Step-by-step explanation:
Given
mass (m) = 5000 kg
velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s
Now
Kinetic energy
= 1/2 mv²
= 1/2 * 5000 * 27.78²
= 1929321 joule
You have to divide the numbers that do not have the variable y in it.
Answer:
Step-by-step explanation:
Sum of the angles of a triangle is ALWAYS 180°.
2x+3x+5x = 180°
10x = 180°
x = 18°
2x = 36°
3x = 54°
5x = 90°
The angles are 36°, 54°, and 90°
Problems are very often written in a confusing way. This one couldn't possibly have been
written any more clearly. Sooner or later, you have to stop telling yourself that you have
no clue, settle down, and carefully read the words that are right there on the page.
I'll tell you one more detail that's not in the problem: "breadth" means "width".
Now. The problem clearly tells you all of these things, in this exact order:
=> Area of the walls = (2 x height) x (length + width)
=> length = 8m
=> width = 6m
=> height = 2.5m
Is there a reason you can't take the numbers for length, width, and height,
and write them in the formula for the area ? Do I have to do all the work ?
Area = (2 x height) x (length + width)
Area = (2 x 2.5m ) x ( 8m + 6m )
Do the arithmetic inside the parentheses:
Area = ( 5m ) x ( 14m )
Do the multiplication:
Area = <u>70 m² .</u>
You will never see a problem that comes any closer to answering itself <em>for </em>you.
