y varies inversely as x

y = K / x , where K is any constant

y = 15 when x = 5

15 ( 5 ) = K = 75

y = 75 / x

When x = 25 ,

y = 75 / 25

y = 3

How much does a cat way on the moon

Gwar [14]

Answer:

Since weight is directly dependent on the acceleration of gravity, things on the Moon will weigh only 16.6% (≈ 1/6) of their weight on Earth.

Step-by-step explanation:

Being that the moon has a gravitational force of 1.622m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon.

The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.

cos A = $\frac{12}{20} = \frac{3*4}{5*4} = \frac{3}{5}$
ANSWER: $cosA= \frac{3}{5}$

As a salesperson at Max’s Mattresses, Richard earns $250 plus $15 for each mattress he sells. Which equation can Richard use to

DedPeter [7]

Answer:

e = 250 + 15m

Step-by-step explanation:

The earnings or "e" are determined by the solution of the $250 he's earned from the start and the $15 he earns are dependent on the amount of mattresses he's sold so "m" has to be multiplied by the 15.
