A perfect square refers to a number that is the result of multiplying an integer by itself. In this case, 6^1 is equal to 6.

However, 6 is not a perfect square because it cannot be obtained by multiplying an integer by itself. The perfect squares up to 6^1 would be 1^2 = 1 and 2^2 = 4.

Step-by-step explanation:

two polygons are similar if corresponding angles are congruent and corresponding sides are proportional

If two polygons are SIMILAR, then the corresponding sides must be proportional

The composition of two (or more) isometries is always an isometry

4. A rectangle has a length of 9 mm. A similar rectangle is drawn using a scale of 1:3. What is the length of the second rectangle?

9/1 = 1/3 so 9/3 = 3

Answer:

x = 10

Step-by-step explanation:

to find the measure of angles we first need to find the value of x

The sum of interior angles in a triangle is equal to 180

9x + 7x + 2x = 180 add like terms

18x = 180 divide both sides by 18

x = 10 to find angle measures replace x with 10 in each representative like:

m<L = 9x and 9*10 = 90 and so on

Answer:

false

the answer is x=70

The given Mayan number which is : :|| :|| in decimal (base 10) is 42.

The Mayan number system is a base-20 system that uses three symbols: a dot (.), a horizontal bar (|), and a shell-like symbol (:). The symbol for zero is a shell-like symbol (:).

To convert the given Mayan number to decimal (base 10), we need to understand the positional value of each symbol. Each position in the number represents a power of 20, with the rightmost position being 20⁰, the next position to the left being 20¹, and so on.

The Mayan number given, : :|| :||, can be broken down as follows:

The leftmost position has no symbol, which represents a value of 0.

The second position from the left has two shell-like symbols (:), which represents a value of 2x20¹ = 40.

The third position from the left has two horizontal bars (||), which represents a value of 2x20⁰ = 2.

The given Mayan number in decimal (base 10) is 40 + 2 = 42.

The option that has the correction justifications is the fourth option --- 1. Multiplication property of equality 2. Combine like terms 3. Addition property of equality 4. Division property of equality

From the question, we are to determine which of the given options has the correct justifications

To do this, we will solve the equation as well

The given equation is

x + 1/2(6x - 4) = 6

Multiply through by 2

2×x + 2×1/2(6x - 4) = 2×6

2x + (6x - 4) = 12

2x + 6x - 4 = 12

Combine like terms

8x - 4 = 12

Add 4 to both sides of the equation

8x - 4 + 4 = 12 + 4

8x = 16

Divide both sides of the equation by 8

8x/8 = 16/8

x = 2

From above, we can observe that the justifications used are

Multiplication property of equality

Combine like terms

Addition property of equality

Division property of equality

Hence, the option that has the correction justifications is the fourth option --- 1. Multiplication property of equality 2. Combine like terms 3. Addition property of equality 4. Division property of equality

Answer:

1. Multiplication property of equality

2. Combine like terms

3. Addition property of equality

4. Division property of equality

Step-by-step explanation:

Given equation:

\(x+\dfrac{1}{2} (6x-4) = 6\)

Wyatt's Step Work:

\(\textsf{1.} \quad 2x + 6x-4 = 12\)

\(\textsf{2.} \quad 8x-4 = 12\)

\(\textsf{3.} \quad 8x = 16\)

\(\textsf{4.} \quad x = 2\)

Step 1

Wyatt multiplied both sides of the equation by 2.

Multiplication property of equality:  When both sides of an equation are multiplied by the same number, the two sides remain equal.

Step 2

Wyatt added the terms with the variable x.

Combine like terms: When one term is made by adding/subtracting the coefficients and keeping the variables the same.

Step 3

Wyatt added 4 to both sides of the equation.

Addition property of equality:  When the same number is added to both sides of an equation, the two sides remain equal.

Step 4

Wyatt divided both sides of the equation by 8.

Division property of equality: When both sides of an equation are divided by the same number, the two sides remain equal.

The trigonometric function on the graph is:

f(x)= -cos(x)

So the correct option is B.

Here we can see the graph of a trigonometric function. We can see that the x-intercept is -1.

Notice that:

sin(0)= 0

cos(0) = 1

So the function can be an inversion over the x-axis of the cosine function, we coulod write this as:

f(x) = -cos(x)

That is the graphed function.

Deal A is better if the cost of one gallon of gas under Deal A is less than $3.82.

percentage, a relative value indicating hundredth parts of any quantity.

Deal A offers % off the price of the gas. Let's say the regular price per gallon is $x. Then, the discounted price per gallon would be:

x - 0.5x = 0.5x

So, the cost of one gallon of gas under Deal A would be 0.5x.

We don't know the regular price per gallon, but we do know that the cost of % gallons under Deal A is $15.70. So, we can set up the following proportion:

% / 1 = $15.70 / 0.5x

% = 15.7 / 0.5x

Deal B offers 11 gallons of gas for $42.00. So, the cost of one gallon of gas under Deal B would be:

$42.00 / 11 = $3.82 (rounded to two decimal places)

Therefore, Deal A is better if the cost of one gallon of gas under Deal A is less than $3.82.

Step-by-step explanation:

Mikey Johnson shipped out 34 2/7 pounds of electrical supplies. The supplies are placed in individual packets that weigh 2 1/7 pounds each. Therefore, Mikey shipped out 16 packets of electrical supplies.

To solve the problem, we can use the following steps.Step 1: Find the weight of each packet.

We are given that the weight of each packet is 2 1/7 pounds.

To convert this mixed number into an improper fraction, we can multiply the whole number by the denominator and add the numerator.

This gives us: 2 1/7 = (2 × 7 + 1) / 7= 15 / 7 pounds.

Therefore, the weight of each packet is 15/7 pounds.

Now, divide the total weight by the weight of each packet.

We are given that the total weight of the supplies shipped out is 34 2/7 pounds.

To convert this mixed number into an improper fraction, we can multiply the whole number by the denominator and add the numerator.

This gives us: 34 2/7 = (34 × 7 + 2) / 7= 240 / 7 pounds.

Therefore, the total weight of the supplies is 240/7 pounds.

To find the number of packets that Mikey shipped out, we can divide the total weight by the weight of each packet.

This gives us: 240/7 ÷ 15/7 = 240/7 × 7/15= 16.

Therefore, Mikey shipped out 16 packets of electrical supplies.

Carleigh, Inc. should separate the organ meats from the residual and sell them abroad, as it would increase their total revenue by $17,150 per week.

To determine whether Carleigh, Inc. should separate the organ meats and sell them abroad, we need to calculate the incremental revenue and incremental costs associated with this decision.

The incremental revenue would be the revenue generated from selling the organ meats abroad, which is $52,000 per week. The incremental cost would include the cost of further processing ($27,500 per week), transportation cost ($12,100 per week), and the increase in resource spending for other activities ($3,120 per week).

Therefore, the incremental cost would be $42,720 per week. Subtracting this from the incremental revenue of $52,000, we get an incremental profit of $9,280 per week.

However, this decision would also decrease the value of the residual from $9,800 to $2,650 per week. Therefore, we need to subtract this decrease in value from the incremental profit. This gives us a net increase in profit of $17,150 per week ($9,280 - $7,130).

Thus, it would be beneficial for Carleigh, Inc. to separate the organ meats and sell them abroad.
