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:
90 people
Step-by-step explanation:
Total: $775
DJ: $250
Cake: $75
Unknown party guests each getting $5
Let the unknown be x
We can form an equation; <em>DJ + Cake + x number of party guests = $775</em>
<em>250 + 75 + 5x = 775</em>
<em>325 + 5x = 775</em>
Subtract 325 from <u>both sides of the equals sign</u>.
<em>5x = 450</em>
Make <em>x</em> the subject and divide both sides by 5
<em>x = 90</em>
There were 90 party guests.
I believe (7.5, 12.5) is the answer. The answer is where both lines intersect unless there is more to the question.
Given:
There are given that the two paths and one path are 2 miles from the road.
Explanation:
Suppose the distance from the playground to the road is x.
To find the value x, we need to use the cos function;
So,
From the cos function in the given right angle triangle:
Then,
Then,
Final answer:
Hence, the correct option C.
Answer:
<h2>x<=5</h2>
Step-by-step explanation:
x+8+2x <= 2x +13
x+8<= 13
<h2>x<=5</h2>
