Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.
Answer:
A=$21930.52
Step-by-step explanation:
Given data
Principal =44000
Time =5years
Rate of depreciation =13%
The expression for the depreciation is
A=P(1-r)^t
Substitute
A=44000(1-0.13)^5
A=44000(0.87)^5
A=44000*0.4984209207
A=21930.52
760. 93797 cubed feet
Step-by-step explanation:
The surface area of a cylinder is given by the formulae;
πD * h + 2πr² = SA
In this cylinder we are given the values of V and r which we can replace in the formulae to form an equation that will give us the h
We know twice the radius will give us the diameter = 4 * 2 = 8
πD * h + 2πr² = SA
π * 8 * h + 2 * π * 4² = 481
25.13274h + 100.53096 = 481
h = (481 - 100.53096) / 25.13274
h = 15.13838
The volume of a cylinder is given by the formulae;
πr²h = V
π *4²* 15.13838 = 760. 93797

To find the average add all the numbers first.
68 + 78 = 146
56 + 74 = 130 = 276
------------------------------------------------
Now divide 276 by the number of numbers there are (4)
276 ÷ 4 = 69
------------------------------------------------------------
69 is your average
