36...if he now has 18 add the 4 he lost plus the 8 from the box which adds up to the 12 he bought and then add 6 for the other ones he lost
The answer should be x=3. Have a great day!
Answer:
hour
Step-by-step explanation:
Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.
We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.
We will use proportions to solve our given problem as:
We will equate both speeds as:
Cross multiply:
Therefore, it will take hour to complete mile state fair race.
A function for the described sequence is; f(n) = 6• 3^(n-1) and the sixth term is; 1458.
<h3>What is the sixth term of the sequence?</h3>
Since, it follows that the first term of the sequence is; 6 and the common ratio is 3, it follows that the recursive function that represents the sequence is; f(n) = 6• 3^(n-1).
Additionally, by substitution of 6 for n; f(6) = 1,458.

Solution:
1)Distance covered by cyclist=3.75 miles.
Time =0.3 hours.
Speed= Distance ÷Time
Speed =3.75÷0.3=12.5 miles per hour.
2) Speed = 12.5 miles per hour, Distance = 4.5 miles .
Time = Distance ÷Speed.
Time = 4.5÷12.5=0.36 hours.
Time taken to cover 4.5 miles is 0.36 hours.
