It is 12 it’s is 12 it has to be 12
Lets say there were 100 people and 40 ate sandwiches on the first day then 25 percent of 40 is 10, so 10 had sandwiches two days in a row i would say it is true
Answer:
The answer is: y = 7
Step-by-step explanation:
For x = 4, it is a vertical line where everything is x = 4. No matter what y is, x always equals 4.
For the line y = 7, it is a horizontal line, perpendicular to the line x = 4. The line y = 7 passes through the point (-1, 7) and all other similar points where y = 7.
4 boxes with 500 straws each one
4 x 500 = 2000

Answer:
Option B is correct
The average rate of change of d(t) between 2 second and 4 second is; 90 ft/s
and it represents the average speed of the object between 2 seconds and 4 seconds.
Step-by-step explanation:
Average rate of change of function is defined as the ratio of the difference in the function f(x) as it changes from a to b to the difference between a and b. Then, the average rate of change is denoted as A(x).
As per the given statement, the distance d(t) is in feet and t is the time in second.
To find the average rate of change of d(t) between 2 seconds and 4 seconds.
From the table we have;
at t = 2 , d(2) = 60
and
at t =4 , d(4) = 240.
Then, by the definition of average rate of change ;
=
Simplify:
therefore, the average rate of change of d(t) between 2 second and 4 second is; 90 ft/s and it represents the average speed of the object between 2 seconds and 4 seconds.
