Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
The volume of the solid generated when the right triangle below is rotated about side is 564.2.
<h3>How to calculate the volume?</h3>
The volume will be calculated by using the formula:
= 1/3πr²h
where, r = 7
h = 11
Therefore, the volume will be:
= 1/3πr²h
= 1/3 × 3.14 × 7² × 11
= 564.2

So a dime is .10 or 10 cents
a quarter is .25 or 25 cents
12(.10)=$1.2
4(.25)=1
the equations would be
.25(x)
.10(x)
and if you need them combined it would be
.25(x) + .10(x)
