The is Answer:
82
Explanation:
We observe that difference between first and second terms <span>=12−5=7</span>
Similarly difference between second and third terms <span>=19−12=7</span>
It shows that the given sequence of numbers is an arithmetic progression with common difference equal to 7.
We know that <span>nth</span> term of an AP whose first term is <span>a1</span> and whose common difference is d is given by
<span><span>an</span>=<span>a1</span>+<span>(n–1)</span>d</span>
To find the <span>12th</span> term, insert given values in the general expression
<span><span>a12</span>=5+<span>(12–1)</span>7</span>
<span><span>a12</span>=5+<span>(11)</span>7=5+77=<span>82</span></span>
Answer:
330 hs
Step-by-step explanation:
If Alice sleeps an average of 9 hs and her cat sleeps an average of 20 hours each day we can say that her cat sleeps an average of 11 hours more per day than her.
If the cat sleeps 11 hours more than her per day, for getting the hours he sleeps more by month we just need to multiply the daily value by the number of days in a month. Thus,
30 * (11) = 330
So, her cat sleeps an average of 330 hours more than her in a month, which can be decomposed in 11 hours a day.
I hope it is understandable.
30×30=900
900/112.5=8 cameras to cover
112.5×4=450
900-450=450 ft left uncovered
Answer:
The next time both will leave the bus station at the same time is 7:15 a.m.
Step-by-step explanation:
Since 15 and 75 are multiples to each other.
So, L.C.M. of 15 and 75 is 75.
So, after 75 minutes both buses will leave the station at the same time.
Also since buses begin their routes at 6 a.m.
So, next time they will meet at
6 hours 0 minutes + 75 minutes = 7 hours 15 minutes = 7:15 a.m.
If 1 in is equal to 8 miles
then 1.5×8 = 12 miles
therefore Dale's hpuse and school cannot be on the map because the map is 6 miles? I dont really understand some do the wording of the question
