Use the law of cosines. Let 
be the distance between the docks, which forms a third leg of a triangle for which the angle opposite it has measure 45 degrees. The other two legs have lengths 400 ft and 500 ft. So
Answer:
-5.126
Step-by-step explanation:
PEMDAS
-4.326 + (-0.32) ÷ 0.4
<u>-0.32 ÷ 0.4</u>
= -0.8
<u>-4.326 + (-0.8)</u>
= -4.326 - 0.8
= -5.126
When 'y' is directly proportional to 'x', we express this by
y = kx
where 'k' is the constant, which we need to work out first
Cost of circular mirrors = (k) (diameter)²
50 = k(60)²
50 ÷ 3600 = k
the proportional formula is
y = (1/72)x²
The cost of the mirror when diameter = 90cm
y = (1/72) (90)²
y = 112.5
Answer: $112.50
Volume formula : length x width x height
Therefore, 24 x 10 x 16
=3840 in3
