Answer:
b = 12
Step-by-step explanation:
The mistake Megan has made is that she has squared the lengths and then added it instead of taking away the squared length's. The method she used was to work out the hypotenuse, so the correct method would be as follows:
a² + b² = c²
→ Substitute in the values
5² + b² = 13²
→ Simplify the equation
25 + b² = 169
→ Minus 25 from both sides to isolate b²
b² = 144
→ Square root both sides to find the value of b
b = 12
Answer:
Her average speed for the trip was 48 mph.
Step-by-step explanation:
Rina drove 1 hour at the speed = 45 mph
Distance covered in 1 hour = 45 miles
she drove 1.5 hours at the speed = 50 mph
Distance covered in 1.5 hour = 50 × 1.5 = 75 miles
Total distance covered by Rina = 45 + 75 = 120 miles
Total time taken by Rina = 1 + 1.5 = 2.5 hours
Average speed = Total distance / Total time
= 120 ÷ 2.5 = 48 mph
Her average speed for the trip was 48 mph.

Step-by-step explanation:
YEAR 1: 40000 X .03 = 1200 40,000 + 1200 = 41200
YEAR 2: 41,200 X .03 = 1236 41,200 + 1236 = 42436
YEAR 3: 42436 X .03 = 1273.08 42436 + 1273.08 = 43709.08
YEAR 4: 43709.08 x .03 = 1311.27 43709.08 + 1311.27 = 45020.35
YEAR 5: 45020.35 X .03 = 1350.61 45020.35 + 1350.61 = 46370.96
YEAR 6: 46370.96 X .03 = 1391.13 46370.96 + 1391.13 = 47762.09
YEAR 7: 47762.09 X .03 = 1432.86 47762.09 + 1432.86 = 49194.95
YEAR 8: 49194.95 X .03 = 1475.85 49194.95 + 1475.85 = 50670.80
YEAR 9: 50670.80 X .03 = 1520.12 50670.80 + 1520.12 = 52190.92
YEAR 10: 52190.92 X .03 = 1565.73 52190.92 + 1565.73 = 53756.65
YEAR 11: 53756.65 X .03 = 1612.70 53756.65 + 1612.70 = 55369.35
YEAR 12: 55369.35 X .03 = 1661.08 55369.35 + 1661.08 = 57030.43
YEAR 13: 57030.43 X .03 = 1710.91 57030.43 + 1710.91 = 58741.34
YEAR 14: 58741.34 X .03 = 1762.24 58741.34 + 1762.24 = 60503.58
YEAR 15: 60503.58 X .03 = 1815.11 60503.58 + 1815.11 = 62318.69
YEAR 16: 62318.69 X .03 = 1869.56 62318.69 + 1869.56 = $64,188.25 = $64188
$806275, hope this helps!
