Answer:
162m²
Step-by-step explanation:
distance from corner to center = 1/2 of the diagonal
all sides are equal, and this has 4 sides, so it is a square
9m = 1/2 of diagonal
multiply both sides by 2 to isolate the diagonal
18m = diagonal
area of square = length²
length * √2 = diagonal
given the diagonal, we can find the length and then the area
length * √2 = diagonal
divide both sides by √2 to find the length
18m/√2 = length ≈12.7
square the length to find the area
area = 162 m²
Answer:
use the long addition method

Answer:
The correct answer is 20 kg.
Given, Weight (w) = 910 N , g = 10 ms-2
So, mass (m) = (w / g) = 91kg
Important Points
Mass is a measure of the amount of matter in an object.
Mass is always constant.Weight is the force of gravity on an object.
Weight depends on the gravitational force of attraction.
Weight (w) = Mass (m) * Gravitational acceleration (g).
The weight of a body is greater in the pole of the earth than in the equator, because of acceleration of gravity at the poles is 980.665 cm/sec2 while at the equator it is 3.39 cm/sec2 less due to the centrifugal force.
Answer:
She originally had 7 necklaces.
Step-by-step explanation:
She now has 18 necklaces. She bought four more. That would be 18 - 4 = 14. She gave half of them to her sisters. 14 divided 2 is 7.
