The rule starting with five. 5 marbles in first line.
Every consecutive line has a number that is four less than twice the previous line.
marbles in second line = 2(marbles in first line) - 4
So the number of marbles in second line = 2(5) -4 = 10-4 = 6
marbles in third line = 2(marbles in second line) - 4
So the number of marbles in second line = 2(6) -4 = 12-4 = 8
marbles in fourth line = 2(marbles in third line) - 4
So the number of marbles in fourth line = 2(8) -4 = 16-4 = 12
marbles in fifth line = 2(marbles in fourth line) - 4
So the number of marbles in fifth line = 2(12) -4 = 24-4 = 20
marbles in sixth line = 2(marbles in fifth line) - 4
So the number of marbles in sixth line = 2(20) -4 = 40-4 = 36
36 marbles must be in the sixth line.
X = number of dimes
x + 2 = number of nickels
3(x + 2) = number of pennies
10x + 5(x + 2) + 3(x + 2) = 52
10x + 5x + 10 + 3x + 6 = 52
18x = 36
x = 2
x = 2 (number of dimes)
x + 2 = 4 (number of nickels)
3(x + 2) = 12 (number of pennies)
Check:
2(10) = 20 cents in dimes
4(5) = 20 cents in nickels
12(1) = 12 cents in pennies
Total = 52 cents
Answer:
9
Step-by-step explanation:
the 24 students need to collect 210
210/24 = 9 (to the nearest whole number)
The values of the radius and volume are placed in the formula to get the volume of the cylinder
