25x because both can be divided by 25 and x
The textbook is $150 originally, so to find the price of the textbook on sale, multiply the original price by 12% (0.12). Then subtract 12% of 150 from 150.
Subtract 18 from 150.
Multiply the price of the textbook on sale by the sales tax of 8.25% (0.0825). Then add the tax price onto the sale price of the textbook.
Add 10.89 to 132.
The final price of the textbook is $142.89.
Answer:
Radius, r = 26.57 cm and diameter = 53.14 cm
Step-by-step explanation:
Given that,
The circumference of a coin, C = 167 cm
We need to find the radius and the diameter of the coin.
The formula for the circumference of a circle is given by :
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Where
r is radius of coin
![r=\dfrac{C}{2\pi}\\\\r=\dfrac{167}{2\pi}\\\\r=26.57\ cm](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7BC%7D%7B2%5Cpi%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7B167%7D%7B2%5Cpi%7D%5C%5C%5C%5Cr%3D26.57%5C%20cm)
Diameter, d = 2r
d = 2(26.57) cm
= 53.14 cm
Hence, this is the required solution.
d: 1.25
c: .035
b: .70
a: .23
these are just my guesses but if there right then I hope this helps. I don't know it but these are my best affiliations.
