Answer:
33.33%
Step-by-step explanation:
The percentage was a decrease.
Let the percent be x.
60 × (1 - x%) = 40
60 × (1 - x/100) = 40
1 - x/100 = 40/60
-x/100 = 40/60 - 1
-x/100 = -1/3
x/100 = 1/3
x = 1/3 × 100
x = 33.33333
I believe it’s C, hopefully this helps !!
FORMULA:
- Pythagorean property —: h² = b² + p², where h = hypotenuse, b = base, p = perpendicular.
ANSWER:
By pythagorean property,
- x² = 25² + 100²
- x² = 625 + 10000
- x² = 10625
- x = √10625
- x = 103 cm rounded.
Hence, the length of x is 103 cm.
