Answer:
12.9
Step-by-step explanation:
To solve this, you need to use the Pythagorean Theorem: a² + b² = c²
Substituting the numbers into the formula:
(9.4)² + (8.9)² = c²
(88.36) + (79.21) = c²
167.57 = c²
12.9 ≈ c
81=81•2/2=162/2
81 1/2=162/2+1/2
=163/2
So 81 1/2=163/2=81.5
1hr 30 mins= 60mins+30mins=90mins
140$=90mins
In one minute, they make 140/90=14/9
in 9 hours=9*60mins=540mins
540*14/9=840
therefore,they make 840$ in 9 hours
