Question

Which of the following is not equivalent to the formula d = rt? (5 points) Select one: a. d over r = t b. r = dt c. d over t = r d. d over rt = 1

Answer 1

the formula d = rt

r = d/t (c. d over t = r)
t = d/r (a. d over r = t)
d = rt (d. d over rt = 1)

so answer
b. r = dt ......not equivalent to the formula d = rt

Answer 2

a,c and d.

Explanation:

a.
`(d)/(r)=t` is equal to

`d=rt` multiplying both sides by r.

b .
`r=dt`

`(r)/(d)=t` is different to
`(d)/(r)=t`.

c.
`(d)/(t)=r` is equal to

`d=rt` multiplying both sides by t.

d.
`(d)/(rt)=1` is equal to

`d=rt` multiplying both sides by rt.
