Answer:

-54\ \frac{ft}{sec}

Step-by-step explanation:

we know that

To find out the mean change of altitude, divide the total change by the amount of time it takes

so

-\frac{378}{7}=-54\ \frac{ft}{sec} ---> is negative because the airplane is descending

garri49 [273]

Answer:

i find the design and functionality very coonfusing and poorly done, voice mail messages will not play, endlessly loading, even tried reinstalling, doesn't help, update: seems to be that you have to force quit the app and then start it again in order to listen to any voice messages, that is a major flaw and why has this been going on for so many months that I've lost count yet no one at the mighty Microsoft corporation seems to be competent enough to fix this?

Cindy has two bags
Bumek [7]

Answer:

Step-by-step explanation:

There are a total of 10 balls in the first bag, so P(1 red) = 3/10 and P(1 green) = 7/10.There are a total of 9 balls in the second bag, so P(2 red) = 4/9 and P(2 green) = 5/9.P(1 red & 2 red) = 3/10 × 4/9 = 12/90 = 2/15P(1 red & 2 green) = 3/10 × 5/9 = 15/90 = 1/6P(1 green & 2 red) = 7/10 × 4/9 = 28/90 = 14/45P(1 green & 2 green) = 7/10 × 5/9 = 35/90 = 7/18

I hope you understand it!

in sunlight, a vertical stick has a height of 3ft and casts a shadow 2ft long. at the same time, that a nearby tree casts a shad
Gnoma [55]
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
