A student estimated a mass to be 40 g. After carefully measuring, she found the actual mass to be 45 g. What is the percent of error? Help me plz

Step-by-step explanation:

Well percent error is calculated by the value you got divided by the actual value times 100%.

So

40/45 x 100% = 88.8888888889%

You can round this to 88.89 % or something

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 .
