The correct answer is 45ft(along the ground)
Explanation:
It is making the right angled triangle as one half is 28 feet tall(vertically straight); the other half which fell over some distance is the hypotenuse. To find its length:
Hypotenuse = 81 - 28 = 53
Now that we have hypotenuse and the vertical length (perpendicular), we can find the base( along the ground) using Pythagoras theorem:
c^2 = a^2 + b^2
c = hypotenuse
a = perpendicular
b = base
53^2 = 28^2 + b^2
b = 45ft (along the ground)
Answer:
x+12 x-15 x-8 x-30 x+15
Step-by-step explanation:
D=-1
-15d=15 so -d=1 so d=-1
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
