If you would like to know how much water did Elena drink each practice if she drank the same amount each time, you can calculate this using the following steps:

5 bottles of water ... 7 practices
x bottles of water = ? ... 1 practice

5 * 1 = 7 * x
5 = 7 * x /7
x = 5/7 bottle of water

The correct result would be 5/7 bottle of water.

Answer:

5/7 like you said lol

Answers

Answer:

In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is a taxon in the highest rank of organisms, higher than a kingdom. ... The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Bacteria, and Eukaryota domains.

The picture shows climographs for two different cities... Based ONLY on the TEMPERATURE, which city is probably furthest away from the ocean? *


City 1 is further away from the ocean.
City 2 is further away from the ocean.
Both are the same distance away from the ocean.
There's no real way to tell based on their temperature.

Answers

Answer:

City 1 is further away from the ocean.

Explanation:

I don't have a scientific answer for this. My answer is based solely on the fact that City 1's general temperature is higher than City 2. Being closer to the ocean would cause the temperature to be lower, though I can't remember why. Either way, I hope this helped a little bit at least.

City 1 is further away

Determine whether the objects in the following problems have kinetic energy (KE) or potential energy (PE). Then, use the appropriate formula to calculate the answer.


You serve a volleyball with a mass of 2 kg. The ball leaves your hand with a speed of 30 m/s. The ball has kinetic energy. Calculate it.


A baby carriage is sitting at the top of a hill that is 20 m high. The carriage with the baby in it weighs 10 kg. The carriage has potential energy. Calculate it.


A car is traveling with a velocity of 20 m/s and has a weight (mass) of 1000 kg. The car has kinetic energy. Calculate it.


There is a bell at the top of a tower that is 20 m high. The bell weighs 100 kg. The bell has potential energy. Calculate it.
KE = (0.5)(m)(v)2


Here are the formulas:

m = mass (in kg

v = velocity (in m/s)

PE = mx g x h

m = mass (in kg

On Earth, gravity, g = 9.8 m/s2

h = height (in m)

Answers

Answer: The energy of the ball is 945 Joule

Explanation: A volleyball with a mass of  leaves the hand with a speed of .

To find:

The total energy of the ball.

Consider that the ball exists moving very close to the ground. Hence its potential energy should be zero.

If the ball will possess kinetic energy by the virtue of its motion.

So, net energy or kinetic energy:

Kinetic energy

Therefore, the energy of the ball is 945 Joule.

Why does light we see today tell us something about what happened earlier in the history of the Universe? I will mark brainliest !!

Answers

Because light takes time to get here from there, the farther away 'there' is the further in the past light left there and so we see all objects at some time in the past
