Step-by-step explanation: Multiply 3 to itself and you will get nine.
3^2
Answer:
5 days
Step-by-step explanation:
Speed = 359 miles/day
Distance = 1,462 mile
Use this formula to calculate time ( in number of days);
Time = Distance / speed
Next, plug in the numbers given into the formula to calculate time;
Time = 1462 / 359 = 4.0724
Since you are told to round off in days, you will round up 4.0724 to 5 days.
Therefore, it will take Tom 5 days to drive 1,462 miles.
Answer:
Amount of NaCl = 23.376 gram
Step-by-step explanation:
Given:
Molarity = 4M
Volume of solution = 100 ml
Find:
Amount of NaCl
Computation:
Molar mass of Na = 22.99 g/mole
Molar mass of Cl = 35.45 g/mole
Molar mass of NaCl = 22.99 + 35.45
Molar mass of NaCl = 58.44 g/mole
Molarity = [moles of solute / volume of solute(ml)]1,000
4 = [moles of solute / 100]1000
Moles of solute = 0.4
moles of solute = Mass of solute / molar mass
0.4 = Amount of NaCl / 58.44
Amount of NaCl = 23.376 gram
Side of base of square, a = 10 km.
Height of pyramid , h = 12 km.
Volume of pyramid is given by :
Surface area is given by :
Therefore, volume and surface area are 400 km³ and 340 km² respectively.
Hence, this is the required solution.
