To do this task the best way is always add both "sides" of ratio and divide whole group by this sum.sum=4+7=1133:11=3Now we know how much is 1 and we can multiply by 4 and by 7 to find the answer.3*4=12 - first group3*7=21 - second group
Your result is ok.
Answer:
As the first part comes to the rest means, then it will fall under gravity directly.
First of all maximum height,
H=
g
u²sin²θ
H=
2×10
400×(

)
H=10m.
As initially the full projectile was supposed to land at A but due to explosion first part land at A', so to make the centre of mass lies at A the second part should lie at B.
f they don't break (explode) range OA
OA=
g
u²sin2θ
OA=400×sin45×

Answer:
24.997
Step-by-step explanation:
Let's start with the easy parts of the perimeter...the flat parts...7 + 7 = 14. We'll add that to the arch shortly.
We need to find the circumference of the whole circle, then divide by 4 to get 1/4 of a circle. (There might be a faster way, but this gets the job done.)
circumference = (2)(pi)(r)
= 2(3.142)(7) = 43.988
Now divide that by 4 for the distance of the arch.
43.988/4 = 10.997
Add that to the flat parts
10.997 + 14 = 24.997

Answer:
Step-by-step explanation:
In both the point, y-coordinates are same. So, the line is parallel to x-axis
Slope of the line parallel to x-axis =0
m = 0
Equation : y =6.7
