Answer:
8 vans
7 buses
Step-by-step explanation:
Let there be "b" buses
and "v" vans
Since 7 people is the capacity of vans, the total capacity is
7v
Also, since 25 people is the capacity of 1 bus, the total capacity is
25b
In total 231 people, so we can write our first equation as:
7v + 25b = 231
Now, we know there are 15 vehicles (bus + vans) in total, so we can write our 2nd equation as:
v + b = 15
Now, we solve for v and b. Let's solve the 2nd equation for v and substitute that into 1st and solve for b first:
v + b = 15
v = 15 - b
Now,

Hence, there are 7 buses
Since 15 vehicles in total, the number of vans is:
15 - 7 = 8 vans
So,
8 vans
7 buses

Answer:
50 seconds
Step-by-step explanation:
divided 150 by 3
<span>In the figure, all the dimensions of the cuboid
a = 4/5m side of the base
b = 1/3m second side of the base
c = h = 1/4m height solid
The volume is the product of the edge
V = abc = 4/5m * 1/3m * 1/4m = 4/60m</span>³ = 1/15m³
