The answer is actually d lol the idiot above me was right
The problem says that <span>Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:
</span>
Tan(α)=Opposite leg/Adjacent leg
α=30°
Opposite leg=x
Adjacent leg=200 feet
When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200
You must clear "x":
x=200xTan(30°)
Therefore, the value of "x" is:
x=115 feet
<span>
How high above the ground the is the helicopter?
The answer is: 115 feet</span>
Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board =
feet
Also, she need to cut the board into 11 pieces.
by unit rate definition:

or

Therefore, 1/4 feet long should each pieces be.
Answer:
359/4
Decimal: 89.75
Step-by-step explanation:
So the equation you're going to be using is mass = density x volume
So the volume of your block is 35cm^3, and your density is .85g/ml
so your equation would be
mass=.85g/ml x 35cm^3
your final answer is 29.75g/cm^3
Hope this helps :)
