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.
Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.
Answer:
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Step-by-step explanation:
In a triangle, the sum of all inside angles must be 180 degrees.
In this question:
The inside angles are: x, x + 50 and 180 - 3x.
Then
x + x + 50 + 180 - 3x = 180
2x - 3x = -50
x = 50
So
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Answer:
the degree of x can be added to 120 to get 180. they form a straight line which is 180°. subtract 120 from 180 to get you answer.
180-120=60 so x=60
