Therefore 1364.69 should be rounded up to 1000.
A person has to walk 100 m to go from position X in the north of east direction to the position B and then to the west of Y to r
each finally at position Z. The position Z is situated at the north of X and at a distance of 60 m from X. Find the distance between X and Y.
1 answer:
Answer:
The distance between X and Y is 68m
Step-by-step explanation:
Consider the diagram attached:
A person starts from X, goes to Y, and then finally goes to Z, covering a total of 100m, where Z is located 60m in north of X.
We have to find distance XY.
Let the distance XY be x
Total distance covered by the person = XY + YZ
We know that total distance covered is 100m, so
100m = x + YZ
YZ = (100 - x)m
See the diagram, XZY forms a right angled triangle such that:
Hypotenuse = XY = x
Base = XZ = 60m
Perpendicular = YZ = (100-x)m
Using Pythagoras theorem
Hypotenuse² = Base² + Perpendicular²
x² = (60)² + (100-x)²
Solve the equation for x, we get:
x = 68m

77.76 times
Step-by-step explanation:
The average distance of Neptune from the sun
= 4.503 × 10 ⁹ k m .
and Mercury = 5.791 × 10 ⁷ k m .
Hence neptune is ( 4.503 × 10 ⁹) ÷ (5.791 × 10 ⁷ ) times farther from the sun than mercury
i.e.( ) × 10⁹⁻⁷ times
= 0.7776 × 10 ² times
= 77.76 times.
5.75 quarts of paint required for the project
Explanation:
Usually one quart of paint cover 100 square feet
Since, a gallon covers 250 square feet, it means that
one gallon of paint is equal to quarts of paint.
Number of gallon required to paint 575 square feet,
So, 2.3 gallons is equal to,
