To say Hi in Chamoru you say, "Håfa Adai" (Chamorro for "Hello").
Hope this helped!
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
Step-by-step explanation:
LHS = Left Hand Side ; RHS = Right Hand Side
a) RHS = 1/ tan x
= 1/ (Sin x/Cos x)
= Cos x/Sin x
= LHS
b) LHS = Sin^2 x / tan^2 x
= Sin^2 x / (Sin^2 x/Cos^2 x)
=( Sin^2 x * Cos^2 x) / (Sin^2 x)
= Cos^2 x
= 1 - Sin^2 x (Because sin^2 x + cos^2 x = 1)
= RHS
c) RHS = Sin^3 x / tan x + Cos^3 x
= Sin^3 x / (Sinx/Cosx) + Cos^3 x
= (Sin^3 x * Cos x)/Sin x + Cos^3 x
= Sin^2 x * Cos x + Cos^3 x
= Cos x (Sin^2 x + Cos^2 x)
= Cos x *(1) {Because, Sin^2 x + Cos^2 x = 1}
= Cos x
= LHS
Answer:
d, x=5
Step-by-step explanation:
1) get photo math the app. amazing.
2) remove parenthaeses 6x+24=12x-6
move terms 6x-12x=-6-24
collect the like terms,calculate
-6x=-30
divide both by -6
x=5
