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

Answer:
Yes, i believe that the generalization about the measure of a point angle of a star polygon is true.
First we find sum of interior angle of an n-sided star polygon.
number of triangle in a polygon = n - 2
sum of interior angle of a triangle = 180°
sum of interior angle of an n-sided star polygon = ( n - 2 ) × 180°
To find measure of a point angle, we use:
× 180°
To find a point angle we eliminate density by multiplying d by 2 in the formula for finding number of triangle, divide the whole by total number of sides and then multiply by the sum of interior angle of triangle(180°).
Since all the angle of a regular star polygon are equal, we can calculate each pointy interior angle of a regular star polygon using the formula given below:
× 180°
Answer:
Part A: 272 teenagers surveyed like hard rock.
Part B: 200 is the total number of teenagers that Damian surveyed.
Part C: Polly surveyed 850 teenagers to find out their favorite type of music. She found that 132% of the teenagers surveyed like hard rock.
Step-by-step explanation:
Part A: % = 1/100, 32% = 32/100, so 32% of 850 is
32/100 x 850 = 272.
Part B: if Total is T, then 75% of T is = 150, i.e,
75/100 x T = 150, making T subject of relation, then T, Total = 200.
