Answer:
A = 100 B = 130 C = 150
Step-by-step explanation:
Translated into a system of equations:
A+B+C = 380
B = A+30
C = B + 20
So we find B from the last one:
B = C-20
Plug it in the second one:
C-20 = A+30
A = C-50
Plug it in the first:
C-50 + C-20 + C = 380
3C - 70 = 380
3C = 450
C=150
A = C - 50 = 150 - 50 = 100
B = C - 20 = 150 - 20 = 130

Answer:
50.80 cm^3
Step-by-step explanation:
the polyhedron is a rectangular pyramid
Volume of a rectangular pyramid = 1/3 x ( width x height x length)
1/3 ( 4 x 5 x 3) = 20 inches
we need to convert inches to cm
1 in = 2.54 cm
20 x 2.54 = 50.80 cm^3
110 minus 52 is 58 so the answer would be 58 more pitches
Answer:
If the children divide evenly onto 3 buses, there will be 11 children on each bus
Step-by-step explanation:
Add all 3 classes to ind total amount of students
Ms. Noels class has 10 students
Mr. Grubbs class has 9 students
Ms. Ackerman's class has 14 students
<u>Total Students:</u> 10 students + 9 students + 14 students
33 total students
Dividing 33 students in 3 busses is 33 / 3 which equals 11
