There is no function below.
change 20 in to ft
20/12 = 1 2/3 ft
4 ft x ft
------- = ---------------
5 /3 ft shadow 120 ft
using cross products
4 * 120 = 5/3 x
480 = 5/3 x
multiply each side by 3/5
480 * 3/5 = x
288 ft
Harry's trainer recommends Harry drink
8*(8 oz) = 64 oz
of water per day.
A pint is 16 oz, so this amounts to
(64 oz)*(1 pt)/(16 oz) = 4 pt
of water per day.
By drinking 3 full bottles of water, Harry drank
3*(1 1/4 pt) = 3 3/4 pt
of water.
This amount of water (3 3/4 pt) is less than the 4 pt recommended by the trainer. Harry's claim that he drank the full amount is not true.
assuming the scale is by 1,
a) the slope is rise/run so it rises 3 units and moves 4 units right therefore the slope is 3/4
b) the y intercept is where the line crosses the y axis so by looking at the graph you can tell that the y int is 1
c) and the equation is made up of the slope and the y intercept: y= 3/4x + 1
