Answer:
the last choice
Step-by-step explanation:
consists of a sloping surface connecting a lower elevation to a higher elevation
If the height was 10, then the volume of the cube would be 1000 because you find volume you must multiply the length*width*height and the value of those three is 10.
Now since volume is 1000 and the volume of a 2in cube is 8 (again, lwh=V) you can divide 1000 by 8 and you would get 125. So that means 125 2in cubes can fit inside the bigger cube.
If the volume of this cube were 750in^3 and you had to find the height, you would use the Volume formula again:
l*w*h=V
10*10*h=750
20h=750
((divide both sides of the equation by 20 to find the value of h))
h=37.5
If the surface area of the cube were 680in^2 then you would use the surface area formula to find the value of h:
(2(lw))+(2(lh))+(2(wh))=A
(2(10*10))+(2(10h))+(2(10h))=680
200+20h+20h=680
subtract 200 from both sides of the equation:
40h=480
divide both sides by 40 to get the value of h:
h=12
Answer:
Weber's Law
Step-by-step explanation:
- Weber's law States that it is a mathematical model of the difference threshold stating that the magnitude needed to detect a physical change in a stimulus is proportional to the absolute magnitude of that stimulus. Thus, the more intense the stimulus, the greater the change that must be made in it to be noticed.
Answer:
Length of the rectangle = 16 inches
Width of the rectangle = 12 inches
Step-by-step explanation:
Let the length of the rectangle be represented by x.
Then width can be expressed as
Perimeter of a rectangle is the sum of four sides of the rectangle.
This can be expressed as 2*(length + breadth)
=
=
=
But perimeter is given as 56.
So,
=>
=>
Hence length of the rectangle = 16 inches
Width of the rectangle = = 12 inches
The first thing you should know is that this is an equation of the form:
y (t) = Asen (wt)
Where,
w: angular speed
By definition,
w = 2 * pi * f
Where,
f: frequency
Substituting values:
3520 * pi = 2 * pi * f
Clearing f:
f = (3520 * pi) / (2 * pi)
f = 1760 hz
Answer:
f = 1760 hz
