Kinetic Energy = (1/2)mv².

where m = mass in kg= 2.5 * 10⁵kg = 250000 kg, v = velocity in m/s = 3*10² m/s = 300 m/s

Kinetic Energy = (1/2)*250000*300² = 0.5 * 250000 * 300 * 300

                         = 1.125 × 10¹⁰  Joules.

Pls help I don’t get what dis teacher even wants bro
Kaylis [27]

Answer:

5 cups of flour.

Step-by-step explanation:

I know the wording of the problem may be confusing at first, but if you look at it a little bit, it's just multiplication and division.

To start,

12 biscuits require 2 cups of flour,

meaning that 6 biscuits (half of the original) only require 1 cup.

<u>(12/2 = 6)</u>

Next,

We need to find how much flour is in 30 biscuits.

We know that 1 cup is in 6 biscuits, and if you were to find how much was in 30 biscuits, you would just need to divide 30 by 6.

<u>(30/6 = 5)</u>

5 cups of flour would be your answer.

To put it mathematically,

(12/2 = 6), (30/6 = 5)
