Answer:
6.5
Step-by-step explanation:
25 6/12 = 306/12is the total feet of a string
4 3/12 =51/12 feet got lost
To get a remaining part subtract the lost part from the total string
306/12-48/12=255/12
=21 1/4
Therefore the remaining part of a string is 21 1/4 feet
I hope this helps you
a)
sin55=0.81=x/15
x=15/0.81
x=18.5
b)
tan27=0.50=x/20
x=20/0.50
x=40
8 - 3/4 = 4.6 let me know if I made any mistakes =^-^=
3n = 1/81; divide both sides by 3 to isolate n:
3n/3 = 1/81 divided by 3. Remember that when you divide, you use the reciprocal and multiply instead!!
n = 1/81(1/3) = 1/243. Now plug 1/243 back in for n, and 3/243 is equivalent to 1/81
