Answer: 73/ 9 is 8 1/9 do you mean proper?
Step-by-step explanation:
Answer: The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.
Step-by-step explanation:
Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, I will multiply the number of sheets of paper by the weight of a single sheet of paper.
Answer: 1064 square meters
Step-by-step explanation: area of a triangle is a= 1/2xhxw a=1/2xhx28
h= 76 (90-14)
a=1/2x76x28=1064
8x >/= 120
x >/= 15
She must work 15 hours or more to earn at least $120
So legnt=l
width=w
l=-7+3w
l=3w-7
area=66
area=legnth times width or
area=lw
subisutte
area=lw
l=3w-7
66=(3w-7)(w)
66=3w^2-7w
subtrac 66 from both sides
0=3w^2-7w-66
factor
HOW TO
multiply 3 and -66=-198
find what 2 numbers add up to -7 and multiply to get -198
the numbers area 11 and -18
so
3w^2-18w+11w-66=0
factor
(3w^2-18w)+(11w-66)=0
(3w)(w-6)+(11)(w-6)=0
factor using distributive (ab+ac=a(b+c))
(3w+11)(w-6)=0
set them to zero
3w+11=0
subtract 11
3w=-11
legnths cannot be negative so we discard this
w-6=0
add 6
w=6
width=6
legnth=3w-7
length=3(6)-7
legnt=18-7
legnth=11
width=6
legnth=11
