Paul, colin and brian are waiters. One night the restaurant earns tips totalling £77. 40. They share the tips in the ratio 2:3:4
EleoNora [17]

Answer:

$17.20

Explanation:

To easily get the ratio figured out between Paul, Colin and Brian, try seeing how much the ratio adds up to. With 2:3:4, there is a total of 9; so take 1/9th of 77.40 to get $8.60

You can convert these ratios to fractions, with Paul getting 2/9ths, Colin getting 3/9ths and Brian getting 4/9ths

As Brian is effectively getting double the amount of money, you can just take the amount Paul is getting in tips and use that as the reference for how much Brian is earning which is $8.60 x 2 or in this case, $17.20

How can scientists ensure that their results are reliable? check all that apply. by making multiple observations by repeating tr
Neko [114]

The scientists ensure that their results are reliable by repeating trials.

Given that scientists ensure that their results are reliable.

We are required to tell the way how scientists ensure that their results are reliable.

Reliability is basically defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, or will operate in a defined environment without failure.

Reliability increases from repeating trials.It is like vaccines. Firstly the trials to be made on small number of persons, then the numbers increases and then ultimately the trials are done on the large number of persons.

Hence the scientists ensure that their results are reliable by repeating trials.

Identify the oxidation numbers for all the elements in the reactants and products for 2mno4−(aq)+3s2−(aq)+4h2o(l)→3s(s)+2mno2(s)
Sidana [21]

The oxidation number if eah of the elements is as follows;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

<h3>What is a redox reaction?</h3>

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.

Let us now consider the oxidation  number of each element from left to right;

  • Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
  • Oxidation number if hydrogen is +1 on both sides
  • The oxidation number of oxygen is -2 on both sides
  • The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
