Answer:
±1/30
Step-by-step explanation:
Notice that both 16 and 14400 are perfect squares; 16 = 4² and 14400 = 120².
Thus, √(16/14400) = √(4/120)² = ±4/120 = ±1/30.
This is the set of square roots of +16/14400.
The square roots of -16/14400 are ±i(1/30) (which are imaginary roots).
96/6 = 16
16 x 6 = 96
25%
The tip percentage is 100 times the ratio of what you tipped to what you paid.
100 x (1 dollar tip) / (4 dollars paid) = 25%
12.8
Here multiplication is done before addition.
Given
4.8 × 2 + 3.2 ← perform multiplication
= 9.6 + 3.2 ← perform addition
= 12.8
the answer is 10
900 ÷ 90
=> 10
