A car travels at a constant speed of 65 miles per hour. The distance the car travels in Miles d, which is a function of time, t.
PolarNik [594]

Answer:

  t(d) = d/65

Step-by-step explanation:

To solve for t, divide by its coefficient:

  d = 65t

  d/65 = 65t/65 . . divide* by 65

  d/65 = t . . . . . . . simplify

Then you can write it in function form if you like:

  t(d) = d/65

_____

* Of course, the rules of equality say you must divide <em>both sides</em> of the equation by the same number.

A volcano in the approximate shape of a cone has a diameter of 16 km and a height of 1.95 km. Which estimate best approximates t
masha68 [24]
To find the approximate volume of the volcano, you will use the formula for finding the volume of a cone.

V = 1/3 x pi x r^2 x h
     1/3 x 3.14 x 8^2 x 1.95
V = 130.624

The approximate volume of the volcano is 131 cubic kilometers.

Need the answer on this ​
denpristay [2]
None of the answers are correct because it’s definitely not “Given” because x=20 is like an answer. It’s also not “Distributive Property”, “subtraction Property”, and or “Additional Property” b/c there’s nothing that can be distributed, subtract or add. It’s just an answer.
