Answer:

4 bags

Step-by-step explanation:

the formula for area is A=3.14 x r^2, r is radius, found by 380 divided by 2, giving you A=3.14 x 190^2, giving you 113,000. divide by 500, giving you 226, then divide by 70, giving you 3 and a decimal, round up, and you get 4.

What is the measure of z? 3 27 y x z
Sholpan [36]

Answer: 3\sqrt{10}

Step-by-step explanation:

By the geometric mean theorem,

\frac{y}{3}=\frac{27}{y}\\y^{2}=81\\y=9

So, by the Pythagorean theorem,

3^{2}+9^{2}=z^{2}\\90=z^{2}\\z=\boxed{3\sqrt{10}}

Find the coordinates of the turning point of y = x^2 + 8x + 17
Amiraneli [1.4K]

Answer:

(-4 , 1)

Step-by-step explanation:

We know that the turning point of any parabola is in its vertex. The x of the vertex can be calculated with the formula:

x = -b/2a

In our case b = 8, a = 1, so:

x = - 8/2 = -4

We plug this value into our original equation and find the y of the vertex:

(-4)^2 + 8(-4) + 17 = 16 - 32 + 17 = 1

Vertex = (-4 ; 1)

Water is being sprayed from a nozzle at the end of a garden hose of diameter 2.25 cm. If the nozzle has an opening of diameter 1
Gwar [14]

Answer:

4.67 m/s

Step-by-step explanation:

The equation of continuity for an incompressible fluid is A1v1 = A2v2 where A represents area and v is velocity of the fluid.

If we let the values with subscript 1 be those inside the hose and 2 be those at the nozzle then the question can be solved this way

A_{1} v_{1} = A_{2} v_{2} \\\\(\pi *0.01125^{2} )*v_{1} = (\pi *0.00065^{2} )*14\\\\v_{1}  = 4.67 m/s
