So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup
65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6
find 160% of 65
'of' means multiply so
1.6 times 65=104
she sold each camera at $104
380 divide by 20
it will take her 19 hours to stamp 380 letters

Step-by-step explanation:
Answer:
The factors of 
is ((x+y)-5)(2x+2y+1)
Step-by-step explanation:
Given polynomial
=>
To Find:
The factors of the polynomial =?
Solution:
Lets assume k = (x+y)
Then can be written as 
Now by using quadratic formula
k =
where
a= 2
b= -9
c= -5
Substituting the values, we get
k =
k =
k =
k =
k =
k= 
k = 
k = 
Solving the RHS we get
Substituting k = x+y
Answer:
cos theta=8/17
8/17=A/H
finding O,
O ² + A² =H ²
(8)²+O²=(17)²
64+O²=289
O²=289-64
O²=225
O=√225
O=15
we know that H=17, A=8, O=15
therefore, the other trigonometric ratios are
sinФ=O/H=15/17
tanФ=O/A=15/8
cosecФ=H/O=17/15
secФ=H/A=17/8
cotФ=A/O=8/15
hope it helps u!
