Answer:
No solution, this is not an arithmetic sequence
Step-by-step explanation:
An arithmetic sequence is the same number being added over and over. This is not the case.
Answer:
1.2144xx
Step-by-step explanation:
The multiplier of value for the first year was (1 +38%) = 1.38.
The multiplier of value for the second year was (1 -12%) = 0.88.
Then the multiplier of value for the two years was ...
1.38×0.88 = 1.2144
The value of the stock after 2 years was ...
1.2144xx

Question:
Lisa walks at an average speed of 6 km/h for 15 hours.
Dan completes the same distance in an hour. Calculate Dan's average speed.
Answer:
Step-by-step explanation:
Given
Lisa:
First, we calculate the distance covered by Lisa:
So, Dan distance can be represented as:
--- Dan completes the same distance as Lisa
-- Time to complete the distance
Dan's average speed is:
<em>Hence, Dan's average speed is 90km/hr</em>
Answer:
134 kilometers or 83 miles.
Explanation:
First make all the units equivalent, so
60 km/h = 60 km/h or 37.28 m/h
45 m/h = 72.42 km/h or 45 m/h
50 km/h = 50 km/h or 31.07
So in one hour the car has gone 60 km or 37.28 m because they travel at 60km/h, which means they get that far in that amount of time.
In half an hour they get half of 45 miles, because 45 m/h means they get 45 miles in 60 minutes, so in 30 minutes, or half and hour, they are getting half of 45 = 22.5 miles or 36.21 kilometers.
In 45 minutes they are getting 75% of 50 km because 45 minutes is 75% of an hour. So 75% of 50 is 37.5 km or 23.3 miles.
Add this all together and get:
Kilometers:
60 + 36.21 + 37.5 = 133.71 km
Miles:
37.28 + 22.5 + 23.3 = 83.08 m
133.71 km = 83.08 So it checks out.
This is approximately 134 km or 83 miles.
