10 inches your hypotenuse is always going to be equal or bigger than the sum of the two sides
Answer:
3x - y = 0; 2x - y = -5
Step-by-step explanation:
Let x be the present age of Hans and y be the present age of Grace,
Since, in present Grace is three times as old as Hans,
⇒ y = 3x
⇒ 3x - y = 0
Now, after 5 years,
The age of Hans = x + 5,
And, the age of Grace = y + 5
Also, in 5 years Grace will be twice as old as Hans is then,
⇒ y + 5 = 2 ( x + 5 )
⇒ y + 5 = 2x + 10
⇒ 2x - y = -5
Hence, the required system of linear equations is,
3x - y = 0; 2x - y = -5
Answer:
none of the above
Step-by-step explanation:
cohen's d= (Mean of population - mean of sample)/ standard deviation of population
0.5 = (80-mean of sample)/12
Mean of sample= 74
I assume you're looking for the number:
0.5n + 9 = 21
- 9
0.5n = 12
÷ 0.5
n = 24
So the beginning number is 24, hope this helps!
Answer:
189
Step-by-step explanation:
let the number be n , then number multiplied by itself is n² and
n² = 567 × 63 = 35721 ( take square root of both sides )
n = 
= 189
