5. a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse
    7^2 + 10^2 = c^2
    49 + 100 =c^2
    149 = c^2....take square root of both sides, eliminating the ^2
     sq rt 149 = c
     12.21 = c.....so the approximate length of 3rd side is 12 m

6. x = number of books bought

7. m < 2 + m < 8 = 180

8. 1000 = 400 + 24x
     1000 - 400 = 24x
     600 = 24x
     600/24 = x
     25 = x <=== 25 months he will have spent $ 1000

Step-by-step explanation

Profit = Sales - Costs

Profits by day:

Mon:

225 - (225*0.12) -9 = 189.0

Tue

260 - (260*0.12) -9 = 219.9

Wed

230 - (230*0.12)-9 = 193.4

Thu

180 - (180*0.12) - 9 = 149.4

Fri

150 - (150*0.12) -9 = 123.0

Total:

189+219.9+193.4+149.4+123 = 874.6
