Answer:
1. 10 weeks
Step-by-step explanation:
Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.
... $6 × w = $60
Divide by $6 to get ...
... w = $60/$6 = 10
Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

<em>Comment on the problem statement</em>
The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)
Answer:
Therefore,the level of paint is rising when the bucket starts to overflow at a rate
cm per minute.
Step-by-step explanation:
Given that, at a rate 4 cm³ per minute,a cylinder bucket is being filled with paint
It means the change of volume of paint in the cylinder is 4 cm³ per minutes.
i.e
cm³ per minutes.
The radius of the cylinder is 20 cm which is constant with respect to time.
But the level of paint is rising with respect to time.
Let the level of paint be h at a time t.
The volume of the paint at a time t is


Differentiating with respect to t

Now putting the value of 



To find the rate of the level of paint is rising when the bucket starts to overflow i.e at the instant h= 70 cm.

Therefore, the level of paint is rising when the bucket starts to overflow at a rate
cm per minute.
