9.09%
Step-by-step explanation:
John Salary = $80,000.
Raise = 10% of salary = 10/100*80,000=$8000
New Raised Salary = 80000 + 8000 = $88000
Cut back = 80000
Decrease % = (88000-80000)/88000*100
Decrease % = 8000/88000*100
Decrease % = 9.09%

Answer:
24 centimeters squared(cm²)
Step-by-step explanation:
The triangle below has been reduced by a scale of 0.4.
A large triangle has a base of 30 centimeters and height of 10 centimeters.
Hence, reducing the large triangle by the given scale ratio, we have :
Height = 10cm × 0.4 = 4cm
Base = 30cm × 0.4 = 12 cm
Hence, the area of the smaller triangle
= Area = 1/2 × Base × Height
Height = 4 cm
Base = 12 cm
Area = 1/2 × 4 × 12
= 24 cm²
