Sophia's school took a field trip. a total of 21 vehicles were needed for the trip. some students took the bus, and some student
Liono4ka [1.6K]
Let x be the number of buses, and y the number of cars.
\left \{ {{x+y=21} \atop {30x+4y=318}} \right.
We can solve for y in the first equation to get:
y=21-x
Now we can replace 21-x in our second equation, and solve for x:
30x+4(21-x)=318
30x+84-4x=318
26x=234
x= \frac{234}{26}
x=9

We can conclude that 9 buses were needed for the trip.

Alex17521 [72]

Answer:

The diameter is 14π

Step-by-step explanation:

let 49π=πr^2

Cancel the π's, and you get 49=r^2

Take the square root and you get r=7

The diameter of a circle is 2πr.

2π(7)=14π.
