So 15.90 is almost $16 so you will round up...

and 18 is almost 20

so that would be 20%of $16

so the best estimate would be around $3-$4

Sarah needs 10 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabri
Aleks [24]
<h2>Hello!</h2>

The answer is:

The fabric will cost $4.58

D.$4.58

<h2>Why?</h2>

Since it's a conversion exercise, we need to pay special attention to the conversion procedure.

From the statement we know that:

1ft=0.305m

So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.

We have that:

10*1ft=10*0.305m\\\\10ft=3.05m

Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:

\frac{1m}{1.50(dollars)}=\frac{3.05m}{cost}\\\\cost=\frac{3.05m*1.50(dollars)}{1m}=4.575(dollars)=4.58(dollars)

Hence, we have that the cost of the fabric will be $4.58.

The correct option is: D.$4.58​

Have a nice day!

Factor completely 49m4 + 140m2 + 100
postnew [5]

Answer:

Step-by-step explanation:

Use identity : (a + b)²  =a² + 2ab + b²

49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²

                                  = (7m²)² + 2 *7m²*10 + 10²

                                   = (7m² + 10)²

                                   = (7m² + 10)(7m² + 10)
