Answer: 35 seventh graders
Step-by-step explanation:
The simplified ratio is 4:7 sixth graders to seventh graders
The number of sixth-graders is 5 times the number shown in the ratio of attendees (20/4 = 5). Thus, the number of 7th graders must also be 5 times greater than the simplified ratio.
7*5 = 35, thus there are 35 seventh graders in the club
Remember slope is

. In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is
Answer:
Step-by-step explanation:
Area = pi r^2 if 3 is the radius
pi (3)^2 = 9 pi in^2
if 3 is the diameter then radius = 1.5
pi r^2 = pi (1.5)^2 in^2
