The average rate of change between March 15 and June 15 will be given by:
(82.4-66.8)/(6-3)
=15.6/3
=5.2° F per month
Answer: C
X-9=12
x-9+9=12+9
You need to add 9 to each side of the equation.
x=21
The radius is the hypotenuse of the eight triangle. So we can use pythagorean triples to find the side.
It’s handy to remember that 5, 12, 13 is a pythagorean triple.
So, 13 is the radius.
Hope this helped!
<span>the train cannot exceed a length of 1100 feet
Now, train A = 28 cars at 30 feet each
Therefore, Train A's total length = 28*30 = 840 feet < 1100 feet.
</span>Now, train B = 22 cars at 40 feet each
Therefore, Train B's total length = 22*40 = 880 feet < 1100 feet.
Thus, both the <span>trains meet the requirement. </span>
