this formula is used to determine gpm (gallons per minute) of flow with a known hose diameter (d) and nozzle pressure (np). The constant (29.7) is consistent when figuring flow with in gallons with a know pressure expressed in psi (pounds per square inch).
Scenario example: a firefighter is using a handline to fight fire with an 1 3/4 inch line with a nozzle pressure of 100 psi. How much water is the firefighter flowing when fighting fire?
Answer:
sin p -21/29
cos q 21/29 so here you go °~sohcahtoa~°
Step-by-step explanation:
sin means you find the soh part so you look for the oppisite over hyponuse
and for cos your looking for cah part so you find the adjsent over hypotnuse so the ansers is 21/29
Answer:
The answer is 5X+16
Step-by-step explanation:
The formula for perimeter of a triangle is a+b+c.
meaning we are adding up everything.
That is
(x)+(x+11)+(3x+5).
collect like terms.
and u end up getting
5x+16
Answer:
a ≈ 5.3
Step-by-step explanation:
Using Pythagoras' theorem
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 6² = 8², that is
a² + 36 = 64 ( subtract 36 from both sides )
a² = 28 ( take the square root of both sides )
a = 
≈ 5.3 ( to the nearest tenth )
The volume is 12 cm just multiple each 4
