Answer:
Step-by-step explanation:
Let's call the balloon's height above the ground and the horizontal distance between the balloon and the first milepost.
If the angle of the depression of this milepost is 24 degrees, we can say the following:
<em>(equation 1)</em>
For the next milepost, the horizontal distance between the balloon and tihs milepost will be and the angle of depression will be 20 degrees, so we can say the following
then, replacing from <em>equation 1</em>
Resolving, we'll find the value of
So, the balloon's height above the ground is 1.99miles
Area = 100Sq/in
Perimeter = 40
Easiest side length would be 10in x 10in = 100sq/in (ie a square)
Instead of a square, the 100sq in could be 100 laid out in a long row: the perimeter therefore would be 100 + 1 + 100 + 1 = 202in. Not a square
Answer:
400%
Step-by-step explanation:
Original wieght = 12
New weight = 60
Change = 60- 12= 48
Change percent = change / original x 100 = 48 / 12 x 100 = 400 %
I hope its right!!!! :)
Answer:
Yes it does change, by 32 cm
Step-by-step explanation:
The new shape has the whole circle and two lines each the same size as the radius; therefore, it increases by 2r
2(16) = 32 cm
