Answer:
320 meters
Step-by-step explanation:
x² + 200x = 166400
It's a square, area should be side²
x² + 2(x)(100) = 166400
x² + 2(x)(100) + 100² = 166400 + 100²
(x + 100)² = 176400
x + 100 = 420
Since these are sides, we just consider the positive square root
x + 100 = 420
x = 320m
The slope of Line B is -1/5
In the equation f(n) = 2n - 7
f(11) = 15
Jason: 5/7
Sara: 4/5
Think of it this way: if the total track is a mile, and Jason runs 5/7 of it, he has run 5/7 of a mile. Then Sara runs 4/5 OF 5/7, with "of" meaning "times," so she runs 4/5 x 5/7, which gives you 20/35, which simplifies to 4/7. You can also think of Sara's distance as 80 percent of Jason's. If she runs "80 percent of the sevenths that Jason ran," that means she ran 4 out of his 5 sevenths.
