Which one is correct ?
Firdavs [7]

Answer:

13.3

Step-by-step explanation:

If AM is 6 and MB is 4, the total length of AB is 10. The ratio of the sides ΔABC and ΔAMN is going to be 5:3 since that 10 divided by 6 can be simplified to 5 divided by 3. If AN is 8 and the ratio of AN to AC is 3:5, the value of AC could be rounded to 13.3.

Hope this helps and stay safe !

Compute the sums below. (Assume that the terms in the first sum are consecutive terms of an arithmetic sequence.)
riadik2000 [5.3K]

Answer:

=18975

Step-by-step explanation:

This is an arithmetic sequence

an = a1 +d(n-1)

a1 =9

d = 12-9 = 3

an = 9 +3 (n-1)

The sum of an arithmetic sequence is given by

Sn = n/2 (a1+an)

So we need to determine what number in the sequence 336 is

an = 9 +3 (n-1)

336 = 9 +3(n-1)

Subtract 9 from each side

336-9 =9+-9 + 3(n-1)

327 = 3(n-1)

Divide each side by 3

327/3 =3/3(n-1)

109 = n-1

Add 1 to each side

109+1= n-1+1

110 = n

336 is the 110  term

The sum from 9 to 336

Sn = n/2 (a1+an)

S 110 = 110/2 (9+336)

          = 55 (345)

          =18975
