Answer:
About 76%.
Step-by-step explanation:
To find the average of numbers, you add all of the numbers together and divide the total by the number of numbers. In this case, your numbers would be 95 twice, 87 five times, 73 three times, 63 four times, and 40 once. The total number of numbers is 15, and the total of all of the exam scores if you add them up is 1136. Finally, you would divide 1136 by 15, which would be 75.7333333, which would be an average of about 76%.
Answer:
In 2011, 44,500 units are produced
Step-by-step explanation:
Let
t ----> the number of years after 2005
f(t) ----> the number of units produced by a company
we have
f(6)=44,500
so
For t=6, f(t)=44,500
That means
The number of units produced by a company is equal to 44,500 units six years after 2005
so
six years after 2005 is the year 2011
therefore
In 2011, 44,500 units are produced
Answer:
It'll take 7 hours for the car B to cath up to A
Step-by-step explanation:
In order to solve this problem we can write the equation from the distance of each car. Assuming that t = 0 happens when the second car leaves Toronto. When the second car leaves Toronto, the first one is on the road for two hours already, thefeore it travelled a total of:
distance = speed*time = 70*2 = 140
We have:
Car A:
x(t) = 70*t + 140
Car B:
x(t) = 90*t
We now need to find the value of "t" that makes x(t) the same for both cars:
90*t = 70*t + 140
20*t = 140
t = 140 / 20 = 7 h
