Answer:

Step-by-step explanation:

use law of sines

Sin(A)/a =Sin(B)/b

Sin(Ф)/ 2 $\pi$ = Sin(110) /5 $\pi$

Sin(Ф) = 2 $\pi$ * Sin(110) /5 $\pi$ (cancel the pi)

Sin(Ф) = 2/5 * Sin(110)

Sin(Ф) =2/5 * 0.93969262

Sin(Ф) = 0.37587704

Ф = arcSin( 0.37587704)

Ф = 22.0785°

Ф = 22.08° ( rounded to nearest 100th)

suppose that during one period of extreme cold the average daily temp decreased 1 1/2 Fahrenheit each day how many days did it t

Nina [5.8K]

Answer:

The temperature decreased by 9 °F in <u>6 days.</u>

Step-by-step explanation:

Let the number of days it takes for the temperature to decrease by 9 °F be $x$ .

Given:

Average daily temperature decreases by $1\frac{1}{2}$ °F.

Decrease of temperature in 1 day = $1\frac{1}{2}$ = 1.5 °F.

∴ Decrease in temperature in x days is $1.5x$ .

Now, as per question, decrease in temperature in 'x' days is 9 °F.

Therefore, $1.5x=9$

$x=\frac{9}{1.5}$

$x=6$

Therefore, the temperature decreased by 9 °F in 6 days.

You are designing a container in the shape of a cylinder. The radius is 6 inches. You want the container to hold at least 324π c

natta225 [31]

By definition, the volume of a cylinder is given by:

$V =\pi r^2h$

Where,

r: cylinder radius

h: cylinder height

From here, we clear the height.

We have then:

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

Then, replacing values we have:

$h = \frac{324\pi }{\pi 6^2 }$

$h = 9 inches$

Answer:

The least possible height of the container is 9 inches.
