If we assume the pool to be a semi sphere, then the volume would be
<span>
V pool = 1/2 * [4/3*pi*r**(3)]
</span>where r is the radius = 50m
V pool = 1/2 * [4/3*3.14*50**(3)]
<span>
V pool = 261799.3878 m</span>³
If we round up >>> V water in the pool = 261800 m³<span>

Answer:
a = 20 . . . . liters
Step-by-step explanation:
To solve this, multiply the equation by 30+a:
a = 0.4(30 +a)
a = 12 + 0.4a . . . . . eliminate parentheses
0.6a = 12 . . . . . . . . subtract 0.4a
a = 12/0.6 = 20 . . . divide by the coefficient of a
20 L of alfalfa must be added
_____
<em>Check</em>
20/(30+20) = 20/50 = 40/100 = 0.4 . . . . . . answer checks OK
Answer:
x = -1.25
Step-by-step explanation:
2.25x + 5 = 13.5x + 14
subtract five from both sides
2.25x = 13.5x + 9
subtract 13.5x from both sides
-11.25x = 9
swap the negative
11.25x = -9
divide 11.25 from both sides
x = -1.25
Answer:
f(x) is linear
g(x) is exponential
Step-by-step explanation:
A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.
First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:
All of these points are the same distance apart on the y, so f(x) must be a linear function.
Now look at g(x). These are also all equally distant at only 1 unit apart.
These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.
Step-by-step explanation:
first do the parenthesis
4x-3(3x+3x)>18
4x-3(6x)>18
4x-18x>18
-14x>18
