Isabella knit a total of 12 centimeters of scarf over 3 nights. How many nights will Isabella have to spend knitting in order to knit a total of 16 centimeters of scarf? Assume the
relationship is directly proportional.
nights

4 nights

Step-by-step explanation:

12 centimeters over 3 nights

12 divided by 3 is 4

Each night she knitted 4 centimeters of the scarf

The next night she will knit  more centimeters 12 + 4 = 16

So she would take 4 nights to knit a total of 16 centimeters

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
