Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4

sukhopar [10]

Answer:

An adult male Komodo dragon is $10\frac12$ feet.

Therefore the male is $1\frac34$ feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is $1\frac34$ feet long.

It's mother is $8\frac34$ feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6× $1\frac34$ ) feet

$=6\times \frac74$ feet

$=\frac61\times \frac74$ feet

= $\frac {21}2$ feet.

$=10\frac12$ feet.

$\therefore 10\frac 12- 8\frac34$

$=\frac{21}{2}-\frac{35}4$

$=\frac{21\times 2-35\times 1}{4}$

$=\frac{42-35}{4}$

$=\frac74$

$=1\frac34$

Therefore the male is $1\frac34$ feet longer than the mother.

What is the slope of a line that contains the points (2,2) and (4,4)

Gre4nikov [31]

Answer:

m = 1

Step-by-step explanation:

Slope is defined as m = rise / run.

As we move from (2,2) to (4,4), x increases by 2 and y increases by 2.

Thus, the slope of this line is m = rise / run = 2/2 = 1: m = 1

median is putting the numbers in a line ex.( 2, 6, 4, 5, 3) and crossing out left to right until theres one number left

mode is which ever number is repeated the most
