Answer:

Step-by-step explanation:
We are given that
Distance traveled by a toy car

Where t>3
Time taken by car =t-3 seconds
We have to find the expression which represents the speed of the toy car.
We know that

Using the formula




Hence, the expression which represents the speed of the toy car

I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.
If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.
After that just check your answer by seeing if the mean of all the numbers is the same.
Answer:
Increased.
Step-by-step explanation:
In March 2007, the unemployment rate was 4.4 percent. In August 2008 was 6.1 percent. We need to remember that the unemployment rate equals the number of unemployed people divided by the people in the labor force.
Now, if we consider that the labor force remained constant during this period of time (according to the problem) then this would mean that the number of unemployed people actually increased during this period of 17 months.
Answer: 25%
Step-by-step explanation: You add all the numbers you are given and you get 40 then take the number from the blue which is 16 then subtract 16 from 40 and you get 24, since 24 is very close to 25 that's how you get 25%
It could also be 40% because you added all the numbers together
Hope this helps :)
