Might be misleading because the commercial says only "80% of dentists use this" instead of saying "100% of dentists use this", but I do like that it's being honest! :-)
Answer:
The correct option is C. 47.10 inches
Step-by-step explanation:
Diameter of the tire rim is given to be 15 inches
So, The radius of the tire rim will be 7.5 inches
Now, we need to find the circumference of the tire rim
And, The circumference of the tire rim is given by the formula :
Circumference = 2·π × radius
⇒ Circumference of the tire rim = 2 × 3.14 × 7.5
⇒ Circumference of the tire rim = 47.1 inches
Therefore, The correct option is C. 47.10 inches
Answer:
7. Approximately 402.7 inches or 2pi times 64
8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.
9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.
Step-by-step explanation:
<h2>Using the quadratic formula</h2>
The quadratic formula can help us solve for x in a quadratic equation:
We can use this when the given equation is organized in standard form: 
<h3>Applying this to the problem</h3>
First we can identify the values of a, b and c:
a = 2
b = 5
c = -4
Plug these values into the quadratic formula:
<h2>Answer</h2>
Therefore, the two possible values of x are:
