let the number be xy then
x + y = 12
y - x = 2 ( because y > x)
adding we get 2y = 14 so y = 7
and x = 12 - 7 = 5
So the number is 57.
Answer:
-1333/1000
Step-by-step explanation:
Evaluate tan(sin^-1(-4/5)).
First we need to evaluate the expression in parenthesis
sin^-1(-4/5)
= sin^-1(-0.8)
= -53.13
SUbstitute the given value into the original expression as shown;
tan(sin^-1(-4/5))
= tan(-53.13)
= -1.333
= -1333/1000
Hence the required answer is -1333/1000
Lin : 1.5 km in 5 minutes = 1.5 / 5 = 0.3 km per minute
Andre : 2 km in 8 minutes = 2 / 8 = 0.25 km per minute
so Lin is biking faster
The answer for the question is 36 , 36
