Answer:
the top answer.............
180x feet^3
this is the answer because volume is lwh so 15 x 12 x x is 180x the labeled is 180x ft.^3
You have to give the problem and not just the options for me to solve

Answer:
water
Step-by-step explanation:
Comparison of numbers can be done a couple of different ways. One way is to subtract one from the other. If the difference is positive, the minuend (first number) is the larger of the two.
Another way is to divide one number by the other. If the ratio is more than 1, then the numerator is the larger number.
For numbers in scientific notation, the division is perhaps the easiest. Here, that gives you ...
![\displaystyle\frac{\text{water mass}}{\text{oxygen mass}}=\frac{2.99\times10^{-26}\text{ kg}}{2.66\times10^{-26}\text{ kg}}=\frac{2.99}{2.66}\approx 1.12](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Ctext%7Bwater%20mass%7D%7D%7B%5Ctext%7Boxygen%20mass%7D%7D%3D%5Cfrac%7B2.99%5Ctimes10%5E%7B-26%7D%5Ctext%7B%20kg%7D%7D%7B2.66%5Ctimes10%5E%7B-26%7D%5Ctext%7B%20kg%7D%7D%3D%5Cfrac%7B2.99%7D%7B2.66%7D%5Capprox%201.12)
This value is greater than 1, so the mass of a water molecule is greater.

You will note that the multipliers (10^-26 kg) cancelled because they were equal. If they are unequal, the usual rules of exponents apply.
Answer:
75
Step-by-step explanation:
Area of a triangle is <em>l </em>x <em>w </em>(length x width)
That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the <em>l </em>becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new <em>w. </em>Now we can solve for area.
<em>l </em>x <em>w </em>= A
5m x 15m = A
75m = A
I hope this helped :)
