Answer:
Phải
Step-by-step explanation:
D) every hour, the number of litera decreases by 0.25 liter
So time = distance/speed
515/216 = 2.38 min
in mixed number , 2 whole 83/216 !
Answer:
The players ran 150 meters
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
Since we have a rectangle with sides 90 and 120, we know if we split a diagonal across it, we will get a right triangle with legs 90 and 120. From there, we use Pythagorean Theorem to solve:
90² + 120² = c²
8100 + 14400 = c²
c² = 22500
√c² = √22500
c = 150
Answer:
Volume = 0.1696 L
The formula is Area of base of refraction cup × Depth of the refraction cup
Step-by-step explanation:
The dimensions of a refraction cup are;
Diameter = 120 mm
Depth = 30 mm
Therefore, volume of the refraction cup = Area of base × Depth
Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³
1 L = 1000000 mm³
Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L
The formula is Area of base of refraction cup × Depth of the refraction cup.
