Answer:  Yes;   " d/t = r " ; 
__________________________
is, in fact, an equivalent equation to:  "d = r t" .
___________________________
Explanation:
___________________________
  Consider the equation:  "d = rt" (which is, " d = r*t ").

We are asked if:  " d/t = r " an "equivalent equation" [ to: " d = rt "] .
___________________________
Note that:  "d/t = r " is the same as:  ↔  "r = d/t ".

So, given:  "d = rt" ; let us rewrite the equation, by isolating:  "r" on one side of the equation:
_____________________
 → d = r t ;  divide EACH SIDE of the equation by "t" ; to isolate "r" on one side of the equation:
__________________________
 →  d/t = (r*t) / t ;  to get:

   → d/t = r ;  so yes;  "d/t = r"  and:  "d = rt" are equivalent equations.
___________________________
Note:  In practice, these variables are often used in the formula:

"d = rt" ; or, "distance = rate * time" .

The point A has co-ordinates (-4,6) and the point B has co-ordinates (7,-2).
Serhud [2]

Answer:

√185 or 13.60 units to the nearest hundredth.

Step-by-step explanation:

For the points (x1,y1) and (x2,y2) the length between the points is given by:

L = √ [ (x2-x1)^2 + (y2-y1)^]

So here we have:

Length of AB  √ [ (7- - 4)^2 + (-2 - 6)^2]

=  √ (121 + 64)

= √185.

What is the the area of a sector of a circle with a radius of 9 centimeters and formed by a central angle that measures 120
dem82 [27]

Answer:

27π cm²

Step-by-step explanation:

step 1

Find the area of the complete circle

The area of the circle is equal to

A=πr²

we have

r=9 cm

substitute

A=π(9)²=81π cm²

step 2

Remember that the area of complete circle subtends a central angle of 360°

so

using proportion

Find the area of a sector formed by a central angle that measures 120°

81π/360°=x/120°

x=120°*81π/360°

x=27π cm²
