Bill measures the circumference of a circular fish pond to be 28 ft. What is the diameter of of the fish pond, rounded to the nearest foot? Use 3.14 to approximate pi.
Answers
C=pid C=28 pi=3.14 28=3.14d divide both sides by 3.14 8.9=d round 9=d answer is 9ft
you would divide 28 by 3.14 since the equation is 2pi R so the diameter would be 8.92
3. Ron used 24 cubes to make this 3-step staircase. If he uses a total of 84 cubes to make a similar staircase, how many steps will the staircase have?
Answers
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
28 steps because 84 divided by 3 equals 28
Pls explain how to solve this 15-3n=n-1
Answers
First you have to isolate the variable. That means you have to get all the terms with the letter (n) on one side of the equal sign and everything else on the other side. To do this: First add 3n to both sides and get: 15=4n-1 Now you have to add 1 to both side and get: 16=4n Now you have to divide both sides by 4. You get the answer of: 4=n
