Answer:
okay so to figure out a perfect square a number has to be outlined by itself. 8 is not. 4 is because 2 times itself is 4. 81 is because 9 time itself is 81. 44 is not. 49 is because 7 times itself is 49. 125 is not. 150 is not. 144 is because 12 times itself is 144.
To do this, multiply 9 by 18. This will show you how much they all weigh if there are 18 and each is 9 pounds.
The answer is 162.
Hope this helps!
You can treat ratios as fractions
x:13=48:104
x/13=48/104
simplify 48/104
48/104=24/52=12/26=6/13
x/13=6/13
multiply both sides by 13
x=6
the missing number is 6

Step-by-step explanation:
Answer:
The mean weight of the cats is 11.42 (rounded)
Step-by-step explanation:
To find the mean, you add up all the weights (12, 12, 9, 9, 11, 11, 16) and then divided the sum (80) of the weights by the number of cats (7)
12+12+9+9+11+11+16= 80
80 ÷ 7= 11.42857143 (I rounded my answer to 11.42)
I hope this was helpful. Have a wonderfull rest of your day!
