I did it but I cant upload the image ...
the answer is 5x + 3 remainder 8
Edited: Ok, managed to upload it now.
Answer:
81 degrees
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
20 = 2*pi*r
Divide each side by 2pi
20/2pi = 2*pi*r/2pi
10/pi =r
We know the arc length can be found by
s =r theta where theta is in radians
9/2 = 10/pi *theta
Multiply each side by pi/10 to isolate theta
9/2 * pi/10 = pi/10 *10/pi *theta
9*pi/20 = theta
We need to convert to degrees
9*pi/20 * 180/pi
81 degrees
You could pick just about anything 3/8 is not the same thing as 5/7 and neither is 3/4
Something that is equivalent would be something like 10/14 or 20/28
<em>A) 21</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>
</em>
<em>multiples of 7 = all form numbers n×7 ; n ∈ N</em>
<em>21 = 3×7</em>
<em>29 = prime number</em>
<em>27 = 3³</em>
<em>23 = prime number</em>
<em>
</em>
<em><u>the only multiple of 7 is </u></em><em><u>21</u></em>

Answer:
15%
Step-by-step explanation:
Given that,
Initial earning is $20 for each lawn and this summer she raised her price to $23 per lawn. We need to find the percent increase of peggy's charges. It can be given by :
Putting the values in above formula, we get :
So, there is 15% increase in the peggy's charges.
