Answers

Answer 1
Answer:

Answer:

240 sweets total

Step-by-step explanation:

We know the ratio Adrian:Ben:Charlie=7:4:9. We can put one sweet as x:

  • 7x+4x+9x=20x
  • Charlie has 24 more sweets that Adrian– 9x-7x=2x=24
  • So– x=12
  • Now– 7(12)+4(12)+9(12)=20(12)=240

Check your work:

  • 84:48:108
  • 108-84=24
  • 84+48+108=240

A quarter has a diameter of 2.4 m . what is it's circumference in cm

Answers

First lets convert the diameter to cm,
2.4 m equals 240 cm, that is by multiplying 2.4 times 100 because 1 meter has 100 cm
then we need to know how to calculate the circumference, and that is by multiplying pi (3.14) times the diameter of the circumference, that is:
circumference = pi*diameter = 3.14*240
circumference = 753.6 cm
that is the solution

Its irrational because the square root of 127 is a decimal that goes on and on and cannot be represented as a fraction. So it is irrational.
