Use the Associative Property to find the value of the variable.

(8 x 15) x s = 8 x (15 x 11)

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.

Answer:

-84

Step-by-step explanation:

Let the number be x. Then we have,

[tex]\frac{x}{-7}[/tex] (the quotient of a number and -7)

[tex]\frac{x}{-7}-2[/tex] (decreased by 2)

[tex]\frac{x}{-7}-2=10[/tex] (is 10)

Now we can solve for x,:

[tex]\frac{x}{-7}-2=10[/tex]

[tex]\frac{x}{-7}=12[/tex]

[tex]x=-84[/tex]

So, the original number is -84

Answer:

-84

Step-by-step explanation:

[tex]\frac{n}{-7}[/tex] -2 = 10

add 2 to each side to get:

[tex]\frac{n}{-7}[/tex] = 12

multiply each side by -7 to get:

n = -84

Congruent triangles have congruent corresponding sides and angles, while similar triangles may or may not be congruent

The congruence statement is given as:

ΔPOG ≅ ΔSOR

The above means that:

Points P, O and G correspond to the points S, O and R

Hence, the corresponding side of PO in ΔPOG ≅ ΔSOR is SO

The congruence statement is given as:

ΔPOG ≅ ΔSOR

Hence, the congruent triangles are ΔPOG ≅ ΔROS

In figure 2, we have:

2 congruent sides, and 1 congruent angle between the congruent sides

Hence, the congruence postulate is SAS

The congruence statement is given as:

ΔABC ≅ ΔXYZ

The total percent of decrease in price of the shares of Selena's stock which Selena first buys and then sold is 11.5 percent.

Percentage decrease in a number is the ratio of total decrease in the original value of a number to the decreased value in the percentage form.

Given information-

The total stock buy by the Selena in $32.

The total stock sold by the Selena in $28.32.

As the total stock buy by the Selena in $32, and the total stock sold by the Selena in $28.32. Thus the total decrease in the price of stock is,

[tex]C_s=32-28.32\\C_s=3.68[/tex]

Thus the total decrease in the price of stock is $3.68.

As the cost price of the stock is $32 and the total decrease in the price of stock is $3.68. Thus the total percent of decrease in the price of the stock is,

[tex]\Delta C_s=\dfrac{3.68}{32}\times100\\\Delta C_s=11.5[/tex]

Thus the total percent of decrease in the price of the stock is 11.5 percent.
