Answer:

6 cups of water

Step-by-step explanation:

A recipe calls for 3 cups of sugar and 9 cups of water. How many should be used with 2 cups of sugar?

The question above, is solved below:

3 cups of sugar = 9 cups of water

2 cups of sugar = x

Cross Multiply

3x = 9 × 2

x = 18/3

x = 6

Hence, 2 cups of sugar = 6 cups of water

How do you factor this so you can find the roots or what x equals?
Marina86 [1]
Use the rational roots test.  The possible roots are: plus/minus 6,3,2,1

Use synthetic division and you will see that 3 is a root:

3 | 1 -3 -3 11 -6
   |    3  0  -9  6
   ____________
     1 0  -3   2 0

Use rational root again, to see that possible roots are: plus/minus 2,1

Try 2:

2 | 1 0 -3 -2
   |    2  4  2       
   _____________
     1  2  1  0

The above is x^2+2x+1 which is a perfect square: (x+1)^2

So we have the final factorization: (x-3)(x-2)(x+1)^2

So the roots are: 3, 2, -1
Where -1 is a double zero.

Mickey's savings account. $975 on deposit. 5.5% annual interest rate. Time is 3 months. Find the Interest
enot [183]

Answer:

$13.41

Step-by-step explanation:

1 year = 5.5%

1/4 year = 5.5/4%

1/4 year = 1.375%

975 * 1.01375 (because percents become fractions by dividing by 100) = 988.41

988.41 - 975 (because you're looking for the interest not what's his final amount) = 13.41

Find two positive numbers satisfying the given requirements. the product is 242 and the sum is a minimum. (smaller value) (large
Pepsi [2]

The two positive numbers satisfying the given requirements are 15.56 and 15.56

For given question,

Let x and y be  two positive numbers satisfying the given requirements.

⇒ xy = 242             .............(1)

The sum of given two positive numbers is a minimum.

Let the sum of given two positive numbers is S.

⇒ x + y = S             ............(2)

From equation(1),

⇒ y = 242/x

Substitute above value of y in equation (2),

⇒ x + y = S  

⇒ S = x + (242 / x)    

Now, for above equation we find the derivative of x with respect to x.

⇒ 0 = 1 - \frac{242}{x^{2} }

⇒ 242/x² = 1

⇒ x² = 242

⇒ x = ±15.56

Since the numbers are positive, x = 15.56

For x = 15.56

⇒ y = 15.56

Therefore, the two positive numbers satisfying the given requirements are 15.56 and 15.56
