Answer:
129 cubic inches
Step-by-step explanation:
lxwxh L=Length W=Width H= Height
Length times width times height gives you the volume
1. convert all numbers to inches
2. Multiply them together(order does not matter)
it's divergent, you can actually simplify this series by combining terms in pairs
The right answer for the question that is being asked and shown above is that: "D. The right tail is longer than the left." Positively skewed distribution<span> is asymmetrical and points in the positive direction. So, the tail on the right is longer than that of the left.</span>
Total = 36oz
Amount of 18% solution = x
Amount of 9% solution = 36 - x
Using the fact that (amount of solution) * (percent HCl) = amount HCl we can set up an expression for the amount HCl in a mixture of 18% and 9% solutions with a total volume of 36oz.
Amount of HCl = x*0.18 + (36 - x)*0.09
If we divide this by the amount of solution we get percent HCl, and we have a target of 10% HCl. Now we have an equation to solve,
[x*0.18 + (36 - x)*0.09]/36 = 0.1
x*0.09 + 3.24 = 3.6
.09x = 0.36
x = 4
Therefore,
4 ounces of 18% HCl solution and 32 ounces of 9% HCl solution
Check:
[(4*.18) + (.09*32)]/36 = 0.1?
0.1 = 0.1 Yes.
150*30% = $45
$150-$45 = $105
Marco still owes his brother $105
