A. The ratio in this case is for every 40 minutes : one foot of water is leaked. If we start at 12 pm : 5 foot, next 12:40 pm : 4 foot, then 1 pm would have 3.5 feet. This is because for every 40 minutes is what caused one foot to leak but since we are at 12:40 adding 40 minutes would get us to 1:20 pm, not 1 pm. That means 20 minutes passed, half the time of 40 minutes meaning half the amount of one foot.

B. H(t) would be 40(1).

Given that the solution set to a system of three linear equations is a line, which of the following is true about the system?
Setler79 [48]

The <em><u>correct answer</u></em> is:

d) The system can only be dependent and consistent.

Explanation:

In order for the solution to a system of equations to be a line, this means that the lines must lie on top of one another.  This means they are the same line; the system is consistent since there is at least one solution, and dependent since all of the points in one equation work for the other equations as well.

Approximately how much principal would need to be placed into an account earning 3.575% interest compounded quarterly so that it
Ainat [17]

<u>Answer-</u>

<em>$23377</em><em> must be deposited to get $68000 at the end of 30 years.</em>

<u>Solution-</u>

We know that for compound interest,

A=P(1+\dfrac{r}{n})^{nt}

Where,

A = Future amount = $68,000

P = ??

r = 3.575% annual = 0.03575

n = 4 as interest is compounded quarterly

t = time in year = 30 years

Putting the values,

\Rightarrow 68000=P(1+\dfrac{0.03575}{4})^{4\times 30}

\Rightarrow 68000=P(1.0089375)^{120}

\Rightarrow P=\dfrac{68000}{(1.0089375)^{120}}

\Rightarrow P=23377.45

Therefore, $23377 must be deposited to get $68000 at the end of 30 years.
