What part of an hour elapses from 3: 12 p. m. to 4: 30 p. m.?

of an hour.

Step-by-step explanation:

1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)

2. Therefore, you must make the following addition:

This is 78 minutes out of 1 hour (60 minutes).

3. Therefore, you have the following fraction:

4. Now, you must reduce the fraction:

5. The answer is 13/10 on an hour.

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 .
