80
adding up the numbers 30,20,5,25
maybe im wrong but i hope it helps...
Answer:
I think its A tell me if i'm right :)
Step-by-step explanation: and B i'm not 100% sure
F(x+2)= -x^2 -4. Use basic transformations
You are correct. The area of a square with side lengths of 1/3 yard is 1/9 yd^2.
To get this answer, you muse use the formula for finding the area of a square, which is s^2, where s represents the value of a side length.
The value of the side length in this case is 1/3 yard, so we should substitute that value in for s.
When we do this, we get the following:
A = (1/3 yd)^2 = 1/9 yard^2
Therefore, your answer is 1/9 yd^2.
Hope this helps!
To find the rate (or speed) of an object you use the equation
Rate = Distance x Time or
d = rt So, just fill in the equation with the first set of numbers.
64 = r(1.7) Then divide.
r ≈ 37.65
Then, find the second speed.
d = rt
80 = r(1.9) And divide.
r ≈ 42. 11
Since you need to find the average speed just find the average of the two speeds. So
(42.11 + 37.65) / 2
79.76 / 2
39.88
So the average speed of the train was about 39.9 miles per hour.
