If you would like to find the area of the base of the fountain, you can calculate this using the following steps:
1 2/3 ft * 2 2/3 ft = 5/3 * 8/3 = 40/9 = 4 4/9 square feet
The area of the base of the fountain is 4 4/9 square feet.
The answer is 7.75. Since there can not be 7.75 days, you can round that to 8 and say that it's almost 8 days. Hope this helps!
I'm guessing that you meant to type 4(x - 3). If that's the case, then you can solve this using the Distributive Property.
4(x - 3) Multiply the number on the outside of the parentheses by both of the numbers on the inside.
(4 · x) - (4 · 3)
(4x) - (12) Now, simplify by taking out the parentheses.
4x - 12

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 ...
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.
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
