Answer:
There were 3 cars and 9 buses used for the field trip.
Step-by-step explanation:
Let the number of cars be x
and Number of buses be y.
Total number of vehicles used = 9
Hence,
Also
Each Car carries students = 4
Each Bus carries students = 35
Total Students = 222
Hence,
Now multiplying equation 1 by 4 we get;
Now Subtracting equation 3 from equation 2 we get;
-(4x+4y) =222-36\\4x+35y-4x-4y=186\\31y = 186\\y = \frac{186}{31} = 6](https://tex.z-dn.net/?f=4%28x%2By%29%3D%204%5Ctimes%209%20%5C%5C%5Btex%5D%284x%2B35y%29-%284x%2B4y%29%20%3D222-36%5C%5C4x%2B35y-4x-4y%3D186%5C%5C31y%20%3D%20186%5C%5Cy%20%3D%20%5Cfrac%7B186%7D%7B31%7D%20%3D%206)
Now y = 6
∴ x + y = 9 (Given)
x + 6 = 9
x = 9 - 6
x = 3
Hence, There were 3 cars and 9 buses used for the field trip.

Answer:
Step-by-step explanation:
<u>Ball dropped and we start count from that moment:</u>
- 160 ft down
- 80 ft up and down
- 40 ft up and down
- 20 ft up and down, end
<u>Total distance:</u>
- 160 + 80*2 + 40*2 + 20*2 = 440 ft
Answer:
If 50.24cm = Circumference
Radius = 8cm
If 50.24cm^2 = Area
Radius = 4cm
Step-by-step explanation:
50.24cm what? Circumference? Area?
π = 3.14
2πr = Circumference
50.24 / 2π = r
r = 8
πr^2 = Area
50.24 / π = r^2
r^2 = 16
r = 4
Mother is 36
and she is 6 year older than raju 3 times
N is rajiu age
N = 36÷ ( 6 x 3)
= 36 ÷ (18)
N = 2
Raju is 2 years old
