More info please... how many minutes can they both use altogether?
Answer:
23.6 (approximate value)
Step-by-step explanation:
- a*a+b*b=c*c Pythagorean thereom
- (21.5)^2 + b*b = (31.9)^2
- b*b= 1017.61 - 462.25
- √b*b= √555.36
- b=23.6(approximate value)
15/2 = $7.5 per hour
7.5 times 5 = $37.50 earned in 5 hours
4 times because if you count 10, 20, 30, 40, so it has to be 4
