Answer:
<em>Well, Your answer will be is </em><em>D. 100 feet squared. </em><em>Because, </em>
<em>1. Multiply 10x6 and 10x4.
</em>
<em>
</em>
<em>2. Add 60 and 40, the results from the previous step.
</em>
<em>
</em>
<em>3. You get 100, or 100 feet squared. </em><em>Good Luck!</em>

Answer:
a. 12.8 cm b. 3.125
Step-by-step explanation:
To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.
The solution would be ... m = <span>√2 - 48 over 16. Have a good day :)</span>
Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let
the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is
.
