Answer:

180 minutes

Step-by-step explanation:

The problem above needs "conversion of units" from hour to minutes. Remember that: 1 hour = 60 minutes

So, if the meeting started at 9:45 a.m. and ended at 12:45 p.m., then the meeting's duration is 3 hours.

The next step is to convert 3 hours to minutes since the problem is asking for the answer in minutes.

So, 3 hours x $\frac{60 minutes}{1 hour}$ = 180 minutes (this is the answer)

The temperature outside was 3°F at midnight. During the next hour the temperature fell 7°. What was the temperature at 1 A . M

Dahasolnce [82]

If the temperature was 3 degrees Fahrenheit at Midnight, and it dropped 7 degrees during the next hour, then the temperature at 1 A.M. would be -4 degrees Fahrenheit. This is true because 3 - 7 = -4.

So, the answer to this question is that the temperature was -4 degrees Fahrenheit at 1 A.M.

Let $d$ be the common difference between terms in the sequence $\{a_n\}_{n\ge1}$ . Then

$a_{19}=-58$
$a_{20}=a_{19}+d$
$a_{21}=a_{19}+2d$
$\implies-164=-58+2d\implies d=-53$

The first term in the sequence, $a_1$ , satisfies

$a_2=a_1+d$
$a_3=a_1+2d$
$a_4=a_1+3d$
...
$a_{19}=a_1+18d$
$\implies-58=a_1+18(-53)\implies a_1=896$

So the explicit formula for the $n$ -th term in the sequence is

$a_n=a_1+(n-1)d\implies a_n=896-53(n-1)$
