Answer:
79.3 m³
Step-by-step explanation:
2800 ft³ = 2800 ft³ × ((0.3048 m)/(1 ft))³ ≈ 79.3 m³
__
The conversion factor for feet to meters is 0.3048 m = 1 ft. You need the cube of that to get to cubic meters from cubic feet.
Answer:
C) (x + 5)² = 40
Step-by-step explanation:
Given the quadratic equation, x² + 10x = 15:
To complete the square, take the coefficient of the middle term (b), and divide it by 2<em>a</em>:
x² + 10x + = 15 +
x² + 10x + = 15 +
x² + 10x + 5² = 15 + 5²
x² + 10x + 25 = 40
The trinomial on the left-hand side of the equation provides a perfect square binomial factors: <em>u</em>² + 2<em>uv</em> + v² = (<em>u</em> + <em>v</em>)²
x² + 10x + 25 = 40
(x + 5)² = 40
Therefore, the correct answer is Option C) (x + 5)² = 40
Using fractions, it is found that of a wheel still needs to be painted.
- On the first wheel, 4 of the 9 equal parts have been painted, that is, of the wheel has been painted, hence has not been painted.
- On the second wheel, 6 of the 10 equal parts have been painted, that is, of the wheel has been painted, hence has not been painted.
The total fraction that still has to be painted is:
of a wheel still needs to be painted.
