Answer:
6 hours
Step-by-step explanation:
12km/ 3= 4 km per hour so
24/4=
6 hours
The answer is hollow sphere
23.8÷28=0.85
0.85 Liters
every liter is 1000 mililiters.
0.85 Liters is 850 mililiters.
Well you pay 50$ for the first one, for the second one your paying 12.50 less and for the third one your paying 25 less, if you add them together you get 112.5, it originally would have costed 150, so you would subtract 150 - 112.5, which equals 37.5 so she saved 37.5 dollars on the rings(Here is a quick simple short way to do it.. she payed 12.50 less and 25 less that added together is 37.5)
The solution would be like this for this specific problem:
sin(θ°) = √(2)/2
θ° = 360°n + sin⁻¹(√(2)/2) and θ° = 360°n + 180° −
sin⁻¹(√(2)/2)
θ° = 360°n + 45° and θ° = 360°n + 135° where n∈ℤ
360°*0 + 45° = 45°
360°*0 + 135° = 135°
360°*1 + 45° = 405°
<span>sin(225°) = -√(2)/2
</span>225 has an angle where sin theta= -(sqrt2)/2 therefore, the value of theta
cannot be 225 degrees.
