The third congruent side is not included the side of angles thus it will be congruent by the AAS rule thus option (B) is correct.

If two figures are exactly the same in sense of their length side all things then they will be congruent.

In other meaning, if you can copy a figure then that copy and the original figure will be congruent.

As per the given two triangles,

The two angles are congruent.

The sides which are congruent in both triangles are not the common side of angles or not included in the side of angles thus it will be AAS congruency.

Hence "The third congruent side is not included the side of angles thus it will be congruent by the AAS rule".

By the use of the law of conservation of mass, the mass of the aluminum chloride is  267 g.

We know that a chemical reaction occurs when there is the combination of two or more substances such that a new substances is formed. We have to put down the reaction equation in this case and we have;

[tex]4Al(s) + 3ZnCl_{2} (aq) ---- > 2Al_{2} Cl_{3}(aq) +3 Zn(s)[/tex]

Using the law of the combination of mass, the total mass of the reactants must be equal to the total mass of the products; Let the mass of the aluminum chloride formed be x

Step-by-step explanation:

This is a special right triangle with side lengths 5-12-13 respectively.

If we can't remember the lengths we can use the following formula to calculate the lentgh of hypotenuse:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

the sum of square measure of both legs is equal to the square measure of hypotenuse

[tex] {5}^{2} + {12}^{2} = {c}^{2} [/tex]

25 + 144 = c^2

169 = c^2 find the root of both sides

13 = c, hypotenuse.

Answer:

156

Step-by-step explanation:

36*3=108

8*-6=-48

108-(-48)=156

The solution of the expression 36(3) - 8(-6) will be 156.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 36(3) - 8(-6). the expression will be solved as below,

E = 36(3) - 8(-6)

E = 108 - ( -48 )

E = 108 + 48

E = 156

No, this solution is not valid because of wrong concept and wrong calculations as he solved  [tex]\frac{10^{-7} }{10^{-2} }[/tex]  as [tex]10^{-7 + (-2)}[/tex]  but it should be solved as [tex]10^{-7-(-2)}[/tex] .

These exponents can be split since they all share the same base, x. You divide them by the highest exponent in the numerator (the numerator) and the lowest exponent in the denominator (the bottom exponent).

So according to it,

Part a:  The side of the square is found as 6 cm.

Part b: The side length of the square is found as 10 cm.

For the given dimensions for the question,

Part a: Area of square is same as area of rectangle.

Rectangle area = Length x breath

Rectangle area =  18 x 2

Rectangle area =  32 sq. cm

Now,

Area of square = Rectangle area

Area of square = side²

36 =  side²

side = √36

side = 6 cm.

Thus, the side of the square is found as 6 cm.

Part b: Side length of square.

Rectangle perimeter =  square perimeter

Rectangle perimeter =  2(length + width)

Rectangle perimeter =  2(18 + 2)

Rectangle perimeter =  40

square perimeter = 4 side

40 = 4 side

side = 40/4 = 10 cm.

Answer:

The amount of cholesterol in 11 ounces of lobster is 220 mg

Step-by-step explanation:

The amount of cholesterol in 11 ounces of lobster can be calculated as follows

The first step is to convert all units of measure from ounce to mg

1 gram = 0.0352 ounce

Divide both sides by 0.0352 to get the value of 1 ounce

[tex]\frac{1}{0.0352}[/tex] gram = [tex]\frac{0.0352}{0.0352}[/tex] ounce

28.35 gram = 1 ounce

Since 1 gram equals 1000 milligrams, then multiply the left side by 1000 and change the unit of measure to milligram

28.35 [tex]\times[/tex] 1000 mg = 1 ounce

28350 mg = 1 ounce

Convert 3.6 ounces to milligrams

3.6 ounces = 3.6 [tex]\times[/tex] 28350 mg

3.6 ounces = 102060 mg

Convert 11 ounces to milligrams

11 ounces = 11 [tex]\times[/tex] 28350 mg

11 ounces = 311850 mg

Since there are 72 mg of cholesterol in a 3.6 ounces serving of lobster, then the ratio equation to follow is

[tex]\frac{72}{102060}=\frac{x}{311850}[/tex]

Where x is the amount of cholesterol in 11 ounces of lobster

Multiply both sides by 311850 to isolate x

[tex]\frac{72}{102060}\times 311850=\frac{x}{311850}\times 311850[/tex]

[tex]\frac{22453200}{102060} =x[/tex]

Simplify the left side of the equation

220 = x

Since the value of x is 220, then the amount of cholesterol in  11 ounces of lobster is 220 mg

Answer:

n = 8

Step-by-step explanation:

to solve this equation you must first isolate the variable

that is n

so first

add 2n to both sides to get rid of n on one of the sides

-4n + 2n + 14 = -2 - 2n + 2n

-2n + 14 = -2

now subtract 14 to both sides to isolate n

-2n + 14 - 14 = -2 - 14

-2n = -16

now divide everything by -2 to isolate n completely

(-2n)/(-2) = (-16)/(-2)

n = 8

that is your answer

Answer:

[tex]\boxed{\sf n=8}[/tex]

Step-by-step explanation:

[tex]\sf -4n+14=-2-2n[/tex]

Subtract 14 from both sides:-

[tex]\sf -4n+14-14=-2-2n-14[/tex]

Simplify:-

[tex]\sf -4n=-2n-16[/tex]

Add 2n to both sides:-

[tex]\sf -4n+2n=-2n-16+2n[/tex]

Simplify:-

[tex]\sf -2n=-16[/tex]

Divide both sides by -2:-

[tex]\sf \cfrac{-2n}{-2}=\cfrac{-16}{-2}[/tex]
