Answer:
75.2 kg
Step-by-step explanation:
His mass now is 80 kg which is 100% of his mass since 100% is the entire amount. He wishes to reduce his mass by 6%.
100% - 6% = 94%
After reducing his mass by 6%, his mass will become 94% of his original mass, 80 kg.
We need to find 94% of 80 kg.
94% of 80 kg = 94% × 80 kg = 0.94 × 80 kg = 75.2 kg
Answer:
x ≈ 14.7
Step-by-step explanation:
Assuming the triangle is right then use Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 15² = 21²
x² + 225 = 441 ( subtract 225 from both sides )
x² = 216 ( take the square root of both sides )
x = 
≈ 14.7 ( to the nearest tenth )
The 1 question is 3 and the second one is 3
Divide 45 by 5 and 5 hours by 5 so it’s 9 miles per hour. So the equation would be: m = 9/h (a fraction)
