Answer:
24.5 kJ
Step-by-step explanation:
Kinetic energy is given by the formula ...
KE = 1/2mv² . . . . . where m = mass
The gazelle's kinetic energy is ...
KE = 1/2(40 kg)(35 m/s)² . . . . . where m is meters
= 24,500 J . . . . . . 1 J = 1 kg·m²/s²
= 24.5 kJ . . . . . . . 1000 J = 1 kJ
Answer:
1 hour = 60 minutes
20 minutes = 1/4 of 60 minutes, which means 60 minutes = 4/4
when you write ratios, the larger number goes first - 60 minutes out of 15 minutes = 4/1, so the ratio in simplest form is 4:1

Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.

Answer:
A = 140° B = 30° C = 10°
Step-by-step explanation:
3x + 135 = 180
3x = 45
x = 15°
2 X 15 = 30
1 X 15 - 5 = 10
