Answer: 127

Step-by-step explanation:

yes, the person above me in the commets are right, for me 127

Answer:

Yes she is correct

Step-by-step explanation:

Suppose before we add and additional element x to a set A the number of subsets are n.

Now we can think of the subsets of the new set A union x as the subsets containing x and the subsets that are not containing x.

The subsets that are not containing x are exactly the former n subsets of A and the subsetes that are containing x is obtained by appending x to each of the n subsets. So we get another n subsets.

Therefore there are n + n =2n subsets which is double of the original subsets.

Therefore, there are n + n = 2n subsets which are doubled of the original subset.

Sets are the collection of well-defined elements. A set is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

Every time they add an element to a set, the number of subsets doubles.

Let the number of sets be n

But every time they add an element to a set, the number of subsets doubles.

Then according to the condition,

n + n = 2n

Therefore, there are n + n = 2n subsets which are doubled of the original subset.

Answer:

40

Step-by-step explanation:

Perimeter means add up all the sides

The top is 4+b, and b is 10, so the top and bottom are 14 each

The side is a which is 6 so

p=bottom+top+left side+right side

=14+14+6+6

=40

Step-by-step explanation:

Mark me brainest please. Hope this helps. Anna ♥

6 3/4 per hour or, in an hour

2 1/4 miles in 3/4 of an hour

2 1/4 miles = 9/4 miles in 1/3 of hour

9/4 miles divided by 1/3 hr

9/4 ÷ 1/3

Remember: Keep, Change Flip

9/4 x 3/1 = 27/4

Simplify:

27/4 = 6 3/4

So,

The answer is D

Step-by-step explanation:

Lets start off with the square roots:

[tex]\sqrt{16}[/tex] = 4

[tex]\sqrt{18}[/tex] = [tex]3\sqrt{2}[/tex] = 4.24264...

Mixed fraction:

[tex]4\frac{2}{3}[/tex] = 4.667

Therefore the answer is D.

Answer:

  d. √16, 4.23_23, √18, 4 2/3

Step-by-step explanation:

There are a couple of different ways to compare these numbers. Maybe one of the most straightforward is to find the decimal equivalent, rounded to hundredths.

  4.23_23 ≈ 4.23

  4 2/3 ≈ 4.67

  √18 ≈ 4.24

  √16 = 4.00

These can be sorted least-to-greatest by putting the first number (4.23) between the last two (4.00, 4.24) and reading the new list last-to-first.

  4.00, 4.23, 4.24, 4.67   ⇔   √16, 4.23..., √18, 4 2/3

_____

Additional comment

Another way to work this problem is to square the numbers not under a radical. 4.23...² ≈ 17.91 and (4 2/3)² ≈ 21.78. The ordering of the squares is the same as the ordering of their square roots.

  16 < 17.91 < 18 < 21.78   ⇔   √16 < 4.23... < √18 < 4 2/3

Answer:

[tex] (gof)(x) = g(f(x)) \\ = (3x)^{2} - 4(3x) - 6 \\ = 9 {x}^{2} - 12x - 6 \\ \\ (gof)(4) = g(f(4)) \\ = 9( {4}^{2} ) - 12(4) - 6 \\ = 9(16) - 48 - 6 \\ = 144 - 48 - 6 \\ = 90[/tex]

Step-by-step explanation:

Given that,

We have to calculate the area of the square.

⠀⠀⠀⠀⠀★ Area of square = (Side)² ★

[tex] \dashrightarrow \quad \rm { Area = [10 - 3x(-2)]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = [10 + 6x]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = (10)^2 + (6x)^2 + 2(10 \times 6x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = 100 + 36x^2 + 2(60x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \underline{\boxed{\bf { Area = 100 + 36x^2 + 120x \; cm^2}}} \\ [/tex]

[tex]\rule{200}2[/tex]

Answer:

36x^2 + 120x + 100 cm^2.

Step-by-step explanation:

[10 - 3x (-2)]

= 10 + 6x

The area = (10 + 6x)^2

= (10 + 6x)(10 + 6x)

= 10*10 + 10*6x + 10*6x + 6x*6x

= 100 + 60x + 60x + 36x^2

= 100 + 120x + 36x^2.

Answer:

30.5 meters

10.5 meters

Step-by-step explanation:

x = length

y = width

x = y + 20

2x + 2y = 82 (the perimeter of a rectangle)

using the first equation as substitute in the second equation we get

2×(y + 20) + 2y = 82

2y + 40 + 2y = 82

4y = 42

y = 42/4 = 21/2 = 10.5 meters

x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Answer:

About $0.539

Step-by-step explanation:

12.94 dollars / 24 bottles = $0.539

To convert the decimal 0.928 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

0.928 = 0.928

1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,

0.928

1

= (0.928 × 1000)

(1 × 1000)

= 928

1000

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(928,1000) = 8. So,

(928÷8)

(1000÷8)

= 116

125

when reduced to the simplest form.

hi <3

call your unknown variable 'x' and form an equation

9 - x = 7

subtract 9 from both sides

-x = -2

divide both sides by -1 to get your answer of:

x = 2

hope this helps :)

9-x=7

9-2=7

x=2

Answer:

It's A

Step-by-step explanation:

Using process of elimination B is wrong because even though you get 37 and 36 it multiplies them because of a lack of addition symbol. C is also wrong because it would turn out to be 12 x 13 which is larger than C so that's not it. in D 3x4 is 12 but it's added to 9 not multiplied so that's wrong which leaves you with A which is 9(3 + 4) = 63 and 27 + 36 = 63

Answer:

(a) Piece work pay is $90.6. (b) Hourly pay for the week is $304 (c) Total Pay for the week is $394.6

Step-by-step explanation:

Given,

Audrey receives a salary of $8 per hour.

Piecework pay is 12 cents per unit.  

Solve,

Part (a)

[tex]\begin{aligned}\rm{Audrey\; piece\;of \;work\; per\; unit}&=\$\dfrac{12}{100}\\&=\$0.12\end{aligned}[/tex]

Now,

The number of units produced by her in last week is 755 units.

Therefore,

[tex]\begin{aligned}\rm{Piece\;work\;pay}&=\rm{Total\;unit\;produced} \times \rm{pay\;per\;unit}\\&=755 \times 0.12\\&=\bold{\$90.6}\end{aligned}[/tex]

Part (b)

Audrey's hourly pay is $8.

She worked 38 hours last week.

Therefore,

[tex]\begin{aligned}\rm{Audrey's\;hourly\;pay\;for\;the\;week}&= \rm{Total\;time\;spend\;for\;the\;work }\times \rm{Hourly\;Pay}\\&=38 \times 8\\&=\bold{\$304}\end{aligned}[/tex]

Part (c)

Audrey's piecework pay for the week was $90.6 {This can be concluded from part (a)}.

Audrey's hourly pay for the week was $304  {This can be concluded from part (b)}.

Total pay for the week = Audrey's piecework pay for the week + Audrey's hourly pay for the week

Total pay for the week = $90.6+$304

                                      =$394.6

Part (d)

Audrey's piecework pay for the week was $90.6 when she produced 755 units.

Now, as per production, the pay will be $90.6 but for evaluating the total weekly salary, it is important to know about the time spend by Audrey to execute the whole work.
