Answer: sqrt(19)/10
Step-by-step explanation:
sinx=0.9
x=arcsin(0.9)
Insert x for cos(x):
cos(arcsin(0.9)=
Use identify
, so

Sorry if this is confusing.
Your equation would be 2x - 12 + 3x - 15 = 23
Combine like terms and solve for x
Hello! Your answer was 19! There is no possible way for me to show you how to work this out using base ten blocks! Hopefully you can work it out in your head next time! :)
The circumference is 113.04 and multiple that by 7.50 to get 847.8 and i believe that’s the answer.
For 2/5 meter, it takes = 1 min.
For 1 meter, it is = 5/2 min.
Now, for 6 meters, it would be: 5/2 * 6 = 30/2 = 15
In short, Your Answer would be 15 minutes
Hope this helps!
