Answer:
There will be 20 trumpet players in the band this year.
Answer:
n = -11
Step-by-step explanation:
Assuming you need to solve for n:
12 - n = 23 (Given)
-n = 11 (Subtract 12 on both sides)
n = -11 (Divide -1 on both sides)
190 and 65 because no negatives are allowed
Answer:
85 feet
Step-by-step explanation:
60^2+60^2=7200
square root of 7200 is 85
Answer:
The square root is 1.90
Step-by-step explanation:
Given
![x = \sqrt{3.6}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B3.6%7D)
Required
Find x
Express 3.6 as 36/10
So, we have:
![x = \frac{\sqrt{36}}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B%5Csqrt%7B36%7D%7D%7B%5Csqrt%7B10%7D%7D)
This gives
![x = \frac{6}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7B%5Csqrt%7B10%7D%7D)
Rationalize
![x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7B%5Csqrt%7B10%7D%7D%2A%5Cfrac%7B%5Csqrt%7B10%7D%7D%7B%5Csqrt%7B10%7D%7D)
![x = \frac{6\sqrt{10}}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%5Csqrt%7B10%7D%7D%7B10%7D)
Using a calculator
![\sqrt{10} \approx 3.16](https://tex.z-dn.net/?f=%5Csqrt%7B10%7D%20%5Capprox%203.16)
So, we have:
![x = \frac{6*3.16}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%2A3.16%7D%7B10%7D)
![x = \frac{18.96}{10}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B18.96%7D%7B10%7D)
![x = 1.896](https://tex.z-dn.net/?f=x%20%3D%201.896)
Approximate
![x = 1.90](https://tex.z-dn.net/?f=x%20%3D%201.90)
