Turn the percentage into a decimal by sliding the decimal twice from the right to the left and multiply it to the number
add/subtract it depending on if it's increasing or decreasing
Answer:
i think photomath can help with the question I'ma check
Lets solve for t in the height equation:
h = 7 cos (pi/3 t)
cos (pi/3 t) = h/7
pi/3 t = cos^-1 (h/7)
t = (3/pi) <span>cos^-1 (h/7)
then we substitute:
</span>t = (3/pi) <span>cos^-1 (1/7)
</span>t = 78.1 s
t = (3/pi) <span>cos^-1 (3/7)
</span>t= 61.71
t = (3/pi) <span>cos^-1 (5/7)
</span>t = 42.41
those are the times in seconds respectively.
Answer:
I believe 90
Step-by-step explanation:
because if you take away 25 (40 pounds) from 100, you divide 100 by 2 to see how many pounds that are 2 $ fit in 100
100/2=50 (pounds)
so 50pounds + the 40pounds (which was the 25$ i took off to make it easier) =90 pounds
hope I helped and feel free to ask questions :)
