Answer: The will be 1200 miles apart after 2.4 hours.
First draw a picture of an angle of 60 degrees. The vertex is the starting point of the plane and they are flying away from it.
If you drew points for the new positions of the plane and connected them, you would have triangle. The planes are flying at the same speed, so they would be isosceles triangles. And since the vertex angle is 60 degrees, the other angles have to be 60 as well. This makes it an equilateral triangles, meaning all the sides are the same.
So the distance between the planes is equal to the distance that they have flow.
Simply divide 1200 by 500 to get 2.4 hours.
Answer:321\5=64.2
Step-by-step explanation:
You have 3 and 3/5 pounds of water.
To find this, simply multiply 3/5 by 6/1 (multiplying straight across). 6 times 3 is 18 and 5 times 1 is 5. Thus meaning you have 18/5 pounds, which simplified is 3 and 3/5 pounds.
I hope this helps!
Answer:
x = 12
Step-by-step explanation:
Step 1: Write quadratic
x² - 24x + 144 = 0
Step 2: Factor
(x - 12)(x - 12) = 0
Step 3: Find roots
x - 12 = 0
x = 12
Answer:
AB = 14
Step-by-step explanation:
We can add the segments together to find the total
AB + BC = AC
This will allow us to find x
4x+2 + 3x-1 = 22
Combine like terms
7x +1 = 22
Subtract 1 from each side
7x+1-1 = 22-1
7x = 21
Divide by 7
7x/7 = 21/7
x = 3
Now we can find the length of AB
AB = 4x+2 = 4(3)+2 = 12+2 = 14
