Answer:
A
Step-by-step explanation:
By doing the unit rate, dividing 19 on both the top and bottom, getting this 8.36.../1, you can just round it to 8/1, meaning he makes about 8 deliveries per hour. Hope this helps!
First calculate volume of the cylindrical container: Pi * R2 * H; where Pi is 22/7 or 3.147, R is the radius and H is the height of the container.
Vol of the cylindrical container: 3.147 * (3.25/2) * (3.25/2)* 5 = 41.55 inch 3
Volume of the shaker using the above principle:
3.147 * (1/2) * (1/2) * 1.5 = 1.18 inch 3
Number of times it can fill the salt shaker will be the ratio of the volumes:
= Volume of the cylindrical container divided by the volume of the shaker = 41.55 divided by 1.18
Answer is 35 times if rounded in absolute number.
