<span>We have to draw a figure with a perimeter 6 units. If we want to draw a rectangle it can`t be a 3 by 2 because it has a perimeter 2*2 + 2*3 = 4 + 6 = 10 units. It must be a 2 by 1 rectangle ( 2*2 + 2*1 = 4 + 2 = 6 units ).</span>
D would be the closest example to check her answer
Answer:
Given in a bag contains five green marbles, three blue marbles, two red marbles and two yellow marbles
(a)The four colour out comes not equally because the number of four colours balls are different.
(b) Total ball =5+3+2+1=11
Then probability (green) =

Then probability (blue) =

Then probability (red) =

Then probability (yellow) =

The equation is given as W varies directly with u and inversely with d, then the equation is written as:
W = k1u
here k2 is the proportionality constant.
and p = k2

here k2 is the proportionality constant.
Thus, combining both equations we get, p = K

where K = K1*K2, is the proportionality constant.
When dividing a decimal by a decimal, you have to move the decimal before you divide but when you divide with whole numbers, you just divide.
