Answer:
7.5 jars
Step-by-step explanation:
There are 25 students in the art class.
Mr Jones is planning that for the project, each of the 25 students will need 0.3 jar of paint.
The amount of paint Mr Jones needs for this project is therefore the product of the number of students in the class by the amount of paint each student needs.
That is:
25 * 0.3 = 7.5 jars of paint
Mr Jones needs 7.5 jars of paint for the art project.
1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
Base area = 1/2 x 14 x 8
Base area = 56 units²

Volume = 1/3 x 56 x 17
Volume = 317 units³
Answer: 317 units³ (Answer A)
