The successor of a certain number when added to twice the number produces 61. What is the number?

1 answer:

3 0

Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61

The cone and cylinder above have the same radius, r, and height, h. The volume of the cone is 69 cubic centimeters. What is the

MatroZZZ [7]

Answer:

207 cubic centimeters

Step-by-step explanation:

Given

volume of cone = 9 cubic centimeters

Since the cone and cylinder above have the same radius, r, and height, h, then r = h

volume of the cone = 1/3πr²h

69 = 1/3πr²h

πr²h = 69*3

πr²h = 207cubic cm

Since the volume of the cylinder = πr²h

Hence volume of the cylinder is 207 cubic centimeters

Gelneren [198K]

Answer:

161 is your answer.

Step-by-step explanation:

Easy! If Kiersten has 23 balloons and Catherine has 8 times more than Kiersten, all we need to do is multiply. 23x8=184. Now to figure out how many more red balloons Catherine has compared to Kiersten we need to subtract Kiersten's amount from Catherine's amount. 184-23=161. So Catherine has 161 more red balloons than Kiersten.
