Can someone break this down for me?!

Mathematics
1 answer:
Anna [14]3 years ago
5 0

Answer:

The answers are in the question.

Step-by-step explanation:

The wording can be off-putting but the answers are mostly there for you. It says that when the wind was at the tail of the plane, the travel was hastened to 5 hours instead of six. Is the rate of speed with the wind in favor of the plane is r+21, then it stands to reason that traveling AGAINST the wind will cause the rate to drop to r-21. Taking the average of the two travel times (5 and 6 hours each), we get 5.5 hours. Since speed is distance divided by time, the speed of the plane in still air will be <em>d</em> / 5.5

Be sure to label the speed as mph.

I need help with this problem quick.
KatRina [158]

The absolute value - or distance from zero, is fairly simple to find. Make your final answer positive to find it.


|\frac{10-7}{4}| = |\frac{3}{4}| = |.75| = .75

|\frac{-15+8}{6}| = |-\frac{7}{6}| = |-1.2| = 1.2

What is the probability of not drawing a card 6 or greater from a regular deck of cards?
Mamont248 [21]
Ok so there are 52 cards in a deck if you take all the cards that have the number 6 which is only 4 cards so 52-4 = 48 cards without any 6 so the ratio is 48/52 
chances.

If you're trying to take any card that is greater than 6 its a little more complex there is T,2,3,4,5,6,7,8,9,10,B,Q,K so you have to tack away 6,7,8,9,10,B,Q,K from 4 rows so 8 x 4 =32 cards 52-32= 20 so the probability of not having any cards greater than 6 is 20/52
