Answer:
volume of the tank be when the sensor turns on = 92.316 ft³
Step-by-step explanation:
Volume of a cylinder = πr²h
Pi = π = 3.14
Radius = r = 7 ft
Height = h = 3 ft
Volume of a cylinder = πr²h
= 3.14 × 7² × 3
= 3.14 × 49 × 3
= 461.58 ft³
The tank comes equipped with a sensor to alert the farmer to fill it up when the water falls to 20% capacity.
volume of the tank be when the sensor turns on = 20% of Volume of a cylinder
= 0.20 * 461.58 ft³
= 92.316 ft³
volume of the tank be when the sensor turns on = 92.316 ft³
Answer:
66
Step-by-step explanation:
50% = 1/2
33 x 2 = 66
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
Answer:
-0.5 would be the most likely outcome

Answer:
length of each edge = (x + 3)
Step-by-step explanation:
The surface area of each face of the cube = (
+ 6x + 9) 
. But the surface of a cube has the shape of a square. So that,
Area of a square = length x length
= 
By factorizing the area,
+ 6x + 9 = + 3x + 3x + 9
= ( + 3x) (3x + 9)
= x(x +3) + 3(x + 3)
= (x + 3)(x + 3)
= 
+ 6x + 9 =
Thus,
=
find the square root of both sides
l = (x + 3)
length of each edge = (x + 3)
