A ball weighs 15lb on earth and 5.7 pounds on mars. What is the constant proportionality between weight of an object on mars and
krok68 [10]
So its asking you to find the gravity on earth relative to the gravity on mars.

Set up an equation to figure out the difference between the two gravities 

15x=5.7
\\x=5.7/15
x=.38

I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.

HELP PLZZ ASAP !! a. The value of x is 6 , what is the value of y?
erastovalidia [21]

Answer:

a). y = 4.5

b) Scale factor = \frac{3}{4}

Step-by-step explanation:

a). Since, polygon Q is the scaled copy of polygon P

    Both the figures will be similar.

    Therefore, their corresponding sides will be proportional.

    \frac{x}{y} =\frac{4}{3}

    If x = 6,

    \frac{6}{y} =\frac{4}{3}

    y = \frac{3\times 6}{4}

    y = 4.5

b). Since, polygon Q is the scaled copy of polygon P,

    Polygon Q will be the image of preimage polygon P.

    Scale factor = \frac{\text{Length of a side of the image}}{\text{Length of a side of the preimage}}

                         = \frac{3}{4}
