<span>Taking this to a Physics formula of Time equals energy times efficiency over power equals (5670kJ)(0.25) over 800J/s equals 1770 s which gives the solution 30 minutes.
Therefore, it will take 30 minutes for a 68kg person to swim at a fast crawl in order to use all the energy available in a typical fast food meal of a burger, fries, and a drink. I estimated with a 25% efficiency for work capacity at swimming at a fast crawl in this equation.</span>
Answer:3/4=0.75
Step-by-step explanation:
First, 1/2=2/4
Therefore: 1/4+2/4=3/4=0.75
I'm pretty sure its B but I would double check before you put the answer in :)
Answer:
The numbers of measure of music played are 1 and 7
Step-by-step explanation:
Given
Required
Solve for x when s = 80
Substitute 80 for x
Subtract 50 from both sides
Divide through by 10
Reorder
This can be split into
or 
Solve for x
or 
or 
Hence:
<em>The numbers of measure of music played are 1 and 7</em>
Short side length = x
Medium side = x + 7
Long side = 5x
Total 49, so
x + x + 7 + 5x = 49
If you combine like terms:
7x + 7 = 49
Subtract 7 from both sides
7x = 42
Divide both sides by 7
x = 6 inches.
