Determining Unknowns Based on Partially Completed Tables
If $5,860 was raised, which statements are true? Check
all that apply.
Tarin organized this table to determine the number of
adults, a, and children attending a fundraiser based on
the total number of people attending and the total amount
of money raised.

319 people attended.
52 children attended.
201 adults attended.
The total amount of money raised from adult tickets
is double the total amount of money raised from
children's tickets.
The total amount of money raised from adults
attending is more than 10 times the total amount of
money raised from children attending.

10 * 563.67 = 5636.7

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

answer: the answer is d

cool stunts are flippin i think

sitting on a chair

and using stick feet
