Answer:
$180.
Step-by-step explanation:
Given: Pay for 7.5 hours is $45.
To find: Pay for working 30 hours.
Solution: It is given that pay for 7.5 hours is $45. In order to find the pay for hours we first need to find the pay for 1 hour, then we are able to find the pay for 30 hours as well.
Now, pay for 7.5 hours
pay for 1 hour
So, for 1 hour the pay is $6.
Now, to find the pay for 30 hours, we need to multiply the pay per hour by 30.
Therefore, pay for 30 hours
Hence, pay for working 30 hours is $180.

To solve this we are going to use the formula for the volume of a sphere: 
where
is the radius of the sphere
Remember that the radius of a sphere is half its diameter; since the first radius of our sphere is 24 cm,
. Lets replace that in our formula:
Now, the second diameter of our sphere is 36, so its radius will be:
. Lets replace that value in our formula one more time:
To find the volume of the additional helium, we are going to subtract the volumes:
Volume of helium=
We can conclude that the volume of additional helium in the balloon is approximately <span>17,194 cm³.</span>
