1. ratio to you and then your friend is 4 : 3. By guessing is the quickest choice and when I did that I finally found that you have had to multiply both by 8 to find:
your allowance : 32
your friend's allowance : 24
32 + 24 = 56
2. ratio to you and then your friend is 7 : 5. By guessin is the quickest choice and when I did I finally found that you have had to multiply both by 6 to find:
your allowance : 42
your friend's allowance : 30
42 + 30 = 72
Answer:
8 positive integers.
Step-by-step explanation:
One value of n would be 15 because 225 = 15^2.
Other values are 225 * n where 15n <= 1000 and n is a perfect square.
So n = 4 gives us 225* 4 = 900 which is a perfect square and 15*4 = 60.
n = 9 gives us 225 * 9 which is a perfect square and 15*9 = 135.
n = 16 gives us 225*16 and 15*16 = 240 , so OK.
n = 25 gives a perfect square and and 15*25 = 375 - so OK.
n = 36 gives a perfect square and 15*36 = 540 - so OK.
n = 49 gives a perfect square and 15*49 = 735 - so OK.
n = 64 gives a perfect square and 15*64 = 960 - so ok.
n = 81 gives a perfect square and 15 * 81 = 1215 so NOT ok.
Answer:9/4
Step-by-step explanation:multiply 2.25 by 100 so you get 225/100 and reduce
Answer:
x-1/2 is in fact a factor of 8x3-4x2+10x-5 so you are correct
Step-by-step explanation:
The equation can be simplified into (2x-1)(4x2+5) and 1/2 is one of the factors
