Answer:
8 %
Step-by-step explanation:
To find the tax rate, we first have to find the tax
4.32 - 4 = .32
The tax rate is found by the tax / total
.32 /4 =.08
To change this to a percent multiply by 100
.08 * 100% = 8 %
Answer:
Yes
Step-by-step explanation:
There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.

Answer:
About 158 times
Step-by-step explanation:
Represent the rate of human heart with H and sparrow's heart with S
![H = 1,533,000\ times](https://tex.z-dn.net/?f=H%20%3D%201%2C533%2C000%5C%20times)
![S = 241,776,000\ times](https://tex.z-dn.net/?f=S%20%3D%20241%2C776%2C000%5C%20times)
Required
Determine how many times faster is S than H
To do this, we simply divide S by H i.e.
![Number = \frac{S}{H}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7BS%7D%7BH%7D)
![Number = \frac{241,776,000}{1,533,000}](https://tex.z-dn.net/?f=Number%20%3D%20%5Cfrac%7B241%2C776%2C000%7D%7B1%2C533%2C000%7D)
![Number = 157.714285714](https://tex.z-dn.net/?f=Number%20%3D%20157.714285714)
--- approximated
<em>Hence, the sparrow's heart beats about 158 times faster than the human hearts</em>
