In January, a puppy weighed 4kg. Three months later, the same puppy weighed 5kg.
What was the percentage increase in the puppy's weight?
​

25%

Step-by-step explanation:

5kg=5000g(a)

4kg=4000g(b)

p=percent

a=b+bxp/100

5000=4000+4000xp/100

5000-4000=40xp

1000=40xp

p=1000/40

p=25

R:25%

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
