Answer:
H. 40%
Step-by-step explanation:
18/30 = 60%
So 60% of kids have last names with more than 8 letters.
That means 40% of kids have last names with fewer than 8 letters.
(Because the percentages have to add up to 100)
Hope this helps! :)
Answer: 
Step-by-step explanation:
If we have y=7x-1/2, the inverse is where we solve for x instead of y.
We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.
Therefore, .

Answer:
sin(x) = cos(90°-x)
Step-by-step explanation:
Looking at the graphs of sin(x) and cos(x), you can see that the peaks of the graph are separated by a value of pi/2. If you convert that value into degrees, then the two graphs are separated by 90°. Another way of thinking is from the unit circle. sin(x) = 1 at 90°, and cos(x)=1 at 0°. The difference is still 90°
