Match the three dimensional figure to its volume based on the given dimensions assume n= 3,14.
stepan [7]

Answer:

Volume of right cylinder= 150.72 cu cm

Volume of cone= 314.159 cu cm

Volume of pyramid with base area 16= 160 cu cm

Volume of pyramid with length 3 =48 cu cm

Step-by-step explanation:

Volume of right cylinder = πr²h= 22/7 (4)²3=  150.72 cu cm

Volume of a cone = 1/3 πr²h= 1/3 (22/7) (5)²(12)= 314.159 cu cm

Volume of a pyramid = 1/3 ah= 1/3(16) (30)= 160 cu cm  (where a= area and h= height)

Volume of pyramid= 1/3 (3*3)(16)= 48 cu cm

How to solve 6x + y= -5, -6x + 12y=96 using elimination and does it have no solution or many solutions?
Alika [10]

Answer:

x = -2

Step-by-step explanation:

Arrange 6x + y= -5, -6x + 12y=96 vertically:

6x + y= -5

-6x + 12y=96       Now combine like terms:

--------------------

       13y = 91

Solving for y by dividing both sides by 13:  y = 7

Find x by substituting 7 for y in the second equation:  -6x + 12(7) = 96

Then -6x = -84 + 96, or:

-6x = 12, and so x = -2

Find the annual percentage rate of change for the population of Oregon. In 2000, there were 4.8
MrRa [10]

Answer:

The annual percentage rate of change for the population of Oregon is of 8.125%.

Step-by-step explanation:

Total percentage change:

Change multiplied by 100 and divided by the initial value.

Change: 8.7 - 4.8 = 3.9 million

Initial value: 4.8

Percentage change: 3.9*100/4.8 = 81.25%

Annual percentage rate of change

81.25% during 10 years(from 2000 to 2010).

So, per year

81.25%/10 = 8.125%

The annual percentage rate of change for the population of Oregon is of 8.125%.
