Given right triangle ABC. To the nearest degree, find the measure of angle B.

Mathematics
1 answer:
DedPeter [7]3 years ago
4 0

Answer:

Step-by-step explanation:

We have the length of AC which is opposite angle B; we also have the length of the hypotenuse.  We will use trig here to solve for angle B.  The sin ratio is the one that fits.

sin(B) = side opposite / hypotenuse:

sin(B)= \frac{ 4.8}{ 5.1} so

sin(B) = .9411764706

Now we will use the 2nd button on our calculators.  This will give us the missing angle value.  Press 2nd then sin and you will see on your screen:

sin^{-1 (

Enter that decimal after the open parenthesis and hit "enter" to get

B = 70.25 or 70°

in 2012, the general social survey included a question that asked participants how many hours they worked a week. do males work
Agata [3.3K]

Using sampling concepts, it is found that this is an example of independent samples.

  • For dependent samples, there is a paired measurement for one set of items.
  • For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.

In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

A cylindrical milk storage tank needs to be built to hold 84.78 cubic feet of milk. The foundation for the tank has already been
Romashka [77]

Answer:

3 or 2.999 (probably 3)

Step-by-step explanation:

So the volume of a cylinder =  πr^2 * h

h = height

r = radius

now we know the radius. Leaving us with a simple equation which is:

π*9*h = 9π*h = 84.78 =

π*h = 9.42

h = 9.42 / π = 2.99847912785......

but we can round this to 2.999 or just 3. if you use 2.999 the volume is 84.79 which is as close as I'm gonna try to get. And you might ask why we're rounding to 2.999 and not 2.998? This is because that huge number is the minimum. And 2.998 is smaller than that huge number, meaning it would technically be less than 84.78 cubic ft. But this doesn't really matter because the answer your teacher is probably looking for is 3.

Reference my work if you're are confused, however, it's really messy so sorry about that.

How fast is the apple traveling when the kinetic energy is 32 joules?
Daniel [21]

Answer

The apple is traveling at 8 meters per second

Explanation

We have the equation that relates the kinetic energy with the velocty:

K=\frac{v^2}{2}

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

\begin{gathered} 32=\frac{v^2}{2} \\ 32\cdot2=v^2 \\ 64=v^2 \\ v=\sqrt{64}=8 \\  \end{gathered}

Thus, the speed of the apple is 8meter per second
