Answer:
a
Step-by-step explanation:
put it into desmos and you get that
We have that
if the <span>machine can bottle 30 fluid ounces of shampoo in -----------> 12 seconds
X f</span>luid ounces of shampoo in-----------------------------------------------> 1 second
X=30/12=2.5 (<span>I apply a rule of three)
</span>
the answer is 2.5 fluid ounces of shampoo
<u>ANSWER </u>
<u>EXPLANATION</u>
We the have the equations,
Multiplying through by negative one gives,
Also
and
Dividing through by 2 gives
Making z the subject gives,
Now we substitute equation (3) into equation (1) and (2)
Equation (3) in to equation (1) gives,
This implies that;
We now put equation (3) in (2) to get,
This implies that
But
So,
Dividing through by negative 9 gives
and
Therefore
You would do pi x r squared. r=12, and 12 squared is 144. pi (3.14) times 144 equals 452.16!
