Likurg_2 [28]3 years ago
6 0

Answer:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Two brothers are digging a drainage ditch for a french drain around their home. The ditch is to be 2 feet deep, 1 foot wide, and
alukav5142 [94]

Answer:

The two brothers working together will take 7.7 hours to dig the entire ditch.

Explanation:

Assuming T to be the total amount of time taken by both brothers working together, we can say

  • 1/T ditch/hour to be the rate at which both brothers dig the ditch  together
  • 1/14 ditch/hour to be the rate at which the older brother digs the ditch
  • 1/17 ditch/hour to be the rate at which the younger brother digs the ditch

So the rate at which both brothers dig the ditch can be calculated by the equation,

1/T = 1/14 + 1/17

T = 238/31 = 7.7 (rounded off to the nearest tenth)

1. Describe the differences in the ways the sand castle is changed by an ocean wave and by Dylan stomping on it
Snezhnost [94]

A sand castle that was changed by the ocean waves would be slowly taken away from by the waves and would just become a smooth mound of sand. If Dylan stomped on it then it would still have all of the same sand as before but in a different shape. It would also become a mound of sand but it would have all the same sand as before.


(I don't know if I was supposed to talk about fancy physics stuff so I just gave a basic explanation. I don't know if my answer is really right or not... hope it helped though :))
