Arianna has a large piece of fabric that she wants to use to make some scarves. the number n of scarves she can make is inversely proportional to the area a of each scarf. if the area of each scarf is 4 square feet, then she can make 15 scarves. if the area of each scarf is 5 square feet, how many scarves can she make?

arianna can make blank scarves.

12 Scarves

Step-by-step explanation:

Given.

number of scarves is N

Area of scarves is A

N ∝

-------------(2)

where k is the constant value of the above equation

If area of each scarves is 4 square feet, then she can make 15 scarves.

If area of each scarves is 5 square feet, then how many scarves can she make.

Area of scarves is 5 square feet that means

Put the A, k value in equation 2

Therefore, Arianna can makes 12 scarves.

mean, 40.6

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
