Hi there! For this, we can simply divide 20.50 by 410 to find the tax rate. 20.50/410 is 0.05. That's in decimal form. Multiply by 100 to get the percent form. 0.05 * 100 is 5. That's the number in percent form. The sales tax rate is 5%.
First of all, let's convert all the measures to the same unit: 4 feet are 48 inches.
Now, as the wheel turns, there is a proportion between the angle and the distance travelled: for example, when the car moves forward a whole circumference, the angle will be 360°. Conversely, if the wheel turns 180°, then the car will move forward a distance which is half the circumference of the wheel, and so on.
Since the radius is 16 inches, the circumference will be
![C=2\pi r = 32\pi](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%20%3D%2032%5Cpi)
So, we have the following proportion:
![360\div 32\pi = x \div 48](https://tex.z-dn.net/?f=360%5Cdiv%2032%5Cpi%20%3D%20x%20%5Cdiv%2048)
that you can read as: "if an angle of 360 corresponds to a distance travelled of
, then the unknown angle x corresponds to a distance travelled of 48 inches.
Solving for x, we have
![x = \dfrac{360\cdot 48}{32\pi} = \dfrac{17280}{32\pi} = 171.887338539\ldots \approx 171.9](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7B360%5Ccdot%2048%7D%7B32%5Cpi%7D%20%3D%20%5Cdfrac%7B17280%7D%7B32%5Cpi%7D%20%3D%20171.887338539%5Cldots%20%5Capprox%20171.9)
3terms = trinomial (7a^2, 4a, -12)
Degree of each term 2nd, 1st, constant
Largest degree: 2nd
Answer: 2nd degree trinomial
Answer:
you know that the coefficient of x is one so to find x the real equation is x+27= -12 so u cross over 27 to the right it will be -12-27=-39.
Is the the line veritcal or horizontal,if its vertical then the slope is undefined, if its horizontal then it should be zero leading to y=4÷9 or y=0.44
