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
Answer:Hope this helps :D
Explanation:
Cu = 27, S = 16 and O = 25.92
relative formula mass = 27 + 16 + (5.4x4.8) = 286.216
only one aluminum atom of relative atomic mass
64 % Cu = 100 x 64 / 160
x = 1036.8
Classifying each label into the correct category of human red blood cell
A) Human red blood cell shrinks
- Cells placed in hypertonic solution
- More water moves out of cell
B) Normal Human red blood cell
- Cell placed in isotonic solution
- Water enters and leaves at the same rate
C) Human red blood cell swells
- Cell placed in hypotonic solution
- More water moves into cell
<h3>Types of solution</h3>
A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.
Hence we can conclude that the classification of each label into the appropriate category are as listed above.
