)
Therefore the correct option is the last

Answer:
x = 60
Step-by-step explanation:
(x+22) + (x+6) + (x-28) = 180
x + 22 + x + 6 + x - 28 = 180
x + x + x + 22 + 6 - 28 = 180
3x = 180
x = 180/3
x = 60
Hi!
Let's find the volume of the cylinder first.
The equation to find the volume of a cylinder is
(r = radius, h = height)
v = πr²h
Fill in the values
v = π · 100² · 250
Solve
v = π · 10000 · 250
v = π · 2500000
v = 7853981.63
Now since the cylinder is half-full, divide by 2.
7853981.63/2 = 3926990.81
To find how many liters are in the container, divide
1 liter = 1000
3926990.81/1000 = 3926.99081
Round to the nearest liter
3927
There are 3927 liters in the cylindrical tank
Hope this helps! :)
