Type the correct answer in the box. The solubility of calcium carbonate is 14. This rate means that 14 milligrams of calcium carbonate can dissolve in 1 liter of water. How much water would be required to fully dissolve 11 grams of calcium carbonate? Express your answer to the correct number of significant figures. One milligram is equal to 0. 001 grams. It would take liters of water to fully dissolve 11 grams of calcium carbonate.

Answers

Answer 1

Ratio compares two quantities. The amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

Given to us

The solubility of calcium carbonate is 14.

We know that to dissolve 14 milligrams of calcium carbonate we will need 1 liter of water. therefore, the ratio of water and calcium carbonate can be written as,

[tex]\rm \dfrac{calcium\ carbonate}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]

We need to find the amount of water needed to dissolve 14 grams of water, therefore, we will convert grams to milligrams,

1 gram = 1000 milligram

14 gram = 14,000 milligram

Using the same ratio,

[tex]\rm \dfrac{14,000\ milligram}{water} = \dfrac{14\ milligram}{1\ liter}[/tex]

[tex]\rm {water} = \dfrac{14000\ milligram \times 1\ liter}{14\ milligram}[/tex]

water = 1000 liters

Hence, the amount of water that will be needed to dissolve 14 grams of calcium carbonate is 1000 liters.

Three friends decide to rent an apartment and split the cost evenly. They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. If rent is $650 per month, how much was the security deposit? a. $10 b. $207 c. $620 d. $1,270 Please select the best answer from the choices provided A B C D.

Answers

Total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

What is monthly payment?

The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.

The rent of the apartment is $650 per month. The rent of the two months (first and last) is,

[tex]M=2\times650\\M=1300[/tex]

This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,

[tex]P=\dfrac{1300}{3}\\P=433.33[/tex]

They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. Therefore,

[tex]P=640-433P=206.67[/tex]

Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,

[tex]SD=206.67\times3\\SD=620.01[/tex]

Hence, total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

Answers

Answer:

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

Given

x² + y² + 10x - 6y + 14 = 0 ( collect the x/ y terms together and subtract 14 from both sides )

x² + 10x + y² - 6y = - 14

Using the method of completing the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(5)x + 25 + y² + 2(- 3)y + 9 = - 14 + 25 + 9

(x + 5)² + (y - 3)² = 20 ← in standard form
