The directions on a sewing pattern say to cut an extra 12% of fabric to account for error. chole needs 0.8 yard of fabric to make a skirt, so she cuts 0.096 yard. did chole cut the corect amount of fabric? why or why not?

Step-by-step explanation:

According to the problem, Chloe needs 0.8 yards of fabric to make a skirt. However, they ask her to cut an extra 12%. To find the right answer, we have to calculate the 12% of 0.8, and then sum it with the standard yards for the skirt. That is

This means that Chloe cut the wrong amount of fabric, because she only cut the 12% without adding the initial 0.8 yards.

The right amount of fabric is 0.896 yards.

step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
