If it is 5ft a minute then it must be 10ft every two minutes
The volume of water that goes into the hose is the same as the volume of water that comes out the nozzle. This means the velocity is inversely proportional to the area. The area is proportional to the square of the diameter.
Taken together, these facts mean that if the diameter is divided by a factor of 3, the velocity is multiplied by a factor of 3^2 = 9.
Nozzle velocity = 3^2 * entering velocity
.. = 9 * (4 m/s)
Nozzle velocity = 36 m/s . . . . . . . . . corresponding to selection A
Answer:
0?8
Step-by-step explanation:
Cos(A) = Adjacent/hypotenuse
Cos(A) = 36/45
=0.8
Take note that they spent $18 afterwards having $28 on the card so they're spending money off the card so...
x-18=28
would be the equation for this and to solve do the following.
First add 18 to both sides making the equation.
x=46
Yes becuase constant rate will be 24/1
and when you keep subtracting 1 to the x value & and 24 to y value it will end with 0,0 meaning its proportion
