Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:
Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:
So, it turned 785.4 feet with 1 rotation.
The correct answer is A

Determine the number of boys and girls
We have to convert the ratio to fraction;
Number of girls can be calculated as:
Answer:
x = -5.83, -0.17
Step-by-step explanation:
Quadratic Formula:
Since we are given <em>a</em> = 1, <em>b </em>= 6, and <em>c</em> = 1 from our quadratic, we use the Quadratic Formula:
Step 1: Plug in variables
Step 2: Solve
Step 3: Evaluate to decimals
When you do so, you should get x = -5.82843 and -0.171573
