a. Vince
Step-by-step explanation:
The perimeter of this shape is 92 in.
The perimeter of a shape is equal to the sum of all its side lengths. That means to find the perimeter, we need to add up the lengths of all the sides.
35 in. + 35 in. + 11 in. + 11 in. =
=70 in. + 22 in. =
=92 in.
That means that the perimeter of this shape is 92 in.
Tanh x = 12/13
1) Calculate cosh x:
cosh² x = 1/(1-tanh² x) →→ 1/[1-(12/13)²] = 1/(1-144/169) = 1/[(169-144)169]
cosh²x = 169/25 and cosh x = + or - 13/5
2) Calculate sinh x
sinh x/cosh x = tanh x →→sinh x = (cosh x)(tanh x)
sinh x = + or - (13/5)(12/13) →→sinh x= + or - 12/5
From here onward you can calculate easily coth x, sech x, csch x

Answer:
900 people preferred hamburgers.
Step-by-step explanation:
540/x=60/100
cross multiply
60x=54,000 then
60x/60=54,000/60
x=900
so 900 people preferred hamburger
