one year ago, a man was 8 times as old as his son. Now his age is equal to the square of his son' age. Find their present ages.
Answers
8, 16, 24, 32, 40, 48, 56, 72, 80, 88, 96 are all divisible by 8.
We also know that his current age is the square of his son's age. So we can check the numbers that follow the multiples of eight to see if they'll work.
The subsequent numbers, in order, are
9, 17, 25, 33, 41, 49, 57, 73, 81, 89, 97
Now, let's list which ones are squares, meaning a number multiplied by itself is equal to anther number.
9 is the square of 3
25 is the square of 5
49 is the square of 7
81 is the square of 9
Only these four will work, but right now, ANY of these four will work. Let's use a little science to narrow it down.
It is scientifically improbable for a 9-year-old to have a 3-year-old son, so we'll rule that one out. It's also highly unlikely that an 81-year-old has a 9-year-old son, so we'll cross that off the list, as well.
This leaves a 25-year-old man with a 5-year-old son, and a 49-year-old man with a 7-year-old son, both of which are most likely.
At this point, you can choose whichever you'd like, or put down both as the answer.
The man and his son's present ages are either 25 and 5, or 49 and 7.

Then put the decimal in the same spot as the dividend (the number being divided)
divide by 9 to 6,,,, u cant divide so put a decimal [ 0. ] then put 1 back to 6 and divide 61 by 9 u get [ 6 ] and remains 7 put 0 back of 7 and do the same process
u will get 0.6777777777777777

For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!

30²-18²=x²
x²=576
x= 24 inches
30²-18²=b²
576=b²
√576=√b²
b=24
so your answer will be C 24 inches
