Answer:
c) 
=40Kg
Step-by-step explanation:
To find the answer we have to put all the options in the same unit, so we are going to use Kg.
μ
Replacing the value of μ:
<u><em>Observation:</em></u> 1 g = 0.001 Kg, 1 g=
Kg
This number is very small so it's no suitable for weighing on an ordinary bathroom scale.
- b)
This value is already in kilograms,
But it's small. It's not suitable for weighing on an ordinary bathroom scale.
- c)
Centigrams: cg=
Then,
This value it's suitable for weighing on an bathroom scale.
- d)
Decigrams: dg=
Then,
This value is too big for a bathroom scale. Usually the limit for an ordinary bathroom scale is between 140-150 Kgs.
- e)
Miligrams: mg=
Then,
This could be a right answer too but it all depends on the scale. There are some scales whose minimum weight is 30Kg. So the right answer is c)
Answer:
5
Step-by-step explanation:
you just have to subtract 3 by 8 and then you get 5
<h3>
Answer: 100 meters</h3>
===========================================
Explanation:
If you draw out the diagram, then you'll find that a 45-45-90 triangle forms. The nice thing about this type of triangle is that the two legs are always the same length. The horizontal leg is 100 meters, so the vertical leg must also be 100 meters.
Side note: this type of triangle is an isosceles right triangle.
---------
You could use the tangent rule to get the same thing
tan(angle) = opposite/adjacent
tan(45) = 100/x
1 = 100/x
1*x = 100
x = 100
In this case, the opposite leg is the vertical leg since it is furthest from the angle of elevation.
The number that has the same value would be |-14| because when you do the absolute value of -14, it means that it is 14 spaces away from 0, making it equal to 14.
