I think option two is the correct one, because 1 and two contradict eachother and 4 doesn't make sense
Answer: x = 13.5
3/4 = x/18
⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Answer:
24 yards, $77.40
Step-by-step explanation:
1) brown braid : 4*2.40 = $16.80
black lace : 7*2.40 = $29.40
gold ribbon : 13*2.40 = $31.20
2) 4 + 7 + 13 = 24 yards <
3) 16.80 + 29.40 + 31.20 = $77.40 <
The Cartesian equivalent of the polar coordinates (r, theta) is
(r cos t, r sin t), where t = theta.
So, (2, 3pi/4) becomes
(2 cos(3pi/4), 2 sin(3pi/4))
(2 • -sqrt{2}/2, 2 • sqrt{2}/2)
Answer: (-sqrt{2}, sqrt{2})
Done.
Note: sqrt = square root for short.
The as were is XY=22/sin(4)
