1) You can understand and work with other people's results, you can cooperate with other people in production of goods and check their experiments to see if they are correct.
2) It reduces errors since many people work towards specifying it exactly.
P+ p(.08)= 51.84
p is the original price of the item
if you take 51.84 which is the total amount after taxes are added and divide it
by 1+tax you will get the original price
so if p + p(.08)=51.84 then 51.84/1.08= p
p =48
48+ 48(.08)=51.84
two hundred fourteen and thirteen thousandths
Start by defining your variables. Let the length be L and the width W. Note that W = 2L/3.
Use the Perimeter formula: P = 2W + 2L. Substituting,
P = 2[2L/3] + 2L, or P = 4L/3 + 2L, or P = 4L/3 + 6L/3 = 10L/3 = 210 feet
Then 10L = 630 feet, and L = 63 feet. Thus, W = 2L/3 = 2(63 feet)/3 = 42 feet.
