Answer:
12.5 kilograms
Step-by-step explanation:
Given:
Half of the granola served with breakfast.
Let the amount of Granola present initially = 
kg
Half of it (
) served with breakfast, so remaining granola :
After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.
First of all, let us convert it to kilogram because the answer is required in Kilograms.
We know that:
1000 gms = 1 kilograms
1 gms = 0.001 kilograms
6250 gms = 6250 
0.001 = 6.250 kilograms
Now, as per given question statement:
So, the answer is:
Girl scout camp started with 12.5 Kilograms of granola.
The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>
Answer: The speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
Step-by-step explanation:
Since we have given that
Speed at which woman walks due west = 3 mi/hr
Speed at which ship moving due north = 22 mi/hr
Now it forms "Pythagorus theorem":
So, it becomes,
And the direction of the woman relative to the surface of the water is given by
Hence, the speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
All you have to do is to reverse the order of the x and y components of (7,2):
(2,7).
