Answer:
Minimum number of weeks = 4
Step-by-step explanation:
Charles earns $5 each week .Also he makes $15 each week by mowing his neighbours lawn.
Thus , in total , he earns a total of $20 each week.
We have to find the minimum number of weeks needed to make $75 .
Number of weeks required = 
= 
=3.75
Since the number of weeks, W, is an integer, choose the next highest integer.
Hence the minimum number of weeks required = 4
Is there an image with this question, if so attach it to the question next time.
<span>a.) Let x be the number of tickets sold before the event and y the number of tickets sold on the day of the event. Then x + y =< 800 and 6x + 9y >= 5000. (b.) Suppose the club sold 440 tickets before the event, i.e. x = 440, maximum number of tickets remaining to be sold = 800 - 440 = 360. Maximum amount realized from the sales supposing all tickets were sold = 6(440) + 9(360) = 2640 + 3240 = $5880 which is greater than $5000. Therefore, it is possible for the club to sell enough additional tickets on the day of the show to meet the expenses of the show.</span>
Answer:
Step-by-step explanation:
By inscribed angle theorem:
![m\angle R = \frac{1}{2} [360 \degree - (120 \degree + 140 \degree)] \\ \\ m\angle R = \frac{1}{2} [360 \degree -260 \degree] \\ \\ m\angle R = \frac{1}{2} \times 100 \degree \\ \\ m\angle R = 50 \degree \\ \\](https://tex.z-dn.net/?f=m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5B360%20%5Cdegree%20-%20%28120%20%5Cdegree%20%2B%20140%20%5Cdegree%29%5D%20%20%5C%5C%20%20%5C%5C%20m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5B360%20%5Cdegree%20-260%20%5Cdegree%5D%20%20%5C%5C%20%20%5C%5C%20%20m%5Cangle%20R%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20100%20%5Cdegree%20%20%5C%5C%20%20%5C%5C%20%20m%5Cangle%20R%20%20%3D%2050%20%5Cdegree%20%20%5C%5C%20%20%5C%5C%20)
