That would be 42 pages because she has to read 5 pages to get to 200 and then add 37 + 5 which is 42
Answer:
57.2 units^2
Step-by-step explanation:
The coordinates provided form a parallelogram, not a rectangle. See the attached image for a diagram of EFGH. The area of a parallelogram is given by:
Area = (Base) x (Height)
The attachment explains an approach of using right triangles to find the base and height of the parallelogram.
I'm not confident this was the best approach, so I hope someone would comment if a simpler solution is available.
Answer:
Add 2 to each side
x=1/2
Step-by-step explanation:
(3√8x - 2 )= 4
Add 2 to each side
(3√8x - 2 +2= 4+2
3√8x = 6
Divide each side by 3
3/3√8x = 6/3
√8x = 2
Square each side
(√8x)^2 = 2^2
8x = 4
Divide each side by8
8x/8 = 4/8
x = 1/2
Answer:
Horizontal displacement = 100 km
Position with respect to sea level = -0.4km
Step-by-step explanation:
Let the displacement downwards be negative displacement and displacement upwards be positive.
The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.
The upward displacement = 3/5 km
Downward displacement = - 1/10 km and - 9/10 km
Total displacement = 3/5km - 1/10 km - 9/10km = - 2/5 km = - 0.4 km
Horizontal distance from the shore = 100km
