Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
It’s -10
Explanation: 8 x 5= 40
40/-4= -10
Based on the number of pages read and the time it was read in, the number of pages read per day was <u>44 pages. </u>
Marion read 616 pages and did this in 14 days.
She read the same number of pages each day so the number of pages read per day was:
<em>= Number of pages read in total / Number of days </em>
= 616 / 14
= 44 pages
In conclusion, she read 44 pages per day.

Hi!
Let's first expand the cotangent of theta.
You'll probably know that tangent will be "y/x", or 
, and cotangent is the reciprocal of this, meaning that it is "x/y" or 
.
That means that we are now given this equation.
That'll multiply to:
We'll want a common denominator to add by multiplying 
to both top and bottom of the second term:
Pythagorean Identity states that 
, so substitute that in:
Which simplifies to:
Hope this helps!
