Kenny wants to learn how to serve overhand in volleyball. When he practiced yesterday, he made 7 serves over the net for every 2

Yakvenalex [24]

Answer: 28

Step-by-step explanation:

Given

Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is

$\Rightarrow \text{success rate}=\dfrac{7}{2+7}\times 100=\dfrac{700}{9}\%$

for 36 serves, applying the same success rate, it is

$\Rightarrow \text{success rate}=\dfrac{700}{9}\times\dfrac{1}{100}\times 36=28$

Serves that did not make over the net is $36-28=8$

Thus, Kenny will make 28 serves that make over the net

What is the solution of the equation when solved over the complex numbers?<br><br> x^2+27=0

Luba_88 [7]

Answer:

(0,27)

Step-by-step explanation:

x2 + 27 = 0

Solutions based on quadratic formula:

= −0 − √ 02 − 4×1×27 2×1 = 0 − 6 × √ 3 i 2 ≈ −5.196152i

= −0 + √ 02 − 4×1×27 2×1 = 0 + 6 × √ 3 i 2 ≈ 5.196152i

Extrema:

Min = (0, 27)

Find the volume of a right circular cone that has a height of 14.3 ft and a base with a diameter of 17.2 ft. Round your answer t

saveliy_v [14]

Answer:

Volume of the given cone is 1107.6 cubic feet.

Step-by-step explanation:

Formula to get the volume of a right circular cone is,

V = $\frac{1}{3}\pi r^{2}h$

Here r = radius of the circular base

h = height of the cone

Now we put the values in the given formula

Volume = $\frac{1}{3}\pi (8.6)^2(14.3)$ [ radius = $\frac{17.2}{2}=8.6$ ]

= $\frac{1057.628\pi }{3}$

= 1107.55

≈ 1107.6 cubic feet

Therefore, volume of the given cone is 1107.6 cubic feet.
