Hey there! I'm happy to help!

28(5280)=147840 feet per hour.

There are 60 minutes in an hour. To find out how many feet Bolt runs in a second we divide by 60.

147840/60=2464

And we divide by sixty again to get to seconds.

2464/60=41 1/15 feet per second.

Have a wonderful day! :D

Please help I will give 10 pt

The expressions 100×10 and the more complicated

(100 - 4a)(10 + a)

are calculating annual (expected) revenue.  In 100×10 the 100 is the number of decks and the 10 is the price per deck.  In (100 - 4a)(10 + a) the 100-4a is the number of decks and the 10+a is the price per deck.  So a must be the amount the price increases.

Answer: amount of price increase, last choice

Given a cube with a volume of 27cm3, what is the volume of a square pyramid?
VashaNatasha [74]

First from the information we have, we see that the volume of the cube is 27cm3. So what are the dimensions of its length, width and height? This information will help us to determine the dimensions of the square pyramid.


Volume of a cube is found from the formula  V = a3


Where V is volume, and a is the length of one side.


We expand this equation to be:


V= a * a * a


Since all sides of a cube are equal, then this equation will be:


27 = 3 * 3 * 3


Now we know the length width and height of the cube.


Volume of a  square pyramid is given by the formula V =1/3ah


Where V is the volume, a is the area of the base of the pyramid, h is the height of the pyramid.


Since it fits perfectly into the cube, then its dimensions are the same as the cube, so:


Area of the base is Length * Width so:


a = 3 * 3 = 9


and height:


h = 3


Now therefore:


 V =  1/3 * 9 * 3


V = 1/3 * 27


V = 27/3


V = 9 cm3

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:

  see below

Step-by-step explanation:

A left-arrow on a number line represents subtraction of a positive number or addition of a negative number. The two left arrows, one of length 0.2, the other of length 0.1, indicate the numbers -0.2 and -0.1 are being added. The end result is the dot at the end of the combined arrows, at -0.3.

The only expression that is true and corresponds to this description is the one shown below.
