80 students voted for an eagle 160 students voted for a bulldog round to the nearest whole percent what percent of these student
Alex_Xolod [135]
First you need to find the amount of students who voted.
80 + 160 = 240
160 students out of 240 students who voted, voted for a bulldog. To find the percentage, you need to divide 160 by 240.
160/240 = .6 repeated
You need to move the decimal over two spaces to get the percentage. So then you have 66.6666%. Since it says to round to the nearest whole percent, you need to round the number right after the decimal. 6 rounds the number before it up so you get 67.
So the amount of students that voted for a bulldog is 67%.

Answer:

  • hemisphere volume: 262 m³
  • cylinder volume: 942 m³
  • composite figure volume: 1204 m³

Step-by-step explanation:

A. The formula for the volume of a hemisphere is ...

  V = (2/3)πr³

For a radius of 5 m, the volume is ...

  V = (2/3)π(5 m)³ = 250π/3 m³ ≈ 261.799 m³

__

B. The formula for the volume of a cylinder is ...

  V = πr²h

For a radius of 5 m and a height of 12 m, the volume is ...

  V = π(5 m)²(12 m) = 300π m³ ≈ 942.478 m³

__

C. Then the total volume is ...

  V = hemisphere volume + cylinder volume

  V = 261.799 m³ +942.478 m³ = 1204.277 m³

__

Rounded to the nearest integer, the volumes are ...

  • hemisphere volume: 262 m³
  • cylinder volume: 942 m³
  • composite figure volume: 1204 m³

_____

As a rule, you only want to round the final answers. Here, the numbers are such that rounding the intermediate values still gives the correct final answer. That is not always the case.
