First you need to know that a dozen is 12.
Next, you need to make that into a fraction by putting it over 1: 12/1
Then, you multiply that by your first fraction: 3/4 x 12/1 = 36/4
Finally, simplify 36/4 = 9
Raymond bought 9 rolls.
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
Answer:
C
Step-by-step explanation:
5a + 18 < -27
5a < -45
a < -9
Graph C matches the solution set of this inequality.
247.62 x 0.15 = 37.143
round to $37.14
