Answer: sorry sorry sorry sorry I'm doing a competition for who ever reaches 1k points
Step-by-step explanation:
it is the ratio of y change / x change.
when we look at the points with integer coordinates, we see that whenever x increases by 1 unit, y increases by 2 units.
so, the gradient is
+2/+1 = 2/1 = 2
Answer:
96
Step-by-step explanation:
(2^22-2^20) (3^24-3^22) (4^26-4^24)
=[(2^2-1)2^20][(3^3-1)3^22][(4^2-1)4^24]
=3*2^20*8*3^22*15*4^24
=2^23*3^23*4^24*15
=2^23*3^23*2^48*3*5
=2^71*3^24*5.
∵(2^22-2^20) (3^24-3^22) (4^26-4^24)=2^x × 3^y × 5^z,
∴x=71, y=24, z=1,
∴x+y+z=71+24+1=96.
Answer:
240kmh
Step-by-step explanation:
The distance that the train traveled in 30s is the difference of the total length of the tunnel and the train (2000m). This means it travels 2000m/30s. This ratio is the same as 240000/3600s or 240km/1hr.
Explanation :
What you would do is you take the area of the rectangle and subtract the area of the triangle
The area of a rectangle is Length * Width
