The longest blue whale on record was about 18 scuba divers in length. use breaking apart to estimate the length of the blue whale. explain how to estimate the length of the whale using compensation

Length of the blue whale estimation: 108 ft

Step-by-step explanation:

Assuming that each scuba diver is 6 ft long, then the length of the blue whale is: 18 x 6 ft

This multiplication can be done using compensation as follows:

first, substitute 18 by 20:  20 x 6 = 120

then, adjust subtracting 6 groups of 2, or 12: 120 - 12 = 108

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

any options?
