40 minutes : 1 hour 40 minutes in the simplest form

​

9514 1404 393

  2 : 5

Step-by-step explanation:

You know an hour is 60 minutes, so 1 hour 40 minutes is 60+40 = 100 minutes. Then the ratio is ...

  40 min : 1 h 40 min = 40 min : 100 min = 40 : 100 = 2 : 5

(a common factor of 20 can be removed from 40 and 100)

one that is bigger than 3 1/2

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
