Suppose 42 stamps are added to a stamp collection that has 30 stamps. what is the percent of change? round your answer to the nearest tenth, if necessary.

The percentage change in the number of stamps is 140%.

Step-by-step explanation:

We are given the following information in the question:

Number of stamps added = 42

Initial number of stamps = 30

Total umber of stamps = 72

Formula:

Percentage change =

Putting the values, we have:

Hence, the percentage change is 140%.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
