The correct answer for the question that is being presented above is this one:
We need to express the ksp expression of C2D3
<span>C2D3
= (2x)2(3x)3
= 108x5 </span>
<span>Then set that equation equal to your solubility constant </span>
<span>9.14x10-9 = 108x5 </span>
<span>x = 9.67x10-3
</span>
<span>So the molar solubility is 9.67x10-3</span>
Answer:
it is 5 feet squared
Step-by-step explanation:
multiply them all
.022 would be 22 hundredths as a decimal
Answer:
180ft.²
Step-by-step explanation:
If the area he paces divided by the area his apprentice paces equals three, then we can write ;
J/a = 3
In ratio form,. J : a = 3 : 1
Where J. represent John.
and. a represent the apprentice
Hence,
the area john will pace
= ( 3/4) × 280 ft.² = 180 ft.²
Answer:
4) 12 different calzones
5) 15 ways
6) 8 outfits
Step-by-step explanation:
When counting the total number of combinations like these situations, multiply the number of choices of each type together
For 4: 3 sizes, times 4 fillings, is 12 different calzones
For a small calzone, there are 4 diffferent fillings to choose from, making 4 calzones,
For a medium calzone, there are 4 differnt fillings, making 4 more for a total of 8,
For a large calzone, there are 4 different fillings, making 4 more for a total of 12
The same logic applies to the other problems
