Answer:
I answered it using pictures because I dont know how else to put the answers down.
Michael is x. Michelle is y.
x+y=27
x-5=y
Substitute y
x+(x-5)= 27
2x-5=27
2x=32
x=16
Plug in x value
(16)+y=27
y=11
Final answer: Michael-16, Michelle-11
Answer:
The amount that plant earns per man hour after (t) years it open is $80
.
Step-by-step explanation:
Given as :
The earning of manufacturing plant when it opened = $ 80 per man hour
The rate of plant earning per man hour = 5 %
Let The earning of plant after t years = A( t )
So,
The earning of plant after t years = initial earning × 
Or, A(t) = $ 80 × 
or, A(t) = $ 80 × 
Hence The amount that plant earns per man hour after (t) years it open is $80

Answer:
sin θ = 
Step-by-step explanation:
Given that,
cos θ = 
From the trigonometric functions,
cos θ = 
⇒ adjacent =
, and the hypotenuse = 3
Let the opposite side be represented by x, applying the Pythagoras theorem we have;
=
+ 
=
+ 
9 = 3 + 
= 9 - 3
= 6
x = 
Thus, opposite side = 
So that,
sin θ = 
= 
Therefore,
sin θ =
