Weight of baby boy , w = 7 lb 8 oz .
Weight of 5 year kid , W = 48 lb .
We know , 16 oz = 1 lb .
So , w = 7 + 0.5 = 7.5 lb .
Now , ratio is :
Therefore , the ratio of the baby's weight to the boys weight as a fraction is
.
Hence , this is the required solution .
If you know the coordinates of two points
of two points, the slope of the line passing through them is given by
So, if we choose in this example
The slope is
Answer:
Step-by-step explanation:
5x^4 + 10x^3 + 15x
5x ( x^3 + 2x^2 + 3)
Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
You want to find the resultant of ...
3 cis 0° +20 cis 20° = (3, 0) +(18.794, 6.840) = (21.794, 6.840)
The magnitude is the root of the sum of the squares of the velocities in the horizontal and vertical directions:
s = √(21.794² +6.840²) ≈ 22.8
The direction is found from the fact that the tangent of the angle is the ratio of vertical to horizontal coordinates:
angle = arctan(6.840/21.794) ≈ 17.4°
The resultant velocity is 22.8∠17.4° meters per second.
The answer is 345 because you have to round
