Answer:
Look below! Branliest please!
Step-by-step explanation:
To find the volume, we multiply 12 by the height and then by 3.14. So for 1, we get 1*12 which equals 12, then we multiply that by 3.14 and we get 37.68. So we do that for all of them.
1*12*3.14 = 37.68
3*12*3.14 = 113.04
5*12*3.14 = 118.4
7*12*3.14 = 263.76
Answer:
y = 8
Step-by-step explanation:
11y + 4y + 60 = 180
11y + 4y = 120
15y = 120
y = 8
Answer:
Each algebra book costs $60.
Step-by-step explanation:
A=bill for algebra books; S=bill for science books=A+$360
S+A=$3960 Substitute for S
A+$360+A=$3960 Subtract $360 from each side.
2A=$3600 Divide each side by 2.
A=$1800 The order for 30 algebra books cost $1800.
Individual book=A/30
individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.
Parallel: line p with slope 2/5
Perpendicular: line n with slope -5/2
the other two would be neither.
