If last week Salazar played 13 more tennis games than Perry and they played a combined total of 53 games, then Salazar played a total of 33 games.
Let the total number of games played by Perry be x.
It is given that, Salazar played 13 more tennis games than Perry.
⇒ Total games played by Salazar = x + 13
Also, Salazar and Perry played a combined of 53 games.
Hence, total number of tennis games played by Salazar and Perry = 53
⇒ Games played by Salazar + Games played by Perry = 53
⇒ x + (x + 13) = 53
2x + 13 = 53
2x = 53 - 13
2x = 40
x = 40 / 2
x = 20
Therefore, total number of games played by Salazar = x+13
= 20 + 13
= 33
Thus, Salazar played total 33 games.

Answer:
Its volume for a sphere where radius is 3cm
The real volume is 113.04 cubic meter
I believe you would calculate this like so;
We want 18% less than 100% of that amount therefore the single multiplier we would use is as follows:
(100% - 18%) = 82%
Which alternatively = 0.82
Does that make sense? If not I can explain it a bit more. Please let me know.
The ratio of the triangle is 55/1.1, which is 50/1.
This means that the building is 50/1 = x/5
x = 250
The office building is 250 m tall.
