Answer:
59/9
Step-by-step explanation:
d=100. 12/4=3 min/lap
12mins 4 laps. 100/180= 59/9
R=50
2(pie)(50)=100(pie)
Answer:
9 months
Step-by-step explanation:
$500 - $240 = $260
$260/$30 = 8.67(3s.f.) ≈ 9 months
Recheck:
Balance after 9 months = 240 + (30×9) = 240 + 270 = $510
∴ $510 > $500
Answer:
C) 3/5
Step-by-step explanation:
Have you heard of this way to memorize the trig ratios?
SOH-CAH-TOA (Say it out loud so you remember it.)
It represents these ratios:
Sine = opposite side / hypotenuse
Cosine = adjacent side / hypotenuse
Tangent = opposite side / adjacent side
In this problem, cos C = adj / hyp = BC / AC = 24 / 40.
That simplifies to 3/5
The answer would either be (-3,5), (5,-3), (9,-7), or (-7,9). I forget where the <em>x </em>and <em>y</em> go, but those are your answer choices.
