Scorpion4ik [409]

Answer:

648 seconds

Step-by-step explanation:

First we need to see how much 60% of 756 is, so we multiply 756 × 0.60 and we get 453.6, so we now just need to see in how many seconds (0.7) we will get 453.6 oz, so we simply divide 453.6 ÷ 0.7 = 648. This is your answer. We can check this by multiplying 648 × 0.7 and getting 453.6

the difference between the squares of two numbers is 3. Twice the square of the first number increased by the square of the seco

Maurinko [17]

Answer:

The number are $\sqrt{6}$ and $\sqrt{6}$ .

Step-by-step explanation:

Given as :

The difference between the squares of two number = 3

And , Twice the square of the first number increased by the square of the second number is 9

Now, Let The first number = F

And The second number = S

So , According to question

F² - S² = 3 .......A

2 F² - S² = 9 ........B

Now, solving the equations

( 2 F² - S² ) - ( F² - S² ) = 9 - 3

Or, ( 2 F² - F² ) + ( S² - S² ) = 6

Or, F² + 0 = 6

∴ F = $\sqrt{6}$

Putting the value of F in eq A

So, ( $\sqrt{6}$ )² - S² = 3

Or, 6 - 3 = S²

Or, S² = 3

∴ S = $\sqrt{3}$

So, The number are $\sqrt{6}$ , $\sqrt{6}$

Hence The number are $\sqrt{6}$ and $\sqrt{6}$ . Answer
