Please help me (30 points) 1. A recipe calls for 2 1/3 cups of flour, 3/4 cups of white sugar, and 1/3 cups of brown sugar. The

Katena32 [7]

Lets find how much flour we need for just one serving.

2 2/3 ÷ 6

8/3 ÷ 6

8/3 * 1/6

8/18

4/9 cup of flour per serving

If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.

4/9 * 18/1

72/9

8 cups of flour for 18 servings

Best of Luck!

Patty prepared a simple salt solution using 3 parts salt and 4 parts water. Timmy made a salt solution using 6 parts salt and 7

777dan777 [17]

Answer:

The solution of Timmy is saltier.

Step-by-step explanation:

We have to keep in mind that a solution is saltier if and only if salt has a greater proportion within solution. The following criterion is used to determine which solution is saltier:

$r = \frac{n_{salt}}{n_{salt}+n_{water}}$

Where:

$r$ - Salt ratio, dimensionless.

$n_{salt}$ - Parts of salt, dimensionless.

$n_{water}$ - Parts of water, dimensionless.

Now, we find the salt ratios of Patty and Timmy:

Patty ( $n_{salt} = 3$ and $n_{water} = 4$ )

$r_{P} = \frac{3}{3+4}$

$r_{P} = \frac{3}{7}$

$r_{P} = 0.429$

Timmy ( $n_{salt} = 6$ and $n_{water} = 7$ )

$r_{T} = \frac{6}{6+7}$

$r_{T}= \frac{6}{13}$

$r_{T} = 0.462$

The solution of Timmy is saltier.

Solve equation <br> x^2+6x+1=0<br> give your answer to 2 decimal places

lakkis [162]

Step-by-step explanation:

x² + 6x + 1 = 0

(x + 3)² - 8 = 0

(x + 3)² = 8

x + 3 = √8 or x + 3 = -√8

x = √8 - 3 or x = -√8 - 3

x = -0.17 or x = -5.83.
