Answer:
D. 285
Step-by-step explanation:
Since all angles must add up to 360, if I haven't lost any brain cells, the last angle would need to be 285 degrees.

Since

, it follows that

where the sign depends on the location of the terminal side of the angle. Since the terminal side lies in the fourth quadrant, that means the cosine of the angle is positive, so
Answer:
$4.32
Step-by-step explanation:
18% = 18/100 = 0.18
The amount of tip = 0.18 x $24
The amount of tip = $4.32
Answer:
Step-by-step explanation:
L and W are the length and width of the flag.
"The perimeter of the flag is 500 feet"
2L + 2W = 500
L+W = 250
"The length is 30 feet greater than the width"
L = W+30
You have a system of two equations:
L+W = 250
L = W+30
Substitute W+30 for L:
(W+30) + W = 250
2W + 30 = 250
2W = 220
W = 110 ft
L = W+30 = 140 ft

"C is 400 miles longer than D"
C = D+400
"The sum of their lengths is 5,580 miles"
C + D = 5,580
You have a system of two equations:
C = D+400
C + D = 5,580
Substitute D+400 for C:
(D+400) + D = 5,580
2D + 400 = 5,580
D = 2,590 miles
C = D+400 = 2,990
5 * log ( 6 / 11 ) = 5 * ( log6 - log11 ) = 5 * [ log(2 * 3) - log11] = 5 * (log2 + log3 - log11 ).
