A. A container holds 0.500 qt of liquid. How many milliliters of lemonade will it hold?

Nady [450]

Answer:

A container can hold 473.176 ml

42.52 grams is nitrogen.

Step-by-step explanation:

Part A:

We have given that a container holds 0.500 qt . Now we have to find how many milliliters of lemonade it can hold.

We know that 1 qt = 946.353 ml

To find how many milliliters of lemonade a container hold, we have to convert 0.500qt into ml.

As we have mentioned above that 1 qt = 946.353 ml

Multiply the volume value by 946.353 .

0.500 * 946.353

= 473.176 ml

It means a container can hold 473.176 ml

Part B:

Convert the unit oz to grams. The ratio is 1 ounce is to 28.34 grams.

We have 10.0 oz.

10* 28.34 = 283.495

This would mean 10 oz is equivalent to 283.50 grams. It is given that the fertilizer is 15% by mass nitrogen. It means for every 100 g of fertilizer 15 grams of that is nitrogen. Hence for every 283.50 grams of fertilizer

283.50 * (15/100) = 42.52 grams is nitrogen.

Vera is using her phone.Its battery life is down to 2/5,and it drains another 1/9 every other. How many hours will her battery l

Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

$1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

$\frac{1}{9}\cdot x=\frac{3}{5}$

Now we will solve for x.

$x=\frac{3\cdot 9}{5}=\frac{27}{5}$

$x=(5+\frac{2}{5})hours$

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

$60\cdot \frac{2}{5}=24\text{minutes}$

Therefore, remaining battery life will be 5 hours and 24 minutes.

You will be brainliest please list correct answer and the mistake he made

anzhelika [568]

Hey There!!

The answer is below!!

Step-by-step explanation:

We move all terms to the left:

$-6n+22-(-4n+14-10n+22)=0$

We add all the numbers together, and all the variables

$-6n-(-14n+36)+22=0$

We get rid of parentheses

$-6n+14n-36+22=0$

After that, We add all the numbers together, and all the variables

$8n-14=0$

Then, We move all terms containing n to the left, all other terms to the right

$8n=14$

$n=14/8$

$n=1+3/4$

I don't know this is $100$ % right....

$So.....GoodLuck!!$

# $Be$ $Bold$

# $Always$ $Brainly!$
