Answer:
2 kg.
Step-by-step explanation:
F = m * a (Newton's Second Law of Motion).
10 = m * 5
The mass m = 10/5 = 2 kg.
Answer:
divide 1.5x10^-10 by 2.5x10^-11 which is 6 meaning the Mercury atom is 6 times larger than a hydrogen atom.
Step-by-step explanation:
im sure thats right !
The correct factorization is
2(x-2)²
1 gallon = 16 cups
1 hour = 60 min
16 cups = 60 min
5 gallons =180 min/ 3 hrs
1 cup = 3.75 minutes
◆ Define the variables:
Let the calorie content of Candy A = a
and the calorie content of Candy B = b
◆ Form the equations:
One bar of candy A and two bars of candy B have 774 calories. Thus:
a + 2b = 774
Two bars of candy A and one bar of candy B contains 786 calories
2a + b = 786
◆ Solve the equations:
From first equation,
a + 2b = 774
=> a = 774 - 2b
Put a in second equation
2×(774-2b) + b = 786
=> 2×774 - 2×2b + b = 786
=> 1548 - 4b + b = 786
=> -3b = 786 - 1548
=> -3b = -762
=> b = -762/(-3) = 254 calorie
◆ Find caloric content:
Caloric content of candy B = 254 calorie
Caloric content of candy A = a = 774 - 2b = 774 - 2×254 = 774 - 508 = 266 calorie
