Well I can see where you have the issue. This is actually a simple fraction problem. Let's begin.

Step 1: Determine the prices of the fabric, per every 10th of a meter.
Since we know that 10/10 of a meter=1 meter, divide 3.30 by 10 to get the price per 10th of a meter which is .33.

Step 2: Determine the price of the blue fabric.
Since the blue fabric requires 2.3 meters (or 23/10) we can multiply .33 by 23 and have the pricing for the blue fabric, which is 7.59.

Step 3: Determine the price of the white fabric.
Since we know that there is 3.5 meters of white fabric (or 35/10) we can multiply .33 by 35 and again have the pricing, which is 11.55.

Step 4: Determine the price of the red fabric.
Since we know that the costume requires 0.6 meters of red fabric (or 6/10) we multiply .33 by 6 and get the pricing for red, which is 1.98.

Step 5: Add these three numbers up to get the total price of the costume.
7.59+11.55+1.98=21.12

Step 6: Subtract the cost of the fabric from the total budget to see how much money Kelly has left.
40.00-21.12=18.88

Since the problem does not specify any other costs other than the fabric and accessories, the assumed amount left for accessories is C: $18.88

The projection of vector B on unit vector a is

(B•a)a

av(unit vector of v)= 1/√2(-1,1)

u•av= 1/√2 × (-5+7)= √2

(u•av)av= √2 × 1/√2(-1,1)= (-1,1)

1. Describe a situation that could be modeled by x≤50

Dimas [21]

There are many ways to answer. The x represents some number. We don't know what the number is, but we know that it must be less than or equal to 50. Put another way, the number can be anything you want as long as it doesn't go past 50. We say that 50 is the so called "ceiling" more or less.

Some examples:

* An elevator can only hold 50 people at maximum. Therefore, x can be any number smaller than 50 or 50 itself. Having 51 or over will be too much.

* You can only work 50 hours for one stretch of some 2 week period. If x is the number of hours you work, then x must be 50 or less as written by $x \le 50$ . So x could be x = 37 as it's less than 50, but x = 62 is not possible.

* For some small ride at a theme park, the seats are designed such that only people 50 inches or less can ride on them. If x is the height of a person in inches, then $x \le 50$ means something like x = 37 is possible but x = 62 is too high.
