Answer:
599 general admission tickets were sold while 277 reserved seats admission tickets were sold
Step-by-step explanation:
Here, we want to know the number of each types of tickets sold.
Let the number of general admission ticket be x while the number of reserved seats ticket be y
Mathematically since the total of both tickets is 876;
then;
x + y = 876 ••••••••••••(i)
The total amount of money generated from general admission is cost of general admission ticket * the number of general admission tickets sold = $2.50 * x = $2.50x
The total amount of money generated from reserved seat admission tickets sales is cost of reserved seat admission ticket * the number of reserved seats admission ticket sold = $5 * y = $5y
Adding both gives $2882.50
Thus;
2.5x + 5y = 2882.5 •••••••••(ii)
Now, from i, let’s say x = 876 -y
Let’s insert this into ii
2.5(876-y) + 5y = 2882.5
2190 -2.5y + 5y = 2882.5
2190 + 2.5y = 2882.5
2.5y = 2882.5 - 2190
2.5y = 692.5
y = 692.5/2.5
y = 277
Recall;
x = 876 -y
Thus;
x = 876 - 277 = 599
Volume of a sphere = (4/3)πr³ π ≈ 3.14, r = 9
Volume, V = (4/3)πr³
V ≈ (4/3)*3.14*9³
V ≈ (4/3)*3.14*9*9*9 Use calculator
V ≈ 3052.08
Option A.
Hope this helps.
Answer:
0.1%
Step-by-step explanation:
138 into a percent=1.38%
156 into a percent=1.56%
175 into a percent=1.75%
1.38-1.56=0.18
1.56-1.75=0.19
0.19-0.18= <u>0.1%</u>
