Answer:
The circumference is 59.66 cm
Step-by-step explanation:
we know that
The circumference of a circle (ring) is given by the formula

If the radius is

substitute in the formula

----> exact value
assume

substitute

300 - 2x = 146, where x is the number
Subtract 300 from both sides.
-2x = -154
Divide both sides by -2.
x = 77
Answer:

if you divide 18 by 3 you get 6
and if you times that my 2 get 12
so your answer is 12 books
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>

No, he is not correct for if they washed 37 cars they would have made a total of 296 dollars washing cars. Because this is an inequality, he needs to get a value equal too or greater than 300 dollars on car washes. Also, because he already has 200 dollars collected, you could write the inequality as "8x is greater than or equal to 300".
