The average increase in the number of smart
phones per year is 45
Step-by-step explanation:
Given that :
Number of students who had phones in 2005 = 120

Answer: The top speed of a zebra is 0.36 feet per second than a wildebeest.
First, we can start by subtracting the top speed of each animal. 64.4 - 64 = 0.4 The zebra is 0.4 km/h faster than the wildebeest.
Now, we just have to move from km/h to feet per second. To start, we need to divide by 3600 because there are 3600 seconds in an hour. Next, multiply by 0.62137 because there are 0.62137 km per mile. Finally, convert the miles to feet by multiply by 5280 (the number of feet per mile).
The result is a speed of about 0.36 feet per second.
Answer:
40
Step-by-step explanation:
To find the area of a parallelogram, you use the following formula:
base x height = area
Using this formula, we plug in the values the question provides, and solve for the area:
base x height = area
8 x 5 = area
40 = area
