Step-by-step explanation: Hope this helped. Let me know if it did.
Answer: 80
1 hour= 60mins
So to know how many words can she type in 1 min, we do the math "4800 : 60"
By the pythagorean theorem the diagonal length will be:
d^2=x^2+y^2 and since this is a square x=y so
d^2=2x^2 and since d=15
225=2x^2
x^2=112.5
x=√112.5 yds
x≈10.6 yds (to nearest tenth of a yard)
The y intercept is the y value when x is 0.
In the table when x is 0 y = 4
The y-intercept is 4
Answer: A. 4
