The equation for the circumference is 2 pi r. You have the circumference given.

Now, divide that by pi to get 2 r.

This is approximately 11.63.

Now, divide that by 2 to get the radius.

Radius = 5.14 yards.

How to solve x=6y-11 and 3x-2y=-1 by substitution
vagabundo [1.1K]
Substitute x into the second equation:
3(6y-11)-2y=-1
18y-33-2y=-1
16y=32
y=2
Then put the y value into the first equation to get x:
x=6(2)-11
x=1
There you go!

nalin [4]

In this problem, you must use SohCahToa which basically means:

Sin - opposite over hypotenuse

Cosine - adjacent over hypotenuse

Tangent - Opposite over hypotenuse


So in this picture we have 4 -which is on the opposite side of x - and a 5 -which is the hypotenuse of the triangle. This means we must use sin.

Using a calculator you put in:

sin^{-1} (\frac{4}{5} )

Your answer is 53.13 degrees

choli [55]

Answer:

Here is the way to get the answer

Step-by-step explanation:We use the formule: t=S/v. So:

+ t1= 160/100 = 8/5 hrs = 5760''

+ t2= 160/90 = 16/9 hrs = 6400''

=> t2-t1= 6400 - 5760 = 640'' = 10'40''
