I just need the advance ticket price iknow that the same day is 15$
OverLord2011 [107]
I would feel better if you'd explain how you "know" that a "same-day" ticket is $15.  

"<span>The combined cost of one advance ticket and one same-day ticket is $35."  This would imply that the cost of one advance ticket is $(35-15), or $10.  

Check by substitution to determine whether $15 and $10 are correct.  If not, please show your work, so that someone else or I could step back in and help.

Brrunno [24]

Answer:  Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

A=l\times w, where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2  \text{Rounded to the nearest tenth}

Therefore, the area of rectangle =13.6\text{ cm}^2
