Hi,

Rectangular prism or Cuboid has a volume that can be calculated by multiplying it's dimensions.

v = l \times w \times h
In your case...

v = 5 \times 3 \times 4  =  {60}^{3}
Answer = 60m3

Hope this helps.

A certain insect can beat its wings 120 times per second write an equation in slope intercept from that shows the relationship b
dalvyx [7]

Answer:

The relationship between flying time in seconds in the number of times the insect beats its wings:

  • y = 120x

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the rate of change or slope
  • b is the y-intercept

In our case,

Let 'x' be the flying time in seconds

Ley 'y' be the number of times the insect beats its wings

Given that a certain insect can beat its wings 120 times per second.

It indicates that the rate of change or slope = m = 120

In our case the y-intercept b = 0, as there is no initial condition mentioned here.

Now, substituting m = 120 and b = 0 in the slope-intercept form

y = mx+b

y = 120x+0

y = 120x

Therefore, the relationship between flying time in seconds in the number of times the insect beats its wings:

  • y = 120x
