The directions on a sewing pattern say to cut an extra 15% of fabric to account for error. Chloe needs 0.75 yardof fabric to mak
Vlada [557]

Answer: D. Chloe did not cut enough fabric because she only cut the amount of extra fabric.

Step-by-step explanation:

From the question, we are informed that a direction on a sewing pattern say to cut an extra 15% of fabric to account for error and that Chloe needs 0.75 yard of fabric to make a skirt.

Based on the information given in the question, the extra fabric will be:

= 15% × 0.75

= 15/100 × 0.75

= 0.15 × 0.75

= 0.1125

Therefore, the correct amount of fabric to cut will then be the amount of yard needed for the skirt plus the extra. This will be:

= 0.75 + 0.1125

= 0.8625 yards

Based on the above calculation, Chloe did not cut the correct amount of fabric as she only cut the amount of extra fabric.

Answer:

9 cats

Step-by-step explanation:

x = cat

y = dog

Set up equations.

x + y = 30

4.5x + 8.5y = 219

Multiply first equation by 4.5 and subtract.

4.5x + 4.5y = 135

-(4.5x + 8.5y = 219)

-4y = -84

y = 21

Substitute this y value into the first equation

x + y = 30

x + 21 = 30

x = 9
