<u>Answer</u>
18.5 m²
<u>Explanation</u>
The figure is a sector of angle 85° and of radius 5 m.
The area = θ/360 × π × r²
= 85/360 × 3.14 × 5²
= 18.5347
The answer to one decimal place is 18.5 m²
7 + 18 = 25
25 ÷ 7 = 3.5714285714285714285
so 3.5714285714285714285 is the answer
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:
The numbers are 44 and 46
Step-by-step explanation:
Let
x, x+2 ----> the two consecutive positive even integers
we know that
Solve the quadratic equation using a graphing calculator
The solution is x=44
see the attached figure
therefore
The numbers are 44 and 46
