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:
4
Step-by-step explanation:
First of all we will define rotational symmetry.
Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.
The order of rotational symmetry is how many times it matches the original shape during the rotation.
So for the given shape, we can observe that the shape has four same type of sides. The shape in rotation will be like original shape 4 times in a complete rotation. So the order of symmetry is 4 ..
Answer:
RS = 17
Step-by-step explanation:
Given S lies on RT , then
RS + ST = RT , that is
RS + 3 = 20 ( subtract 3 from both sides )
RS = 17
