<span>Well first this one you can just count which ones are 9 units away so it could be A becuase -4+-9=-13
Another is B because
-4+9=5
</span>I hope it helps.

Answer: 5,943.6 ounces of copper
4.5 x 25.4 = 114.3 ounces used per week
52 weeks/year
114.3 x 52 = 5,943.6 ounces of copper
<h2>
Measure of the angle between their courses is 95°</h2>
Step-by-step explanation:
Speed of submarine 1 = 25 knots = 28.77 mph
Speed of submarine 2 = 20 knots = 23 mph
Time taken = 3 hours
Distance traveled by submarine 1 = 28.77 x 3 = 86.31 miles
Distance traveled by submarine 2 = 23 x 3 = 69 miles
Distance between them is 100 nautical miles = 115.08 miles
Refer the figure
By cosine formula we have
a = 86.31 miles
b = 115.08 miles
c = 69 miles
Substituting
Measure of the angle between their courses is 95°
After 1 hour they are only 35 miles apart. After 5 minutes they are only 12 miles apart. Then after 2 they intercept.
