112 m³
the solid is a rectangular pyramid with volume (V)
V = × area of base × height = × (8 × 4.2 ) × 10 = 112 m³
Answer: 1.3 seconds
Step-by-step explanation:
Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters. [1 km = 1000 m]
Speed of light = m/s = 299800000 m/s
Formula:
Let <em>t</em> be the time taken by the light to travel from the moon to the Earth.
Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.
Answer:
So Sara can fill 24 pint bottles completly with 3 gallons of juice.
Step-by-step explanation:
This question can be solved using a rule of three.
Each pint has 0.125 gallons. How many pints are 3 gallons?
1 pint - 0.125 gallons
x pints - 3 gallons
So Sara can fill 24 pint bottles completly with 3 gallons of juice.
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
