answer:
22 weeks
step-by-step explanation:
- set up a proportion
- use x for how long it would take her
- cross multiply to solve
39 / 2 = 429 / x
429 (2) = 39x
858 = 39x
x = 22
- it would take her 22 weeks
- you can change the units by conversion based on what is asked
In both of the problems, x equals 0 and y equals 1

Hidden right triangle
28 feet tall (1 leg)
the piece that fell over is the hypotonuse
last leg is what we need to find
81-28=53
a²+b²=c²
a and b are legs and c is the hypotonuse
given
on leg is 28 and the hypotonuse is 53
th othe leg is b
28²+b²=53²
784+b²=2809
minus 784 from both sides
b²=2025
sqrt both sides
b=45
answer is 45ft
