Answer:
44 answers
Step-by-step explanation:
80% of total questions are answered, ie 80% of 55 questions are answered.
So, (80/100) x 55 , ie 44 questions are answered.
Assuming that all answered questions are correct, 44 answers are correct.
It would be 1/3rd because your last number would be 4 in the equation of 12 sandwiches.
4 1/2(2)=9. Multiply by 2 to get total
9- 3 1/2=z. Subtract 3 1/2 from total to get Z
5 1/2= Z
You are asking for the condition needed for the
<span>two segments to be perpendicular to each other. </span>
<span>If the slope of one segment is m, then the slope of a perpendicular segment would be -1/m </span>
<span>this means that m2 = -1/m and so m2 x m = -1 </span>
<span>If you look carefully at your choices, the 3rd answer involves the two slope and has the -1. It's </span>
<span>the correct answer.</span>
