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:
good luck!
Step-by-step explanation:
Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
Answer:
its 420
Step-by-step explanation:
420+69+69=420
Answer:
area is 630
we can multiply 2 1 by 21= 63 by 10=630
