Marsha spent $38.64 on 4 yards of string for a science project. She then discovers she needs an additional 6 yards. How much should she expect to pay for the extra yards of string?

$38.64/4 = $9.66

its $9.66 for each yard

so $9.66 multiplied by 6 = $57.96

she should expect to pay $57.96 extra.

Step-by-step explanation:

$57.96

Step-by-step explanation:

4 yards is $38.64, divide it by 4 to get the price for 1 yard then times it by 6

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
