The amount Sheila deposits in the Bank of US saving account is $511.
Sabrina has a total of $3,066 she wants to deposit. She has three banks that she wants to deposit her money in.
Let, a represent the amount she would deposit she would invest 7/4 bank.
The amount invested in Catch bank = 6 x a = 6a
The amount invested in Bank of US = 20% x ( 6a + a)
= 0.2 x 7a
= 1.4a
The total amount invested in the three banks can be represented with this equation:
1.4a + a + 6a = 3066
In order to determine the amount she would save in the Bank of US, the amount deposited in 7/4 bank has to be determined first.
8.4a = 3066
a = $365
The amount deposited in the Bank of US = 1.4a
= 1.4 x 365
= $511

For a question like this, all you have to do is remember that a percentage is simply a fraction expressed as a decimal. So, all we have to do is:
, and then multiply our decimal answer by 100 to get the percentage:
= 0.34
0.34 x 100 = 34
Therefore 34% of the students walk to school.
I hope this helped and remember to please try and understand the maths that got the answer, not just writing the answer down :))
Polygons are similar? Well there is no picture provided, so I have no idea what you're talking about. But I think you might be asking if in general all polygons are similar, and if that's the case, they are not. Similar means they are similar in at least one aspect, and all polygons are different from each other, only adding one line for each bigger polygon. So I don't know if this helped you, but I tried anyways.
We can write and solve the differential equation that fits the statement given;
dy/dt = k(50-t)
∫dy = ∫ k(50-t)dt
= ∫ (50k - kt) dt
therefore;
y = 50kt - k/2(t²) + C
Alternatively, can be written as
y = - k/2 (50-t)² + C)
