Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD
For AB:
So:
For CD:
So:
For Lines to be parallel, the slope must be equal:
i.e.
This condition is not true because:
For Lines to be perpendicular, the slope must be:
This implies:
<em>Hence, the lines are perpendicular</em>
Answer:
18/5 = 3.6 so we would round the number to make it 4 times
Step-by-step explanation:
divide 18 by 5.
let's say you had 18 apples and you have to give 3 people the same amount of apples. If we give 5 apples to each of the 3 people, we would have given them a total of 15 out of 18 apples, that would leave 3 apples. You would then give each person 1 of the 3 apples so that all the people have the same amount of apples.
So if you count the total apples each person had, it would be 4. So we know that the answer is 4 because each apple represents how many times the apples to apples each.
the circumference of a circle is 2pie times radius
Answer: -42 is the answer.
