Step-by-step explanation:
Its a perfect square and 27*3=81
Answer:
coefficient of the term of degree 4 in this polynomial is 3
Step-by-step explanation:
4) 2 1/4 - 1 2/3
8/4 - 5/3
24/12 - 20/12= 4/12
simplify: 1/3
5) 2.951+2.3+1.24= 6.491
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
Find the volume of the rectangular prism by solving the equation V = 20 × 20 × 16.
V = 6,400
Now all you have to do is get 3/4 of that number. For me, it's easier to multiply decimals, so I will change 3/4 into it's decimal form, .75
V = 6,400 × .75 = 4,800.
The volume of the tank is 4,800 cm³.
