Step-by-step explanation:
Two t-shirts that are(31.80) plus a hat(6.20) cost £38.00.
which means that one t-shirt costs £15.90 :)
The equation solved in terms of t would be t = (v - u)/2
Using the slope concept, it is found that his friends are 20 feet apart.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
For the first friend, there is a vertical change of 34 feet and an angle of 34º, hence his position is:
For the second friend, there is a vertical change of 34 feet and an angle of 48º, hence his position is:
The difference is of:
50.4 - 30.6 = 19.8.
Rounding to the nearest foot, his friends are 20 feet apart.

We plug in d as 2, so 8/4 - d would be 8/4 - 2. Now, 8/4 is equal to 2, so 2 - 2 = 0.
