Answer:
Up to 60% of the human adult body is water.
Step-by-step explanation:
First you must state that the relationship is proportional. It is because it goes into the origin.
y = 2.5x
k = 2.5 And 2.5 is the constant of proportionality.
Answer:
The equation that describes the path of the water balloon is:

Step-by-step explanation:
The motion of the water balloon is represented by quadratic functions. Tommy launches a water balloon from
and hits Arnold at
. Given the property of symmetry of quadratic function, water ballon reaches its maximum at
, which corresponds to the vertex of the standard equation of the parabola, whose form is:
(Eq. 1)
Where:
- Vertex parameter, measured in
.
,
- Horizontal and vertical components of the vertex, measured in feet.
,
- Horizontal and vertical location of the ball, measured in feet.
If we know that
,
,
and
, the vertex parameter is:



The equation that describes the path of the water balloon is:

0.92
Step-by-step explanation:
There are 4 cards in a deck of 52 cards that has a face value of 3. That means that the other 48 cards don't have a face value of 3. Therefore, the probability of picking a card of this deck that doesn't have a face value of 3 is
