I only one person rode a tricycle - that would leave 23 wheels and you cannot make a complete number of bicycles
If 2 people rode tricycles that would leave 20 wheels which would seat 10 bicyclists.
But that totals up to 12 people
3 people riding tricyles leaves 15 wheels which will not complete a number of bicycles
4 people riding tricycles (4 x 3) leaves 14 wheels for 7 bicyclist and is the answer
4 trike riders (12 wheels) + 7 bike riders (14 wheels) = 11 people and 26 wheels
Answer:
99.0 in²
Step-by-step explanation:
The area (A) of the sector of the circle is calculated as
A = area of circle × fraction of circle
= πr² × 
( where r is the radius )
Here r = 9, thus
A = π × 9² × 
= 81π × ≈ 99.0 in²
There are many ways you can start off by solving an equation. In this case, the first operation used in solving this equation would be subtraction. You would have to subtract 5 from each side.
For 90° clockwise rotation, (x, y) becomes (y, -x).
Your rotated point is (2, 3).
Using the identity :
Cos (2a) = 1-2 Sin^2(a)
Therefore :<span>1−2 sin ^2 (22.5∘) = Cos(2a)
= Cos (2 * 22.5) = Cos 45</span>
