Charlotte's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric sto
nekit [7.7K]

Answer:

<em>159 feet of fabric</em>

Step-by-step explanation

We are told that 1 curtain is 36inches long

Since 1 foot = 12inches

x foot = 36inches

Cross multiply;

12 * x = 36

12x = 36

x = 36/12

x = 3

Hence 36inches is same as 3 feet

If Charlotte's curtain company wants to make 53 curtains, the length of 53 curtain is expressed as;

1 curtain = 3feet

53 curtain = y

y = 53 *3

<em>y = 159 feet</em>

<em>Hence she will need 159 feet of fabric</em>

lesantik [10]

The actual value is 250.84 .

Formula

Percentage calculation =(given value/total value)*100

let the actual value is "x"

percentage we known is 59 1/5% (59.2%) and 59.2% of x is 148.5.

for the percentage,

x*59.2% =148.5

x*59.2/100=148.5

x=(148.5/59.2)*100

x=(2.5084)*100

x=250.84

The actual value is 250.84 .
