So. hmmm we know the arc entry has a vertical clearance of 66 feet, and is 46feet wide
notice the picture below.. if we move the arc to the origin, we end up with a parabola like so, from -23, 0 to 23, 0
now
The answer is A I don’t this before
Answer:
d+d=90
Step-by-step explanation:
A complementary angle is equal to 90 degrees. If it is made up of two triangles (d and d) when you add them, they're total will be 90.
Answer:
A
Step-by-step explanation:
The displaced volume of the water, because of the submersion of the object, is equal to the volume of the object.
So to find the volume of the object we calculate the difference in volume of water:
33.1-25.1 = 8 ml
Since 1 mL of water has the volume of 1cm^3, then the volume of the object is 8 cm^3.
The density of the object is found by the formula:
density= mass/volume= (3 g) / (8 cm^3) = 3/8 (g/cm^3)= 0.375 g/cm^3
Answer: 0.375 g/cm^3
