Answer:
The answer to your question is: 1123 persons
Step-by-step explanation:
long = 36 ft
wide = 78 ft
Area = long x wide
Area = 36 x 78 substitution
= 2808 ft²
a standing person occupies 2.5 ft²
# of standing person in the tennis court = 2808 / 2.5
= 1123.2
The number of hydrogen and oxygen atoms that should be in the products according to the law of conservation of matter, is given as follows:
4 hydrogen atoms and 2 oxygen atoms.
<h3>What is stated by the law of conservation of matter?</h3>
The law of conservation of matter states that the amount of matter in the solution remains constant, even when the substance has a change in the format.
The amounts on the equation are given as follows:
- 2 oxygen atoms in the reactants.
The law of conservation of matter states that the amounts remain constant, hence the amounts of the solution are given as follows:
- 2 oxygen atoms in the reactants.

Answer:
101/140
Step-by-step explanation:
<u>Solving in steps:</u>
- -6/15 * 4/7 - (-7)/20 * 4/7 + 3/4 =
- - 2/5 * 4/7 + 7/20 * 4/7 + 3/4 =
- - 8/35 + 7/35 + 3/4 =
- -1/35 + 3*35/4*35 =
- -4/140 + 105/140 =
- 101/140
