How many different ways can you add two odd numbers to get a sum of 20 and add examples

Gre4nikov [31]

We can add only odd numbers. Let's assume that we're dealing ONLY with positive numbers. Which two odd numbers add to 20? 1+19 qualifies.
So do 3+17, 5+15, 7+13, 9+11.

The angle measures of quadrilateral RSTU are shown.

monitta

If <R=<T
2x=x+35
x=35
<R=<T=2*35=70

<S=3x-35=3*35-35=2*35=70

but <R+<S+<T+<U=360
<U=360- (70+70+70)
<U=360-210
<U=150

Answer:

L = 882/121 feet

Step-by-step explanation:

Set the appropriate variables in the equation to the given values and solve for the unknown.

$T=2\pi\sqrt{\dfrac{L}{32}}\\\\3=2\left(\dfrac{22}{7}\right)\sqrt{\dfrac{L}{32}} \qquad\text{fill in given values}\\\\ \dfrac{3\cdot7}{44}=\sqrt{\dfrac{L}{32}} \qquad\text{multiply by $\dfrac{7}{44}$}\\\\ \left(\dfrac{21}{44}\right)^2=\dfrac{L}{32}\qquad\text{square both sides}\\\\ \dfrac{32\cdot441}{1936}=L \qquad\text{multiply by 32}\\\\ \boxed{L=\dfrac{882}{121}}\qquad\text{reduce the fraction}$

That's about 7.3 feet. (You can compare this to what you know about the time it takes for a cycle when swinging on a swing set.)
