1650 families
Step-by-step explanation:
In a survey of his neighborhood, Timothy found out that 3 families out of 7 have a dog for a pet.
The given ratio = 3:7
When written as a fraction = 3/7
The number of families that would have a pet dog in a town with about 3,850 families is given as:
3/7 × 3,850
= 1650 families
Therefore, 1650 families would have a pet dog in town.

Answer:
84%
Step-by-step explanation:
In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...
19oz + 9oz + 7oz = 35oz
Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.
35oz / 19oz = 1.84
1.84 - 1 = 0.84
0.84 * 100 = 84%
Finally, we can see that the puppy had an 84% increase since the first visit.
