Answer:
y=25x-500
Step-by-step explanation:
25 is positive with the x because its the slope and 500 is the cost so you subtract is. 500 is the y intercept
Answer:
16.3
Step-by-step explanation:
-(-3.5) + (-(-12.8))
3.5+12.8= 16.3
Answer:
d^2 = 30^2 + 12^2
e^2 = d^2 + 8^2
e^2 = 30^2 + 12^2 + 8^2
e = √(30^2 + 12^2 + 8^2) = 33.3 ft
Explanation
The question requires that we figure out the sides that represent the top/bottom faces and the left/right faces.
We are given the plan of the aluminum sheet
The top, bottom, left and right faces are shown below
The dimension for the top and bottom is
Since they are two
Therefore the total area for the top and bottom will be
For the left and right faces, the dimensions are
The dimensions of the left and right faces will be
Since they are two, then
The area will be
Answer:
2300 liters of water.
Step-by-step explanation:
The volume of the barrel is 4.6 m^3, and we know that this is half--filled with water.
Then the total volume of water inside the barrel is:
(4.6 m^3)/2 = 2.3 m^3
So we have 2.3 m^3 of water, and we want to write this in liters.
We know that 1 liter = 0.001 m^3
then:
1 = (1 L)/(0.001 m^3)
Now we can rewrite:
2.3 m^3 = (2.3 m^3)*1 = (2.3 m^3)* (1 L)/(0.001 m^3) = (2.3 m^3/0.001 m^3)* 1L
2.3 m^3 = 2300 L
So we have 2300 liters of water in the barrel.
