Answer:

The measure of the outside angle is the sum of the two inside angles:

68+52=120

Or you could do it the long way and find the third angle inside the triangle then do 180 minus that but this is easier.

What is the value of the y-intercept of the line 7x-4y=20?<br> 7/4<br> 5<br> -5
USPshnik [31]

Answer:

-5

Step-by-step explanation:

Once you get y alone the equation will look like this y=-7/4x-5.

The slope intercept form dictates that y=mx+b, with b being the y-intercept, so -5 is b, therefore the y intercept.

For every 9 minutes of music Shawn listens to, Greg listens to 4 minutes of music. How many times more minutes of music does Sha
Vaselesa [24]
Hello.

The mathematical concept of this problem is basic once you get down to it. The question asks, "How many times more minutes does Shawn listen to than Greg?"

Remember the "How many" rules:
· "How many more" suggests subtraction
· "How many times" suggests division

Let's also take a look at our opening sentence: "For every 9 minutes of music Shawn listens to, Greg listens to 4 minutes of music." This means we can set it up as a fraction, as we have the phrase "For every" in our sentence. So, let's do that.

\frac{9}{4} is our fraction;
To simplify, we need to divide our numerator (the number on the top) by our denominator (the number on the bottom).
9 / 4 = 2.5

This is our rate, or how many times more music Shawn listens to than Greg.

Your answer is: "Shawn listens to 2.5 times more music than Greg."

I hope this helps!

Answer:

Step-by-step explanation:

The decibel level of the sound of a monster truck is

Further explanation:

Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.

In the question it is given that the intensity of the sound of a monster truck is watts per square inch.

The formula which is used to calculate the decibel level of a sound is as follows:

Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .

The value of the threshold intensity of hearing at is watts per square meter.

This implies that the valiue of is watts per square meter.

The intensity of the sound of a monster is given in unit of per square inch.

The relation between per square inch and per square meter is as follows:

So, the intensity of a monster truck is converted into per square meter as follows:

This implies that the value of is watts per square meter.

Now, substitute the value of and in the equation .

The approximated value of the above equation is as follows:

From the above calculation it is concluded that the decibel level of the sound of a monster truck is .

Please help! I am completely lost on these things
Flauer [41]
Its pythagoras I think ^^; so 9^2 + 4.5^2 = 101.25 then square root it to get 10.0623059   just in future do a^2 + b^2 = c^2 (adjacent squared plus opposite squared gives you the longest side which is the hypotenuse squared) I hope that helps! ^^;
