Answer: 43.58 min
Explanation:
Knowing the volume of a rectangular object is length x width x height, we have two volumes:
And we know it takes a time of 4 minutes to fill 
.
If we want to know how long will it take the same hose to fill another tank with volume 
, we can use the <u>Rule of three</u>, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known:
---- 
---- 
Finally:
It makes it easier to dig a hole because it helps pick up dirt
Answer:
why do the layers of sedimentary rocks parallel to earth's surface?
Why are sedimentary rocks found on or close to Earth's surface?
Explanation: Erosion breaks existing rocks and turns them into sediments. ... When subjected to heat and pressure deeper in the earth sedimentary rocks are changed into igneous and metamorphic rocks. Because erosion only happens on the earth's surface sedimentary rocks are only formed on the earth's surface.
Explanation:
Why do sedimentary rocks have layers and how these layers are formed?
The different groups of sediments could have been deposited through wind, water, ice, and/or gravity at different intervals of time and compacted on top of each other, until they create a sedimentary rock that has several different types of sediments (possibly from different rock types) in the form of layers.
The speed of a sound wave does not depend on the frequency of the wave, but only on the properties of the medium.
Since we are in the same concert all, the medium of propagation is still the same (the air), so it has not changed; therefore, the speed of the sound wave has not changed, and it is still 344 m/s.
So, the correct answer is "344 m/s".
