Alice practices basketball by taking 10 shots a time from different distances from the hoop. She determined that the
distance from the hoop and the number of successful shots can
be modeled by the equation y = -x where x is the difference in
feet from the hoop and y is the number of successful shots. By
how many shots does her performance decrease when she
increases her distance from the hoop by 3 feet?
answer choices
4 shots
1 shot
2shots
5shots

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

answer and explanation;

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
