Answer:
![25.47](https://tex.z-dn.net/?f=25.47)
Step-by-step explanation:
This root can be rewritten as:
![\sqrt{\frac{6487209}{10000} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B6487209%7D%7B10000%7D%20%7D)
![\sqrt{\frac{6487209}{100^{2}} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B6487209%7D%7B100%5E%7B2%7D%7D%20%7D)
![\frac{1}{100}\cdot \sqrt{6487209}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D%5Ccdot%20%5Csqrt%7B6487209%7D)
Since 6487209 is a multple of 3, the expression can be rearranged as follows:
![\frac{1}{100}\cdot \sqrt{3\times 2162403}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D%5Ccdot%20%5Csqrt%7B3%5Ctimes%202162403%7D)
2162403 is also a multiple of 3, then:
![\frac{1}{100}\cdot \sqrt{3^{2}\times 720801}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D%5Ccdot%20%5Csqrt%7B3%5E%7B2%7D%5Ctimes%20720801%7D)
![\frac{3}{100}\cdot \sqrt{720801}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B100%7D%5Ccdot%20%5Csqrt%7B720801%7D)
720801 is a multiple of 3, then:
![\frac{3}{100}\cdot \sqrt{3\times 240267}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B100%7D%5Ccdot%20%5Csqrt%7B3%5Ctimes%20240267%7D)
240267 is a multiple of 3, then:
![\frac{3}{100}\times \sqrt{3^{2}\times 80089}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B100%7D%5Ctimes%20%5Csqrt%7B3%5E%7B2%7D%5Ctimes%2080089%7D)
![\frac{9}{100}\cdot \sqrt{80089}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B100%7D%5Ccdot%20%5Csqrt%7B80089%7D)
80089 is a multiple of 283, then:
![\frac{9}{100}\cdot \sqrt{283^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B100%7D%5Ccdot%20%5Csqrt%7B283%5E%7B2%7D%7D)
![\frac{9\times 283}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B9%5Ctimes%20283%7D%7B100%7D)
![\frac{2547}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2547%7D%7B100%7D)

Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
<span>So, we're</span> gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.
It’s -7, not -3 because cd is 16 apart and 1/8 is 2 units to the right of c making it -7.
Answer:
I feel like my answer is wrong but all of them are false
first one: it's between 0 and 5
second one: it's between 5 and 10
third one: it's between 10 and 15
but you could also say that they are all true because between the numbers they gave, they are doing what they said
