There are 160 dolls in the store.
<u><em>Explanation</em></u>
The ratio of the number of teddy bears to the number of dolls is given as 
Suppose, the number of teddy bears 
and the number of dolls 
Given that, the store has 60 teddy bears. That means....
(Dividing both sides by 3)
So, the number of dolls in the store

Answer:
Michael (m) practiced 7 hours and Gen (g) practiced 5
Step-by-step explanation:
g+m+2=12
-2 -2
g+m=10
10 divided by 2 is 5
They both practiced free throws for 5 hours. Michael practiced two hours more that Gen. 5+2=7. Therefore, Michael (m) practiced 7 hours and Gen (g) practiced 5.
Answer:
π
Step-by-step explanation:
Solve for x on the interval [0, 2pi]
Given the equation
Sinx = cosx + 1
Square both sides of the equation
Sin²x = (cos x + 1)²
Sin²x = cos²x + 2cos x + 1
Since Sin²x = 1 - cos²x
1 - cos²x = cos²x + 2cos x + 1
Collect like terms
1-1-cos²x-cos²x-2cos x = 0
-2cos²x-2cos x = 0
-2cos²x = 2cos x
-cosx = 1
cos x = -1
x = arccos -1
x = 180 degrees
<em>Hence the value of x = π</em>
<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>
