Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±
/2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since
=
= 17. So b=13.
Answer:
The correct answer is B(2)
Step-by-step explanation:
I did it and somehow got it right.
Based on the amount of your monthly bill, if you lived in England, your bill to the nearest hundredth is $185.82
<h3>How to find your bill in pound sterling?</h3>
You have a monthly bill of $304.72. If this was also your bill in England id you stayed there, it would need to be converted to pounds. The way to do this is by using the exchange rate.
If each British Pound is $1.64 U.S. Dollar, then the value of your monthly bill if you lived in England is:
= Monthly bill in dollars / Conversion or exchange rate
= 304.72 / 1.64
= $185.82

<em>*To solve for a specified variable, you need to isolate that variable onto one side.</em>
<h3>11.</h3>
Firstly, subtract 5r on both sides: ![2p=q-5r](https://tex.z-dn.net/?f=2p%3Dq-5r)
Lastly, divide both sides by 2 and <u>your answer will be
</u>
<h3>12.</h3>
First, subtract z on both sides of the equation: ![-10-z=xy](https://tex.z-dn.net/?f=-10-z%3Dxy)
Next, divide both sides by y and <u>your answer will be
</u>
<h3>13.</h3>
Firstly, multiply both sides by b: ![a=cb](https://tex.z-dn.net/?f=a%3Dcb)
Next, divide both sides by c and <u>your answer will be
</u>
Answer:
B. ![\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B11%7D%2C%20%5Cfrac%7B%5Cpi%7D%7B24%7D%2C%20%5Cfrac%7B3%7D%7B25%7D%2C%20%20%5Cfrac%7B9%7D%7B100%7D)
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:
![W = \frac{3}{25}](https://tex.z-dn.net/?f=W%20%3D%20%5Cfrac%7B3%7D%7B25%7D)
![X = \frac{\sqrt{3}}{11}](https://tex.z-dn.net/?f=X%20%3D%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B11%7D)
![Y = \frac{9}{100}](https://tex.z-dn.net/?f=Y%20%3D%20%5Cfrac%7B9%7D%7B100%7D)
![Z = \frac{\pi}{24}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B%5Cpi%7D%7B24%7D)
Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)
![W = \frac{3}{25}](https://tex.z-dn.net/?f=W%20%3D%20%5Cfrac%7B3%7D%7B25%7D)
![W = 0.12](https://tex.z-dn.net/?f=W%20%3D%200.12)
![X = \frac{\sqrt{3}}{11}](https://tex.z-dn.net/?f=X%20%3D%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B11%7D)
Take square root of 3
![X = \frac{1.73205080757}{11}](https://tex.z-dn.net/?f=X%20%3D%20%5Cfrac%7B1.73205080757%7D%7B11%7D)
![X = 0.15745916432](https://tex.z-dn.net/?f=X%20%3D%200.15745916432)
--- approximated
![Y = \frac{9}{100}](https://tex.z-dn.net/?f=Y%20%3D%20%5Cfrac%7B9%7D%7B100%7D)
![Y = 0.09](https://tex.z-dn.net/?f=Y%20%3D%200.09)
![Z = \frac{\pi}{24}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B%5Cpi%7D%7B24%7D)
Take π as 3.14
![Z = \frac{3.14}{24}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B3.14%7D%7B24%7D)
![Z = 0.13083333333](https://tex.z-dn.net/?f=Z%20%3D%200.13083333333)
--- approximated
List out the results, we have:
![Z = 0.13](https://tex.z-dn.net/?f=Z%20%3D%200.13)
Order from greatest to least, we have:
![Y = 0.09](https://tex.z-dn.net/?f=Y%20%3D%200.09)
Hence, the order of arrangement is:
![Y = \frac{9}{100}](https://tex.z-dn.net/?f=Y%20%3D%20%5Cfrac%7B9%7D%7B100%7D)
i.e.
![\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B11%7D%2C%20%5Cfrac%7B%5Cpi%7D%7B24%7D%2C%20%5Cfrac%7B3%7D%7B25%7D%2C%20%20%5Cfrac%7B9%7D%7B100%7D)
