Answer:
ANSWER IS 3
Step-by-step explanation:
Answer:
6days
total cost-$66
additional days-5
Step-by-step explanation:
41+5(x-1)=31+7(x-1)
41+5x-5=31+7x-7
36+5x=24+7x
12=2x
x=6
36+30=66
1. Find the "opposite side," if the angle is 60 degrees and the hyp is 6:
opp opp sqrt(3)
sin 60 deg = ------- = -------- = ----------
hyp 6 2
Cross-multiplying, 2(opp) = 6sqrt(3), so that opp = 3 sqrt(3) (answer)
2. Use the Pyth. Thm. to find the "adjacent side:"
[3sqrt(3)]^2 + x^2 = 6^2, or 9(3) + x^2 = 36, or x^2 = 9, or x = 3.
The lengths of the legs of this 30-60-90 triangle are 3 and 3 sqrt(3).
check: Does 3^2 + [3sqrt(3)]^2 = 6^2?
Does 9 + 9(3) = 6^2? YES
D seems to have the possibility of having the largest range.
Im pretty sure it would be 15.50+(5.00*x) hope i helped have a nice day
