Answer:
2/5 yards of fabric
Step-by-step explanation:
A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow?
5 identical pillows = 2 yards of fabric
1 pillow = x yards
Cross Multiply
x yards × 5 pillows = 2 yards × 1 pillow
x yards = 2 yards × 1 pillow/5 pillows
x yards = 2/5 yards of fabric
Therefore, 2/5 yards of fabric was used for 1 pillow
The complex conjugate root theorem states that if a+bi (with a and b being numbers) is a root, then a-bi is also a root. Plugging that in here, this means that 5-6i is also a root

Step-by-step explanation:
Answer:
60 km
Step-by-step explanation:
The closure speed of the trains is 30+30 = 60 km/h. Since their initial distance apart is 60 km, it will take 1 hour for them to collide.
The bird flies for 1 hour at 60 km/hour, so flies a total distance of 60 km before being crushed in the collision.
