Answer:
Solution given;
Cos (x-
)=
Cos (x-
)=Cos45°
equating corresponding value
(x-
)=45°
x=45°+5/6
x=45.83°
Answer:
The length of the winhspan of aeroplane is 45 m
9(n+7) = 18(n+1)
9n + 63 = 18n + 18
9n = 45
n = 5
answer
n = 5
A. 4x b. 3y c. 8p is the answer
Let x = amount invested in 2% CD and y = amount invested in 3% CD
x + y = 60000
0.02x + 0.03y = 1600
SOLVE THE 1st EQUATION FOR x AND SUBSTITUTE RESULT IN 2nd
0.02(60000 - y) + 0.03y = 1600
1200 - 0.02y + 0.03y = 1600
0.03y = 400
y = 13333.34
x = 46666.66
