a reduced fat cookie contains 11g of fat per serving. in order for food to be termed 'reduced fat', it must have at least 20% le
Svetllana [295]

Personally, I did this in a kinda weird way but I think that it should be correct

-How I figured the answer out-

I took 11g and wrote 80% next to it, because after all it has 80% less fat than the regular cookie.

Then, I scaled it down to 10% by dividing by 8, which got me

1.375g = 10%

And finally, I multiplied by 10 to now have 100% (meaning, a regular serving size cookie) and be left with the result: 13.75g

-The answer-

13.75g   (don't forget to write the units)

Have a great day :)

butalik [34]

We have been asked to find

In which quadrant does the terminal side of the angle 257° lie?

As we know that in the first Quadrant angle is from 0 to 90

In the second Quadrant angle is from 90 to 180

In the third Quadrant angle is from 180 to 270.

In the fourth Quadrant angle is from 270 to 360.

Hence the angle 257 will lie in the third Quadrant.
