Let All angles be x times multiplied to ratio , so we"ll get :-
2x + 3x + 4x + 5x + 6x = 540°
20x = 540
x = 540/20
⇒ x = 27 ,
so angles are :-
⇒ 2x = 2×27 = 54°
⇒ 3x = 3×27 = 81°
⇒ 4x = 4×27 = 108°
⇒ 5x = 5×27 = 135°
⇒ 6x = 6×27 = 162°
Hence 162° is the greatest angle
A = 210 + 20(h - 7) <== ur equation
if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
Your total profit is $13,000. First you bought the 200 items for $20 each. That costs $4,000. Then you sold $50 of the items at $100 each. That’s $5,000. So already you’re in the green. You’ve already made $1,000 profit. Then you sold the rest of the items at a 20% discount. 150 items multiplied by $80 is $12,000. $12,000 plus the $1,000 equals $13,000 total.
<u>Answer:</u>
2(-5 - 7j) = -10 - 14j
<u>Step-by-step explanation:</u>
Using the distributive property means that we have to multiply both -5 and -7j by 2:
2(-5 - 7j)
⇒ 2 × -5 + 2 × -7j
⇒ -10 - 14j
