Answer:
Ok time to get math on
So this would be D
A non-filled in dot means < or > (depending where arrow is pointing)
A filled in dot means ≤ or ≥ (depending where arrow is pointing)
if an arrow points right, then it would be greater than, if arrow points left.. Then its less than
So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D
A is greater than which is not the answer
B is only equal to which is way off
C is less than but it is equal which is wrong
D is the only right answer
Hope this helps! :)
Answer:
B
Step-by-step explanation:
For every 1 liter of water, 0.07 kilograms of salt must be added. They are asking for 0.5 liters of water, which is half of 1 liter. So therefore, they need half of 0.07 kilograms of salt, which is 0.035 kilograms

Answer:
17.7 ft
Step-by-step explanation:
A ladder that is 20 feet long leans against the wall of a building such that its base makes a 62 degree angle with the ground. Determine the height, h, that the ladder reaches up the wall. Round your answer to the nearest tenth of a foot.
We solve using the Trigonometric function of sin
sin = Opposite/Hypotenuse
Opposite = Height = ?
Hypotenuse = Length of the ladder = 20 ft
Hence:
sin 62 = h/20 ft
Cross Multiply
h = sin 62 × 20 ft
h = 17.658951857 ft
Approximately = 17.7 ft
