Step-by-step explanation:
Answer:
The general admission ticket number is 160 and the upper box ticket number is 136
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x be general admission tickets number
let y be upper box tickets number
So:
6.5 * x + 10 * y = 2400
x + y = 296 => x = 296 - y
Replacing, we are left with that:
6.5 * (296 - y) + 10 * y = 2400
1924 - 6.5 * y + 10 * y = 2400
10 * y - 6.5 * y = 2400 - 1924
3.5 * y = 476
y = 476 / 3.5
y = 136
Now to calculate x:
x = 296 - 136
x = 160
The general admission ticket number is 160 and the upper box ticket number is 136
Answer: There are 34.35 liters left in the test tube.
Step-by-step explanation:
Since we have given that
Depth of the tube = 9 inches
Circumference of base=4 inches
As we know the formula of circumference ,
Now, we need to find the volume of tube is given by
Since we have also given that,
Of 1 cubic inch of space holds 3 liters of water,
So,
Hence, there are 34.35 liters left in the test tube.
