Answer:
note: there may be other possible explanations and more body systems can be involved and I can go into much greater detail
1: Nervous system signals your muscles in mouth to abduct and adduct as well as your salivary glands to produce saliva to break down the food, as well as prepare the stomach to digest the food
2: Muscular system moves muscles in mouth to break food down into smaller pieces so there is greater surface area for digestive enzymes to work on the food, then muscles in oesophagus move food to stomach, where stomach muscles churn the broken down food around to speed up digestion
3: Digestive system releases numerous digestive enzymes into the food to break down lipids, carbohydrates and proteins. Small intestines absorb nutrients into bloodstream, and large intestine absorbs water.
4: Excretory system removes excess mostly dry waste through the anus as well as urine from ureter.
So, the first thing you want to find out is how many seconds each person adds to the wait time. Find out how many seconds are in 20 minutes.. 20*60=120. 120/150=0.8 seconds. Each person adds 0.8 seconds to the wait time. Now, multiply that by 240.. 240*0.8=192 seconds. Lastly, find out how many minutes 192 seconds is... 192/60=32 minutes.
I hope I did that right! And if I did, I hope that helped!
2.3 is the other length
Hope this helps :)
Answer:
Step-by-step explanation:
x=o . so the line is parallel to x-axis.
So the line parallel to the line : x = 0
As the perpendicular line will be parallel to y-axis. so the slope of the line parallel to y-axis is undefined.
The area of a triangle is the amount of space on the triangle
The expression that represents the area of the triangle is 
The coordinates of the triangle are given as:



The area (A) of a triangle from its coordinates or vertices are:

Substitute values for x's and y's

Hence, the expression that represents the area of the triangle is
