Answer: 1 1/4feet
Step-by-step explanation:
From the question, we are informed that the depth of the water in the pool changes by −3/4 foot every hour and that the depth of the water was 5 feet when she started draining.
The depth of the water after 5 hours will be:
= 5 - 3/4(5)
= 5 - 15/4
= 5 - 3 3/4
= 1 1/4 feet

Answer:
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
Total cost = $10,320
Step-by-step explanation:
Let n and p represent the vectors for number of products and prices respectively.
Also, the coordinates i,j and k represent cashews, walnut and Brazil nut respectively.
The vector form of the total number of bags ordered and the cost are;
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
We can obtain the total cost by obtaining the dot product of the two vectors.
Total cost = n.p = (120i + 310j + 60k).(29i + 18j + 21 k)
C = 120×29 + 310×18 + 60×21
C = $10,320

it's equivalent to 1/2
Answer:
Option B.
Step-by-step explanation:
It is given that,
Thickness of Each DVD case = 14 mm
Thickness of each layer of padding = 10 mm
Length of the interior of the box = 132 mm
Let d represents the number of DVDs that the distributor can fit into one box with two layers of padding.
Thickness of d DVD cases = 14d mm
Thickness of two layers of padding = 10×2=20 mm
Total thickness of d DVD cases and 2 layers of padding = 14d+20
Total thickness must be less than or equal to 132.
Therefore, the correct option is B.
