To avoid a storm, a passenger-jet pilot descended 0.38 mile in 0.4 minute. What was the plane's average change of altitude per minute?

Answers

Answer:

0.55 mile / minute

Step-by-step explanation:

The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

average change of altitude = 0.55 mile / minute

Find the value of b if the graph of the equation y = -5x + b goes through the G(4,3) point.

Answers

Answer:

The Value of b is 23

Step-by-step explanation:

substitute 4 for x, and 3 for y. Then move combine like terms.

3 = -5(4) + b

3 = -20 + b

23 = b

We know that x = 4 and y = 3, so plug those in into the equation
3 = -5(4) + b
3 = -20 + b
add 20 on both sides
23 = b

In complete sentences, explain an advantage and disadvantage for paying by cash.

Answers

Answer:

Step-by-step explanation:The advantag of paying with cash is you don’t have to get a card and swap it sometimes not know the balance on the card rather with money u know exactly how much you have .a problem with cash is that u can drop and not get it back.As if u drop a the card u can lock it and change money to a different account or card.yea so that’s the advantage and disadvantage to paying by cash

hopes this helps

Ok with cash, the advantage is that it’s easier to do and quicker, the disadvantage is that it can be lost very easily and it can be stolen and there would be nothing to do about it. With credit card, if it gets stolen, it can be canceled and you could get a new one. Same if you lose it.

On a round trip over the same roads, Sophia averaged 24 mi/hr going and 30 mi/hr coming back. If the whole trip took 13.5 hours, what is the distance one way? (Hint: Find the time for each part of the round trip)

Answers

Answer:

d = rt. In this problem we are looking for the distance, but we will have to go about it indirectly. If she's traveling the same exact road going and returning, then the distance traveled both ways is exactly the same. Since d = rt, and d is the same, by the substitution property, if and , then , and . So we need to rt for the trip going, rt for the trip returning and set them equal to each other and solve for t. Going is a rate of 24, and the time is t (since we don't know t), and returning is a rate of 30, and the time is 13 1/3-t. (If the whole trip takes 13 1/3 hours, and t is the time going, then the time returning is the difference between the total time and the going time. That concept is one that baffles most algebra students!). So our r1t1 is 24t, and our r2t2 is 30(13 1/3 - t). Set them equal to each other and that will look like this: That fraction of 40/3 is 13 1/3 made into an improper fraction. Distributing that we will have and 54t = 400. That means that t = 7.407. We have time, and that's great, but we need distance! Go back to one of your equations for distance and sub in t and solve for d. d = 24t, and d = 24(7.407), so d = 177.768 miles.

182.25 because if you multiply 13.5 by 24 and add that by 13.5 times 30 and divide that by two that’s the average of the entire way and then you divide by 2 again to get the average distance one way the units would be mi (miles)
