Answer: 1679</h3>
=========================================================
Explanation:
The notation 
means "47 degrees, 4 minutes". The "minutes" isn't referring to a time value, but instead they are arc minutes. If we divide one degree into 60 equal pieces, then we form 60 arc minute slices. So in a sense, we are using a round analogue clock to help connect the two ideas.
We can convert to purely degrees through using this formula here
So,
and similarly,
Now subtract the two results we got
47.06667-22.76667 = 24.3
The angular distance between the two cities is 24.3 degrees. By "angular distance" I basically mean how far you need to rotate your viewing angle when looking from city A to city B. Imagine that you're able to be situated at the center of the earth.
The circumference of the earth is
C = 2*pi*r
C = 2*pi*3960
C = 24,881.4138164311
which is approximate and the units are in miles. We multiply by the fraction 24.3/360 to find the arc distance along the curve that corresponds to the angle 24.3 degrees. This is because we don't want the whole circumference, but just a small fraction of it.
So (24.3/360)*24,881.4138164311 = 1,679.4954326091
This rounds to 1679
The distance between the two cities is about 1679 miles.
For example,
write 3 5/4 in simplest form.
3*4+5=12+5=17
17/4 is in simplest form.
Answer:
Step-by-step explanation:
In 30 minutes she can walk 2 miles. We'll put that as a ratio. 30:2. Now to figure out how much she walks in 45 minutes, we set variable to x and make it stand for how much she walks. We have 30:2 = 45:x We cross multiply to get 30x=90, x=3. Tara can walk 3 miles in 45 minutes.

Answer:
6
Step-by-step explanation:
There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.
So without all the insignificant 0's, the number would look like this:
13.0049
