Answer :

B) 84 m³

Step by step :

$\boxed{ \bold{volume = \frac{1}{3}\pi {r}^{2} h }}$

$volume = \frac{1}{3} \times 3.14 \times 4 \times 4 \times 5 \\ volume = \frac{1}{3} \times 251.2 \\ volume = 83.73 \: {m}^{3} \\ volume = 84 \: {m}^{3}$

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> number of tennis balls

y ----> number of tennis rackets

we know that

To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets

In this problem we have

$\frac{x}{y}=\frac{5}{3}$

$x=\frac{5}{3}y$

That means

The number of tennis balls is three-fifths times the number of tennis rackets

Simplifying it, we get:

6: 15
2: 5

For the boys:

16:40

Simplifying it, we get:

8:20
4:10
2:5

So yes, the ratios are both the same for boys and girls.

Please help me <br>find f(x+h)

Kay [80]

Answer:

f(x) = -2x+5

f(x+h) = -2x -2h +5

g(x) = -4x-2

g(x+h) = -4x -4h -2

h(x) = 4x^2+1

h(x+h) = 4(x+h)^2 +1 = 4x^2 +8xh + 4h^2 +1

Q(x) = -3x^2 +4

Q(x+h) = -3(x+h)^2 +4 = -3x^2 -3h^2 -6xh + 4

Answer: $\triangle XYZ \sim \triangle GFH$ by AA.

Step-by-step explanation:

Finding the third angle in triangle XYZ,

$m\angle YXZ=180^{\circ}-77^{\circ}-48^{\circ}=55^{\circ}$ ,

Thus, $\triangle XYZ \sim \triangle GFH$ by AA.
