How many solutions does the following equation have?<br> -4(+5) = -4- 20
Rus_ich [418]

Answer:

0

Step-by-step explanation:

Try looking at it in 2 ways- left side and right side. On the left side we have -4*5, which equals -20. On the right we have -4-20, which equals -24. so then when we add it all together (not literally) we get -20=-24. Since -20 and -24 obviously do not equal eachother, there is no solution.

A. A container holds 0.500 qt of liquid. How many milliliters of lemonade will it hold?
Nady [450]

Answer:

<em>A container can hold 473.176 ml</em>

<em>42.52 grams is nitrogen. </em>

Step-by-step explanation:

<u>Part A:</u>

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

<em>It means a container can hold 473.176 ml</em>

<u>Part B:</u>

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

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

<em></em>
