Answer:
4
Step-by-step explanation:
We have an arithmetic sequence with
<span>a0 = 1st 3-digit number divisible by 13 </span>
<span>a0 = 104 </span>
<span>d = 13 (why?) </span>
<span>last term is largest divisible by 13 = 988 </span>
<span>how many terms? (988-104)/13 + 1 = 69 </span>
<span>S = 69/2(104+988) = 37674</span>

Answer:The dragon fly can fly 35/12 miles
Step-by-step explanation:
Speed =distance / time
If the distance A dragonfly flies 7/8 of a mile
And
Time =3/10 of an hour.
Speed =7/ 8 ÷3/10 =7/ 8 x 10/3 =70/24 reducing to lowest term becomes 35/12 miles / hour
Now when the dragon fly flies in 1 hour, its distance covered becomes
Speed =distance / time
35/12 miles / hour=distance / 1
distance =35/12 miles
