Answer:
KE = 900,000t²
Step-by-step explanation:
The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;
m is the mass of the sport car = 2000kg
v is the velocity of the car
Since v = at
v = 30t
Substituting the given values into the KE formula;
KE 1/2 * 2000 * (30t)²
KE = 1000*900t²
KE = 900,000t² Joules where t is the time measured in seconds
Answer:
70 billion bacteria
Step-by-step explanation:
I. Given 1 oz = 28 g, 1g contains 2.5 billioin bacteria, find bateria in 1 oz by
If 1 oz = 28g and 1 g = 2.5 billion bacteria
1 = 2.5 billion
28* 1 = 2.5 *28 billion
28g = 70 billion
That makes 70 million bacteria per 1 oz.
Hope that help :)
3x-4y= 6
3x÷3-4y=6÷3
x-x-4y=2-x
4y÷4=2-x/4
y= 2-x/4
First let's review the area formula for a circle.
Area=π
Now that we know the radius, r is 10. The area is
10*10*π=100π
I will approximate π to 3.14 although you could do it more precise or less precise. The final answer will be 100*3.14=314 squared centimeter.
