The solution would be the coordinates of (3a,a).
The volume of the balloon is 1441.64cm³.
<h3>How to calculate the volume?</h3>
The radius of the balloon is given as 7cm. Also, the equation to calculate the volume is given as c³/6π²
The circumference c will be:
= 2πr = 2 × 22/7 × 7
= 44
The volume will be:
= c³/6π²
= 44³/(6 × 3.14²)
= 85284/(59.1576)
= 1441.64

Отвечать:
440 км
Пошаговое объяснение:
Учитывая, что :
Пройденное расстояние за 27/7 часов = 220 км
Расстояние, которое необходимо преодолеть за 54/7 часов, составит x
Следовательно, мы можем настроить перекрестное умножение:
27/7 = 220
54/7 = х
Крест умножить
27/7 х = 220 * 54/7
27x / 7 = 11880/7
3.8571428x = 1697.1428
х = 1697,1428 / 3,8571428
х = 439,99999
x = 440 км
Таким образом, за 54/7 часов будет преодолено расстояние 440 км.
Answer:
x% of $900=$810
x/100×$900=$810
x=$810/9=90% required percentage is 90%.
His mean score for the first 4 games will be 18 points.
Explanation
In the first 3 games, the mean of the scores is 15 points . Mean is the simple average of some numbers.
So, the total score in first 3 games = 
points
Now, in the 4th game, he scored 27 points. So, the total score in the first 4 games = 
points
Thus, the average of scores in first 4 games = 
points
So, his mean score for the first 4 games will be 18 points.
