a shop stocks six types of phone battery (b1, b2, b3, b4, b5, b6) and a total inventory of 60 phone batteries. assume that the store can get at least 60 of each type of battery. in how many ways can the inventory of 60 batteries be distributed over the six di? erent types if:
(a) there are no restrictions on the number of battery of any type?
(b) the shop must stock at least ? ve batteries of each type?
(c) the shop stocks either b1-type batteries or b2-type batteries, but not both (with no restriction on the type b3, b4, b5, b6 batteries)?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
