Step-by-step explanation:
complementary means two angles that add up to 90 degrees
90-38=52
52÷2=26

52+38=90
Answer: The conversion factor between km and m is 1 km = 1000 m, and between hr and seconds, it is 1 hr = 3600 s. Let's first convert 9 km/hr to m/hr.
9 km/hr x (1000 m / 1 km) = 9000 m/hr
Then use the 2nd conversion factor to convert hr to seconds.
9000 m/hr x (1 hr / 3600 s) = 9000 / 3600 m/s = 5/2 m/s
Step-by-step explanation:
The monthly finance charge when the previous balance method is used is $245.83
<h3>How to calculate the amount?</h3>
The finance charge using the previous balance method will be:
= 3000 × 15 × 1/(12 × 100) + 2500/12
= 3000 × 15 × 1/1200 + 208.33
= $245.83
The charge when the adjusted balance method is used will be:
= $3000 - $2500
= $500
The charge when the average daily balance is used will be:
= 3000 × 15% × (1/12)
= 3000 × 0.15 × (1/12)
= $37.50
