Answer:
Step-by-step explanation:
a). Since, 20% of the total diagram is represented by one fifth part of the total length.
Therefore, by adding all parts we will get 100% weight of the adult puppy.
20% of the part = 9 pounds
So the total weight of the adult puppy = 9 + 9 + 9 + 9 + 9
= 45 pounds
b). Weight of the puppy = 9 pounds
Weight of a adult = 45 pounds
Therefore, fraction that represents the weight of the puppy as compared to the weight of an adult =
=
30=-5(6n+6)
-30=5(6n+6)
-30=30n+30
-1=n+1
n=-2

Answer:
Step-by-step explanation:
Calculate the length (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)
d =
=
=
= ≈ 4.1 ( to 1 dec. place )
