I guess you mean 4/5 and 3/5
this is a right angled triangle with side 3-4-5 so 5 is the hypotenuse
sin x = opp / hyp = 4/5 so the opposite side is 4
cos x = adj/hyp = 3/5 so the adjacent side = 3
so tan x = opp/adj = 4/3
Answer:
8%
Step-by-step explanation:
let,
this year population of students (pt)= 195
last year population of students (p)= 210
time(t)= 1 year
Population Change( R)= ?
we have,
pt= p( 1 - R/100)^t
195 = 210 ( 1 - R/100)^1
0.92= 1 - R/100
0.92-1= R/100
- 0.08 = - R/100
R= 0.08×100
R= 8%
Answer:
2.5
Step-by-step explanation:\
We can solve it like this
4 + x = 6.5
6.5 - 4 = x
6.5 - 4 = 2.5
SO
4 + 2.5 = 6.5
Answer:
2/3
Step-by-step explanation:
just divide the numbers by 6 the first time and get 4/6 and then divide one more time and get 2/3
