Answer:
cosine 71° = distance from wall / 10
A) distance from wall = cosine (71) *10
distance from wall = 3.2557 feet
B) Height up the wall ^2 = 10^2 - 3.2557^2
Height up the wall ^2 = 100 -10.59958
Height up the wall ^2 = 89.40041751
Height up the wall = 9.45518 feet

Step-by-step explanation:
Let x liters represent 70% of the solution.
Let us assume that solution is diluted with water, which has a 0% strength.
We have been given that you have been asked by the Pharmacist to prepare 3 liters of a 30% strength solution. Your pharmacy stocks the active ingredient in 8 oz bottles of 70% strength.
The amount of water would be 3 liters minus liters of 70% solution that is .
Now we can set an equation where 70% of x plus 0% of is equal to 30% of 3 liters.
Since our amount is in liters, so we need to convert 1.2857 liters into oz.
1 liter = 33.814 oz
1.2857 liters = 1.2857*33.814 oz = 43.4746598 oz
Since each bottle contains 0 oz, so we will divide 43.4746598 by 8 to find the number of bottles.
Since we cannot open 0.43433 of a bottle, so we need to open 6 bottles and option C is the correct choice.
