12v + 3b = 243
4v + 4b = 204....multiply by -3
-------------------
12v + 3b = 243
-12v - 12b = - 612 (result of multiplying by -3)
-------------------add
-9b = - 369
b = -369/-9
b = 41 <=== each bus holds 41 students
4v + 4b = 204
4v + 4(41) = 204
4v + 164 = 204
4v = 204 - 164
4v = 40
v = 40/4
v = 10 <== each van holds 10 students
Radians are in pi format
360 degrees=2pi radians
x/360=y/2pi
x/180=y/pi
if we wanted to convert from radians to degrees then
if we had x radians then
=degrees
so pi/9 radians is
20 degrees is pi/9 radians
the other one is easy as well
-5pi/12
-75 degrees or 360-75=285 degrees
Answer:
There would be 7 groups of students because 56 divided by 8 students gives you 7 groups.
Step-by-step explanation:
9514 1404 393
Answer:
smaller : larger = 3 : 4
Step-by-step explanation:
The scale factor is the ratio of corresponding dimensions. If we use the width dimensions, we have ...
smaller/larger = 9/12 = 3/4
The scale factor is 3/4.
