Fabric is sold by the yard and many fabrics are 48" wide (4feet). Designers calculate the square feet needed for a garment in order to decide how much fabric to buy. A Designer is creating skirts as samples for 6 models in an up coming fashion show. Each skirt requires 42 square feet of fabric. The cost of the fabric is $12.57 per yard. How many yards of material does the designer need for the 6 skirts?

How much will ALL the fabric cost?

What is the cost pf the fabric for ONE skirt?

How many yards of material does the designer need for the 6 skirts? = 12

How much will ALL the fabric cost? = $150.84

What is the cost of the fabric of ONE skirt? = $12.57

Step-by-step explanation:

How many yards of material does the designer need for the 6 skirts?

First, it says that the yard is 48" wide aka 4 feet. But since it's asking for a total of 6 skirts, you multiply the yard by the number of skirts. Let's try to multiply 48 with 6.

  48

x   6

288

So it will be 288 yards of material but we need to multiply 4 with 6.

  4

x 6

24

So as you can see, 24 is 12 times as many as 288.

If you multiply 24 with 12, you will get the result of 288.

So the answer is 12 yards of material.

How much will ALL the fabric cost?

First, it says that the cost of the fabric is $12.57 per yard.

So, since we got our answer as 12 for our first question, we gotta multiply $12.57 with 12.

    12.57

x        12

 150.84

So the answer is $150.84.

What is the cost of the fabric for ONE skirt?

First, again we check that it's $12.57 per yard.

So, if it's for only one skirt, it will be $12.57.

It says that the fabric cost $12.57 and for one skirt.

Hope this helped! I tried to help though. I didn't read the whole thing but I tried to solve your 3 questions :) !

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
