Answer:
≈ 10.63
Step-by-step explanation:
Calculate the distance d using the distance formula
d =
with (x₁, y₁ ) = P(- 1, - 1) and (x₂, y₂ ) = L(6, - 9)
d =
=
=
=
= ≈ 10.63 ( to the nearest hundredth )

Answer:
17 green frogs
Step-by-step explanation:
You need to multiply the decimal form of 20% by 85.
To find the decimal form of a percent you take the decimal (20.00) and move it twice to the left (20.00 ---> .2000)
Now, multiply by .2 by 85
(.2)(85) = 17
Therefore, 17 frogs in the pond of 85 frogs are green
