Answer: a. 5/12 b. 10 hours
Step-by-step explanation:
5/8 x 2/3 = 10/24 = 5/12
she spends 5/12 of the day awake at home
if a day has 24 hours then 5/12 of that is 5/12 x 24 = 10
so she spends 10 hours awake at home
Answer: 7 1/30
Step-by-step explanation: convert to improper fractions then find lowest common denominator between them then add and simplify back to mixed fraction :)
Cos θ=1/3
cos θ=sen (90-θ)
therfore:
sen (90-θ)=1/3
To chek
θ=arc cos 1/3=70.53º
sin (90-θ)=sin (90º-70.53º)=sin 19.47≈0.3333≈1/3
Answer:
Step-by-step explanation:
The question makes sense for all values of x, but I imagine that is not exactly what you mean.
I think you mean for what values of x does the question produce a real square root?
The answer is as long as x + 2 does not drop below 0, the results will be real.
Put mathematically x ≥ -2 gives a real result. For now just don't try and take the square root of a minus number.
