Using proportions, the correct representation of that time period is of 4.47 minutes.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

We have that one minute has 60 seconds, hence the proportion that the 28 seconds correspond of a minute is:

28/60 = 0.47 min.

Hence the correct representation of that time period is of 4.47 minutes.

In a school of 2000 students, 1150 do not like puzzles. 2/5 of the students travel to school by bus. 595 of the people that do l
Vadim26 [7]

The number of students who do not like puzzles and ride the bus to school is 205

To find the answer it is necessary to do the following procedure:

To find out how many people the 2/5 traveling by bus are equivalent to, divide the total number (2000) of people by 5, and then multiply that value by 2.

  • 2000 ÷ 5 = 400
  • 400 × 2 = 800

From the above, it can be established that 800 people travel by bus to school. Now, to know how many people travel by bus and do not like puzzles, the following operation must be done.

Subtract the number of students who do like puzzles and ride the bus (595) from the total number of students who ride the bus (800)

  • 800 - 595 = 205

So the answer is 205 students ride the bus and they don't like puzzles.

The sum of three numbers is 50. One number is five more than a second number. It is also twice the third. Find the numbers.
Blababa [14]
Let
One Number = x
Second Number =x-10
Third Number=x/2

Sum of three numbers is 50
x+x-10+x/2=50
2x-10+x/2=50
Multiply by 2 both sides
2*(2x-10+x/2)=50*2

4x-20+x=100
5x=100+20
5x=120
x=120/5
x=24

One number = x=24
Second number =x-10=24-10=14
Third number= x/2=24/2= 12
