Answer:
The statement is not reasonable.
Step-by-step explanation:
Josefina gave away 130% of her stamp collection.
We cannot give more than what we have.
lets understand it mathematically.
suppose i have x stamp.
according to question, i have to give 130% of my stamp collection
130% of x = 130/100 x = 1.3x
so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.
maximum i can give is x stamp.
x stamp in percentage of my total stamp collection which is also x will be
= x/x*100 = 100%
Thus, maximum one can give is 100% of what he has.
Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.

- The equation :
Area = length x width
- Substitute the values in :
Area = (x - 5)(x - 5 + 22)
(Note : the 'x' is for the algebraic expression x in the example above)
- Now you have to simplify the second parenthesis:
Area = (x - 5)(x + 17)
- Now expand :
Area = x^2 + 17x - 5x - 85
- Simplify by collecting like terms :
Area = x^2 + 12x - 85
(Note : x^2 means x squared)
Now you have your answer as:
x^2 + 12x - 85 feet^2

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2
r=x
r=
Area=
r^2
so..
A=
(
)^2
=
(
)
=
(38-x) is perimeter
then
(
)^2
+ (
)^2
then you graph it and it equals
16.716 cm the circumference of the circle
Let g and b represent the numbers of grandstand and bleacher tickets sold.
.. g + b = 5716 . . . . . . . . . total number of tickets sold
.. 65g +40b = 341690 . . value of tickets sold
Using the first equation
.. g = 5716 -b
Sustituting into the second equation
.. 65(5716 -b) +40b = 341690
.. -25b + 371540 = 341690 . . . . . collect terms
.. -25b = -29850 . . . . . . . . . . . . . . subtract 371540
.. b = 1194 . . . . . . . . . . . . . . . . . . . . divide by -25
1194 bleacher tickets were sold.
