Answer:
the second one
Step-by-step explanation:
0.47<0.71
40+20=60
90-60=30
30 divided by 60=0.3333
33.33% makes up the last classroom
Answer:
y = x^2 +2x -35
Step-by-step explanation:
Multiply the binomials. The distributive property is helpful.
y = x(x -5) +7(x -5) . . . . the terms of the first binomial multiplied by the second
= x^2 -5x +7x -35 . . . . eliminate parenthses
y = x^2 +2x -35 . . . . . . collect terms
100 = 10² = 2² × 5², so
100⁹⁹⁹ = (2² × 5²)⁹⁹⁹
100⁹⁹⁹ = 2²ˣ⁹⁹⁹ × 5²ˣ⁹⁹⁹
100⁹⁹⁹ = 2¹⁹⁹⁸ × 5¹⁹⁹⁸
Then
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2¹⁹⁹⁸ × 5¹⁹⁹⁸ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2¹⁹⁹⁸⁻⁹⁹⁹ × 5¹⁹⁹⁸⁻⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2⁹⁹⁹ × 5⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = (2 × 5)⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 10⁹⁹⁹
which is a number with 1000 digits,
