24 cubes, each 8 cubic inches, meaning each 2 inches on a side. So the dimensions must be even to fit cubes exactly. Our box with 9 inches is really only effectively 8 inches because that extra inch doesn't help us fit another cube.
So our total volume:
inches minimum
Answer:
4.08 km
Step-by-step explanation:
we must know what is the speed of sound to determine the distance at which the ray originated
The speed at which the sound of lightning travels is approximately 0.340km/s
then
d = 0.340km/s*12 s= 4.08 km

2x3=6 20x30=60
60x3.26578271926=19882.887297219
Answer:
1. DB = 10 as diagonals of isosceles trapezoid are congruent
2. ∠DAB and ∠BCD are supplementary angles
- m∠BCD = 180° - 120° = 60°
3. ∠BCD is congruent with ∠ADC as trapezoid is isosceles
4. AB = 15, DC = 25,
- EB = 1/2(AB + DC) as midline
- EB = 1/2(15 + 25) = 20
5. m∠ADC = 2x - 10, m∠ABC = 3x + 40
<u>These are supplementary, find x first:</u>
- 2x - 10 + 3x + 40 = 180
- 5x + 30 = 180
- 5x = 150
- x = 30
- m∠BCD = m∠ADC = 2*30 - 10 = 50°
