The equation that best fits the situation is w = 150 * 5 (or the other way around). Since the numbers that would be used are already stated, the equation would be as simple as that. We know that the operation would be multiplication because of the term used "150 for EACH hour" which usually indicates the operation is multiplication.
Hope I helped and good luck!
Tan R = 20/21

answer is C. 0.9524
Answer:
Step-by-step explanation:
(9 + m)(-m + 9) = (9 + m)(9 - m) {(a+b)(a-b) = a² - b²}
= 9² - m²
= 81 - m²
= -m² + 81
