Answer:

The answer to your question is x = 16.2

Step-by-step explanation:

Data

angle = 61°

Opposite side = x

Adjacent side = 9

To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

tan Ф = Opposite side / Adjacent side

-Solve for Opposite side (x)

x = Adjacent side x tan Ф

-Substitution

x = 9 tan 61

-Simplification

x = 9 (1.804)

-Result

x = 16.2

Answer: First option.

Step-by-step explanation:

1. To solve this problem you can applly the quadratic formula, which is shown below:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. The quadratic equation is:

$x^{2}-4x-9-29=0\\x^{2}-4x-38=0$

3. Then:

a=1

b=-4

c=-38

4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

$x=\frac{-(-4)+/-\sqrt{(-4)^{2}-4(1)(-38)}}{2(1)}$

x=2±√42

How many cylindrical can of bottles 12 cm high and with 6 cm diameter could be filled from a tank containing 125 liters of deter

Orlov [11]

Answer:

368 cans.

Step-by-step explanation:

Volume of 1 can = π r^2 h.

Here h (height) = 12 and r (radius) = 1/2 * 6 = 3 cm.

So V = π * 3^2 * 12

= 108π cm^3.

The tank hold 125 liters

= 125,000 cm^3, so:

Number of cans that could be filled = 125000/ 108 π

= 368.4.
