Point k is located in quadrant 4 and rotated 90 degrees counterclockwise. which quadrant will k' lie?

The answer is the 1st quadrant because since 90 degress is basically moving it to a quadrant next to it, therefore it would be first because it's counter clockwise

Quadrant four if it is only rotated, if it is moved than it would land in  a different quadrant, but it is being rotated 90 degrees counterclockwise which is down. so the answer is quadrant 1.

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
