Hey there! :D

Think of this like a triangle. The dock is 15 feet above ground. It is the side of the triangle. The line connecting the bottom of the dock to the base of the conveyor belt is 40 feet. This is like the base. 

The conveyor belt itself is at a diagonal, and should be the hypotenuse. 

Use the Pythagorean theorem. 

a^2+b^2=c^2

15^2+40^2= c^2 

225+1,600= c^2

Add the values together. 

1,825= c^2

Find the square root of 1,825. 

c= 42.7 (rounded to the nearest tenth) 

The conveyor belt is 42.7 feet long.

I hope this helps!

kramer

Answer:

V=144\ cm^3

Step-by-step explanation:

#We use the base diagonal and the height diagonal to calculate the beam's height:

h=\sqrt{13^2-(4^2+3^2)}\\\\h=12\ cm

#The volume of the beam can then be calculated as:

V=lwh\\\\=4\times 3\times 12\\\\=144\ cm^3

Hence, the beam's volume is 144\ cm^3

Over 2 years, how much more does $2000 in a savings account with an APR of 4.2% compounded semiannually earn in interest than th
Reptile [31]
Below is the solution:

 <span>A = 2000[1 + (.042/2)]^(2*2) 
A = 2173.366476962 
A = 2173.37 
I = 2173.37 - 2000 
I = 173.37 

A = 2000[1 + (.036/12)]^(12*2) 
A = 2149.0790382667085294501721261072 
A = 2149.08 
I = 2149.08 - 2000 
I = 149.08 

173.37 - 149.08 = 24.29</span>
