Set up a proportion:
4.1/22 = 12.3/x
Cross multiply:
4.1 * x = 22 * 12.3
4.1x = 270.6
Divide 4.1 to both sides:
x = 66
Answer: 600
Step-by-step explanation: Cancel the common factor of 10 to get 600.
<span>Given that 35% of the tracks are curved, this means that 100% - 35% = 65% of the tracks are straight.
Therefore, the fraction of the tracks that are straight is given by

Answer:
A:
B:
c: 2x
Step-by-step explanation:
To find the derivative of x raised to the nth power we use the following template
Something else to keep in mind is that
So knowing this we can rewrite a as follows
so we can use the template above and get
So that simplifies to
B: Same kind of deal here
C: this one is by far the easiest because the derivative of a constant is 0 so we can just apply the same template from before and get
2x
